MONITORING AND TROUBLESHOOTING

3-4

3.1.3 16 Mb - Ring Speed 16 Mbps

The 16 Mb LED indicates the ring speed.

AMBER indicates that the interface ring speed is set to 16 Mbps. 

OFF indicates that the interface ring speed is set to 4 Mbps. 

3.1.4 XMT - Transmit

The XMT LED indicates the transmitting status of the interface.

Flashing GREEN indicates the TRMM-4 is transmitting data.

Blinking RED indicates a beaconing condition on the ring.

OFF indicates that the interface is inactive.

Blinking RED together with the RCV LED indicates the interface is 
trying to insert into the ring. 

3.1.5 RCV - Receive

The RCV LED flashes AMBER for every packet received, regardless of 
source or destination. It indicates the load on the network.

Blinking RED simultaneously with the XMT LED indicates the interface 
is trying to insert into the ring.

OFF indicates no activity. 

3.1.6 NSRT - Insert

The NSRT LED indicates interface activity.

GREEN indicates that the interface is inserted into the ring and is 
participating as a station on that ring.

OFF indicates that the interface is not inserted into any ring.

3.2 TROUBLESHOOTING THE  NETWORK

This section describes troubleshooting procedures you can perform to 
diagnose and correct problems with the TRMM-4 and the MIMs in the 
MMAC. The following procedures can help resolve problems typically 
encountered with network installations.
