Opening the PCB carrier

You might need to open the PCB carrier to gain access to the motherboard, expansion adapters, and other field-replaceable units in your C3100/C6100.

To open the PCB carrier, complete the following steps.

Step	Action
1	From the NetCache Manager home page, select the Maintenance tab > System Control > Halt/Reboot. Caution Always shut down your NetCache appliance properly before opening the PCB carrier. Opening the PCB carrier without first shutting down your NetCache appliance causes the system to shut down improperly. For information about shutting down the system properly, see the NetCache Appliance Administration Guide.
2	Select Halt NetCache.
3	Verify that the LCD display at the front of your NetCache appliance displays the following message: Halted
4	Turn off and unplug the power to your NetCache appliance and, if applicable, to your disk shelves.
5	Wear the antistatic wrist strap and attach the grounding leash to the NetCache appliance chassis.
6	Using a #1 or #2 Phillips screwdriver, loosen the eight thumbscrews on the back panel of the PCB carrier.
7	Carefully pull the PCB carrier out of the chassis until the carrier tabs click to lock the slide rails in place. The PCB carrier has a travel distance of approximately 19 inches (48.26 centimeters). WARNING Use caution when servicing components in the chassis. There is danger of electric shock from hazardous energy on the backplane.
