Common Power Supply Verification
The procedure in Table 2-5 must be performed on any BTS frame
connected to a common power supply at the site after the common power
supply has been installed and verified per the power supply OEM
suggested procedures.
Perform the following steps to verify the power input is within
specification before powering up the individual cards/modules with the
frames themselves.
Table 2-5: Common Power Supply Verification
Step Action
1 Physically verify that all DC power sources supplying the frame are OFF or disabled.
2 On the RFDS (for +27 V systems only), set the input power switch P1 to the OFF position (see
Figure 2-7).
3 On each frame:
Unseat all circuit boards (except CCD and CIO cards) in the C-CCP shelf and LPA shelves, but
leave them in their associated slots.
Set breakers to the OFF position by pulling out C-CCP and LPA breakers (see Figure 2-3 on
page 2-8 or Figure 2-5 on page 2-10 for breaker panel layout if required).
- C-CCP shelf breakers are labeled CCCP-1 , 2, 3 in the +27 V BTS and labeled POWER
1,4,5,2,6,7,3,8,9 in the -48 V BTS.
- LPA breakers are labeled 1A-1B through 4C-4D.
4 Inspect input cables, verify correct input power polarity via decal on top of frame (+27 Vdc or
-48 Vdc).
5 Apply power to BTS frames, one at a time, by setting the appropriate breaker in the power supply that
supplies the frame to the ON position.
6 After power is applied to each frame, use a digital voltmeter to verify power supply output voltages at
the top of each BTS frame are within specifications: +27.0 Vdc or -48 Vdc
nominal.
