Replacing a Modular Fan Assembly
This section describes how to remove and install a modular fan assembly for the chassis.
Caution
Do not use a fan assembly from another chassis. Doing so may damage
your chassis and the fan assembly.
Removal
The fan assembly (part number 782107-01) is a replacement part for the chassis. Before
attempting to replace a fan assembly, verify that there is adequate clearance in front of the
chassis.
The fans for this chassis are redundant and hot swappable. You can remove the fans with main
power connected to the system.
Caution
Use care when selecting which fans to remove, as an undesired system
shut down can occur. Do not remove both fans from the same column, as this
triggers a system shutdown.
Caution
Likewise, do not remove the working fan from the same column as a
failed fan, as this also triggers a chassis shutdown.
Caution
If all fans are installed and operating normally, you can remove any fan
without causing the system to shut down.
The following figure shows the PXIe-1086DC chassis with a fan assembly removed.
