Version: 4.2 (05/04/2020)
Purpose
This document describes the process to replace the power cable for the Veritas 5230, 5240 and 5250
Appliances and the 2U12 Storage Shelf.
Affected appliance models
• 5230 Appliance
• 5240 Appliance
• 5250 Appliance
• Veritas 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 removing and replacing the power cable
This document describes how to replace a Veritas Appliance or Veritas 2U12 Storage Shelf power
cable while the system is powered on. Before replacing an appliance power cable, ensure that one
of the power cables to the appliance must be operating at all times. If both power cables must be
removed at the same time, the shutdown procedure must be performed on the appliance before a
power cable is removed.
Similarly before replacing a Veritas 2U12 Storage Shelf power cable, ensure that one of the power
cables to each storage shelf must be operating at all times. If both power cables must be removed
at the same time on the storage shelf, ensure that there are no I/O operations on the appliance in
progress, and then turn off the storage shelf.
This repair can be accomplished with the appliance installed in the rack.
Note: If the appliance has attached storage shelves, the storage shelves do not need to be powered
down while the appliance is being serviced.
