Wireless Solutions DualMode 800 Enclosure Maintenance Manual MTX08
Power-up procedure 4
Overview
Power-up procedures are used to inspect that the power cabling is correct and
to verify voltage checks.
Complete the power-up procedure before any equipment is plugged into the
equipment shelves.
Perform the procedure whenever a shelf or a unit such as the Alarm Control
Unit (ACU), the DualMode Cell Site Monitor (DCSM), or the High Stability
Master Oscillator (HSMO) is either removed or replaced. If the voltage or
polarity of the DC power is incorrect, equipment damage may result.
DC power inspection
An orderly installation of DC power is required at the enclosure to ensure
ease of expansion as traffic increases.
Step Action Observation
1 Verify that the DC power cables from the
breaker panel on the power bay to the
equipment bays have been run in an orderly
fashion and are secured to the runway.
2 Verify that the lugs have been installed
correctly and, if terminated on aluminum
busbars, have been treated with anti-oxidant.
3 Verify that the minimum bending radius has
not been exceeded on the power cables (see
Table 4-1).
