Ensuring Easy Access to the Router
If your Cisco 7200 VXR or Cisco uBR7246VXR router is installed in a standard 19-inch, 4-post or
telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router.
Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the
following guidelines to ensure easy access to the rear of the router when it is installed in a rack. This is
particularly important because the NPE-G1 and NPE-G2 have interfaces that require cabling on the rear
of the router.
Note The NPE-G2 is not supported on the Cisco uBR7246VXR router.
If the router is not installed in a rack, or if you already have clear access to the rear of the router, proceed
to the “Powering Down the Router and Disconnecting Input Power” section on page 7-8.
Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:
• Ensure that you have at least 3 to 4 feet (0.91 to 1.22 meters) of working space at the rear of the
router.
• If cables from other equipment in the rack fall in front of the rear end of the router, carefully gather
the cables (using care not to strain or stress them) and use cable ties to anchor them away from the
rear of the router.
• If access to the rear of the router is partially blocked by a power strip or some other permanent rack
fixture, detach the router from the rack and carefully slide it forward until there is enough clearance
to remove the power supply, the network processing engine, and the subchassis from the router.
Caution Make sure that at least one other person is available to support the front of the router as you slide it out
from the rack and, if necessary, to continue to support it while you remove and insert the power supply,
network processing engine, or subchassis.
Powering Down the Router and Disconnecting Input Power
Complete the steps in the following sections to power down the router and disconnect input power.
Caution This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two
power cords before servicing. Statement 83
Powering Down the Router
To power down a Cisco 7200 VXR or Cisco uBR7246VXR 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 a Flash Disk, PC Card, or TFTP server. If you do not, you will have to
manually reenter the configuration after you install the NPE-G1 or NPE-G2 and power on the router. See
the “Copying the Configuration File” section on page 7-4.
