Replacing Network Processor Modules
Replacing Network Processor Modules
Follow these steps to replace 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 it lightly against the chassis wall. (See
Figure 5-4.)
Step 2
Gently, without bending the connector pins, push the network processor module into place,
inserting the male network processor module connector into the female network processor
module connector on the motherboard.
Step 3
Replace the module mounting screw on the end of the network processor module. (See
Figure 5-4.)
Step 4
If the module has external rear mounting screws to attach the network processor module to
the rear of the chassis, replace the screws at this time.
Caution
Do not overtorque the module mounting screw. The network processor module or the
underlying motherboard could be damaged. The maximum screw torque is 7 inch-lb.
Replacing the Component Tray
Follow these steps to replace the component tray in the chassis shell:
Step 1
Reinsert the component tray into the shell, pushing on the back of the tray, while at the same
time pressing on the chassis release screw (as shown in Figure 5-1) with the thumb of your
right hand.
Step 2
Retighten the chassis release screw.
Testing Your Installation
Test your installation by rebooting the system. When you power up a system in which one or more
of the boot ROMs was incorrectly inserted, the system will not boot into the ROM monitor or the
operating system mode.
If you suspect that your boot ROMs were inserted incorrectly, reopen the chassis, locate the affected
boot ROM and remove it, straighten its pins, reinsert the boot ROM, and try booting again.
