This document describes the process for replacing a power canister in a NetBackup 5330 Primary
Storage Shelf or an Expansion Storage Shelf.
Affected Models
Veritas NetBackup 5330 Appliance Storage Shelf
The NetBackup 5330 Appliance Primary Storage Shelf and Expansion Storage Shelf each contain
60 SAS hard disk drives. The front panel of the Primary Storage Shelf and Expansion Storage Shelf
contain five drawers, which are numbered 1-5, starting with the top drawer. Each drawer contains 12
disk drives, numbered 1 - 12, starting at the front left corner. The front panels of both systems are
physically and functionally the same, as seen in the following diagram.
The following diagram shows the front panel LEDs. The table identifies the components.

Each storage system contains two fan canisters on the left and right sides of the rear panel.
Fibre channel (FC) cables connect the Primary Shelf to the appliance.
Four SAS cables connect the Expansion Shelf to the Primary Shelf. The Expansion Shelf is not directly
connected to the appliance.
Onsite Policies and Procedures
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.
Hardware part replacement procedure
Removing and replacing a power canister
Before you start to replace a power canister in the NetBackup 5330 Primary Shelf or Expansion Shelf,
gather antistatic protection and a replacement power canister.
Warning: If you perform this procedure with the power turned on, you must complete it within 15
minutes to prevent the possibility of overheating the equipment. Do not remove both power canisters
from the storage shelf at the same time. One power canister must be functioning at all times.
Caution: To prevent electrostatic discharge damage, use proper antistatic protection when handling
components.
Power canister locations
The power canisters for both storage shelves are located in the rear panel of the shelf. One canister
is located at the top and at the bottom of the shelf. Each canister has two orange levers that disengage

the canister from the chassis of the storage shelf. The levers of the replacement power canister secure
the new canister in place.
To remove a power canister
1Locate and identify the storage shelf that has the faulty power canister.
2Before you begin service on the affected canister, verify that the component is in the Service
Action Allowed mode. Check that the Service action allowed LED is blue. Each canister contains
one of these LEDs. Be sure to work on the canister that has the blue LED. Check the Power
Service Action Required LED to locate the failed power canister.

While removing the power canister, you might notice an increase in fan speed. The fan speed
returns to normal after you have replaced the power canister.
To install a power canister
1Unpack the new power canister. Save all packing materials in case you need to return the faulty
power canister.
2Pull the power canister levers toward you.
3Use the levers as handles to place the canister into the chassis of the storage shelf.
4Slide the canister all the way into the chassis.
5Rotate the levers toward the center of the canister to lock it in place.
6Be sure that the power switch on the replacement power canister is turned off.
7Plug in the power cord.
8Make sure that the power connector fits snugly into the canister receptacle.
9Attach the plastic strain relief to the power cord.
10 Be sure that the other end of the power cord is attached to a 220VAC power source.
11 Use the power switch on the new canister to turn it on.
12 Check the green Input AC Power LED and the amber Power Service Action Required LED on
the new power canister.
13 If the Input AC Power LED is on, and the Power Service Action Required LED is off the
replacement procedure has been completed.
14 If the Input AC Power LED is off, or the Power Service Action Required LED is on, check that the
power canister is installed correctly. Reinstall the power canister if needed.
15 If the LEDs are still not correct, contact Veritas Support.
