Safety, Environmental, and
Electronic Emissions Notices
Read the following warnings before setting up or using the appliance.
Warning - Do not block air vents. A minimum 1/2-inch clearance is
required.
Warning - This appliance does not contain any user-serviceable parts. Do
not remove any covers or attempt to gain access to the inside of the
product. Opening the device or modifying it in any way has the risk of
personal injury and will void your warranty. The following instructions are for
trained service personnel only.
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, to use a grounded wrist strap designed for static discharge elimination.
 Touch 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
short. The battery cell may heat up under these conditions and present a burn hazard.
Warning - 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.
 Disconnect the system board power supply from its power source before you connect or disconnect
cables or install or remove any system board components. Failure to do this can result in personnel
injury or equipment damage.
 Avoid short-circuiting the lithium battery; this can cause it to superheat and cause burns if touched.
 Do not operate the processor without a thermal solution. Damage to the processor can occur in
seconds.
 Class 1 Laser Product Warning
Rack Mount Instructions
The following or similar rack-mount instructions are included with the installation instructions:
1. Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration
should be given to installing the equipment in an environment compatible with the maximum ambient
temperature specified by the manufacturer.
2. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
