Remove/Replace the Front Panel

1

Remove the top cover. (See Figure 12 on page 42.)

2

Disconnect the front panel connector from the mother board by pressing
down on the two latches on the end of the connector on the mother board
and lifting the connector straight up. (See Figure 13.)

WA RN I N G

This procedure is intended for use by Agilent-trained service personnel only. There
are no user-serviceable parts inside the 35900.

C A U T I O N

The printed circuit (PC) boards in the 35900 can be damaged by electrostatic discharge.
Do not touch any of the boards unless it is absolutely necessary. If you must handle
them, wear a grounded wrist strap and take other antistatic precautions. Wear a
grounded wrist strap any time you must remove the 35900 top cover.
