Replacing a Cable Kit in a Sun Fire V20z Server

Follow these steps to remove and replace the following cables (refer to FIGURE 2):

■Five-pin cable connecting the SCSI backplane to the motherboard (1).

■68-pin ribbon cable connecting the SCSI backplane to the motherboard (2).

■Flat cable connecting the SCSI backplane to the motherboard (3).

■Flat cable connecting the CD-ROM/DVD to the motherboard (5).

■Flat cable connecting the Diskette Drive to the motherboard (6).

■Flat cable connecting the operator panel board to the motherboard (7).

1. Turn off the system, including any attached peripherals.

Refer to the Sun Fire V20z and Sun Fire V40z Servers User Guide for full instructions

on powering off the server.

2. While pressing the cover latch release button with your right thumb (A), slide the

cover towards the rear of the chassis until it contacts the stop (B).

4. Identify the cable to be replaced.

FIGURE 2 Sun Fire V20z System Cables

The two halves of the 5-pin SCSI backplane power cable connector (1) are secured

with a hook.

The 68-pin SCSI ribbon cable (2) has no locking mechanism.

The small flat cables (3-7) are attached using two different types of zero insertion

force (ZIF) cable connectors. Because of their small size, it may be difficult to

distinguish one connector type from the other.

Refer to FIGURE 3 for the methods used to release cables from the various types of

connectors.

Caution – Use caution when removing cables as they are fragile—the small flat

flexible cables and cable connectors are extremely sensitive.

5. Check the routing of all cables for obstructions before reinstalling the cover.
