SYSTEM RACK
SECTION 4 SYSTEM RACK
4.1 TWO SHELF 3000 SERIES SWITCH
The system rack is a framework for modules that
consists of up to two shelves with thirteen slots per
shelf. In each shelf, twelve slots are for function
modules and one slot is reserved for the power
module. The power supplies for the shelves are
located in the lower portion of the rack framework.
The framework also provides support for interconnec-
tion wiring, routed between shelves, and external
devices.
4.1.1 POWER CONSUMPTION
The following tables shows the average voltage,
current and power for each supply voltage per card
(based on loading of 24 cards).
Total watts including TIM-DID is 5.74W.
Excluding the TIM-DID provides a total of 4.3W for
normal modules. The total wattage of the terminal is
found by multiplying the wattage of a module by the
number of modules.
Total Watts x No. of Modules = Terminal Power
The wattage required by the power supply is
found by dividing the total wattage of the terminal by
the efficiency of the power supply (0.7).
Terminal Power
÷
0.7 = Wattage of Power Supply
The BTUs per hour are found by multiplying a known
value (3.6) by the wattage required by the power
supply.
3.6 x Wattage of Power Supply = Btu/Hr.
EXAMPLE:
4.3W x 12 = 51.6W
51.6W
÷
0.7 = 73.7W
3.6 x 73.7W = 265 Btu/Hr
4.1.2 EQUIPMENT REQUIRED
1. Digital Multimeter, voltmeter resolution to 0.001V.
2. Transmission test set, HP 3551A.
3. IBM NT compatible computer, with Call Processor
Software.
4. Two CIMs (023-3039-035)
