FRU removal and replacement procedures
The field-replaceable units (FRUs) in the Brocade ICX 6650 can be removed and replaced without
special tools. The switches can continue operating during the FRU replacement if the conditions
specified in these procedures are followed. This covers both the power supply unit (PSU) FRUs and
fan FRUs.
CAUTION
This document describes how to change FRUs for units with either an air intake or air exhaust.
You must replace a failed FRU with a FRU of the same type. 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.
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 ICX 6650, MISMATCH in Fan Air Flow direction.
Replace FRU with fan air flows in the same direction.
•For a power supply: [WARNING, Brocade ICX 6650, MISMATCH in PSU Air Flow direction.
Replace PSU with air flows in the same direction
