Installing a Processor Cartridge

Use the following procedure to install a processor cartridge.

Note: All systems ship with a processor cartridge installed in the bottom slot and termination boards in the remaining slots. Some systems may have more processors, depending on configuration. All processors must be matched in speed.

1.Power off the system and remove the left side panel as described earlier.

2.Remove the clear plastic air duct covering the processors. The air duct is secured to the chassis by three pins (see Figure 4-9 A, B and C). Release the air duct pins by pulling them towards you. Set the air duct aside for later installation.
