Warnings
Only
trained and qualified personnel should be allowed to install, replace, or service this equipment.
Heed safety instructions:
Before working with your server product, whether you are using this guide or any other resource as a
reference, pay close attention to the safety instructions. You must adhere to the assembly instructions in this guide to ensure and
maintain compliance with existing product certifications and approvals. Use only the described, regulated components specified in
this guide. Use of other products/components will void the UL listing and other regulatory approvals of the product and will most
likely result in noncompliance 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 the system, you must
unplug the AC power cord from the wall outlet. Make sure the AC power cord is unplugged before you open the chassis, add, or
remove any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power, telephone, and
communication 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 disk drives, boards, and other parts. We recommend that you
perform all procedures in this chapter only at an ESD workstation. If one is not available, provide some ESD protection by wearing
an antistatic wrist strap attached to chassis ground - any unpainted metal surface - on your server when handling parts.
ESD and handling boards:
Always handle boards carefully. They can be extremely sensitive to 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 jumpers have
a small tab on top that you can grip with your fingertips or with a pair of fine needles nosed pliers. If your 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 with the pliers,
never the wide sides. Gripping the wide sides can damage the contacts inside the jumper, causing intermittent problems with the
function controlled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper, or
you may bend or break the pins on the board.
Ground plug:
Users shall not remove the ground pin of a power cord. This ground plug is a protective earthing used as a
SAFEGUARD, as a means via a power cord to a socket-outlet with earthing connection.
RAL:
Use only in Restricted Access Location.
Battery:
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
equipment manufacturer. Discard used batteries according to manufacturers’ instructions.
