Hardware Descriptions
This chapter describes the hardware for OfficeServ500 systems, as follows:
y
System Cabinets
y
Common Control Cards
y
Interface Cards
y
Station Equipment
System Cabinets
System cabinets are made of metal and are therefore robust. They are used as the main
cabinet / key service unit (KSU), or as expansion cabinets in ‘L’ systems where they can be
stacked up to three high to achieve maximum capacity. Cabinets may be wall mounted or—
for multiple cabinet systems—may be mounted in a standard 19-inch equipment rack after
removal of the side panels and their supporting brackets. Each cabinet comprises the
following:
y
Eight universal interface card slots (or six for ‘S’ systems)
y
One dual-purpose interface card / signal processor slot (see
Chapter 1)
y
One processor card slot
y
Two power supply slots
y
One IOM board slot for the main cabinet/KSU (see
this chapter).
y
AC power connector
y
DC power (Battery Backup) connector
NOTE: The first power supply slot must be occupied by a PSU-B power supply to supply
sufficient power to all 10 slots (8 interface, one dual purpose and one processor slot). A
second PSU-B may optionally occupy the second power supply slot.
