6 FC unit address switch
When you connect more than one Fibre Channel
Storage Units, you need to specify a unique address (0
to 11) for each unit.
To set the address of a Fibre Channel Storage Unit,
insert a rod or narrow screwdriver into the one of the
holes at the left and right of the address displayed on
the FC unit address switch, and press the switch inside
the hole. Pressing the right-side switch increments the
address, and pressing the left-side switch decrements
the address.
Note
Always power the Fibre Channel Storage Unit off
before changing its address.
7 Fan check indicator (yellow)
Lights when a fan is faulty.
8 Drive fan pack
This is a fan unit integrated into the Fibre Channel
Storage Unit. One drive fan pack contains three fans.
The fan check indicator on the fan pack lights
whenever any of the fans is faulty. Remove the drive
fan pack before powering the Fibre Channel Storage
Unit on or off.
Note
You can remove the drive fan pack without powering
the Fibre Channel Storage Unit off. When you remove
the drive fan pack, the cooling check indicator begins
to flash. If the drive fan pack is removed for more than
two minutes, power to the hard disk drives is cut
automatically. (The Fibre Channel Storage Unit itself
remains powered on.) The hard disk drives are
powered on again when you replace the drive fan pack.
9 AC power connector
Connect to an AC power source with the specified AC
power cord.
Caution
Always use the specified AC power cord. Use of
