Intel II manual Installing a 5.25-inch Peripheral Device, Remove Filler Panels and EMI Shields

Installing a 5.25-inch Peripheral Device

Two 5.25-inch half-height bays provide space for tape backup, CD-ROM, or other removable media drives.

CAUTION

For several reasons, we recommend that you do NOT install hard drives in the 5.25-inch bays: the drives cannot be properly cooled in this location; a hard drive generates EMI and is more susceptible to ESD in this location.

✏NOTES

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.

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 may not work at all. The SCSI bus needs to be terminated at the end of the cable, and this is usually provided by the last SCSI device on the cable.

1.Observe the safety and ESD precautions at the beginning of this chapter.

2.Remove the side and front system covers. Place the front cover on a flat surface.

3.Remove filler panel from the bay and set it aside.

4.￿Push the tab on the left side of the EMI metal shield to the right to disengage it from the chassis. Save the shield.
