1.2.2 Drive Trays

The subsystems come with 12 or 8 drive trays (see Figure 1-14) designed to

accommodate separately purchased standard 1-inch pitch, 3.5-inch disk drives. The

drive bays are accessed from the enclosure front. Two LED’s on the front of the tray

are used to indicate the drive status. A key-lock on each drive tray secures the hard

drive in place, while an easily accessible release button ensures fast and efficient

drive hot-swapping.

WARNING!

Be careful not to warp, twist, or contort the drive tray in any way (e.g., by dropping it

or resting heavy objects on it). The drive tray has been customized to fit into the drive

bays in the subsystem. If the drive bay superstructure is deformed or altered, the drive

trays may not fit into the drive bay.
