2-2Planning Repeater Installation

CAUTION: The power outlet must be a non-switched, three-pronged, grounded outlet. Do not use a three-to-two pronged adapter at the outlet. Doing so may result in electrical shock and/or damage to the repeater and will void your warranty.

NOTE: If the supplied power cord is lost or damaged, replace it with a power cord of the same type and current rating (10 A). The replacement cord should also meet required regulatory approvals to ensure emissions compliance.

Spatial Requirements

The repeater's dimensions are 3 x 16.95 x 14 inches, 7.62 x 43.05 x 35.56 cm (HxWxD).

You can interconnect two repeaters. If there is not enough space to mount the repeaters in a single rack or stack them on a single shelf, or if you want to place the repeaters in different locations, you can place them on separate shelves or in separate racks. See “Twisted-Pair (UTP) Wire Requirements” in this chapter for more information.

Be sure to allow at least 2 inches (5.1 centimeters) on each side of the repeater for proper air circulation and cable connections.

Twisted-Pair (UTP) Wire Requirements

The twisted-pair wiring you use to connect the repeater's RJ-45 ports must meet the following minimum specifications and requirements to ensure long- term reliability.

■The wiring must be unshielded twisted-pair (UTP) Category 5.

■Two pairs of the four-pair wiring are used for signalling.

■Depending on building codes, different insulation materials may be required. Plenum-rated or TEFLON-coated wiring may be required in some areas.

■The wire gauge should be between 18 and 26 AWG. (Most telephone installations use 24-gauge wiring.)
