VIP2 Upgrade Prerequisites

This section provides guidelines for when to upgrade the SRAM and DRAM (or SDRAM) on your VIP2 and a list of parts and tools you will need to perform the upgrade; it also includes safety and ESD-prevention guidelines to help you avoid injury and damage to the equipment.

DRAM and SRAM Upgrade Guidelines

Use the following recommended guidelines to determine when to upgrade DRAM (or SDRAM) and SRAM and your VIP2. You cannot use DRAM designed for the Route Switch Processor (RSP) on the VIP2 models.

Note   The minimum recommended VIP2 model is a VIP2-15; however, the maximum transmission unit (MTU) sizes available for two high-speed, high-bandwidth port adapters on a VIP2 might require the additional VIP2 SRAM available on the VIP2-40 model or greater, to ensure adequate packet buffers.

Table 1 provides information about which VIP2 models to use for distributed switching (DSW) and distributed services (DS).

Note   When DSW is enabled, the routing table generated by the RSP or RSP7000 is downloaded to VIP2 DRAM. Depending on the size of the routing table, it may become necessary to upgrade to the VIP2-40 if you are using a VIP2-20.

List of Parts and Tools

You need the following tools and parts to upgrade a VIP2. If you need additional equipment, contact a service representative for ordering information.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

Caution   For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Removing a VIP2

The VIP2 supports online insertion and removal (OIR); therefore, you do not need to shut down the interface or the system power when removing a VIP2. Further, you do not need to disconnect cables from VIP2 ports before you remove a VIP2.

Figure 6 shows proper handling of an interface processor during installation.

Use the following procedure to remove a VIP2:

Caution   Always use the ejector levers to remove or install the VIP2. Failure to do so can cause erroneous system error messages indicating a board failure.

Step 2   Place your thumbs on the ejector levers and simultaneously pull both of the ejectors outward (in the opposite direction from that show in Figure 7c) to release the VIP2 from the backplane connector.

Step 3   Using the VIP2 handle, carefully pull the VIP2 straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 6.) Keep the VIP2 parallel to the backplane.

Step 4   Place the removed VIP2 on an antistatic mat or foam pad, or place it in an antistatic bag if you plan to return it to the factory.

Step 5   If the interface processor slot is to remain empty, install a filler (MAS7K-BLANK) to keep dust out of the chassis and to maintain proper air flow inside the chassis. Do not leave the interface processor slot open.

Note   After you remove the VIP2, proceed to the "Installing the VIP2-10, VIP2-15, VIP2-20, VIP2-40 and VIP2-50 Memory Upgrade Kits" section, or to the "Installing the VIP2-50 Memory Upgrade Kits" section, and then to the "Replacing a VIP2" section.

This completes the removal of a VIP2 procedure.

Installing the VIP2-10, VIP2-15, VIP2-20, VIP2-40 and VIP2-50 Memory Upgrade Kits

This section provides the guidelines and procedures for upgrading the VIP2-10, VIP2-15, VIP2-20, VIP2-40, and VIP2-50 memory devices.

The following memory kits are compatible with the VIP2-10, VIP2-15, and VIP2-20:

The following memory kit is compatible with the VIP2-40: MEM-VIP240-64MB-D=, which upgrades a VIP2-40 to 64 MB of DRAM, with two 32-MB DRAM SIMMs. This memory kit is available in a 10 package, part number MEM-VIP240-64MB-10PK=.

The following memory kits are compatible with the VIP2-50: MEM-VIP250-64MB-D=, which upgrades a VIP2-50 to 64 MB of DRAM, with two 32-MB DRAM SIMMs, and the MEM-VIP250-128MB-D=, which upgrades a VIP2-50 to 128 MB of DRAM, with one 128-MB DRAM SIMMS. These memory kits are available in a 10 package, part numbers MEM-VIP250-64MB-10PK= and MEM-VIP250-128-10PK=.

To upgrade memory on your VIP2-10, VIP2-15, and VIP2-20, you must replace both the SRAM and DRAM (except the memory kits MEM-VIP240-64MB-D=, MEM-VIP250-64MB-D=, and MEM-VIP250-128MB-D=, which requires you to replace only the DRAM SIMMs on your VIP2-40 or VIP2-50). Only 70-nanosecond (ns) DRAM SIMMs and a 12-ns SRAM DIMM should be used. A Cisco manufacturing part number appears on the SIMMs and the DIMM.

Figure 8 shows the locations of the DRAM SIMMs and the SRAM DIMM on the VIP2-10, VIP2-15, VIP2-20, and VIP2-40.

The following sections provide DRAM and SRAM upgrade procedures for the VIP2-10, VIP2-15, VIP2-20, and VIP2-40 (DRAM only) models:

Replacing VIP2-10, VIP2-15, VIP2-20, VIP2-40, or VIP2-50 DRAM SIMMs

The 70-nanosecond (ns) DRAM on the VIP2-10, VIP2-15, VIP2-20, VIP2-40, VIP2-50 (hereafter called the VIP2) is contained in two single in-line memory modules (SIMMs) located in sockets U2 and U6. (See Figure 8.) Depending on your system configuration, a memory upgrade may be required. Also, if you is determine that a system problem is caused by a SIMM, a SIMM replacement may be required.

Note   The memory kit MEM-VIP240-64MB-D= requires you to replace only the DRAM SIMMs on your VIP2-40.

Caution   To prevent ESD damage, handle SIMMs by the card edges only. Place removed SIMMs on an antistatic mat and store them in an antistatic bag.

Removing VIP2 DRAM SIMMs

Use the following procedure to remove DRAM SIMMs:

Step 2   Place the VIP2 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as a wrist strap. Position the VIP2 so that the handle is away from you, and the bus connector is toward you—opposite of the position shown in Figure 8.

Step 3   Locate the SIMMs. The DRAM SIMMs occupy sockets U2 and U6. (See Figure 8.)

Step 4   Release the spring clips from the SIMM that you want to remove and release the SIMM from the socket. (See Figure 9.)

Step 5   When both ends of the SIMM are released from the socket, grasp the ends of the SIMM with your thumb and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only; avoid touching the memory module, pins, or traces (the metal fingers) along the socket edge. (See Figure 10.)

Step 6   Place the SIMM in an antistatic bag to protect it from ESD damage.

Step 7   Repeat Steps 4 through 6 for the remaining SIMM, as required for this replacement.

This completes the SIMM removal procedure. Proceed to the next section to install the new SIMMs.

Installing New VIP2 DRAM SIMMs

SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 10.)

Caution   To prevent ESD damage, handle DRAM SIMMs as shown in Figure 10.

Note   The memory kit MEM-VIP240-64MB-D= requires you to replace only the DRAM SIMMs on your VIP2-40.

Use the following procedure to install new DRAM SIMMs:

Step 2   Hold the SIMM between your thumbs and forefingers, component-side-up, with the connector edge (the metal fingers) away from you.

Step 3   Tilt the SIMM to approximately the same angle as the socket and insert the connector edge into the socket.

Caution   When inserting SIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP2 to the factory for repair.

Step 4   Gently push the SIMM into the socket until the spring clips snap over the ends of the SIMM. If necessary, rock the SIMM gently back and forth to seat it properly.

Step 5   Repeat Steps 2 through 5 for the remaining SIMMs.

Step 6   When both SIMMs are installed, check all four alignment holes (two on each SIMM) and ensure that the spring clip is visible. If it is not, the SIMM is not seated properly. If any SIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SIMM firmly back into the socket until the spring clips snap into place.

This completes the DRAM SIMM replacement procedure. If you need to replace the SRAM DIMM, proceed to the "Replacing the VIP2-10, VIP2-15, or VIP2-20 SRAM DIMM" section, and then reinstall the VIP2 in the chassis. (Follow the steps in the "Replacing a VIP2" section.)

If you do not need to replace the SRAM DIMM, refer to the "Checking the VIP2 Memory Upgrade" section, as required.

Replacing the VIP2-10, VIP2-15, or VIP2-20 SRAM DIMM

The SRAM on the VIP2-10, VIP2-15, and VIP2-20 (hereafter called the VIP2) is contained in one dual in-line memory module (DIMM) located in socket U5. (See Figure 8 on page 15.) Depending on your system configuration, a memory upgrade may be required. Also, if you determine that a system problem is caused by the DIMM, a DIMM replacement may be required.

Caution   To prevent ESD damage, handle the DIMM by the edges only. Place a removed DIMM on an antistatic mat and store it in an antistatic bag.

Removing the VIP2 SRAM DIMM

Use the following procedure to remove the SRAM DIMM:

Step 2   Place the VIP2 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as a wrist strap. Position the VIP2 so that the handle is toward you and the bus connector is facing away from you, approximately as shown in Figure 8.

Step 3   Locate the DIMM. The SRAM DIMM occupies socket U5. (See Figure 8.)

Step 4   Locate the release lever on the DIMM socket (see circle in Figure 11) and release the DIMM from the socket as shown.

Step 5   When one end of the DIMM is released from the socket, grasp the ends of the DIMM with your thumb and forefinger and pull the DIMM completely out of the socket. Handle the edges of the DIMM only. (See Figure 12.)

Step 6   Place the DIMM in an antistatic bag to protect it from ESD damage.

This completes the DIMM removal procedure. Proceed to the next section to install the new DIMM

Installing a New VIP2 SRAM DIMM

The SRAM DIMM is a sensitive component that is susceptible to ESD damage. Handle the DIMM by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the DIMM). (See Figure 12.)

Caution   To prevent ESD damage, handle the DIMM as shown in Figure 12.

Use the following procedure to install a new SRAM DIMM:

Step 2   Hold the DIMM between your thumbs and forefingers, component-side-up, with the connector edge (the metal fingers) down. (See Figure 12.)

Step 3   Tilt the DIMM to approximately the same angle as the socket and insert the connector edge into the socket. Note the two notches (keys) on the connector edge of the DIMM. (See Figure 12.) These keys are intended to assure correct orientation of the DIMM in the socket.

Caution   When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP2 to the factory for repair.

Step 4   Note the orientation of the socket key on the SRAM DIMM and the DIMM socket, and gently push the DIMM into the socket until the release lever is flush against the side of the DIMM socket (see Figure 13) and the DIMM edge connector is fully inserted. If necessary, rock the DIMM gently back and forth to seat it properly.

Step 5   When the DIMM is installed, check that the release lever is flush against the side of the DIMM socket. (See Figure 13.) If it is not, the DIMM may not be seated properly. If the DIMM appears misaligned, carefully remove it according to the removal procedure, and reseat it in the socket. Push the DIMM firmly back into the socket until the release lever is flush against the side of the DIMM socket.

Step 6   Reinstall the VIP2 in the chassis. (Follow the steps in the "Replacing a VIP2" section.)

This completes the SRAM DIMM replacement procedure.

Proceed to the "Replacing a VIP2" section to replace the VIP2 in the chassis; then restart the system for an installation check. Refer to the "Checking the VIP2 Memory Upgrade" section, as required.

Installing the VIP2-50 Memory Upgrade Kits

This section provides the guidelines and procedures for installing VIP2-50 memory devices. The 10-nanosecond (ns) SDRAM on the VIP2-50 is contained in one dual in-line memory module (DIMM), and the SRAM on the VIP2-50 is contained in one proprietary daughter card. (See Figure 14.)

Depending on your system configuration, a memory upgrade may be required. Also, if you determine that a system problem is caused by the SDRAM DIMM or SRAM daughter card, a replacement may be required.

The following Cisco Systems memory kits are available and compatible with the VIP2-50:

Figure 14 shows the locations of the SRAM daughter card and SDRAM DIMM on the VIP2-50.

The following sections provide SDRAM and SRAM upgrade procedures for the VIP2-50:

The procedures in this section are required only if you have a VIP2-50 and need to upgrade or replace the SDRAM DIMM.

Note   Use only the SDRAM DIMM from Cisco Systems. A Cisco manufacturing part number appears on the SDRAM DIMM.

Caution   To prevent ESD damage, handle the DIMM by the card edges only. (See Figure 17 on page 23.) Place a removed DIMM on an antistatic mat and store it in an antistatic container.

Removing a VIP2-50S DRAM DIMM

Use the following procedure to remove the existing DIMM:

Step 2   Place the VIP2-50 on an antistatic mat or pad and ensure that you are wearing an antistatic device, such as a wrist strap. Position the VIP2-50 so that the handle is away from you and the bus connector is toward you—opposite of the position shown in Figure 14.

Step 3   Locate the DIMM. (See Figure 14.)

Step 4   Open the DIMM socket tabs on the DIMM to release the DIMM from the socket. (See Figure 15.) The DIMM is under tension in the socket; therefore, the DIMM may release from the socket with some force.

Step 5   With the DIMM socket tabs open, grasp the ends of the DIMM between your thumbs and forefingers and pull the DIMM completely out of the socket. (See Figure 16.) Handle the edges of the DIMM only; avoid touching the memory module, pins, or traces (the metal fingers) along the socket edge. (See Figure 17.)

Step 6   Place the DIMM in an antistatic container to protect it from ESD damage.

This completes the DIMM removal procedure. Proceed to the next section to install a new DIMM.

Installing a New VIP2-50 SDRAM DIMM

The DIMM is a sensitive component that is susceptible to ESD damage. Handle the DIMM by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the DIMM). (See Figure 17.)

Caution   To prevent ESD damage, handle the DIMM as shown in Figure 17.

With the VIP2-50 in the same orientation as the previous procedure (with the handle toward you and the bus connector away from you), you will install the SRAM daughter card in the socket, as described in the following procedure:

Step 2   Hold the DIMM between your thumbs and forefingers component-side-up. (See Figure 17.)

Step 3   Tilt the DIMM to approximately the same angle as the socket and insert the connector edge into the socket.

Caution   When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP2-50 to the factory for repair.

Step 4   Gently push the DIMM into the socket until the socket tabs close over the ends of the DIMM. (See Figure 18.) If necessary, rock the DIMM gently back and forth to seat it properly.

Step 5   When the DIMM is installed, check to see it is seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until the socket tabs move into place.

This completes the DIMM replacement procedure. If required, proceed to the "Replacing the VIP2-50 SRAM Daughter Card" section. Otherwise, reinstall the VIP2 in the chassis. (Follow the steps in the "Replacing a VIP2" section.) Refer to the "Checking the VIP2 Memory Upgrade" section, as required.

Replacing the VIP2-50 SRAM Daughter Card

The procedures in this section are required only if you have a VIP2-50 and need to upgrade or replace the SRAM daughter card.

Note   Use only the SRAM daughter card from Cisco Systems. A Cisco manufacturing part number appears on the SRAM daughter card.

Caution   To prevent ESD damage, handle the SRAM daughter card by the edges only. Place a removed SRAM daughter card on an antistatic mat and store it in an antistatic container.

Removing a VIP2-50 SRAM Daughter Card

Use the following procedure to remove the existing SRAM daughter card:

Step 2   Place the VIP2-50 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as a wrist strap. Position the VIP2-50 so that the handle is toward you and the bus connector is facing away from you, approximately as shown in Figure 14.

Step 3   Locate the SRAM daughter card on the VIP2-50. (See Figure 14.) The SRAM daughter card has a release lever that loosens the daughter card from its socket.

Caution   To prevent damage to the SRAM daughter card in the steps that follow, do not open the release lever on the daughter card's socket until after you remove the three screws located at the rear of the SRAM daughter card. (See Figure 20.) Further, do not reinstall the three screws until after you install the SRAM daughter card in the socket and ensure that the release lever is flush against the side of the socket.

Note   Figure 20 and Figure 21 show the functions of the release lever on the SRAM daughter card socket. To release an SRAM daughter card from the socket, first remove the three screws, then open the release lever, as shown in Figure 19. When you insert an SRAM daughter card in the socket, the release lever should close automatically, as shown in Figure 21.

Step 4   Locate the three screws that secure the SRAM daughter card to the motherboard. (See item 1 in Figure 19.)

Note   The SRAM daughter card lays parallel to the motherboard when the daughter card connector edge is installed in the socket.

Step 5   Using a Number 1 Phillips screwdriver, carefully remove the three screws from the SRAM daughter card (see Figure 19), and then set them aside.

Step 6   Locate the release lever on the socket. (See Figure 19.) Open the release lever to release the SRAM daughter card from the socket.

Step 7   When one end of the SRAM daughter card is released from the socket, carefully pull the card away from the socket and motherboard. Handle the edges of the SRAM daughter card only. (See Figure 22.)

Step 8   Place the SRAM daughter card in an antistatic container to protect it from ESD damage.

This completes the SRAM daughter card removal procedure. Proceed to the next section to install a new SRAM daughter card.

Installing a New VIP2-50 SRAM Daughter Card

The SRAM daughter card is a sensitive component that is susceptible to ESD damage. Handle the SRAM daughter card by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SRAM daughter card). (See Figure 22.)

Caution   To prevent ESD damage, handle the SRAM as shown in Figure 22.

With the VIP2-50 in the same orientation as the previous procedure (with the handle toward you and the bus connector away from you), you will install the SRAM daughter card in the socket, as described in the following procedure:

Step 2   Hold the SRAM daughter card between your thumbs and forefingers, component-side-up, with the connector edge (the metal fingers) toward you. (See Figure 22.)

Step 3   Tilt the SRAM daughter card parallel with the socket and insert the connector edge into the socket. Note the two notches (keys) on the connector edge of the SRAM daughter card. (See Figure 23.) These keys are intended to assure correct orientation of the SRAM daughter card in its socket.

Caution   When inserting the SRAM daughter card, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP2-50 to the factory for repair.

Step 4   Note the orientation of the socket keys on the SRAM daughter card (see Figure 23) and the socket, and gently push the SRAM daughter into the socket until the release lever is flush against the side of the socket (see Figure 21) and the SRAM daughter card edge connector is fully inserted. If necessary, rock the SRAM daughter card gently back and forth to seat it properly.

Note   When the SRAM daughter card is properly inserted in the socket, the three screw holes at the rear of the card should align with the standoffs below the card, and the release lever should be flush against the side of the socket.

Step 5   Ensure that the release lever is flush against the side of the socket. If it is not, the SRAM daughter card may not be seated properly. If the SRAM daughter card appears misaligned, carefully remove it, and reseat it in the socket. Push the SRAM daughter card firmly back into the socket until the release lever is flush against the side of the socket.

Step 6   Verify that the three screw holes at the rear of the SRAM daughter card align with the standoffs below the SRAM daughter card; using the Number 1 Phillips screwdriver, reinstall the three screws. (See Figure 19.)

Step 7   Reinstall the VIP2-50 in the chassis. (Follow the steps in the "Replacing a VIP2" section.

This completes the VIP2-50 SRAM daughter card replacement procedure. To verify that the upgrade was successful, refer to the "Checking the VIP2 Memory Upgrade" section.

Replacing a VIP2

This section provides the procedure for replacing a VIP2 in your system. The processor modules are oriented horizontally in the Cisco 7010 and Cisco 7505 and vertically in the Cisco 7000, Cisco 7507, and the Cisco 7513. The VIP2 slides into an open interface processor slot and connects directly to the backplane. The interface processor slots are keyed to guide pins on the backplane, so the VIP2 can be installed only in an interface processor slot. Figure 7 shows the functional details of inserting an interface processor and using the ejector levers. Figure 6 shows proper handling of an interface processor during installation.

Caution   Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete its discovery and initialization before removing or inserting another interface processor. Disrupting the sequence before the system has completed verification can cause the system to interpret hardware failures.

Use the following procedure to install a VIP2:

Step 2   Hold the VIP2 handle with one hand and place your other hand under the carrier to support the VIP2 and guide it into the slot. (See Figure 6.) Avoid touching the VIP2 or any connector pins.

Caution   To prevent ESD damage, hold interface processors by the handles and carrier edges only.

Step 3   As you place the back of the VIP2 in the slot, align the notch on the carrier with the groove in the slot. (See Figure 7.)

Step 4   While keeping the VIP2 parallel to the backplane, carefully slide it into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 7b.)

Caution   Always use the ejector levers when installing or removing processor modules. A module that is partially seated in the backplane will cause the system to pause indefinitely and subsequently crash, and shoving or slamming the interface processor into the slot can damage the backplane pins and board.

Step 5   Using your thumbs, simultaneously push both ejector levers inward until the VIP2 is pushed entirely into its slot. (See Figure 7c.)

Step 6   Tighten both of the captive installation screws.

Caution   To ensure proper electromagnetic interference (EMI) isolation for the chassis, make certain to tighten the captive installation screws on each VIP2 immediately after you install it and before proceeding with the installation of each remaining VIP2.

The VIP2 is now properly installed in the chassis.

Refer to the "Checking the VIP2 Memory Upgrade" section, as required.

Checking the VIP2 Memory Upgrade

After you upgrade the VIP2 and reconnect cables, verify the upgrade by observing the LED states and the console display. When the system has reinitialized all interfaces, the enabled LED on the VIP2 and on all interface processors should go on. Port adapter LEDs should be on, depending on your connection. The console screen will display a message as the system discovers each interface during its reinitialization.

If, after you have replaced SIMMs and the DIMM, the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:

If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.

Use the following procedure to verify that the VIP2 is installed correctly:

Step 2   When the reinitialization is complete, verify that the enabled LED on each port adapter goes on and remains on. If it does, proceed to Step 5. If it does not, proceed to the next step.

Step 3   If the enabled LED on a port adapter fails to go on, suspect that the VIP2 board connector is not fully seated in the backplane. Loosen the captive installation screws, then firmly push both ejector levers into place until they are approximately in the same orientation as the VIP2 faceplate. Tighten the captive installation screws. After the system reinitializes the interfaces, the enabled LED on the port adapter should go on. If it does, proceed to Step 5. If it does not, proceed to Step 4.

Step 4   If the enabled LED still fails to go on, remove the VIP2 and try installing it in another available interface processor slot.

Step 5   Use the show interfaces type slot/port adapter/port or show controllers cbus commands to verify the status of the interfaces.

Step 6   When the interfaces are up, check the activity of each interface by observing the status LEDs, which are described in the LED section of your port adapter manual.

Step 7   In general, if an interface's LED fails to go on and a cable is connected to the port, check the cable connection and make certain it is properly seated in the connector.

If an error message is displayed on the console terminal, refer to the System Error Messages publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.

This completes the VIP2 memory upgrade procedure.
