This document describes how to replace an existing FAN Unit fixing bracket with a new more secure FAN Unit
fixing bracket. The new bracket restricts the FAN Unit movement to less than 3.2 mm to prevent accidental
unseating and loss of cooling.
The FAN Unit fixing bracket is located vertically between the FAN Units. The brackets have a hinge on the
bottom and a screw on the top and secure the fans in place. The retention kit includes a fixing bracket tool
(345-1443-01) to simplify the loosening of the hinge pin.
This is a hot-swap procedure that can be implemented while the system is running.
