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:
(a) Use a screwdriver to loosen the captive installation screws on the terminal block
cover.
(b) Lift and remove the terminal block cover.
Warning Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units.
Warning Do not touch the power supply when the power cord is connected. For systems
with a power switch, line voltages are present within the power supply even when the
power switch is off and the power cord is connected. For systems without a power switch,
line voltages are present within the power supply when the power cord is connected.
Warning Do not work on the system or connect or disconnect cables during periods of
lightning activity.
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.
Warning When installing the unit, the ground connection must always be made first and
disconnected last.
