v
Up to eight RANS may be attached to one adapter total. If four are attached to line
one, then only four more can be attached to line 2.
v
RANs
must be numbered in ascending order. The RAN closest to the adapter is
assigned as node 1. No gaps in the numbering should occur. Example, numbering
RANs as 1, 3, 4 in a line will cause configuration problems.
Setting a RAN Node Number
The AIX asynchronous Communications Guide provides information about configuring
and running diagnostics on the 128 Port async Adapter and associated RANs. To
access the AIX asynchronous Communications Guide, see the AIX online
documentation.
The adapter identifies RANs by their node numbers. Each RAN in a daisy chain must
have a unique node number (
1n-4n), which must be set during installation. The node
numbers must be assigned in ascending order with the lowest number assigned to the
RAN closest to the 128-Port async adapter. The following figure shows the front panel
of a RAN.

To set the RAN node number, do the following:
1. Turn on the RAN and wait for the power-on self-test (POST) to complete.
2. When
P1
is displayed on the front panel seven-segment LED display, press the Left
Arrow button once. The current node number is displayed, for example,
1n
for node
1.
3. Press the Right Arrow button to advance the node number through the eight
possible settings ( 1n-8n).
4. When the desired node number is displayed, press the Left Arrow button again to
select the number. The display should now read Pn (indicating a pass condition). If
there was an error, the display reads
En.
In the case of duplicate node numbers, the RAN farthest from the host adapter
displays
En
, instead of
AC
, when the system is started.
Configuring the 128-Port async Adapter
When a 128-Port async adapter is installed in the HMC and the HMC is first used, the
adapter must be configured. To configure the 128-port async adapter in the HMC, two
configuration utilities must be run (/usr/sbin/digiConf and /usr/sbin/cxconf). To run the
utilities, do the following:
1. Obtain the root password from the customer.
2. To allow access to the HMC Microcode Maintenance as the hscpe user, contact
software support to obtain the password.
3. In the HMC Navigation area, click Problem Determination.
