1.1 For Your Safety
by placing the product on a bed, sofa, rug, or other similar surface while in use. The product should never
be placed near or over a radiator or other heat source. This product should not be placed in a sealed
environment unless proper ventilation is provided.
•
Make sure that the surface behind the PBX is flat and free of obstacles, so that the openings on the back
of the PBX will not be blocked.
•
Make sure that the surface behind the PBX is not made of wood.
•
When this product is no longer in use, make sure to detach it from the rack or wall.
•
Use only the AC power cord included with the PBX.
•
When the PBX is mounted on a 19-inch rack, make sure that the installation of the unit does not cause the
temperature of the rack to exceed its limit.
•
Make sure to install all necessary optional service cards in the PBX before performing the wall mounting
procedure. If it is necessary to install or remove a card, make sure to detach the PBX from the wall before
installing or removing the card.
•
When driving the screws into the wall, be careful to avoid touching any metal laths, wire laths or plates in
the wall.
•
When placing the PBX onto the wall, make sure that the arrows on the metal brackets are pointing upward.
If the arrows are not pointing upward, the PBX may fall, resulting in injury.
•
When opening the top cover, the power switch must be turned off.
•
For safety reasons, close the top cover and tighten the screws before operating the PBX.
•
If the PBX is not installed properly using the securing correct methods, the PBX may fall causing serious
damage.
•
When the PBX is placed on a desktop, make sure that the PBX is placed as indicated in "4.2.10 Placing
the PBX on a Desktop". Do not place it on its side or upside down.
•
Performing surge protection is essential. Make sure to follow the instructions in "4.2.12 Surge Protector
Installation".
•
It is strongly recommended to use SSL encrypted communication when the PC is accessing the PBX via
the Internet. To use SSL encryption, routers must have a port set up for https communication.
•
To prevent data leakage, render the Storage Memory Card physically unusable before disposal.
•
Avoid using the same AC outlet for computers and other office equipment, as noise generated by such
equipment may hamper system performance or interrupt the system.
•
Unplug the system from its power source when wiring, and plug the system back in only after all wiring is
completed.
•
Trunks should be installed with surge protectors. For details, refer to "4.2.12 Surge Protector
Installation".
•
When installing or removing the Storage Memory Card, the power switch must be turned off.
•
When installing or removing the optional service cards, the power switch must be turned off.
•
For earthing wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm
•
When connecting a SLC2/BRI4, SLC2/PRI30 or SLC2/PRI23 card to the trunk, connect through an NT1;
do not connect to the U interface of the trunk directly.
•
PRI ports of SLC2/PRI30 and SLC2/PRI23 cards are SELV ports and should only be connected to SELV
services.
•
The MOH port and Pager port are SELV ports and should only be connected to approved SELV devices,
or in Australia, via a Line Isolation Unit with a Telecommunications Compliance Label.
•
To protect the system, keep the following in mind:
a.
Make sure that both connector cases (frame ground) of the RS-232C cross cable (shielded cable) are
conductive. If they are not conductive, make sure that both connector cases of the cable are firmly
connected.
b.
If this is not possible, connect the frame of the PBX to the frame of the PC/Printer using an earthing
wire in order to prevent difference in the electrical potentials.
