Scope and Introduction
The purpose of this appendix is to provide instructions on how to
connect an SC 614 BTS to an SC 4812ET Power Cabinet in order to
share DC power and battery backup support. For details regarding RF
cabling considerations for a SC 4812ET and a SC 614T BTS, see
Appendix E.
The SC 4812ET Power cabinet provides 27 Volts DC power to an
associated SC 4812ET RF Cabinet. For sites where the SC 4812ET will
be co–located with an SC 614 base station, it can be advantageous for
space and other considerations to be able to use the SC 4812ET Power
Cabinet as a DC source for both the SC 4812ET and SC 614 BTS.
