6 Maintenance
Note: Check your sales order and equipment warranty before attempting to service or repair the mBSC-C system. Breaking
the seals on equipment under warranty will void the warranty. Do not return equipment for warranty or repair until proper
shipping instructions are received from the factory.
6.1 Electrostatic Discharge Precautions
The mBSC-C system modules contain assemblies and components which are sensitive to electrostatic
discharge (ESD). Carefully observe the precautions and recommended procedures to verify that system
reliability is not compromised due to component damage from static electricity.
The following precautions will significantly reduce the risk of system failure or malfunction due to ESD:
1. Always wear a grounded wrist strap while working around the system
2. Consider all assemblies, components and connections to be ESD sensitive
3. When unpacking circuit boards, interfaces and modules that are packaged separately from the
system, keep them in their conductive wrapping until they are ready to be installed.
4. Before removing or replacing any components, select a work area where potential static sources
are minimized
5. Handle circuit packs and boards by the grounded housings, avoiding contact with the connectors
6.2 Preventative Maintenance
The mBSC-C system requires minimal regular maintenance to ensure continuous and satisfactory operation.
Maintenance includes diagnosing and correcting the service problems as they occur. When an alarm is
reported, it is necessary to follow a troubleshooting procedure to identify the source of the problem.
The following are recommended routine maintenance procedures:
Check the indicator status LEDs (normal or alarm).
Prevent dust or grime from accumulating on the surface of heat sinks.
Check power output.
6.3 Fault Detection and Alarm Reporting
The mBSC-C on-board embedded firmware detects unit and system faults and reports them as system
alarms. The following methods may be used to report alarms:
Dry-contact alarm points
Status LEDs on system components
NMS (Local GUI, remote NMS, and SNMP Alarms)
