RAID Array 3000 Pedestal Enclosure
3–14
EK–SMCPO–UG. A01
The SCSI bus configuration switch selects the eight (0 – 7) SCSI bus configura-
tions in the pedestal. Each bus configuration determines the slot device addresses
(0 – 6) for both 8-bit and 16-bit devices. The pedestal is configured at the factory
for split-bus operation (configuration switch set to “6”). To change the configu-
ration of the bus, you must remove the left side panel to gain access to the back-
plane and the configuration switch.
NOTE
SCSI device addresses 6 and 7 are reserved for
the RAID Array controllers. The top controller slot
in the pedestal is assigned device address 7 and
the bottom slot (redundant controller) is device ad-
dress 6. The controller allows a maximum of 15 (or
14 with dual controllers) disk devices on each of its
device buses.
To remove the side panel, proceed as follows:
1. 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.
2. Unplug the base pedestal power cord from the wall outlet.
3. Unplug the UPS power cord from the wall outlet, the UPS will now signal
the controller to flush the cache.
4. Wait until the UPS shuts down completely (this may take several minutes).
5. Power off the base pedestal and plug the UPS power cord into the wall out-
let.
6. Disconnect the SCSI cable from the host connector on the rear panel.
7. Remove the front door on the pedestal.
8. Remove the cover screw from the left side panel (see Figure 3–8).
9. Grasp the handhold at the rear of the panel and pull the panel toward the rear
and clear of the cabinet.
