Removal and replacement introduction
NOTE
Read the “Installation and safety considerations” before servicing.
The field-replaceable units (FRUs) in the Brocade 6520 can be removed and replaced without
special tools. The Brocade 6520 can continue operating during the FRU replacement if the
conditions specified in the procedures are followed.
DANGER
The procedures in this manual are for qualified service personnel.
Before beginning replacement
CAUTION
This document describes how to change field-replaceable units (FRUs) for units with either a
port-side air exhaust or a port-side air intake. You must replace a failed unit with the same type of
unit.
This applies to both power supplies and fans.
A new FRU must have the same part number (P/N) as the FRU being replaced. The
manufacturing P/N is located on the top of the FRU.
You can use external labels as a guide. Refer to Figure 8 . Both the power supply and fan FRUs are
labeled with an airflow symbol on the faceplate to indicate whether the assembly takes in or
exhausts air. The label also appears on the top of the assembly.
ATTENTION
All fans and power supplies must have the same airflow symbol (E or I) to be compatible with each
other.
