Maintenance and Troubleshooting
Error Codes
Error Codes
The software system will recognize and return both system and setup errors. These
error codes provide troubleshooting clues for the user and Customer Service use in
solving configuration and system errors. If a software error is returned to the display
screen, follow the procedure below:
1. Record the error exactly as it appears on the screen.
2. Complete the troubleshooting flow chart in this chapter to isolate and/or
correct any problem before going to step 3.
3. Contact Customer Service for assistance. Have the error message and other
pertinent information (e.g., system log) readily available.
NOTE: The remainder of this chapter is based upon the assumption that
there are no system or setup software errors. Therefore, it is important to
clear all such errors before proceeding.
Redundancy
The Broadmore 1750 configuration has redundancy that serves to minimize system
downtime. Troubleshooting alerts for redundant components are clearly indicated on
the LEDs as explained below:
Power supply: a problem to either module is indicated by LED and log entry. The
unit can be replaced without impact to system operation.
NIM: a problem will give a fault on the online NIM with log entry and the backup
assumes control so a module replacement can be done without impact to system
operation.
SAM: the 1:N protection SAM in slot P takes over for the faulty unit that can then
be replaced without further impact to system operation. A log entry is also
provided to alert the operator.
CPU Sync: a problem synchronizing files between redundant CPUs (see below).
