6 280-Watt AC-Input Power Supply Replacement Instructions
Installation Prerequisites
• Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Ensuring Easy Access to the Router
If your Cisco 7200 series router is installed in a standard 19-inch, 4-post or telco rack, cables from
other equipment in the rack may 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. 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 following section
“Removing and Replacing the AC-Input Power Supply.”
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 three to four feet 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 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. Detailed steps for detaching the router from the rack are contained in the following
section “Removing and Replacing the AC-Input Power Supply.”
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.
