About the Rackmount Disk-Array Processor Enclosure

Figure 1-12 Drive Fan Pack

The drive fan pack has one status light. The status light is described

in the “Monitoring DPE Status” section of Chapter 3.

Latches on the drive fan pack hold the pack in place.

You can remove the drive fan pack while the DPE is powered up. While the

pack is removed, the cooling check light on each power supply flashes. If the

pack is removed for more than approximately two minutes, the disk modules

and SPs power down. The disk modules and SPs power up when you

reinstall the drive fan pack.

SP Fan Pack The SP fan pack (see Figure 1-12) cools the SPs. It contains three fans

that draw ambient room air through the SP fan pack cover, through

the midplane, and across the SPs. The SP fan pack connects to the

DPE midplane via an internal cable, and either supply can power it.

The fans operate at a lower voltage and speed during normal

operation to minimize acoustic noise. If a fan fails, the voltage and

speed of the remaining fans increase to compensate, resulting in

higher acoustic noise.
