DESCRIPTION
The following is a description of the mechanical and electrical
components, as well as the characteristics of the input connections,
for the Power Supply module and Racks. Unless noted otherwise, the
descriptions that follow describe both M/N 57C493 and M/N 57C494
Power Supply modules.
2.1 Power Supply Module Mechanical Description
The M/N 57C494 Power Supply module is a printed circuit board
assembly that plugs into the leftmost position of the 6Ć, 10Ć, or 16ĆSlot
Rack. When it is installed in a 10Ć or 16ĆSlot Rack, there will be a
oneĆslotĆwide space to the right of the Power Supply. If desired, this
space can be covered with a blank faceplate (M/N 61C599).
The M/N 57C493 Power Supply module is a printed circuit board
assembly that plugs into the leftmost position of either the 10Ć or
16ĆSlot Rack. It cannot be used with the 6ĆSlot Rack. Both modules
are enclosed in protective steel housings with integral heatsink.
Through its connection to the Multibus backplane of the Rack, the
Power Supply module provides the DC voltages necessary to power
the logic circuitry of modules in the Rack. On the faceplate of the M/N
57C493 Power Supply module are two LED indicators, a terminal
block connector, a keyswitch, a fuse, and a battery backĆup
connector. See figure 2.1.
