Circuit Card Descriptions
fiber optic link electrical-to-light interface is implemented on a Fiber Interface Module
(FIM). The transmit and receive links of the fiber optic cable connects to the TX and
Rxfiber optic connectors on the FIM faceplate. The FIM plugs onto the Peripheral FIM
Carrier Card (PFC) and the PFC plugs onto the BAY Control Card via two 96 DIN
connectors.
There are two pairs of switches on the card; see Figure 3-l. All four switches must be
set to closed for normal operation.
