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 STATUS
LED comes ON, then after approximately a total of 10 seconds have elapsed, the SERIAL
ACTIVE LED also comes ON, to indicate that the Ethernet Interface will request entry to the
Maintenance state. After the Restart pushbutton is released, all 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 MODULE OK LED is
BLINKING fast and other LEDs are OFF.
Service Option Connector
If a problem occurs with the Ethernet Interface that requires continuous removal of power from
the rack or its removal from the rack, the on-board log event data will automatically be preserved
for 2–3 days. The service option connector allows you to attach a standard battery
(IC697ACC701) to save the log event data for longer periods.
Ports on the CMM742
There are two serial ports on the Ethernet Interface: the Station Manager port (RS-232) and the
Software Loader port (RS-485).
RS-232, RJ-11 Port (Station Manager Port)
The RS-232, 6-pin, RJ-11 “phone jack”, port is used to connect a terminal or terminal emulator to
access the Station Manager software on the Ethernet Interface. A cable is needed to connect the
terminal or emulator to the Ethernet Interface (see Appendix B, “Communications Ports
Characteristics”).
RS-485, D-Type Port (Software Loader Port)
The RS-485, 15-pin, D-type port is used to connect to the PC Software Loader in case the
communications software in the Ethernet Interface needs to be updated. The characteristics of
this port are given in Appendix B, “Communications Ports Characteristics”.
