FaxPress Premier Administrator Guide 557
The telephone company may make changes in its facilities, equipment, operations or pro-
cedures that could affect the proper functioning of your equipment. If they do, you will be
notified in advance in order for you to make necessary modifications to maintain uninter-
rupted service.
Electrical Safety Advisory
We recommend the installation of an AC surge arrestor in the AC outlet to which this equip-
ment is connected. Telephone companies report that electrical surges, typically lighting
transients, are very destructive to customer terminal equipment connected to AC power
sources.
Any replacement of fuses should only be done by service personnel.
Proper AC source grounding, and grounding circuit continuity are vital for safe operation
Use only the 3-wire, 3-terminal power cord provided for the FaxPress Premier units.
To preclude the possibility of electrical shock, do not ever remove the FaxPress Premier chassis.
Safety Warning Messages
To prevent damage to the FaxPress Premier system board, it must be handled with care.
The following measures are generally sufficient to protect your equipment from static elec-
tricity discharge:
„
When handling the system board, use a grounded wrist strap designed for
static discharge elimination and touch a grounded metal object before remov-
ing 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 golden edge fingers. Put the value communications appliance sys-
tem board and peripherals back into the antistatic bag when 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 coin cell used to power the real-
time clock be allowed to be shorted. The coin cell can heat under these conditions and
present a burn hazard.
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.
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.
Rack Mounting Safety Considerations
When rack mounting a FaxPress Premier unit, consider the following:
„
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 rack ambient temperature of 50
degrees Celsius.
„
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.
