1.3.4 Pedestal Cabinet
The floor-mounted pedestal cabinet is a modular storage cabinet that is completely self-
contained with its own 3.5-inch SBB power supply, two dual-speed blowers, and two
SCSI cable connectors. Refer to Section 3.5.2 for slot assignments when two SCSI buses
are configured in one pedestal. The characteristics of the pedestal are outlined below
(refer to Figures 1–2 and 1–4).
•
The capacity of the pedestal is eight 3.5-inch SBBs, one of which must be a power
supply.
•
The pedestal slots are numbered 0 through 7 from top to bottom.
•
Seven SCSI bus device addresses (target IDs) 0 through 6, associated with the
pedestal slots, can be assigned to either 3.5-inch or 5.25-inch SBBs.
•
The slot numbers and the default SCSI device addresses are the same for slots 0
through 6. Slot 7 is reserved for the power supply and does not have a device
address.
•
There are two 68-pin, female SCSI connectors on the personality module. The
personality module plugs into the backplane directly above slot 0.
•
The ac distribution unit controls prime power (switches) to the power supply
installed in slot 7 and the optional redundant power supply in slot 6. See Figure 1–4.
•
Slot 6 can be used for either a storage SBB, a redundant power supply, or a battery
backup unit (BBU).
•
The pedestal has two replaceable blowers mounted at the rear.
•
The pedestal also has two foam blocks. These blocks ensure proper air circulation
and must not be removed. One block is mounted above the personality module, and
the other is located under the ac distribution unit between the feet of the pedestal.
