FRU Removal and
Replacement
This chapter describes removal and replacement procedures (RRPs)
used by authorized service representatives for all Sphereon 4500
Fabric 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. The notes do not necessarily apply to all
procedures in the chapter.
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. When performing procedures described in this chapter, follow all
DANGER and ATTENTION statements, and statements listed in
the preface of this manual.
3. 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.
4. 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 or management
server), and extinguish the amber system error (ERR) light-
emitting diode (LED) at the switch front panel.
