Before beginning the installation
The field-replaceable units (FRUs) in the Brocade VDX 6730 switches can be removed and
replaced without special tools. The switches can continue operating during the FRU replacements
if the conditions specified in the procedure are followed. This covers both the AC-DC (AC) and
DC-DC (DC) versions of the combined power supply and fan FRUs in the Brocade VDX 6730-32
switch and the separate power supply and fan FRUs in the Brocade VDX 6730-76 switch.
“Installing a DC power supply”
if you are installing a DC power supply for the first time.
NOTE
Read the
“Installation and safety considerations”
on page 9 before servicing.
CAUTION
This document describes how to change field-replaceable units (FRUs) for switches with either a
port-side air exhaust or a port-side air intake. You must replace a failed FRU with a FRU of the
same type. This applies to both power supplies and fan assemblies.
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.
The P/N ends in either -F (front-to-rear airflow) or -R (rear-to-front airflow). You must use a
replacement FRU that has the same airflow designator with the part number.
If a mismatched power source or fan assembly is installed by mistake, a warning is sent to the
console. The warning messages will be similar to the following:
•
For a fan mismatch: [WARNING, Brocade VDX 6730, MISMATCH in FAN Air Flow direction.
Replace FRU with fan air flows in same direction.
•
For a power supply or combined power supply and fan mismatch: [WARNING, Brocade VDX
6730, MISMATCH in PSU-FAN FRUS Air Flow direction. Replace PSU with fan air flows in same
direction.
