Installation 12

Placement Considerations

Avoid placing any Syn248 component too close to the following:

 Communication devices, such as television sets, DVD players, or other cordless

telephones

 Excessive heat sources

 Noise sources, such as a window with traffic outside, motors, microwave ovens,

refrigerators, or fluorescent lighting

 Excessive dust sources, such as a workshop or garage

 Excessive moisture

 Extremely low temperature

 Mechanical vibration or shock, such as on top of the washing machine or

workbench.

Power Considerations

Ensure that there is an electrical outlet not controlled by a wall switch within 6 feet

(1.83 m) of each device location.

SB35020 Desksets are also compatible with Power over Ethernet (PoE). To use PoE, your

network needs a switch that provides PoE. Using PoE simplifies your installation by

eliminating the need to route separate power cords. It also allows you to protect your

system from power outages by connecting an Uninterruptible Power Supply (UPS) to your

PoE switch and Gateway(s). For power requirement specifications, see “Appendix C:

Technical Specifications” on page 105.

Other Preparations

Before installing the Gateway and Desksets, the following preparations may need to be

taken:

 All telephone lines must be gathered into one access point situated no more

than 9 feet (2.74 m) from the Gateway location. If rewiring is required, contact

your telephone service provider and request the help of a qualified technician.

 You may need one or more network switches set up to ensure there are sufficient

ports available for other devices in the network (such as a DSL modem).

 If you plan to use the emergency bypass feature on the Gateway, you will need

an analog phone.

 An Ethernet Port must be available within 9 feet (2.74 m) of each Deskset

location. Each Deskset is capable of sharing an Ethernet port with a PC. If one

Ethernet port already exists at a workstation, another port is not necessary

unless you need a GigE Ethernet frame rate. If this is the case, use a separate

Ethernet connection for the Deskset and the computer.
