Configuration Principles
l The BTS3900C cannot provide enough space for an SLPU. Therefore, surge protection
boards need to be installed in the BBU subrack.
l The surge protection board cannot be positioned in slot 4 in the BBU to avoid interfering
with power cables in the BTS3900C cabinet.
l The number of surge protection boards (UELP/UFLP/UFLPB) is based on the number of
E1/FE/GE ports that need surge protection in the BBU. The surge protection board is
installed, in descending order of priority, in slot 5, 1, or 0. If slots 5, 1, and 0 are occupied,
the surge protection board can be installed in a vacant slot in the BBU.
l Either the UFLPB or UFLP, but not both of them, can be installed in the surge protection
box. The UFLPB or UFLP is installed in a slot with a higher priority than the UELP.
l The FE/GE fiber optic cables do not need surge protection.
