Grounding the Model LRA2900A

Do the following:

1.Assemble a ground wire using #10 AWG wire with green-colored insulation and two ring terminals. Make the wire long enough to reach one of the following ground sources:

–The building ground rod (generally located at the site’s main service entrance)

–A sprinkler system pipe

–A cold-water pipe

–Building structural steel

To avoid the risk of personal injury, the distance between ground and the equipment rack must not exceed the distance specified in either local electrical codes or the National Electrical Code.

2.Install the ground wire between the grounding stud (see figure 6) and the grounding source.

Connecting the Ethernet ports

The RAS has a single 10/100 Ethernet interface for connection to your LAN (see figure 7). The Ethernet port will autosense the correct speed of the local LAN and automatically negotiate half- or full-duplex operation. This section describes connecting the RAS to the Ethernet LAN via an Ethernet hub, switch, or workstation.
