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 an F800 series filer. 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.

Types of F800 chassis fan subassemblies

There are two types of chassis fan subassemblies:

Chassis fan subassemblies without a duct
Caution
This can only be used with the F820 and F840 filers that do not have keyed chassis fan bays.

Chassis fan subassemblies with a duct that can be used on all F800 platforms

Location of chassis fan subassemblies

The chassis fan subassemblies are behind the front bezel. The following figure shows the chassis fan subassembly locations with the front bezel removed. The sheet metal above the chassis fan subassemblies is silk-screened with the labels Fans 1-2, Fans 3-4, and Fans 5-6.

Removing a chassis fan subassembly

To remove a chassis fan subassembly, complete the following steps.

Note
Because the three fan subassemblies are hot swappable, there is no need to shut down the filer.

Step	Action
1	From the console, note the identification of the fan subassembly that failed.
2	Pull the bezel straight off the front panel of your filer by using the grooves on the left and right edges of the bezel.
3	Using a #1 Phillips screwdriver, loosen the thumbscrews on the chassis fan subassembly that failed.
4	Using the handle, pull the chassis fan subassembly straight out of the filer chassis. WARNING Use caution when servicing components in the chassis. There is danger of electric shock from hazardous energy on the backplane. Note If the filer is running Data ONTAP^TM software, it reports a failure for the removed fan assembly.
5	Set the chassis fan subassembly aside.

Installing a chassis fan subassembly

To install a chassis fan subassembly, complete the following steps.

Step	Action
1	Using the handle, slide the chassis fan subassembly straight into the filer chassis.
2	Tighten and then torque the chassis fan thumbscrews 8 to 10 in.-lbs.
3	Align the pins on the bezel with the holes on the front panel of the filer, then push the bezel straight onto the front panel.
4	Reconnect and turn on the power to the filer.
5	Interrupt the boot process by pressing the Delete key during the memory test.
6	Run diagnostics by entering the following command at the `ok>` prompt: sys-diag See the Diagnostics Guide for more information.
7	Run the diagnostics that apply to the unit you installed or replaced.
