Warnings
Read and adhere to all warnings, cautions, and notices in this guide and
the documentation supplied with the chassis, power supply, and accessory
modules. If the instructions for the chassis and power supply are inconsistent
with these instructions or the instructions for accessory modules, contact
the supplier to find out how you can ensure that your computer meets
safety and regulatory requirements.
Cautions
Electrostatic discharge (ESD) can damage system components. Do the de-
scribed procedures only at an ESD workstation. If no such station is avail-
able, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the computer chassis.
Safety Information
Before installing and using the device, note the following precautions:
▪
Read all instructions carefully.
▪
Do not place the unit on an unstable surface, cart, or stand.
▪
Follow all warnings and cautions in this manual.
▪
When replacing parts, ensure that your service technician uses parts spec-
ified by the manufacturer.
▪
Avoid using the system near water, in direct sunlight, or near a heating
device.
▪
The load of the system unit does not solely rely for support from the
rackmounts located on the sides. Firm support from the bottom is highly
necessary in order to provide balance stability.
The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer. Dis-
card used batteries according to the manufacturer’s instructions.
Installation Recommendations
Ensure you have a stable, clean working environment. Dust and dirt can get
into components and cause a malfunction. Use containers to keep small
components separated.
Adequate lighting and proper tools can prevent you from accidentally dam-
aging the internal components. Most of the procedures that follow require
only a few simple tools, including the following:
• A Philips screwdriver
• A flat-tipped screwdriver
• A grounding strap
• An anti-static pad
Using your fingers can disconnect most of the connections. It is recom-
mended that you do not use needlenose pliers to disconnect connections as
these can damage the soft metal or plastic parts of the connectors.
