Configuring Token Ring
Configuration Using SAM
Chapter 252
Using SAM with PCI Systems
A SAM patch is required to configure PCI Token Ring. Refer to the
Release Notes.
Configuration is done using the Networking and Communications
Network Interface Card’s screen. Please refer to “Manual Installation
and Configuration” in Chapter 3 for details on performing manual
configuration.
NOTE Use either SAM or manual configuration, not both.
1. Select the Token Ring link to be configured.
2. Note that setting incorrect parameters can render your network
inoperable and will prevent the Token Ring link from connecting to
the network. Exercise caution while modifying parameters.
3. Enabling autosense will allow the link to sense the speed and duplex
setting of the network and configure itself. See items 1.f and 1.g in
the “Manual Configuration for PCI Systems” section in Chapter 3
before enabling autosense.
4. If autosense is enabled, the only remaining configuration items are
IP configuration, station address, and MTU. Skip to step (6) below.
For 100 Mb/s operation, select autosense, as it cannot be enabled
otherwise. 100 Mb/s can only be enabled on A5783A when using
autosense and when the adapter is connected to a 100 Mb/s port.
Also, software A5783A revision B.11.00.04 or later must be installed.
On-line diagnostics (IPR 9904 and later) may be used to distinguish
between A4930A (4/16 PCI Token Ring) and A5783A (4/16/100 PCI
Token Ring).
Alternatively, ioscan(1M) can be used to distinguish between A4930A
and A5783A if revision B.11.00.06 or later is installed.
Also, note caveats 1.a through 1.g in the “Manual Configuration for
PCI Systems” section in Chapter 3.
5. If autosense is disabled, speed and duplex must be configured.
Setting the speed to “0” (zero) is not supported.
