Observing Basic Port
Information
The basic port information, such as link up, link down, transmit/receive
activity, enabled/disabled as well as auto partition can be easily monitored
through the
Port Indicators
located in the first row of the Front Panel
Display.
Figure 3.6 Port Indicators
A Port Indicator shows the activity of a given port such as link up (connected
and functioning properly), link down (not connected, but available), Tx/Rx,
enabled or disabled.
The Port Indicators show the ports that are linked up by intensifying the light
for the ports that are available. The example above shows that ports 1~4 are
linked up and port 6 is disabled.
While the ports are receiving or transmitting data, the port’s number is
flashing.
An amber frame around the port number indicates the administrator has
disabled the port.
If the frame is blinking, it means it has been partitioned automatically due to
an error condition.
Port Available, Link Up
