FRU Removal and
Replacement
This chapter describes removal and replacement procedures (RRPs)
used by authorized service representatives for all Sphereon 4300
Switch field-replaceable units (FRUs). Do not remove a switch FRU
until a failure is isolated to that FRU. If fault isolation was not
performed, refer to MAP 0000: Start MAP on page 3-6.
Procedural Notes
The following procedural notes are referenced in applicable removal
and replacement procedures.
1. Before removing a FRU, read the removal and replacement
procedures for that FRU carefully and thoroughly to familiarize
yourself with the procedures and reduce the possibility of
problems or customer down time.
2. After completing steps of a detailed procedure that is referenced
from another procedure, return to the initial (referencing)
procedure and continue to the next step of that procedure.
3. After completing a replacement procedure, clear the event code
reporting the failure and the event code reporting the recovery
from the Event Log at the SANpilot interface, and extinguish the
amber system error (ERR) light-emitting diode (LED) at the
switch front panel.
