The Ultra320 DE100 drive carrier contains one (1) front-mounted drive car-
rier fan for enhanced heat dissipation. Should the fan ever fail, the unit ID
number indicator (located on the front of the receiving frame) will display a
flashing “F” (refer to figure below) and an audible alarm will sound.
In case of failure, the fan is easily field-replaceable. Refer to the full
version of the DE100 Ultra320 SCA User’s Guide for further information.

For SCSI Ultra320 operation, the DE100 Ultra320 SCA requires Ultra320
drives, Ultra320 HBA, and Ultra320-compliant cabling (internal and external).
DE100 Ultra320 SCA can support Ultra320 implementations with a maximum of fifteen
(15) Ultra320 drives (Ultra320 repeater may be required).
