Twinax Attachment of Network Stations
131
Network Stations can be on port 1 or any other available port that does not
have NPT’s connected. This type of configuration is not mandatory but is
suggested for performance reasons.
When a twinax IBM Network Station is powered on for the first time, it
prompts you to specify the address to use for the port to which it is
connected.
This is not the TCP/IP address
.
It is an address, from 0 through 6,
to use on the workstation controller port to which the IBM Network Station is
connected.
Follow these steps to configure the IBM Network Station to use over twinax:
1. Power on the IBM Network Station after it has been cabled correctly.
2. When prompted to do so, specify the local controller address to use (range
is from 0 to 6).
The IBM Network Station checks to see if any other device is using that
address. If not, the particular address is accepted. If the address is in use
by another device, a message
Station Address in Use is displayed and
another address must be chosen. Proceed with choosing another address
(in the 0 to 6 range) until one is accepted.
If you are not prompted for an address, then one has already been defined
for the IBM Network Station. After the station powers up, bootup
messages are logged. On a twinax IBM Network Station, one of those
messages is
NS0065 Twinaxial station address...x, where x is an address
from 0 to 6.
If an address has been defined, there may be other configuration
parameters present on the Network Station. For a twinax IBM Network
Station, limited configuration is required. If you suspect the Network
Station has been configured before, we recommend that you
