Corrective Maintenance

Corrective maintenance refers to changing or replacing an element of the

system that is faulty. The MGC+ has several components in which problems

may occur:

• ReadiManager IAM

• Control Unit (CU)

• Function Modules:

• Network Interface Modules (ISDN/T1-CAS, IP and MPI and/or Serial)

• MUX+ Modules

• Audio+ Modules

• Video+ Modules

• Data Modules

• I/O Cards

• Power Supply Module

• Fans

Before replacing parts:

• To ensure a part needs replacing, complete the troubleshooting

procedures.

• Identify exactly which part needs replacing.

• Make sure you have the correct replacement part on hand.

• Make sure you are using proper ESD equipment, to prevent damage to

the system.

Warning!

• All maintenance tasks are to be performed by qualified, authorized

personnel.

• Use only replacement parts supplied by your dealer.

• Follow all procedures. Do not skip any steps.

Unless specified differently, the procedures described here are the same for

both the MGC+100 and the MGC+50.
