10/100Base-T LEDs And DIP Switches

The 10/100Base-T Ethernet interface has two indicator lights and two DIP
switches, as shown below.
Inspect the two LEDs on the 10/100Base-T Ethernet interface:
1. When an IP address is configured into the printer via the control panel,
the bottom LED should be blinking on and off at the same rate.
2. When a working network cable is installed, the top LED should be on
steadily and will blink off for 1/3 second when data are received.
When these two conditions are met, you should be able to ping the printer
from a network host.
You can test by starting a telnet session (telnet IP address ) and sending
start fox prn<Return>
stop prn<Return>
This command sequence sends consecutively numbered lines of text from the
interface to the printer. The "fox" test is resident in the network interface and
verifies that it can receive commands and can transfer data successfully to
the printer.
If no network cable is connected or the cable is defective and the IP address
is configured from the control panel, the top LED will be off and the bottom
LED will blink on/off.
