Memory Replacement Instructions for the Network Processing Engine and Input/Output Controller 45
Reconnecting Input Power and Powering Up the Router
Note The network processing engine is not fully seated in the router midplane until you
tighten its captive installation screws.
Step 7 If you removed power supplies from the router, replace the power supplies. (Refer to the
“Removing and Replacing an AC-Input or DC-Input Power Supply” section on page 58
when replacing an AC-input or DC-input power supply in a Cisco 7200 series router.)
Step 8 If you pushed the front of the router out of the rack, slowly guide the router back into the
rack.
Step 9 Use a 3/16-inch flat-blade screwdriver to tighten the four screws that secure the router to
the front mounting strips of the rack.
This completes the procedure for replacing the network processing engine in a Cisco 7200 series
router or Cisco uBR7200 series router.
Reconnecting Input Power and Powering Up the Router
The following procedures explain how to reconnect input power to a Cisco 7200 series router or
Cisco uBR7200 series router, power up the router, and verify a successful system boot.
Warning Read the installation instructions before you connect the system to its power source.
Note Make sure you replace the boot ROM on the I/O controller before attempting to boot a
Cisco 7200 series router that has a newly installed NPE-100 or NPE-150. Refer to the “Software and
Hardware Requirements” section on page 13 for network processing engine installation
requirements.
This note does not apply to Cisco uBR7200 series routers or to the Cisco 7206 and Cisco 7206VXR
as router shelves in a Cisco AS5800 Universal Access Server.
If you have a DC-input power supply installed in your router, proceed to the “Reconnecting
DC-Input Power” section on page 47; otherwise, proceed to the next section “Reconnecting
AC-Input Power.”
Reconnecting AC-Input Power
To reconnect AC-input power to a Cisco 7200 series router or Cisco uBR7200 series router,
complete the following steps:
Step 1 At the rear of the router, check that the power switch on the power supply is in the OFF
(0) position.
Step 2 Slide the cable-retention clip up (Cisco 7200 series) or to the left (Cisco uBR7200 series),
away from the AC receptacle, and plug in the power cable.
Step 3 Secure the cable in the power supply AC receptacle by sliding the cable-retention clip
down (Cisco 7200 series) or to the right (Cisco uBR7200 series) until it snaps around the
connector. The cable-retention clip provides strain relief for the AC power cable. (For a
Cisco 7200 series router, see Figure 37. For a Cisco uBR7200 series router, see
Figure 38.)
