2.1 Expansion Pedestal Cabinet
The expansion pedestal cabinet is a modular free-standing storage cabinet that is
completely self contained with dual fan-cooled power supplies, an internal Ul-
traSCSI single-ended extender module, and an internal EMU circuit board. The
cabinet dimensions are the same as the subsystem base pedestal which houses the
controller and is normally installed within one meter of the base cabinet to facili-
tate the cable connections between the two units. Figure 1-2 identifies the ex-
panded subsystem's SBB slots and they’re corresponding SCSI Id addresses. Fig-
ure 1-3 identifies the items on the rear panel power supplies. The characteristics
of the expansion pedestal cabinet are outlined below.
