2.3.1 LEDs
The CXC has three LEDs located on the front panel. These are used to display the alarm status of the power
system, CXC progress and status during startup, and file transfers.
2.3.1.1 Alarm Conditions
The CXCI/CXCI+ 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.
2.3.1.2 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 Reset
A reset button is located on the front panel for restarting the CXCI/CXCI+ microprocessor.
Refer also to the software manual – always select the Reset menu item before pressing the reset button.
2.3.3 Modem Port (not available on the CXCI+, list 98)
The Modem port (front panel DB-9 connector, Figure 2) is designed for connection to Alpha Technologies’ Cordex
DC Modem #018-585-20.
CAUTION
Connect only Alpha-supplied modem and cable; otherwise, equipment damage can result.
2.3.4 Ethernet Port
The Ethernet port is designed for CXCI/CXCI+ connection to a user supplied network (TCP/IP secured by user)
via a front panel RJ-45 jack (Figure 2) 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.
