Removing the Network Processing Engine
Step 1 Facing the rear of the router, place the power switch on the power supply in the off (O) position. Repeat
this action if a second power supply is installed in the router.
Note When powering off the router, wait a minimum of 30 seconds before powering it on again.
Step 2 Observe the following items:
• The green OK LED on the power supply turns off.
• The fans stop operating.
• The LEDs on the I/O controller turn off.
• The LEDs on the port adapters turn off.
Caution When the power switch on a Cisco uBR7200 series power supply is turned to the off (O) position, the
power supply enters a reset cycle for 90 seconds. Wait at least 90 seconds before turning the power
switch back to the on (|) position. If you do not wait the full 90 seconds, the power supply does not
restart.
This completes the procedure for powering down the router. The following sections provide instructions
on disconnecting power from the Cisco 7200 VXR routers and Cisco uBR7200 routers:
