2.1 Physical Description

2.1.1Chassis

The PWR-AVIS chassis are 3.5 inches (8.9 cm) high and mount in either 19- or 23-inch (48.3 or 58.4 cm) equipment racks. Reversible mounting brackets are provided for accommodating either rack type. The protective front cover slides into the chassis when circuit access is required. Hinged plates on the chassis mounting brackets provide an area for recording circuit identification.

The PWR-AVIS chassis contains 17 RIUs (one for test) in which LCJ jack access cards or amplifier cards are installed. Two slots are located at the front of the chassis for installing one or two (depending upon configuration) power supply module(s). Office power connections for the power supply module(s) are made, as required, via two sets of -48V and RET terminals at the rear of the chassis. An AC to -48VDC power adapter (PWR-AVIS-110-ST) may be used when a -48VDC power source is not available. A cable management tray at the rear of the chassis supports the IN and OUT cables from the Network Elements.

2.1.2Power Supply Module

The power supply modules slide into slots labeled PWR 1 and PWR 2 at the front of the chassis (see Figure 4). This DC to DC converter provides the necessary +5V power for the chassis. A green LED at the front of the power supply module, when lit, indicates that the power supply module is functioning properly.
