HMC Connections to the
Eserver
pSeries 655
Asynchronous adapters in the HMC are used to connect the HMC to processor nodes in the
Eserver
pSeries 655 and bulk power controllers (BPCs) in the racks. This section includes detailed information
about how to connect the HMC to processor nodes and BPCs. It also shows how these connections are
used in an
Eserver
pSeries 655 system.
Connecting an HMC to
Eserver
pSeries 655 Processor Nodes
One HMC can connect up to 16
Eserver
pSeries 655 processor nodes in up to 4
Eserver
pSeries
7040-W42 racks by using RS232 cable connections. These connections can be made from an HMC by
using the asynchronous ports on FC 2944 (128-Port Asynchronous Controller) or FC 2943 (8-Port
Asynchronous Controller). An integrated port (using RS232) on the HMC is also available to be used to
connect to a processor node.
The following table lists the features used to make the RS232 connections from FC 2944 (128-Port
Asynchronous Controller) to
Eserver
pSeries 655 processor nodes.

Notes:
1. Each FC 8137 requires a 98xx power-cable-specify feature code.
2. FC 8132 is used as a connection between two RANs (FC 8137) when multiple RANs are used.
For more information about using FC 2944 to
Eserver
pSeries 655 processor nodes, see the illustration
