–Performing most hardware upgrades
•Do not work alone if potentially hazardous conditions exist.
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.
•Never assume that power is disconnected from a circuit. Always check.
•If an electrical accident occurs, proceed as follows:
–Use caution, and do not become a victim yourself.
–Turn off power to the system.
–If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms).

•Removing the Router Cover
•Removing the Cisco 3620 and Cisco 3640 Power Supplies
•Installing the Cisco 3620 and Cisco 3640 Power Supplies
•Replacing the Router Cover
Removing the Router Cover
To gain access to the Cisco 3620 or Cisco 3640 power supply, you must first remove the chassis cover:
Step 1 Turn off power to the router.
Step 2 Remove all network interface cables from the rear panel.
Step 3 If you have an AC-powered router, remove the power cord.
The following warnings apply to routers with DC power supplies:
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Warning When installing the unit, always make the ground connection first and disconnect it last. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
If you have a DC-powered router, follow these steps to remove the power cables:
a. Use a screwdriver to loosen the captive installation screws on the terminal block cover.
b. Lift and remove the terminal block cover.
c. Use a screwdriver to remove the three power leads from the terminal block, in this order: negative, positive, then ground.
Step 4 If the router is rack- or wall-mounted, remove it from the rack or wall.
Step 5 Place the router so the front panel is closest to you. Remove the three screws located on top of the cover near the front edge. (See Figure 7 and Figure 8.) Set the screws aside in a safe place.
Step 6 Lift the front edge of the cover about 1 inch (2.5 cm) above the chassis, as shown in Figure 9.
Step 7 Pull the cover toward you until the metal tabs on the rear edge separate from the chassis bottom. (See Figure 7 and Figure 8.)

Replacing the Router Cover
After you finish replacing the power supply, follow these steps to replace the cover:
Step 1 Place the chassis bottom so the front panel is closest to you.
Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom, as shown in Figure 20 and Figure 21.
Step 3 Push the cover toward the rear, making sure that the cover tabs fit under the chassis back panel, and the back panel tabs fit under the cover.
Figure 20 Replacing the Cisco 3620 Cover
Figure 21 Replacing the Cisco 3640 Cover
Step 4 Lower the front of the cover onto the chassis, making sure that the cover side tabs fit under the chassis side panels, and the chassis tabs fit under the cover side panels.
Step 5 Fasten the cover with the three screws you set aside earlier.
Step 6 Reinstall the chassis on a rack, wall, desktop, or table.
Step 7 Reinstall network interface cables.
Step 8 Proceed to the "Electrical Connections for Cisco 3600 Series Routers" section.
Hot Swapping the Cisco 3660 Power Supply
The Cisco 3660 accommodates two AC or two DC hot-swappable power supplies (PS1 and PS2) in bays at the rear of the unit (see Figure 6). Each unit provides up to 250W of power, and a single installed power supply meets the router's requirements. The second installed power supply provides redundancy, load sharing, and increased system availability. It can be removed without affecting system operation.
Removing the Cisco 3660 Power Supply
To remove a power supply, use the following procedure:
Step 1 Identify the failed power supply by checking the power supply LEDs (PS1 and PS2) on the router's front panel.
Step 2 Facing the rear panel, identify the failed power supply by checking the bay (PS1 or PS2) that it is installed in, and checking that the LED on the power supply is orange or off. (See Figure 22 for the location of the power supply LED.)
Step 3 Turn off power to the failed power supply and unplug the power cable.
Note Always unplug the power cable before loosening the captive screws. If the power cable is still plugged in it prevents the captive screws from being loosened adequately to remove the power supply.
Step 4 Loosen the two captive screws holding the power supply in the chassis bay, using the Phillips or flat-blade screwdriver. (See Figure 22.)
Step 5 Slide the power supply out of the bay.
Figure 22 Hot Swapping a Cisco 3660 Router Power Supply
Installing the Cisco 3660 Power Supply
To install a power supply, use the following procedure:
Step 1 Check that the power switch on the power supply is in the OFF position.
Step 2 Align the power supply with the chassis bay, and slide it in until the center hole (between the captive screws) is aligned with the hole in the bay's lower shelf. (See Figure 22.)
Step 3 Tighten the two captive screws that secure the power supply in the chassis bay, using the Phillips or flat-blade screwdriver.
Step 4 Connect the power cord to the replacement power supply.
Note The power cord connector can be inserted in the power socket only when the captive screws are tightened. This prevents hot swapping of live power supplies.
Step 5 If you are replacing a power supply, continue with Step 6 of this sequence; if you are installing a power supply for the first time, proceed to the "Electrical Connections for Cisco 3600 Series Routers" section.
Step 6 Turn on power to the replacement power supply.
Step 7 Check that the LED on the power supply is green. (See Figure 22 for the location of the power supply LED.)
Step 8 Check that the corresponding power supply LED (PS1 or PS2) on the front panel is green.

Step 3 Plug the connector and power cable into the power receptacle on the power supply.
Step 4 Secure the wires to the wire management bracket. Use a cable tie through one of the holes in the wire management bracket. Make sure that the service loop does not extend above or below the power supply. (See Figure 26.)
Caution Power wires must exit to the right, and the service loop must not extend above or below the power supply.

Caution To avoid damaging the power supply if you have to return the chassis to the manufacturer (for example, if a failure occurs), remove the power cable so that the chassis fits in the shipping container.
Powering On the Router
Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Caution Never operate the router unless the unit is completely closed to ensure adequate cooling.
To power on the router, take the following steps:
Step 1 For routers with AC input, plug the router's power cord into a three-terminal, single-phase power source that provides power within the acceptable range.
Warning This product relies on the building's installation or power supply for short circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker no larger than 60 VDC, 15A U.S. is used on all current-carrying conductors. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Step 2 Power on the router. The LED labeled SYSTEM on the front panel should come on.
Note If you encounter problems when you power on the router, see the "Troubleshooting" section that follows.
Troubleshooting
Check the following items to help isolate problems with the power supply installation:
•With the power switch on, is the power LED on the front panel on?
–If not, check the AC or DC input, AC or DC source, router circuit breaker, and the power supply cable (AC) or power supply wiring (DC).
–Check the power supply connection to the motherboard.
–If the power LED is still off, the problem might be a power supply failure.
•Does the router shut down after being on a short time?
–Check the fans. If the fans are not working, the router will overheat and shut itself down.
–If the fans are not working, check the power supply connections to the fans.
–Ensure that the chassis intake and exhaust vents are clear.
–Check the environmental site requirements in your router installation and configuration guide.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.
Cisco TAC Web Site
The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
