Troubleshooting
Symptom Action
The MCOM LED on the expansion
module is red or blinking green.
The expansion module is in the process of loading,
initializing, or registering. Wait a few seconds until
the LED is solid green for the module to be
connected to the main CPU.
If the LED continues to blink red slowly, the
expansion module has failed in the discovery process
with the main CPU. This could be related to one of
the following causes:
The main CPU is not fully powered up;
A cable between the main and expansion frame
(perhaps via the expansion LAN switch) is not
connected properly;
The rotary switch on the expansion module is not
set correctly;
The expansion frame is not defined in the site
configuration.
The MCNF LED on the expansion
module is flashing green after
having been solid green (i.e. after
connection to main CPU was
established.)
The Expansion module is disconnected from the
main CPU. Check cable connections.
The ERR LED on the expansion
LAN switch front panel is red.
The switch was unable to configure itself upon
startup or it has lost communication with the main
CPU module.
Check the Error Logger to read error message. The
switch may need to be replaced.
The communication LEDs on the
expansion LAN switch front panel
are not lit.
Check if the Ethernet cables are connected properly.
Check if the CPU on the main frame and the
expansion modules have the proper power.
The power supply is connected to
power sources and there is no
power in AUX1 and/or AUX2.
Check if the AUX connectors are off due to STS
Hardware Test or user application.
If not, check if the fuse associated with the AUX is
burned out and should be replaced. (One fuse for
AUX 1A/1B and another fuse for AUX 2A/2B.) See
Break-Fix Procedures chapter.
No communication with WAN, IP
Gateway.
Check the unit’s connection to the Ethernet.
The power supply is on, but certain
I/O modules are off.
If the I/O modules are DO EE relays, check if the 2-
pin TB is plugged into the 12VDO connector on the
main power supply.
