This section describes the procedure for opening the chassis by removing the chassis cover.
Warning
Do not touch the power supply when the power cord is connected. For systems with a power
switch, line voltages are present within the power supply even when the power switch is OFF and
the power cord is connected. For systems without a power switch, line voltages are present within
the power supply when the power cord is connected. To see translations of the various warnings
that appear in this publication, refer to the
Regulatory Compliance and Safety Information
document that accompanied this device.
Warning
Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift
with both hands. To prevent injury, keep your back straight and lift with your legs, not your back.
To prevent damage to the chassis and components, never attempt to lift the chassis with the
handles on the power supplies or on the interface processors, or by the plastic panels on the front
of the chassis. These handles were not designed to support the weight of the chassis. To see
translations of the warnings that appear in this publication, refer to the
Regulatory Compliance
and Safety Information
document that accompanied this device.

You will need the following tools to remove and replace the chassis cover:
•
Number 2 Phillips screwdriver
