Installing a 5.25-inch Peripheral in the Front Bay
One 5.25-inch half-height bay provides space for a tape backup, CD-ROM, or other removable
media drive.
CAUTIONS
Do not install hard drives in 5.25-inch bays: We recommend that you do
NOT install hard drives in the 5.25-inch bays. The drives cannot be properly
cooled in this location; also, a hard drive generates EMI and is therefore
more susceptible to ESD in this location.
✏
NOTES
Save the filler panels and EMI shields: System EMI integrity and cooling
are both protected by having drives installed in the bays or filler panels and
EMI shields covering the bays. When you install a drive, save the panel and
shield to reinstall in case you should later remove the drive and not reinstall
one in the same bay.
Bus termination when installing SCSI devices: It is important that your
cabling and connections meet the SCSI bus specification. Otherwise, the
bus could be unreliable and data corruption could occur or devices might not
work at all. The SCSI bus needs to be terminated at the end of the cable;
this is usually provided by the last SCSI device on the cable. For more
information on connecting the data cable to a drive, see step 9 on page 127.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Remove the peripheral bay (see “Removing the Peripheral Bay” on page 117).
3. Remove the drive from its protective wrapper, and place it on an antistatic surface.
4. Record the drive model and serial numbers in your equipment log (page 197).
5. Set any jumpers or switches on the drive according to the drive manufacturer’s instructions.
6. Using two screws of the appropriate size and length (not supplied), attach each plastic slide rail
and its metal grounding plate to the drive.
