●
When the green light is on, the printer has successfully linked to the network.
●
When the yellow light is blinking, there is network transmission activity.
Link troubleshooting
If the printer does not successfully connect to the network:
●
Both LEDs will be off.
●
LAN Error- Loss of Carrier will be indicated on the Connectivity Configuration page.
If a link failure is indicated, try the following:
●
Check the cable connections, or try another cable.
●
Manually configure the link setting to match the port configuration of the network hub or switch. Turn
the printer off, then on again, to re-initialize the setting.
●
Print an Connectivity Configuration page and check link settings.
Item Description
Port Config If the printer is properly linked, this item has one of the following values:
●
10BASE-T HALF: 10 Mbps, half-duplex
●
10BASE-T FULL: 10 Mbps, full-duplex
●
100TX-HALF: 100 Mbps, half-duplex
●
100TX-FULL: 100 Mbps, full-duplex
●
1000TX FULL
If the printer is not properly linked, one of the following messages will appear:
●
UNKNOWN: The printer is in an initialization state.
●
DISCONNECTED: A network connection has not been detected. Check network cables. Reconfigure the
link settings, or restart the printer.
Auto Negotiation Indicates whether auto-negotiation for link configuration is on or off:
●
ON (default):The printer will attempt to automatically configure itself onto the network at the proper
speed and communication mode.
●
OFF: Manually configure the link speed and communication mode using the front panel. The settings
must match those of the network for proper operation.
Link configuration methods
The printer supports 10, 100, or 1000 Mbps network link speeds using full-duplex or half-duplex
communication modes (a 1000T half-duplex selection is not supported). By default, it will attempt to
autonegotiate its link operation with the network. When connecting to network hubs and switches that do
not support auto-negotiation, the printer will configure itself for 10 Mbps or 100 Mbps half-duplex operation.
For example, when connected to a nonnegotiating 10 Mbps hub, the print server will automatically set itself
to operate at 10 Mbps half-duplex.
