Chapter 3 Hardware Installation Procedures

This section describes how to install hardware for use in the hardware system, the article addresses the
following topics :
To prevent damage to any system board, it is important to handle it with care. The following measures are
generally sufficient to protect your equipment from static electricity discharge:
When handling the board, use a grounded wrist strap designed for static discharge elimination and
touches a grounded metal object before removing the board from the antistatic bag. Handle the board by its
edges only; do not touch its components, peripheral chips, memory modules or gold contacts.
When handling processor chips or memory modules, avoid touching their pins or gold edge fingers.
Restore the communications appliance system board and peripherals back into the antistatic bag when they
are not in use or not installed in the chassis.
Some circuitry on the system board can continue operating even though the power is switched off. Under
no circumstances should the Lithium battery cell used to power the real-time clock be allowed to be shorted.
The battery cell may heat up under these conditions and present a burn hazard.
1. "CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer's instructions."
2. This guide is for technically qualified personnel who have experience installing and configuring
system boards. Disconnect the system board power supply from its power source before you
connect/disconnect cables or install/remove any system board components. Failure to do this can
result in personnel injury or equipment damage.
3. Disconnect the power cord before making any installation.
4. Avoid short-circuiting the lithium battery; this can cause it to superheat and cause burns if touched.
5. Do not operate the processor without a thermal solution. Damage to the processor can occur in
seconds.
6. Do not block air vents. Minimum 1/2-inch clearance required.
