Connecting to a 128-Port Serial Adapter

The HMC, when shipped with a pSeries 690 frame, comes installed with a 128-port serial adapter. Use
converter RS232 to RS422 (part of feature code 8122 and 8123) when cabling the HMC to the BPC. Use
the following cable diagram as a reference, when cabling a system using the RS232 to RS422 converter.
To configure a 128-port adapter enter the following
Go to the System Configuration menu and do the following:
1. Open Configure Serial Adapter and enter 1 to select Configure Serial Adapter(s).
Notes:
a. All serial adapters in the system must be configured at the same time. When adding additional
adapters, the original adapters must also be reconfigured. If you do not reconfigure the original
adapters, its original definition will be lost.
b. This step configures the serial adapters. The ports used for RS-422 service on 8-port adapters will
get configured later. Ports on the 128-port adapters do not need to be configured for RS-422
service.
2. When prompted for the number of boards to install, enter the total number of 8-port and 128-port
adapters in the system.
3. When prompted for the board type, enter 16 (128-Port async PCI)
4. c. When prompted for the number of ports on the digiBoard, you will be presented with a list of
possible values.
a. Count the total number of Enhanced RANs you are attaching to the 128-Port async adapter and
multiply by 2.
b. Enter the selection number associated with the actual number of ports on the enhanced RANs.
5. When prompted to set Altpin, enter n (for no).
6. If two 128-port adapters are installed, the utility repeats the question sequence. Use the listed answers
for each adapter.
