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.
The following table describes the LED status definitions.

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 53xx RAID or disk storage power cable
This document describes how to replace a NetBackup 5330 RAID or disk storage power cable to the
primary storage shelf or the expansion storage shelf while the appliance is operating. One of the
power cables to each storage shelf must be operating at all times.
Review the following:
• If both power cables must be removed at the same time on the Primary Storage Shelf, ensure that
there are no I/O operations on the appliance in progress, and then turn off the Primary Shelf.
• If both power cables must be removed at the same time on the Expansion Storage Shelf, ensure
that there are no I/O operations on the appliance in progress and power off the Primary Shelf.
After the Primary Shelf has powered off (all displays are completely off), then turn off the Expansion
Shelf.
This repair can be accomplished with the Primary storage shelf and the Expansion shelf installed in
the rack.

To remove the power cable
1Locate and identify the storage shelf that has the faulty power cable.
2Do the following as applicable:
• Disconnect the faulty power cable from the primary shelf.
Warning: Replace one power cable at a time only. If you need to remove both power cables
from the Primary Storage Shelf, ensure that there are no I/O operations on the appliance in
progress, and then turn off the Primary Shelf.
• Disconnect the faulty power cable from the expansion shelf.
Warning: Replace one power cable at a time only. If both power cables must be removed at
the same time on the Expansion Storage Shelf, ensure that there are no I/O operations on
the appliance in progress and power off the Primary Shelf. After the Primary Shelf has powered
off (all displays are completely off), then turn off the Expansion Shelf.
To install the power cable
1Verify that the AC power supply input for the storage shelves is within the range of 200 - 240 VAC
at 50/60 Hz, 9.13 - 10.95 A.
2Remove the replacement power cable from any wrapping.
3Do the following as applicable:
• On the Primary Storage Shelf, connect a power cord to the power supply socket. Connect the
other end of each cord to the appropriate AC power source.
