Recovering Link Peripheral Processors - Nortel DMS-100 Manual

Application
Use this procedure to recover link peripheral processors (LPP) or fiberized
LPPs (FLPP) that are system busy (SysB).
Note: Throughout this document, LPP is used to refer to both the LPP and
FLPP.
LPPs become SysB when both link interface module (LIM) units lose A and
B dc power feeds. If the whole switch loses power, restore primary switching
functions. Do not use this procedure until the primary switching functions are
restored. To restore primary switching functions, use the procedure
Recovering from a dead system in a SuperNode switch. Or refer to the
Recovering from a dead system in a SuperNode SE switch procedure. The
procedure indicates when to recover the LPP.
To recover LPPs when both LIMs are system busy because of other faults, refer
to the procedure Clearing a PM LIM critical alarm and Alarm and
Performance Monitoring Procedures.
Action
This procedure contains a summary flowchart and a list of steps. Use the
flowchart to review the procedure. Follow the steps to perform the recovery
task.
