Maintenance
Maintenance of the StackMaster™ is required only when a StackMaster™
unit requires updating or fails. Recovery of a failed StackMaster™ unit
requires fault isolation, using methods provided in this section, and
corrective action. Corrective action is taken by simple procedures
described in this section or by contacting Transition Networks Technical
Support.
5.1
Fault Isolation
Use Table 5-1 for troubleshooting the StackMaster™ stack.
To use Table 5-1, locate the problem in the FAULT column. In the
PROBABLE CAUSE box next to the fault, find one or more probable
cause(s) associated with the fault. Examine each probable cause in turn,
beginning at the top. When the probable cause is identifed, take the
associated corrective action in the CORRECTIVE ACTION column.
