Replacing the chassis fan subassembly

About replacing chassis fan subassemblies

Replacing a chassis fan subassembly consists of the following procedures:

There are three chassis fan subassemblies on the C3100/C6100 NetCache appliance. Each chassis fan subassembly has two fans. The chassis fans are secured to the front of the chassis.

Note
To maintain UL, CSA, and TUV safety certifications, you must obtain replacement chassis fan subassemblies from Network Appliance. Using unapproved replacement chassis fans voids the safety certifications.
