Switch Settings
You must set the switches on the dual base station interconnect board
correctly. The switch settings depend on the type of base station(s) installed
in the subrack, and on the part number (IPN) of the board itself.
Table 6.1 gives the switch settings for older boards with the part number
220-02037-02. This board can only be used with dual base stations using a
PMU.
Table 6.2 gives the switch settings for newer boards with the part number
220-02037-04 and later. These boards can be used with dual base stations
using a PMU, and with single or dual 12V PA base stations.
