Document Number: 135
Version: 3.2 (03/06/17)
Purpose
This document describes the process for replacing a fan canister in a Primary Storage Shelf or an
Expansion Storage Shelf.
Affected Models
• NetBackup 5330 Appliance
• Velocity 7330 Appliance
Electrical Safety
The static discharged by human bodies can damage static-sensitive components on the boards.
When installing and maintaining the equipment, observe appropriate electrostatic safety precautions
to prevent personnel injuries or device damage.
When operating a device in an electrostatic sensitive area, you must take electrostatic-discharge
(ESD)-preventive measures. These include wearing ESD-preventive gloves, an ESD-preventive wrist
strap, and ESD-preventive clothes to avoid personnel injury or device damage.
To prevent damage to the device, pay attention to the following during operations:
• Do not touch devices with bare hands because ESD from the human body may damage the
electrostatically sensitive elements on a board.
• When dealing with the server or any of the internal components, wear an ESD-preventive wrist
strap, ESD-preventive gloves, and ESD-preventive suit.

Action Allowed mode.
The Service Action Allowed LED is located on the rear of the fan canister and it should be glowing
the color blue. Each canister contains one of these LEDs. Be sure to work on the canister that
