Installation Requirements To help ensure a correct installation, read this section to determine the environmental, electrical, spatial, and cable requirements.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-2 Planning 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 new wiring should conform to national and local electrical wiring code requirements and meet the above specifications. When installing wire, it is a good idea to install extra pairs of wire for future expansion.

Mounting the Repeater You can place the repeater on a level surface (table top or shelf, for example) or mount it in a standard EIA 19-inch rack.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-2 Installing the Repeater 1. Remove the two screws from the left and right side of the repeater. (These screws are extras and are not needed to install the mounting brackets.) 2. Position the bracket as shown in Figure 3-1, and secure it with the smaller bracket screws. Then attach the remaining bracket to the other side of the repeater. Bracket Screws 21 22 23 24 9 10 11 12 MDI MDI-X Figure 3-1. Attaching the Mounting Brackets 3.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-3 Connecting Twisted-Pair Cable Each RJ-45 port on the repeater can accept a standard 8-wire twisted-pair (UTP) cable that ends with an RJ-45 connector. These ports can support cable lengths up to 328 feet (100 meters). To attach twisted-pair cable, plug one of the RJ-45 connectors into the selected port on the repeater. Connect the other RJ-45 connector into a 100Base-TX or 10Base-T workstation.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-4 Installing the Repeater The default setting for the uplink switches is MDI-X (Media Dependent Interface-Reversed, that is, a standard IN repeater port). To convert Port 1 or Port 12 to an uplinkable OUT port, use a small, slotted screwdriver, or a similar tool, to set the switch to the MDI position (Figure 34). NOTE: IEEE specifications allow only one 100 Mb/s uplink connection per collision domain.

Connecting the Power Cable WARNING: The repeater has no power switch. Connecting the repeater to the power source via the power cable’s three-pronged plug powers up the repeater 2. Insert the three-pronged plug on the power cable into a non-switched, grounded power outlet on a wall, a power strip, or a grounded extension cord.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-7 Disconnecting Power To power down the repeater, disconnect the power cord from the nonswitched, grounded power outlet on the wall, power strip, or grounded extension cord. The power cord is not a TUV-tested disconnect. Therefore do not power down the repeater by disconnecting the power cord connector from the back of the repeater. Replacing the Power Supply The power supply's modular design makes the supply easy to replace.
