Before the Token Ring module can be connected to a network, the ring 
speed must be set. Token Ring signaling takes place at either 4 or 16 
Mbps. The default setting is for 4 Mbps. All stations on the same ring 
must operate at the same speed. 

Using LCM, at the ATX> prompt, type 

ringspeed

 followed by the port 

number and the desired speed. For example, to set port 9 to 16 Mbps type:

ATX> ringspeed 9 16

The LCM displays 

16000000 bits/second

.

If set to 4 Mbps, LCM displays 

4000000 bits/second

.

The Token Ring modules include an LED for each Token Ring port that 
indicates for which speed the port is configured. If the port is configured 
for 16 Mbps, the LED will be on; if configured for 4 Mbps, the LED will 
be off. For Token Ring Switch Modules, set each port’s ring speed, if 
necessary.

The ATX defaults to transparent bridging for all ports. If this is 
acceptable, no further configuration is necessary.

A single station configured to the wrong speed may bring down 
the entire ring, therefore, the ATX should be configured to the 
appropriate speed before physically connecting it to the 
network.
