PRELIMINARY
Table 2-4: Initial Power–up (BTS) Procedure
n ActionStep
7 After all cards/modules have been seated and verified, use a digital voltmeter to verify that Power
Supply Module Output Voltages measured at the top of the frame remain within specifications:
– On –48V BTS: –48V DC
nominal
– On +27 V BTS: +27V DC nominal
– On AC BTS: 208 to 240V AC nominal
8 Repeat Steps 1 through 7 for additional co–located frames (if equipped).
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 Power Supply Module suggested procedures.
Perform the procedure in Table 2-5 to verify that the Power Input is
within specification before Power–up is attempted on the individual
cards/modules with the frames themselves.
Table 2-5: 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 on each BTS Frame:
2a Unseat all circuit boards (except CCD and CIO Cards) in the SCCP Cage and LPA Shelves, but
leave them in their assigned slots.
2b Set the SCCP and LPA Circuit Breakers to the OFF position by pulling them out.
– 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.
3 Remove the Power Supply Modules.
4 Inspect the Input Cables to verify that the Input Power Polarity is correct according to the decal on
top of the frame.
5 Apply power to the BTS Frames one at a time.
6 After power is applied to each BTS Frame, use a digital voltmeter to verify that Power Supply
Module Output Voltages at the top of each BTS Frame are within specifications:
– On –48V BTS: –48V DC
nominal
– On +27 V BTS: +27V DC nominal
– On AC BTS: 208 to 240V AC nominal
