Figure B-3: 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 DE75i-SW receiving frame as shown in Figure B-3. 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 drive to spin down is approximately 15 seconds or more. This number can vary
depending on the type of SCSI device and manufacturer (some drives may require
45 seconds or more). The factory configuration is set for 20 seconds. A different
delay time may be selected with the provided alignment tool. Refer to the SCSI
device manufacturer’s manual for more information on required device spin down
time.
Carrier Installation
Follow the procedures below to install the DE75i-SW Carrier into the receiving frame equipped
with the Hot Swap option.
1. Install the carrier into the receiving frame. A "u" will be present on the front panel,
indicating that the carrier is in an unlocked condition.
2. Turn the key lock mechanism, located on the front of the receiving frame, counter
clockwise to the ON position. This locks the drive into the receiving frame and activates
the Hot Swap Board. The drive will begin to spin up and the unit number on the display
will begin flashing.
3. After a short length of time the unit display will stop flashing, indicating that the device
is ready to be used.
