System status LEDs
2.3.2.2 LEDs
The CXCM4 has three LEDs located on the front panel. These are used to display the alarm
status of the power system, CXCM4 progress and status during startup, and file transfers.
Alarm Conditions
The CXCM4 illuminates the LED that corresponds to the system alarm status. The following
show the corresponding alarm status for each LED color:
Green – OK, no alarms present
Yellow – Minor alarm is present (no major alarms)
Red – Major alarm is present.
Only one LED is illuminated at a time during alarm conditions.
Progress and Status Indication
The LEDs are also used in the following situations:
Base unit validation – all three LEDs are on at the same time.
File transfer – when recovering from invalid firmware application – the red LED is
illuminated.
2.3.2.3 Reset
A reset button is located on the front panel for restarting the CXCM4’s microprocessor. It takes
approximately 15 seconds before the display reappears after pressing the reset button.
NOTE:
Refer also to the software manual – always select the shutdown menu item before pressing the reset
button.
2.3.2.4 Ethernet
Port
The Ethernet port is designed for CXCM4 connection to a user supplied network (TCP/IP
secured by user) via a front panel RJ-45 jack and a standard network cable.
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a
standard network crossover cable.
2.3.2.5
RS-232 Serial (Craft) Port
Local access to the CXCM4 is possible through a front panel RS-232 serial port; using a null
modem cable. The communication protocol supports a web interface (via Microsoft® Internet
Explorer 6 or greater). The remote screen display is an enhanced version of the CXC’s front
panel display.
