Switch Corrective Maintenance Manual.
This section lists preventive (routine) maintenance schedules for the
5ESS
®
-2000 switch. Preventive maintenance
is performed on a specified schedule to ensure continuing peak overall performance of the network.
Since peak load periods, features, recent change activities, growth, etc., vary widely in different offices, some tests,
such as routine exercise (REX), may not have specific test schedules that are best for all offices. In cases of this
type, the equipment test list (ETL) gives references where procedures, recommendations, and/or guidelines can be
found for the listed test(s).
