Spin Down/Up Time
Figure 11: Device Spin Down/Up Timer
NOTE: The timer for device spin down is controlled by a small selector, located in a cutout
on the side of the DE100 receiving frame as shown in Figure 11. When the key
is turned to the OFF position, and when the timer receives a No SCSI Activity signal
from the Hot Swap Board, it waits the specified delay time before displaying a u
on the front panel of the receiving frame. The amount of time required for a disk
drive to spin down is approximately 15 seconds or more. This number can vary
depending on the type of SCSI device and manufacturer (e.g. a Seagate Barracuda
may require 45 seconds). The factory configuration is set for 20 seconds. A
different delay time may be selected with the provided aligment tool. Refer to the
SCSI device manufacturers manual for more information on required device spin
down time.
