Figure 18-14. High Speed Communications PCB Option
High Speed Communications PCB Option (686B599U01)
1. These option cards occupy Expansion Board slots 1 (J connector 9 and 10) and 2 (J connectors
7 and 8). The MicroLink Network B High Speed Communications PCB occupies slot 1 and the
MicroLink Network A High Speed Communications PCB occupies slot 2. The High Speed
Communications PCBs provide controller rear connectors J6 through J9. J6 and J7 come from
the slot 2 board, and J8 and J9 come from the slot 1 board.
2. Each PCB provides peer-to-peer communication through the External I/O Module (see Config-
uration Table 5-8). (See also IB 53MC9011, MicroLink.)
3. A Communications ITB (686B622U01) may be required as determined by the controller position
in the MicroLink network configuration. The Communication ITB is cable connected to a High
Speed Communications PCB jack, J6 through J9.
4. The controller must be expansion ready.
5. The MicroLink Network B High Speed Communication PCB option is mutually exclusive with the
slot 1 Auxiliary Processor Board (APB) and therefore any option that may require that board.
