Rail Replacement: 2U12 Storage Shelf
Document Number: 180
Version: 4.1 (05/04/2020)
Purpose
This document describes the process for replacing the rails for a 2U12 Storage Shelf
Affected appliance models
• 5240 2U12 Storage Shelf
• 5250 2U12 Storage Shelf
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.
About replacing the 2U12 Storage Shelf rails
This document describes how to replace the rails that hold the 2U12 Storage Shelf in the rack.
You must remove the storage shelf from the rack to replace the rails. Before the storage shelf can
be removed from the rack, all running programs on the connected appliance must be stopped, and
the appliance and the storage shelf shut down. If there are other connected storage shelves, they
must be turned off as well.

Veritas Appliance
Hardware Service Procedure

Make sure that you have a large, level, ESD-compliant work surface on which to set the appliance
and spare parts.
Warning: The storage shelf weighs in excess of 71 lbs (32 kg). Use appropriate tools and techniques
to lift and move the storage shelf.
Requirements
Verify that you have the following items:
• 2U12 Storage Shelf replacement rail kit
• Philips screwdriver
• ESD wrist strap
Removing the storage shelf from the rack
To remove the storage shelf from the rack
1Verify the serial number of the storage shelf or the appliance that the storage shelf is connected
to.
• On the 5240 and 5250 appliance, the serial number begins with the letters VTAS, and is
located on a label on the rear panel of the appliance.
• The storage shelf serial number is located on a white tab on the left side of the rear panel,
between the left-hand power supply and the chassis case. Pull out the tab to display the serial
number.

2Before you perform service, the appliance that the storage shelf is attached to needs to be turned
off with a soft shutdown. A soft shutdown informs the NetBackup Appliance operating system to
stop and close all active processes. A soft shutdown also stops all communications to the attached
storage shelf or shelves. After the operating system stops all of the processes, the appliance
powers itself off.
To perform a soft shutdown, use the Support > Shutdown command in the NetBackup Appliance Shell
Menu.
Note: Before performing a soft shutdown, ensure that all backup and restore operations have
been completed.
Warning: You should never perform a hard shutdown by using the power button to turn off the
NetBackup Appliance. Using the power button to turn off the NetBackup Appliance can cause
data corruption to occur.
3After the appliance is shut down, you must turn off the storage shelf and any other storage shelves
that are attached to the appliance. On the rear panel of the storage shelf, turn both power switches
to OFF to turn off the shelf.
4Verify that the appliance and the storage shelf or shelves are shut down.
The following determine if a storage shelf is turned off:

on the rear of the appliance are off.
• There is no active disk or fan noise and no airflow coming out of the rear panel.
The following determine if the appliance is shut down:
• The LED indicators on the control panel are off.
• The LED indicators for the disks on the front of the appliance are off. The LED indicators on
the rear of the appliance are off.
• There is no active disk or fan noise and no airflow coming out of the rear panel.
5Put on an ESD-compliant wrist strap or take other ESD-protective measures.
6Label and disconnect all cables, including the power cords, from the rear panel of the storage
shelf.
Warning: If the data cables are connected to the wrong ports after the repair, data can be
corrupted or lost when the appliance is turned on.
7Remove the front bezel. Grip the bezel on the sides and pull it from the storage shelf.
8Remove the ear caps from both sides of the storage shelf and unscrew the screws that hold it to
the rack. Set the caps and the screws aside in a safe location.
