Removing and Replacing the Network Processing Engine
Powering Down the Router
To power down a Cisco 7200 series router or Cisco uBR7200 series router, complete the following
steps:
Note Before powering down the router, use the copy running-config startup-config command to
save the router’s running configuration to nonvolatile memory.
Step 1 Facing the rear of the router, place the power switch on the power supply in the OFF (0)
position. Repeat this action if a second power supply is installed in the router.
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.
• On a Cisco uBR7200 series router, the LEDs on the cable modem cards turn off.
This completes the procedure for powering down a Cisco 7200 series router or Cisco uBR7200
series router.
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.
Disconnecting AC-Input Power
To disconnect AC-input power to a Cisco 7200 series router or Cisco uBR7200 series router,
complete the following steps:
Step 1 Unplug the input power cable from the power source.
Step 2 On a Cisco 7200 series router, push up on the cable-retention clip that secures the input
power cable to the router’s power supply.
On a Cisco uBR7200 series router, push the cable-retention clip to the left.
Step 3 Unplug the other end of the input power cable from the power supply. (For the Cisco 7200
series routers, see Figure 10. For the Cisco uBR7200 series routers, see Figure 11.)
