The purpose of this appendix is to provide instruction on how to connect
two SC 4812ET cabinets to a single SC 4812ET Power Cabinet. Please
note that one fully loaded Power Cabinet (6 rectifiers) is rated only at
300A DC. As a result, only a total 9 Sector-carriers of capacity can be
supported in the two "co-located" RF Cabinets (e.g. one 3-sector,
1-carrier cabinet and one 3-sector, 2-carrier cabinet), or inadvertently
tripping the circuit breaker could result.
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 4812ET, it can be advantageous for space and
other considerations to be able to use the SC 4812ET Power Cabinet as a
DC source for the second RF Cabinet.
This section describes how to install and configure the equipment to
provide this functionality.
