Port Status
The TP ports and transceiver module ports (if modules are fitted) are
color coded to show their condition. To display this information in
the web interface, click Color Key:
■
Black — The port is enabled and has no connection.
■
Green — The port is enabled and has a connection.
■
Gray — The port has been disabled by management.
■
Red — The port has partitioned (disabled itself). This may be due
to:
■
A network loop — This occurs when there are too many active
paths around the network.
■
Receive jabber — This occurs when the transmitting device is
sending continuous data.
■
False carrier events — This occurs when poor quality cabling is
used for 100Mbps.
■
TP connector with a red cable — The connection has been
changed from 100Mbps to 10Mbps by Smart auto-sensing. This
may be due to poor quality cabling.
