RAID Array 3000 Expansion Pedestal
4–6
EK–SMCPO–UG. A01
The RAID Array 3000 base pedestal is factory-configured for split-bus operation.
You must reconfigure the bus in the base subsystem from split-bus to a “through-
bus” configuration prior to connecting the expansion cabinet to the base subsys-
tem. The components needed to reconfigure the split-bus in the base subsystem
are included with your pedestal expansion kit option.
CAUTION
To prevent electrostatic discharge (ESD) from
damaging the controller, always wear an ESD wrist
strap connected to a suitable ground whenever you
handle any of the electronic components.
Perform the following procedure to reconfigure the SCSI bus in the base pedestal
from a “split-bus” to a “through-bus” configuration:
1.
Perform an inventory of the bus conversion items supplied with the pedestal
expansion kit option. The items should consist of:
•
SCSI bus jumper cable 17-04166-03
•
SCSI cable 17-04454-01
2.
Quiesce the host bus by shutting down the host system.
CAUTION
To allow the UPS to supply power while the cache
is being flushed to disk, do not unplug the base
pedestal from the UPS.
3.
Unplug the base power cord from the wall outlet.
4.
Unplug the UPS power cord from the wall outlet, the UPS will now signal
the controller to flush the cache.
5.
Wait until the UPS shuts down completely (this may take several minutes).
6.
Power off the base pedestal and plug the UPS into the wall outlet.
7.
Remove the side cover from the base pedestal (Figure 4–5).
