Universal Equipment Modules (UEMs) are self-contained equipment
modules which house system components such as card cages, circuit cards,
power units, mass storage units, and cabling.
Each UEM is approximately 80 cm (31.5 in.) wide, 52.1 cm (20.5 in.) deep
(55.9 cm (22.0 in.) with covers), and 43.2 cm (17 in.) high. The weight of a
UEM is approximately 21.8 kg (48 lbs) empty, including the top, bottom,
sides, side trim panels, card cage, Input/Output (I/O) panel, and
miscellaneous hardware.
All UEMs are equipped with a card cage assembly and a cover assembly.
Refer to
Circuit puck installation and testing
(553-3001-211) for the
identification and location of the different cards within each UEM.
A UEM that is populated with various hardware components is referred to
as a module. The different types of modules available are described in this
chapter.
Also described in this chapter are the main components of a system option
which can be ordered as a separate package. These components are the Top
Cap, the card cages, the pedestal, the Spacer Kit, and the Module Covers.
