Disk Drive Bracket; Removing The Disk Drive Mounting Bracket - Sun Microsystems SPARCclassic Service Manual

Disk Drive Bracket

The disk drive bracket resides in the top part of the system unit in front of the power
supply (see Figure 9–13). It houses both the diskette drive and the hard disk drive.
The hard drive may be removed independently of the disk drive mounting bracket,
but you must remove the disk drive bracket before removing the diskette drive or
power supply. Refer to Figure 9–12 through Figure 9–15 for the location of the disk
drive mounting bracket and the captive screw that secures it to the system.

Removing the Disk Drive Mounting Bracket

To remove the disk drive mounting bracket:
1. Prepare to work on the system as described in Chapter 6," and in Chapter 7.
Halt the system and verify that the power LED is not lit and the fan is not
running. Then open the system unit and attach a wrist strap as described in
"Attaching the Wrist Strap" on page 53.
Caution - The AC power cord should remain attached between the system unit and
an AC wall outlet. This connection provides the ground path necessary to protect
internal system components from harmful static discharges. Inside the system unit,
be sure the power supply wiring harness is connected to the main logic board to
complete the ground.
Caution - Verify that the system power switch is in the Standby position. The green
LED at the front of the system unit should not be lit and the fan should not be
running. When the system power switch is in the Standby position, and the AC
power cord remains connected to a power outlet, hazardous AC voltage is still
present in the power supply primary. Do not attempt to service the power supply
under these conditions. Disconnect the AC power cord prior to handling the power
supply. When servicing any other system component, the AC power cord should
remain connected and poses no safety hazard.
2. Place an antistatic mat, shiny side up, next to the system unit.
3. Disconnect cables.
