•

Temperature Control, page 2-2

V e ntilation for Wall Mounting, page 2-2

V e ntilation for Desktop Mounting, page 2-2

Temperature Control

The installation area (room, closet, or cabinet) for the voice gateway chassis must be well ventilated and

provide adequate air circulation to ensure proper cooling. The room temperature should be maintained

between 32 to 122 degrees F (0 to 50 degrees C).

Ventilation for Wall Mounting

If you install the chassis onto a wall, ensure that there is plenty of space on all sides of the chassis to

allow adequate airflow through the chassis.

Ventilation for Desktop Mounting

If you place the chassis on a desk or shelf, do not stack other equipment or paper on top of it. Provide

plenty of space for air circulation on all four sides of the chassis.

Distance Limitations for Interface Cables

When planning your installation, consider distance limitations and potential electromagnetic

interference (EMI) as defined by the Electronic Industries Association (EIA).

Distance Limitations for Interface Cables

•

FXS Analog V o ice Port Maximum Distance, page 2-3

Interference Considerations, page 2-3

Fast Ethernet Maximum Distance

The maximum segment distance for Fast Ethernet is 330 feet (100 meters) (specified in IEEE 802.3).

FXS Analog Voice Port Maximum Distance

The maximum distance is established by a total allowable loop resistance, including the phone or

terminal equipment, of 600 Ohm.

Interference Considerations

When you run cables for any significant distance in an electromagnetic field, interference can occur

between the electromagnetic field and the signals on the cables. This has two implications for the

installation of terminal plant cabling:

•

Unshielded plant cabling can emit radio interference.

Strong electromagnetic interference (EMI), especially caused by lightning or radio transmitters, can

destroy the EIA/TIA-232 drivers and receivers in the Cisco VG202, Cisco VG202XM,

Cisco VG204, or Cisco VG204XM voice gateways.

If you use twisted-pair cables with a good distribution of grounding conductors in your plant cabling,

emitted radio interference is unlikely.

If your cables exceed the recommended distances, or if your cables pass between buildings, you must

give special consideration to the effect of lightning strikes or ground loops. If your site has these

characteristics, consult experts in lightning suppression and shielding. The electromagnetic pulse caused

by lightning or other high-energy phenomena can easily couple enough energy into unshielded

conductors to destroy electronic devices.

Most data centers cannot resolve the infrequent but potentially catastrophic problems of EMI without

using pulse meters and other special equipment. Take precautions to avoid these problems by providing

a properly grounded and shielded environment and by installing electrical surge suppression.

If you remove any module, you must either install a module in its place or install a cover plate over the

opening. To prevent electromagnetic interference, all module openings must be either occupied or

covered.

For advice on the prevention of electromagnetic interference, consult experts in radio-frequency

interference (RFI).
