● 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 IO Configuration page. If a link failure is indicated, try the following: ● Check cable connections. ● Manually configure the link setting to match the port configuration of the network hub or switch. For manual configuration methods, see Link configuration methods on page 36. Turn the printer off, then on again, to re-initialize the setting. ● Print an IO Configuration page and check link settings. Item Port Config Auto Negotiation Description 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. 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: You must manually configure the link speed and communication mode using the front panel. Your 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. If the printer is not able to connect to the network through auto-negotiation, you can set the link setting by one of the following methods: 36 Chapter 4 Network configuration ENWW
