8-15A18 REAR PANEL PCB This paragraph provides instructions for removing and replacing the

A18 Rear Panel PCB assembly.

Equipment Required:

￿Nut Driver, 932 in.

￿Nut Driver, 316 in.

Preliminary:

￿Switch373XXA power off. Remove the power cord.

￿Remove all covers (paragraph 8-3).

￿Remove Rear Panel (paragraph 8-12).

Remove/Replace Procedure:

Step 1. Place the Rear Panel Assembly on the work surface with the A18 Rear Panel PCB up.

Step 2. Disconnect the two-conductor fan power cable at connector

P6 of the A18 PCB.

Step 3. Disconnect the wiring for the rear panel Bias Fuses at con- nector P4 of the A18 PCB.

Step 4. Turn Rear Panel Assembly over. Remove screw located at lower left corner of the rear panel that fastens the A18 PCB to the Rear Panel Assembly (see Figure 8-10).

Step 5. Using a 932 in. nut driver, remove the standoffs that fasten the IEEE 488.2 GPIB and Dedicated GPIB connectors to the rear panel.

Step 6. Using a 316 in. nut driver, remove the standoffs that fasten the Printer Out, VGA Out, and External/IO connectors to the rear panel. Set standoffs aside for re-use.

Step 7. Carefully separate the A18 PCB from the rear panel.
