Important Safety Instructions
Read all caution and safety statements in this document before
performing any of the instructions.
Warnings
Heed safety instructions:
Before working with the server,
whether using this manual or any other resource as a refer-
ence, pay close attention to the safety instructions. Adhere to
the assembly instructions in this manual to ensure and maintain
compliance with existing product certifications and approvals.
Use only the described, regulated components specified in this
manual. Use of other products / components will void the UL
listing and other regulatory approvals of the product and will
most likely result in non-compliance with product regulations in
the region(s) in which the product is sold.
System power on/off:
The power button DOES NOT turn off
the system AC power. To remove power from system, you must
unplug the AC power cord from the wall outlet. Make sure the
AC power cord is unplugged before opening the chassis, add-
ing, or removing any components.
Hazardous conditions, devices and cables:
Hazardous elec-
trical conditions may be present on power, telephone, and com-
munication cables. Turn off the server and disconnect the
power cord, telecommunications systems, networks, and
modems attached to the server before opening it. Otherwise,
personal injury or equipment damage can result.
Electrostatic discharge (ESD) and ESD protection:
ESD can
damage drives, boards, and other parts. We recommend that
you perform all procedures in this chapter only at an ESD work-
station. If one is not available, provide some ESD protection by
wearing an antistatic wrist strap attached to chassis ground any
unpainted metal surface on the server when handling parts.
ESD and handling boards:
Always handle boards carefully.
They can be extremely sensitive to electrostatic discharge
(ESD). Hold boards only by their edges. After removing a board
from its protective wrapper or from the server, place the board
component side up on a grounded, static free surface. Use a
conductive foam pad if available but not the board wrapper. Do
not slide board over any surface.
Installing or removing jumpers
: A jumper is a small plastic
encased conductor that slips over two jumper pins. Some jump-
ers have a small tab on top that can be gripped with fingertips
or with a pair of fine needle nosed pliers. If the jumpers do not
have such a tab, take care when using needle nosed pliers to
remove or install a jumper; grip the narrow sides of the jumper
