Removing and Replacing the Network Processing Engine
Step 8 Connect the ground, +48V, and –48V leads to the power source.
Note For the Cisco 7200 series, each DC-input power supply operating at –48 VDC in
North America requires a minimum of 13A service. Each DC-input power supply
operating at –60 VDC in the European Community requires a minimum of 8A service.
For the Cisco uBR7200 series routers, each DC-input power supply rating is 14A,
700 volt ampere (VA).
This product relies on the building’s installation for short-circuit (overcurrent) protection.
Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used
on all current-carrying conductors.
Step 9 Repeat Step 1 through Step 8 if a second power supply is installed.
This completes the steps for reconnecting DC-input power to a Cisco 7200 series router or
Cisco uBR7200 series router. Proceed to the “Powering Up the Router” section on page 34.
Powering Up the Router
To power up a Cisco 7200 series router or Cisco uBR7200 series router that has an installed power
supply, complete the following steps:
Step 1 Check for the following:
• Each port adapter is inserted in its slot, and its respective port adapter lever is in the
locked position.
• The network processing engine and the I/O controller are inserted in their respective
slots, and the captive installation screws are tightened.
• All network interface cables are connected to the port adapters.
• Each cable modem card is inserted in its slot, and its respective captive installation
screws are tightened (Cisco uBR7200 series only).
• A Flash memory card or Flash Disk is installed in one of the PC Card slots.
Note The Flash Disk can be installed in either slot 0 or slot 1.
• Each AC-input power cable is connected and secured with the cable-retention clip
(AC-input power supplies only).
• For a Cisco 7200 series router, each DC lead is connected and secured to the power
supply faceplate with a cable tie; for a Cisco uBR7200 series router, each DC lead is
connected with M5 nuts for the grounding receptacle and the strain-relief cover over
the +48V and –48V leads (DC-input power supplies only).
• Each DC lead is connected and secured to the power source (DC-input power supplies
only).
• Ensure that the tape (that you applied earlier) is removed from the circuit breaker
switch handle, and power is restored by moving the circuit breaker handle to the ON
position (DC-input power supplies only).
• The console terminal is turned on.
