Maintenance
Caution:
Lithium Battery
The Mini-Carrier Remote circuit packs contain a lithium battery, and there is a danger of
explosion if the battery is incorrectly replaced. The battery will be disposed or recycled by
the repair depot.

Maintenance overview

MCR maintenance deals with three types of problems:
• installation,
• daughterboard replacement, and
• operation.
Installation problems are those problems that occur with MCR during the installation of an
entire system or during the addition of MCR to an existing system.
Daughterboard replacement is performed in response to upgrades and daughterboard failures.
See

Installing or replacing an MCR daughterboard

the daughterboards.
Operation problems (for example, component failure or accidental equipment disconnection)
are those problems that occur during normal system operation.
In either case, problem identification should be approached systematically. A problem may
have more than one cause. To isolate the cause, a knowledge of Mini-Carrier Remote operation
is required. This information can be found in
identified, the problem can be corrected by replacing the defective card, connecting
accidentally disconnected cables, or correcting software problem(s).
The system provides built-in self-diagnostic indicators, as well as software and hardware tools.
These diagnostic facilities simplify system troubleshooting and reduce Mean-Time-To-Repair
(MTTR).
This document focuses on the maintenance of Mini-Carrier Remote equipment at the remote
site and in the system. It requires that non-Mini-Carrier Remote system elements operate
correctly before diagnosing Mini-Carrier Remote problems. For more information on
maintaining the entire system, refer to Avaya Communication Server 1000M and Meridian 1
Large System Maintenance, NN43021-700 and Avaya Communication Server 1000M and
