6. Specify whether you want to enable or disable the port by selecting the appropriate
option button.
Disabled ports do not send or receive any traffic. You might want to disable unused
ports to prevent network users from inadvertently or unscrupulously connecting to
unoccupied but enabled ports on the SSR.
7. Do one of the following:
– If you want the port to detect and then use the operating mode and speed of the
network segment to which the port is connected, select the
Autodetect Port Duplex
Mode and Speed check box. Otherwise, clear the check box to disable autodetection
on the port.
All 10/100 Mbps Ethernet and Gigabit Ethernet ports use autodetection by default.
The 100 FX ports do not use auto-detection. They always use full-duplex mode and
operate at 100 Mbps.
– If you want to set the port’s operating mode or speed to a specific setting, select the
appropriate buttons.
Note:
If you select an operating mode or speed, the setting disables autodetection
for that parameter on the port. For example, if you set the speed of a segment
to 10-Mbps, that segment no longer uses autodetection for the port speed and
will always attempt to operate at 10-Mbps.
