PRELIMINARY
Make sure the Connector Adapters are securely attached
to each of the BTS Power Feeds and Returns.
Also, make sure the cables have been properly installed
into each connector.
NOTE
Common Power Supply Module
Verification
The procedure in Table 2-5 must be performed on any BTS Frame
connected to a common Power Supply Module at the site after the
common Power Supply Module has been installed and verified per the
OEM suggested Power Supply Module procedures.
Perform the following steps to verify that the Power Input is within
specification before powering up the individual cards/modules within the
frames themselves.
Table 2-3: Common Power Supply Module Verification Procedure
n Step Action
1 Physically verify that all DC and AC Power Sources supplying the frame are OFF or
DISABLED.
2 Perform the following actions in each BTS Frame:
2a Unseat all circuit boards (except the CCD and CIO Cards) in the SCCP Cage and LPA Shelves,
but leave them in their associated slots.
2b Set the circuit breakers to the OFF position by pulling out the SCCP and LPA Circuit Breakers.
– SCCP Cage Circuit Breakers are labeled SCCP–1 and SCCP–2.
– CLPA Circuit Breakers are labeled LPA 1A–1D through LPA 2A – 2D.
– Refer to Figure 2-4 for the Circuit Breaker Panel layout if required.
1 Remove the Power Supply Modules.
2 Inspect the Input Cables to verify that the correct Input Power Polarity according to the decal on
top of the frame.
3 Apply power to BTS Frames, one at a time, by setting the appropriate circuit breaker in the Power
Supply Module that supplies the frame to the ON position.
4 After power is applied to each BTS Frame, use a digital voltmeter to verify Power Supply Module
Output Voltages at the top of each BTS Frame are within specifications:
– –48V BTS: –48V DC
nominal
– +27 V BTS: +27V DC nominal
– AC BTS: 208V AC to 240V AC nominal
5 Plug in the Power Supply Modules (PSMs) one at a time and verify that the PSM LEDs appear
GREEN.
