1. With one-cabinet systems, the MFR card can be installed in the AUX1 or AUX2 slot, depending on whether an API card is used. With two-cabinet systems, placement of the MFR cards differs according to the cable kit used. With Cable Kit Version 1.1, one MFR is installed in the Master AUX1, and one MFR is installed in the Slave AUX1. With Cable Kit Version 1.2, both MFR cards are installed in the slave cabinet--one in the CPC slot and one in AUX1. (See page 6-10for instructions on installing MFR cards in double-cabinet systems.)
2. The API card is installed in AUX1 only when a CBL card is used.
3. Part VB-43110 includes both the CBL-M and CBL-S cards, as well as the required connect- ing cables. CBL-M is installed in the master cabinet, CBL-S in the slave cabinet.
