Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

• Locate the room's emergency power-OFF switch. Then, if an electrical accident occurs, you can quickly shut the power OFF.
  
  
• Before working on the system, turn OFF the power and unplug the power cord.
  
  
• Disconnect all power before doing the following:
  
  
• • Working on or near power supplies
    
    
  • Installing or removing a router chassis or network processor module
    
    
  • Performing a hardware upgrade
    
    
• 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

Overview of Cisco 2600 Series Power Supplies

Figure 1 shows the typical AC power supply for Cisco 2600 series routers. The DC power supplies look similar, but have a terminal block cover in place of the three-pronged connector for an AC power cord.

Figure 2 shows the location of the power supply in a Cisco 2600 series router. In this case an AC power supply is shown as an example.

Table 1 lists AC power supply specifications, and Table 2 lists DC power supply specifications. These tables apply to all Cisco 2600 series routers.

Tools and Equipment Required

You need the following tools and equipment to remove and install power supplies in Cisco 2600 series routers:

• Number 1 Phillips screwdriver
  
  
• Wire cutters to cut cable tie-wraps
  
  
• ESD-preventive wrist strap
  
  

Removing the Cover

To gain access to the power supply of Cisco 2600 series routers, you must first remove the chassis cover.

Follow this procedure to 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:

If you have a DC-powered router, follow these steps to remove the power cables:

Step 4   If the router is rack- or wall-mounted, remove it from the rack or wall.

Step 5   Place the router so that the front panel is facing you. Remove the screws located on top of the cover near the front edge.

Step 6   Slide the cover away from you until the metal tabs on the side edges separate from the chassis bottom, as shown in Figure 3.

Step 7   Lift the front edge of the cover until it clears the front of the chassis, as shown in Figure 4.

Removing the Power Supply

This section describes how to remove the internal power supply. Although the AC power supply is shown in the illustrations that follow, the procedure is the same for removing both the AC and DC power supplies.

Take these steps to remove the power supply:

Step 1   Locate the six-pin connector on the system board near the front of the router, and disconnect it. (See Figure 5.)

Step 2   Remove the mounting screw that secures the power supply to the chassis. (See Figure 6.) Set aside this screw for later use.

Step 3   Slide the power supply forward slightly in the chassis. This disengages the built-in hooks that help secure the power supply to the chassis. (See Figure 7.)

Step 4   Lift the power supply out of the chassis.

Installing the Power Supply

Follow these steps to install a power supply in the chassis:

Step 1   Place the power supply in the chassis, with the power supply faceplate slightly separated from the chassis rear panel. This position allows the hooks in the chassis to engage the cutouts in the bottom of the power supply. (See Figure 7.)

Step 2   Slide the power supply toward the rear of the chassis, engaging the hooks in the chassis.

Step 3   Replace the external rear mounting screw. (See Figure 6.)

Step 4   Insert the large power connector into the receptacle on the motherboard. (See Figure 5.)

Step 5   Using tie-wraps, fasten the power cables into a bundle that clears the edge of the chassis and keeps the cables away from the fan. Be sure that cables to the fans are routed under the hook in the bottom of the chassis.

Replacing the 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.

Step 3   Lower the front of the cover onto the chassis, making sure that the cover side tabs fit under the chassis side panels.

Step 4   Slide the cover toward the front, making sure that the cover tabs fit under the chassis back panel, and the back panel tabs fit under the cover.

Step 5   Fasten the cover with the screws you set aside earlier.

Step 6   Reinstall the chassis on a rack, wall, desktop, or table.

Step 7   Reinstall network interface cables.

Replacing Connections to the Router

Follow these steps to make final connections to the router:

Step 1   Replace all network connections.

Step 2   If you have an AC-powered router: plug the power cord into a 3-terminal, single-phase power source that provides power within the acceptable range (100 to 240 VAC, 50 to 60 Hz).

If you have a DC-powered router:

Step 3   Turn ON the power switch. (The power LED on the front panel of the router should go on.)

Step 4   Verify that the OK LED on the right side of the front panel goes on after a few seconds' delay when booting. If you have problems, see the next section, "Troubleshooting," and the section ""Obtaining Technical Assistance"".

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.
