Memory Replacement Instructions for the Network Processing Engine and Input/Output Controller 43

Replacing the Network Processing Engine

Step 8 Replace Flash Disks or Flash memory cards (if present) in the I/O controller’s PC card

slots. (Refer to the “Installing and Removing a Flash Memory Card” section on page 52.)

This completes the procedure for replacing the I/O controller in a Cisco 7200 series router or

Cisco uBR7200 series router.

Replacing the Network Processing Engine

To replace the network processing engine in the router, complete the following steps:

Note The NPE-300 is only compatible with the Cisco 7200 VXR routers; it is keyed to prevent

insertion in Cisco 7200 routers (7202, 7204, and 7206).

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.

Step 1 Ensure that the router is powered down and its input power cable is disconnected from

the router and the power source. Refer to the “Powering Down the Router and

Disconnecting Input Power” section on page 21.

Step 2 Attach an ESD-preventive wrist strap between you and an unﬁnished chassis surface.

Step 3 Using both hands, grasp the network processing engine by its metal carrier edges and

orient the network processing engine so that its printed circuit board components are

upward (you can see the components). (See Figure 10.)

Caution Handle the network processing engine by the carrier edges and handle only; never touch

the printed circuit board components or connector pins.

Step 4 Align the left and right edge of the network processing engine’s printed circuit board

between the network processing engine slot guides. (For a Cisco 7200 series router, see

Figure 35. For a Cisco uBR7200 series router, see Figure 36.)

Note The NPE-300 carrier has metal posts that slide into grooves cut into the

Cisco 7200 VXR network processing engine slot. This keying feature does not alter the

installation procedure for the NPE-300. (See Figure 7.)
