Network Processing Engine Replacement Instructions 29

Reconnecting Input Power and Powering Up the Router

Step 8 If you removed power supplies from the router, replace the power supplies. (See the

“Removing and Replacing an AC-Input or DC-Input Power Supply” section on page 35

when replacing a power supply in a Cisco 7200 series router.)

Step 9 If you slid the front of the router out of the rack, slowly guide the router back into the rack.

Step 10 Use a 3/16-inch ﬂat-blade screwdriver to tighten the 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 If you are using an NPE-100 or NPE-150, make sure you replace the boot ROM on the I/O

controller before attempting to boot your router. See the “Software and Hardware Requirements”

section on page 12 for network processing engine installation requirements.

This note does not apply to a Cisco uBR7200 series router or to the Cisco AS5800 Universal Access

Server router shelf.

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

(O) 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 the

Cisco 7200 series routers, see Figure 19. For the Cisco uBR7200 series routers, see

Figure 20.)
