Removing and Replacing a Power Supply 1
Removing and Replacing a Power
Supply
This document describes replacement procedures for the power supply customer
replaceable unit (CRU) installed in the Sun Storage J4200 array disk tray. This
document assumes you have:
■Identified the tray containing the failed power supply.
■Received the replacement power supply.
This product is intended for restricted access whereby access is controlled through
the use of a means of security (e.g., key, lock, tool, badge access), and personnel
authorized for access have been instructed on the reasons for the restrictions and any
precautions that need to be taken.
ESD Precautions
When performing this service action, observe the following electrostatic discharge
(ESD) precautions:
■Remove all plastic, vinyl, and foam material from the work area.
■Wear an antistatic wrist strip at all times when handling any CRU.
■Before handling any CRU, discharge any static electricity by touching a grounded
surface.
■Do not remove a CRU from its antistatic protective bag until you are ready to
install it.
■After removing a CRU from the cabinet, immediately place it in an antistatic bag
or antistatic packaging.
■Handle any card CRU only by its edges and avoid touching the components or
circuitry.

■Do not slide a CRU over any surface.
■Limit body movement (which builds up static electricity) during the removal and
replacement of a CRU.
Power Supply Components
Each tray contains two hot-swappable, redundant power supplies. If one power
supply is turned off or malfunctions, the other power supply maintains electrical
power to the tray.
