Affected Models
NetBackup 5240 Appliance
The NetBackup 5240 Appliance is a hardware and software storage system that can scale to 220 TB
of available backup capacity. It consists of a NetBackup 5240 Appliance and up to four optional
NetBackup 5240 Appliance Storage Shelves. By itself, the 2U NetBackup 5240 Appliance offers
internal data storage from 4TB to 27TBs, depending on the storage configuration you purchase. When
additional storage is required, you can attach up to four 2U storage shelves to the NetBackup 5240
Appliance. Each NetBackup 5240 Appliance Storage Shelf offers 49TBs of backup storage capacity.
Attaching four storage shelves offers 196TBs of storage, in addition to the internal storage that is
available with the NetBackup 5240 Appliance.
SAS-3 cables are used to connect the NetBackup 5240 Appliance to the storage shelves. SAS-3
cables are also used to connect the storage shelves to each other.

Warning: You must also unplug the unit from all AC power sources before you remove the cover. If
the power cords are still connected, internal standby voltages could harm personnel and equipment.
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
This section describes how to replace a 1-TB operating system disk drive or a 1-TB log file disk drive
in the NetBackup 5240 Appliance.
The NetBackup 5240 Appliance operating system is installed on two internal RAID 1 (mirrored )1-TB
hard disks. The operating system disks are located in drive bay slots 0 and 1. The appliance also
uses two internal RAID 1 (mirrored) 1-TB disk drives to store appliance software-generated log files.
The log file disks are located in slots 2 and 3.
Disk drive slot locations are shown in the following figure.

Caution: Only 1-TB drives can be used in slots 0 - 3. Make sure you do not replace the faulty drive
with any other size drive.
This repair can be accomplished with the appliance installed in the rack.
Caution: You must complete the hard disk drive swap within three minutes. Leaving the disk drive
slot open for longer than three minutes can result in the appliance overheating and cause other
components to fail.
Note: If the appliance has attached storage shelves, these do not need to be powered down while
the appliance is being serviced.
Requirements
