Removing the Network Processing Engine
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
