Run and Auto Reset Modes
Run mode is the normal operating state of the Ethernet Interface.
Auto Reset mode is entered when the watchdog timer is triggered
and the Print Server resets itself. In either mode, the STAT LED
flashes at a varying rate, depending on whether the unit IP address
is configured. The Run Mode and Auto Reset Mode indicator
descriptions are given in Table 1.

The NET LED displays the status of the network link. When the
NET LED is on, link integrity is confirmed. The NET LED flashes off
for 1/3 second when a data packet is being transferred. When the
NET LED is off, the network connection has been severed.
