Electrical Requirements
The electrical requirements for a repeater are as follows:
■ Voltage: 100 to 240 VAC
■ Frequency: 50 to 60 Hz
■ Power: 0.25 to 0.5 Amps maximum
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.
NOTE: If the supplied shielded power cord is lost or damaged, replace it with an
identical shielded power cord set to ensure emissions compliance.
Spatial Requirements
The repeater's dimensions are 1.75 x 17.00 x 8.5 inches, 4.44 x 43.18 x 21.59
centimeters (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. If this is necessary, you will need longer repeater
expansion port cables to connect the repeaters. See the “Twisted-Pair
(UTP/STP) Wire Requirements” section 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/STP) 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 LAN reliability.
