press and hold the two mounting tabs and slide the device out of the pedestal. 5.25-inch
SBBs require three pedestal slots for mounting. There are guides that mate with the
grooves in the pedestal to ensure that the connector at the rear properly mates with the
pedestal connector. The insertion and removal of the 5.25-inch SBB is the same as the
3.5-inch device described above. The 5.25-inch SBB contains a switchbank at the rear of
the unit to set the SCSI address of the device manually. If not used, the SCSI address is
set automatically to the pedestal's slot number.
1.3.2 Blower Unit
The StorageWorks Wide Expansion Storage Pedestal contains two dual-speed blowers
for cooling purposes. The blowers are mounted at the rear of the pedestal and obtain their
power through a connector on the backplane. The blowers are secured by two "press-to-
release" mounting tabs and a single screw in the corner of each blower unit. The blowers
normally run at the lower speed. If one of the blowers fails, the second blower
automatically goes to the higher speed. An LED on the front of the personality module
goes out, indicating the failure of one blower. This dual-speed operation prevents
overheating of the storage device.
