Setting the Ring Speed
Token Ring Switch Module User Guide Page 3-3
3.4 SETTING THE RING SPEED
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.
3.5 CONFIGURING THE BRIDGING TYPE
3.5.1 Transparent
The ATX defaults to transparent bridging for all ports. If this is
acceptable, no further configuration is necessary.
!
CAUTION
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.
