3.4. Starting the Drives
Unless otherwise selected during installation, all drives in the enclo-
sure should automatically start their motors. If this has not occurred
one of the following conditions may exist:
✦
There may be a power problem (an alarm and power fault
indication would normally be active).
✦
If there is only one PSU present, the drive motors will spin up
in a delayed sequence.
3.4.1. Disk Drive LEDs
Each Drive Carrier module incorporates two LEDs, Upper (Green)
and Lower (Amber), shown in
Fig. 10
.
✦
In normal operation the Green LED will be ON and will flicker
as the drive operates.
✦
In normal operation the Amber LED state will be:
– OFF if there is no drive present,
– OFF as the drive operates, and
– ON if there is a drive fault present.
3.4.2. Engaging the Drive Module Anti-
tamper Locks
The anti-tamper locks are fitted in the drive carrier handles and are
accessed through the small cutout in the latch section of the handle.
3.4.2.1. Activating the Locks
1. Carefully insert the lock key provided into the cutout in the
handle.
2. Locate the key into its socket.
3. Rotate the key in a clockwise direction until the indicator is vis-
ible in the aperture beside the key.
4. Remove the key. De-activation is the reverse of this procedure,
that is:
✦
Rotate the key in an anti-clockwise direction until the indicator
is no longer visible in the aperture beside the key.
NOTE:
A drive carrier cannot be installed if its anti-tamper lock is
activated outside the enclosure.
