Introduction
This document provides instructions for replacing a blower assembly in the PowerConnect B-DCX4S and the
PowerConnect B-DCX chassis.
To ensure continuous adequate cooling for the PowerConnect B-DCX, maintain three operating blower assemblies at
all times except for the brief period when replacing a blower assembly.
The PowerConnect B-DCX4S can continue operating during the replacement if the second blower assembly is
operating.
Time and items required
The replacement procedure for each blower assembly takes less than 5 minutes. The following items are required
for the blower assembly replacement:
• Replacement blower assembly
• Phillips #2 screwdriver
Removing a blower assembly
1. Before removing a blower assembly, verify that the other blower assemblies are functioning correctly. The power

screws are at the top and bottom of the assembly and on the DCX-4S they are on the left and right.
3. Support the blower assembly from beneath. Use the handle to remove the blower assembly.
