SYSTEM RACK
4-20
4.4 EIGHT SHELF 3000 SERIES SWITCH
The system rack is a framework for modules that
consists of up to 8-shelves with 13-slots per shelf. In
each shelf, 12-slots are for function modules and
1-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 interconnection wiring, routed
between shelves, and external devices.
4.4.1 POWER CONSUMPTION
The following tables shows the average voltage,
current and power for each supply voltage per card
(based on loading of 96 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 96 = 413W
413W
÷
0.7 = 590W
3.6 x 590W = 2,123 Btu/Hr
4.4.2 EQUIPMENT REQUIRED
•
Digital Multimeter, voltmeter resolution to
0.001V.
•
Transmission test set, HP 3551A.
•
IBM NT compatible computer, with NetSMM
Call Processing Software.
•
Two CIMs (023-3039-035)
4.4.3 VERIFY RESISTANCE OF BUS BAR AND
POWER SUPPLY LINES
1. Verify the Power Cables
are not
connected to a
power source.
2. Verify the Power Supplies are not installed in the
Power Supply shelf.
3. Measure the resistance from point-to-point and
verify the resistance as shown in Table 4-17.
