Connect the Serial Cables from the pSeries 670 to the 8-Port Async
Adapters
Up to two optional 8-port async adapters can be installed. The D-shell connector on the back of the
adapter attaches to the 8-port expansion cable. The cable is approximately 3 feet long, and on the other
end, has a slim box (8-1/2 inches x 3 inches x 1-1/2 inches) with 8 separate serial port connectors on it.
The cable is labeled ISA 8-Port Cable. Serial cables can be connected from any of the ports on the 8-port
expansion cable to the HMC1 ports on the managed systems.
If you are using a second, redundant HMC, connect cables from all the pSeries 670 HMC1 ports to the
8-port cable on the primary HMC, and connect all the pSeries 670 HMC2 ports to the 8-port cable on the
redundant HMC.
Note: The second HMC system serial port is reserved for use by the modem.
Installing the 128-Port Async Adapter
The 128-port async adapter is an option for the HMC. It must be configured by the service representative
when the HMC is installed. The 128-port async adapter software is included in the HMC base software
installation package.
This adapter provides the control function and connectors to attach eight 16-port remote async nodes
(RANs). When all eight nodes are attached, this combination provides 128 EIA-232 or RS-422
communication ports.
