Installing Network Processor Modules

Take the following steps to install a network processor module:

Step 1 Hold the network processor module by its handle, align it with the grooves in the

chassis (not shown) and over its connector, and push the module lightly against the

chassis wall. (See Figure 3-4.)

Step 2 Push the network processor module gently into place without bending the

connector pins, inserting the male connector into the female connector on the

motherboard.
