Ethernet Restart Pushbutton - GE RX3i User Manual

or unrecoverable runtime failure occurs, the EOK LED blinks a two-digit error code identifying the failure. For a
list of blink codes and their meanings, see Chapter 12.
Ethernet Port LEDs Operation (100Mb and Link/Activity)
Each of the two Ethernet ports (Ports 1A and 1B) has two LED indicators, 100 and LINK. The 100 LED indicates
the network data speed (10 or 100 Mb/sec). This LED is lit if the network connection at that network port is 100
Mbps.
The LINK LED indicates the network link status and activity. This LED is lit when the link is physically connected.
It blinks when traffic is detected at that network port. Traffic at the port does not necessarily mean that traffic
is present at the Ethernet interface, since the traffic may be going between ports of the switch.

Ethernet Restart Pushbutton

The Ethernet Restart pushbutton is used to manually restart the Ethernet firmware without power cycling the
entire system. It is recessed to prevent accidental operation.
Restart Pushbutton Operation for Version 3.6 and Later
For PACSystems Ethernet interfaces version 3.6 and later, an Ethernet restart occurs when the Restart
pushbutton is released. The duration that the Restart pushbutton is pressed determines the operation after the
restart occurs. In all cases, the EOK, LAN and STAT LEDs briefly turn on in unison as an LED test. The Ethernet
port LEDs are not affected by a manual restart of the Ethernet firmware.
To restart the Ethernet interface normally, press the Ethernet Restart pushbutton for less than 5 seconds.
If the Ethernet interface uses any optional Ethernet plug-in applications, these applications are ordinarily
started upon each power-up or restart. To restart the Ethernet interface without starting any Ethernet plug-in
applications, press and hold the Ethernet Restart pushbutton between 5 and 10 seconds.
To restart the Ethernet interface into firmware update operation, press and hold the Ethernet Restart
pushbutton for more than 10 seconds. This is typically done during troubleshooting to bypass possibly invalid
firmware and allow valid firmware to be loaded using WinLoader.
Pushbutton-controlled restart operations are listed below, with the LED indications for each.
Restart Operation
Restart the Ethernet interface normally, and start any
optional Ethernet plug-in applications that are being
used.
Restart the Ethernet interface without starting any
Ethernet plug-in applications.
Restart the Ethernet interface into firmware update
operation.
When forced into firmware update operation, but before the firmware update actually begins, pressing the
Ethernet Restart pushbutton again exits the firmware update mode and restarts with the existing firmware.
Once the firmware update actually begins, the existing firmware is erased and the Ethernet Restart pushbutton
is disabled until the firmware update is complete.
Restart Pushbutton Operation Prior to Version 3.6
For PACSystems Ethernet interfaces earlier than version 3.6, pressing the Ethernet Restart pushbutton restarts
the module immediately. The EOK, LAN and STAT LEDs briefly turn on in unison as an LED test. These three LEDs
are turned on for ½ second and are then turned off when the firmware is restarted. The Ethernet port LEDs are
not affected by a manual restart of the Ethernet firmware.
