7 BTS3900C Cables The surge protection board cannot be positioned in slot 4 in the BBU to avoid interfering with power cables in the BTS3900C cabinet. 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.
