Note The Telco and EIA Shelf Bracket Kit is not intended for use with a Cisco MDS 9513 Director or Cisco MDS 9509 Director in a two-post telco rack.
Installation Guidelines
Follow these guidelines when installing the Cisco MDS 9500 Series:
•Plan your site configuration and prepare the site before installing the chassis. Cisco recommends you to use the site planning tasks listed in Appendix D, "Site Planning and Maintenance Records."
•Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate airflow (airflow requirements are listed in Appendix B, "Technical Specifications").
•Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix B, "Technical Specifications".
•Ensure that the cabinet or rack meets the requirements listed in Appendix A, "Cabinet and Rack Requirements."
Note Jumper power cords are available for use in a cabinet. For more information, see the "Jumper Power Cord" section on page C-12.
•Ensure that the chassis is adequately grounded. Grounding the chassis is recommended in all cases, and is mandatory for Cisco MDS 9506 Directors that have a DC power supply installed. If the switch is not mounted in a grounded rack or cabinet, Cisco recommends connecting the system ground on the chassis and the power supply ground to an earth ground, regardless of whether the power supplies are AC or DC.
•Ensure that the site power meets the power requirements listed in Appendix B, "Technical Specifications." You can use an uninterruptible power supply (UPS) to protect against power failures.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco MDS 9000 Family, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.
•Ensure that circuits are sized according to local and national codes. For North America:
–The 1900-W AC power supplies require a 20-A circuit.
–The 1900-W DC power supplies require a 70-A circuit.
–The 2500-W AC power supplies require a 20-A circuit.
–The 2500-W DC power supplies require a 100-A circuit.
–The 4000-W AC power supplies require a 30-A circuit.
–The 6000-W AC power supplies require two 220 V inputs at 20-A circuit.
If you are using 200/240 VAC power sources in North America, the circuits must be protected by two-pole circuit breakers.
Caution To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power are within the current ratings of the wiring and breakers.
•Record your installation and configuration information as you work. See Appendix D, "Site Planning and Maintenance Records."
•Use the following screw torques when installing the switch:
–Captive screws: 4 in-lb
–M3 screws: 4 in-lb
–M4 screws: 12in-lb
–M6 screws: 20in-lb
–10-32 screws: 20in-lb
–12-24 screws: 30in-lb
Required Equipment
Gather the following items before beginning the installation:
•Number 1 and number 2 Phillips screwdrivers with torque capability.
•3/16-inch flat-blade screwdriver.
•Tape measure and level.
•ESD wrist strap or other grounding device.
•Antistatic mat or antistatic foam.
•In addition to the grounding items provided in the accessory kit, you need the following items:
–Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the Cisco MDS 9500 to proper grounding facilities.
–Crimping tool large enough to accommodate girth of lug.
–Wire-stripping tool.
•For DC power supplies in a Cisco MDS 9506 Director, you need two 10-32 ring lugs for each DC power supply.
•For the Cisco MDS 9513 Director, you need a mechanical lift to handle the weight of the chassis.
Unpacking and Inspecting the Switch
Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. Statement 5
Caution Use a mechanical lift to lift the MDS 9513 chassis. The Cisco MDS 9513 Director can weigh up to 375 lb (170 kg) when fully loaded, depending on what modules populate the chassis.
Caution Cisco recommends that a third person assist whenever the chassis is being moved or lifted. The Cisco MDS 9509 Director weighs approximately 170 lb (77 kg) when fully loaded, and the Cisco MDS 9506 Director weighs approximately 125 lb (57 kg) when fully loaded with all modules and power supplies.
Caution When handling switch components, wear an ESD strap and handle modules by the carrier edges only. An ESD socket is provided on the chassis. For the ESD socket to be effective, the chassis must be grounded either through the power cable, the chassis ground, or metal-to-metal contact with a grounded rack.
Tip Keep the shipping container for use when moving or shipping the chassis in the future. The shipping carton can be flattened and stored with the pallet.
Note If you purchased this product through a Cisco reseller, contact the reseller directly for technical support. If you purchased this product directly from Cisco Systems, contact Cisco Technical Support at this URL: http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml.
Note The switch is thoroughly inspected before shipment. If any damage occurred during transportation or any items are missing, contact your customer service representative immediately.
To inspect the shipment, follow these steps:
Step 1 Compare the shipment to the equipment list provided by your customer service representative and ensure that you have received all items, including the following:
•Print documentation and CD-ROMs
•Grounding lug kit

Installing the Cisco MDS 9509 Director in a Rack
Caution If connecting a Cisco MDS 9509 Director to a 110-VAC power system, ensure that sufficient power is provided to meet the chassis power requirements for the number of modules installed.
When connected to 220 VAC, the 2500-W AC power supplies (DS-CAC-2500W) for the Cisco MDS 9509 Director are designed to provide an output power of 2331 W to power the modules and fans. When connected to a 110 VAC power system, the power supply provides approximately 1150 W. In this case, and if the power supplies are used in redundant rather than combined mode, they might not provide adequate power, depending on the number of modules loaded in the chassis.
If a 110-VAC input is chosen, a 110-VAC power cord (CAB-7513AC=) must be ordered separately.
Table 2-2 lists the items provided in the Cisco MDS 9509 rack-mount kit.
Note The rack-mount kit for the Cisco MDS 9509 Director includes side rack-mount brackets, which are required for the duration of the installation only and can be removed once the front rack-mount brackets are securely fastened to the rack-mounting rails.
Note The Cisco MDS 9500 Shelf Bracket Kit can be purchased as an optional shelf bracket kit for the Cisco MDS 9509 Director. See "Cisco MDS 9500 Shelf Bracket" section on page A-12.

To install the Cisco MDS 9506 chassis in the rack using the rack-mount kit, follow these steps:
Step 1 Place all the parts and screwdrivers near the rack for easy access while attaching the switch to the rack.
Note The front rack-mount brackets are shipped installed on the switch. If they have been uninstalled, reinstall them on the switch using the M4 x 6-mm screws.
Step 2 Position a person at each side of the chassis. Grasp the bottom of the chassis and slowly lift the chassis in unison, avoiding sudden twists or moves to prevent injury. Insert the rear of the chassis between the front mounting rails (see Figure 2-9), supporting the switch inside the rack until the next step is complete.
Step 3 If you are installing the optional cable management bracket, align the holes in the cable management bracket with the holes in the front, right rack-mount brackets and the mounting rail. Ensure that the chassis is level, and pass the screws through the cable management brackets and front rack-mount bracket and into the mounting rail.
Note Because the fan tray is on the left side of the chassis, Cisco recommends using only the right side for cable management. This allows easy removal of the fan tray if you need to replace a fan.
Step 4 Align the holes in the front rack-mount bracket with the holes in the mounting rail, and ensure that the chassis is level. Insert the 12-24 x 3/4-inch or 10-32 x 3/4-inch screws (depending on the type of holes in the mounting rails) through the holes in the front rack-mount bracket and into the holes in the mounting rails, using four screws per side.
Caution Use a minimum of four screws per side to ensure that the switch is adequately supported by the front rack-mount brackets.
System Grounding
This section describes the need for system grounding and explains how to prevent damage from electrostatic discharge.
Proper Grounding Practices
Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. Table 2-4 lists grounding best practices.
Table 2-4 Grounding Best Practices
Environment
|
Electromagnetic Noise Severity Level
|
Grounding Recommendations
|
Commercial building is subjected to direct lightning strikes.
For example, some places in the United States, such as Florida, are subject to more lightning strikes than other areas.
|
High
|
All lightning protection devices must be installed in strict accordance with manufacturer recommendations. Conductors carrying lightning current should be spaced away from power and data lines in accordance with applicable recommendations and codes. Appropriate grounding practices must be closely followed.
|
Commercial building is located in an area where lightning storms frequently occur but is not subject to direct lightning strikes.
|
High
|
Appropriate grounding practices must be closely followed.
|
Commercial building contains a mix of information technology equipment and industrial equipment, such as welding.
|
Medium to high
|
Appropriate grounding practices must be closely followed.
|
Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.
|
Medium
|
Appropriate grounding practices must be closely followed. Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the victim equipment.
|
New commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.
|
Low
|
Appropriate grounding practices should be followed as closely as possible. Electromagnetic noise problems are not anticipated, but installing a best practice grounding system in a new building is often the least expensive route and the best way to plan for the future.
|
Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.
|
Low
|
Appropriate grounding practices should be followed as much as possible. Electromagnetic noise problems are not anticipated, but installing a best practice grounding system is always recommended.
|
Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or local laws and regulations.
Note Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. 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 protect the board from ESD. Always wear an ESD grounding strap when handling modules.
Follow these guidelines for preventing ESD damage:
•Always wear an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All MDS 9500 series chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. Cisco recommends that you use a personal ESD grounding strap equipped with a banana plug.
•If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.
Note This system ground is also referred to as the network equipment building system (NEBS) ground.
•If your chassis does not have the system ground attached, you must install the system ground lug. For installation instructions and location of the chassis system ground pads, see "Establishing the System Ground" section.
Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Step 1 Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.
Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. Cisco recommends that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.
Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (see Figure 2-10):
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.
Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.
b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

c. In addition, follow these guidelines when handling modules:
–Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
–Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
–Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety reasons, check the resistance value of the antistatic strap periodically. The measurement should be between 1 and 10 megohm (Mohm).
Establishing the System Ground
This section describes how to connect a system ground to the MDS 9500 series switches.
Note This system ground is also referred to as the network equipment building system (NEBS) ground.
You must use the system (NEBS) ground on both AC- and DC-powered systems if you are installing this equipment in a U.S. or European Central Office.
The system (NEBS) ground provides additional grounding for EMI shielding requirements and grounding for the low voltage supplies (DC-DC converters) on the modules and is intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:
•You must install the system (NEBS) ground connection with any other rack or system power ground connections that you make. The system ground connection is required if this equipment is installed in a U.S. or European Central Office.
•You must connect both the system (NEBS) ground connection and the power supply ground connection to an earth ground. The system (NEBS) ground connection is required if this equipment is installed in a U.S. or European Central Office.
•For MDS 9500 series chassis that are equipped with DC-input power supplies, you must install the system (NEBS) ground before you attach the source DC power cables to the DC PEM. If the chassis is powered up, you must power down the chassis before attaching the system (NEBS) ground. If you are installing the system (NEBS) ground on models of the MDS 9500 series chassis that are equipped with either AC-input or DC-input power supplies, you do not need to power down the chassis.
Note The system (NEBS) ground serves as the primary safety ground for the MDS 9500 series chassis that are equipped with DC-input PEMs. The DC-input power supplies for these chassis do not have a separate ground.
Required Tools and Equipment
To connect the ground system, you need the following tools and materials:
•Grounding lug—A two-hole standard barrel lug. Supports up to 6 AWG wire. Supplied as part of accessory kit.
•Grounding screws—Two M4 x 8mm (metric) pan-head screws. Supplied as part of the accessory kit.
•Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. Commercially available 6 AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.
•No. 1 Phillips screwdriver.
•Crimping tool to crimp the grounding wire to the grounding lug.
•Wire-stripping tool to remove the insulation from the grounding wire.
Grounding the Chassis
This section describes how to connect the Cisco MDS 9500 Series to earth ground.
You must complete this procedure before connecting system power or powering up your shelf.
Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment. For a Cisco MDS 9509 Director with a DC power supply, a grounding cable must be connected to the terminal block. For a Cisco MDS 9506 Director with a DC power supply, the chassis ground is required.
Figure 2-13 shows the system ground location on the Cisco MDS 9509 chassis.

Caution Grounding the chassis is required for Cisco MDS 9506 Directors that have DC power supplies, and Cisco recommends grounding for all other chassis types, although the rack is already grounded. A grounding pad with two threaded M4 holes is provided on the chassis for attaching a grounding lug. The ground lug must be NRTL listed. In addition, copper conductor (wires) must be used and the copper conductor must comply with the NEC code for ampacity.
Figure 2-14 shows the system ground location on the Cisco MDS 9506 chassis.

To attach the grounding lug and cable to the chassis, follow these steps:
Step 1 Locate the ESD socket on your chassis and attach the ESD plug.
Step 2 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding cable.
Step 3 Insert the stripped end of the grounding cable into the grounding lug.
Step 4 Use the crimping tool to secure the grounding cable in the grounding lug.
Step 5 Remove the adhesive label from the grounding pad on the chassis.
Step 6 Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws with washers through the holes in the grounding lug and into the grounding pad. Ensure that the lug and cable do not interfere with other equipment.
Step 7 Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground.
Starting Up the Switch
This section provides the following information:
•Connecting the Power Supplies
•Powering Up the Switch and Verifying Component Installation
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.
Note The 2500-W (DS-CAC-2500W) power supplies provide power according to the input voltage. If they are in redundant rather than combined mode at 110 VAC, they may be unable to provide adequate power to all modules present in the system. See Appendix B, "Technical Specifications".
Connecting the Power Supplies
The Cisco MDS 9513 Director uses a 6000-W power supply. The 6000-W AC power supplies for the Cisco MDS 9513 Director are designed to provide an output power for the modules and fans. Each power supply has two AC power connections and will provide power as follows:
•One AC power connection @110 VAC = No output
•Two AC power connection @110 VAC = 2900-W output
•One AC power connection @ 220 VAC = 2900-W output
•Two AC power connection @ 220 VAC = 6000-W output
Note Power output does not include the power used by the individual modules used in the chassis.
The Cisco MDS 9509 Director and Cisco MDS 9506 Director support both AC and DC power supplies.
The Cisco MDS 9506 Director uses power entry modules (PEMs) to provide power to its power supplies, whether they are AC or DC (there is no power connector on the power supplies). The left PEM (as viewed from the front of the switch) provides power to the upper power supply in the back of the Cisco MDS 9506 Director, and the right PEM provides power to the lower power supply.
This section provides the following topics:
•Providing Power to an AC Power Supply for the Cisco MDS 9513 Director
•Providing Power to an AC Power Supply for the Cisco MDS 9509 and Cisco MDS 9506 Directors
•Providing Power to a DC Power Supply in the Cisco MDS 9509 Director
•Providing Power to a DC Power Supply in the Cisco MDS 9506 Director
Providing Power to an AC Power Supply for the Cisco MDS 9513 Director
To provide power to an AC power supply in a Cisco MDS 9513 Director, follow these steps:
Step 1 Plug the power cable into the power supply, and tighten the screw on the cable retention device to ensure that the cable cannot be pulled out. Each power supply has two AC power connections (as shown in Figure 2-15).

Step 2 Connect the other end of the power cable to an AC power source.
Step 3 Turn the power switch to the on (|) position on the power supply.
Step 4 Verify power supply operation by checking that the power supply LEDs are in the following states:
•INPUT OK LEDs are green.
•FAN OK LEDs are green.
•OUTPUT FAIL LED is off.
See Table 1-2 on page 1-11 for power supply LED details.
Providing Power to an AC Power Supply for the Cisco MDS 9509 and Cisco MDS 9506 Directors
The basic procedure for providing power to an AC power supply is the same for both a Cisco MDS 9509 Director and a Cisco MDS 9506 Director.
Figure 2-16 shows a 2500-W AC power supply for the Cisco MDS 9509 Director.
