Restart and Enter Software Load State:

Pressing and holding the Restart pushbutton until the

bottom LED (STAT) turns ON (between 5 and 10 seconds) forces a restart and requests entrance
to the Software Load state. A reload is used to install a software update into the module and is
not part of normal operation. When the Restart pushbutton is pressed, all LEDs go out. After
approximately 5 seconds have elapsed, the STAT LED (bottom LED) comes ON, to indicate that
the Ethernet Interface will request a reload. After the Restart pushbutton is released, the three
Ethernet LEDs flash ON, then power-up diagnostics run, and the Ethernet Interface waits for the
software load with the three Ethernet LEDs blinking in unison.

Notes

Reloading the Ethernet Interface requires the attachment of the PC Software
Loader to the RS-232, RJ-11 port and initiating a load with the PC Software
Loader. The PC Software Loader is a separate software utility that updates the
communications software in the Ethernet Interface. This utility is supplied with
any updates to the Ethernet Interface software. See Appendix C, “Upgrading
the Ethernet Interface Firmware”, for more information.

At any time before you initiate a load with the PC Software Loader when the
Ethernet Interface is in the Software Load State, you can restart the Ethernet
Interface by pressing the Restart pushbutton. Pressing this pushbutton will
immediately cause the board to restart. If the reload has been initiated, see
Appendix C, “Upgrading the Ethernet Interface Firmware”, for more
information.

Restart and Enter Maintenance State:

Pressing and holding the Restart pushbutton until the

bottom two LEDs turn ON (approximately 10 seconds) forces a restart and requests entrance to
the Maintenance state. Maintenance state must be invoked to change Advanced Parameters.
While in Maintenance state, all Advanced Parameters revert to their default value. When the
Restart pushbutton is pressed, all LEDs go out. After approximately 5 seconds, the STAT LED
comes ON, then after approximately a total of 10 seconds have elapsed, the LAN LED also comes
ON, to indicate that the Ethernet Interface will request entry to the Maintenance state. After the
Restart pushbutton is released, the three Ethernet LEDs flash ON then power-up diagnostics run
and the Ethernet Interface enters the Maintenance state.

Notes

In any case, any data being transferred by the Ethernet Interface at the time of
the Restart will be lost.

The Restart pushbutton is not operable during the diagnostic phase of power-up.
The Ethernet Interface is in diagnostic phase when the EOK LED is
BLINKING fast and the other Ethernet LEDs are OFF.
