Install and Configure an 8-Port Asynchronous AdapterTo install and configure an 8-port asynchronous adapter, refer to the IBM Hardware Management Consolefor pSeries Installation and Operations Guide.To connect the cables from the processor subsystem to the 8-port asynchronous adapter, use the followingprocedure.Connect the Processor Subsystem to the 8-Port Asynchronous AdapterAt least one 8-port asynchronous adapter is required. Up to two 8-port asynchronous adapters can beinstalled. The D-shell connector on the rear of the adapter attaches to the 8-port expansion cable. Thecable is approximately 0.9 m (3 ft.), and on the other end, has a slim box (21.6 cm (8-1/2 in.) x 7.6 cm (3in.) x 3.8 cm (1-1/2 in.)) 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 HMC ports onthe managed systems.If you are using a second, redundant HMC, connect cables from all of the processor subsystem’s HMC1ports to the 8-port cable on one HMC, and connect all the processor subsystem’s HMC2 ports to the8-port cable on the other HMC.HMC to Processor Subsystem CablingThe following illustration shows cabling for both the 8-port asynchronous adapter and 128-portasynchronous adapter to the HMC and the processor subsystems. The top portion of the illustration showsthe 8-port adapter and the RS422 cable to support up to four system frames. For smaller systemconfigurations, the 8-port asynchronous adapter can be used for RS232 connections.The bottom portion of the illustration shows the 128-port adapter and the RS232 cables to support up to64 processor subsystems.TRS232 RAN (Remote Asynchronous Node)- RS232 ports to support up to 64 Processor Subsystems- Processor Subsystems have 9-pin D-shell female connectorsConnector matchinginterposersPort 1Port 2HMC128-PortAdapter8-PortAdapterRS422 port pairs support upto four framesBPCs have 9-pin micro D-shell connectors24 Eserver pSeries 655 Installation Guide
