PA-4R Half-Duplex Token Ring Port Adapter Installation and Configuration
OL-3589-01
What Is the 4R Port Adapter?
Figure 4 Port Adapters in the Cisco 7206
4R Port Adapter LEDs
The 4R port adapter has several LEDs that indicate status of the port adapter and its interfaces. After
system initialization, the enabled LED goes on to indicate that the 4R port adapter has been enabled for
operation. (The LEDs are shown in .)
Figure 5 4R Port Adapter LEDs (Partial Faceplate View)
The following conditions must be met before the enabled LED goes on:
• The port adapter is enabled for operation and correctly connected
• The port adapter is receiving power
• The system contains a valid microcode version for the port adapter
If any of these conditions is not met, or if the initialization fails for other reasons, the port adapter’s
enabled LED does not go on.
When a Token Ring interface is configured by using software commands, the In Ring and 4/16 Mbps
LEDs (shown in ) indicate the following for each port:
• In ring—Goes on when the interface is currently active and inserted into the ring; off when the
interface is not active and is not inserted into a ring.
• 4/16 Mbps—Goes on if the interface is operating at 16 Mbps; off when the interface is operation at
4 Mbps (default).
