If earth is available at the installation site, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube into the earth to serve as a grounding conductor. Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.

Figure2-10 Grounding the device by burying a grounding conductor into the earth

(Optional) Installing network port lightning protectors

IMPORTANT:

· Before installing a network port lightning protector, read the instructions in the document that comes with the protector.

· Network port lightning protectors are available only for 10M/100M/1000M RJ-45 Ethernet copper ports.

· If multiple network ports have network cables routed outdoors, install a network port lightning protector for each network port.

If part of the network cable for a network port is routed outdoors, install a network port lightning protector for the port to protect against damages caused by lightning strikes.

No network port lightning protectors are provided with the device. Purchase them yourself as required.

The network port lightning protector installation procedure is the same for the WX1800H series access controllers. The following procedure uses the WX1840H access controller as an example.

To install a network port lightning protector for a network port:

1. Use a double-faced adhesive tape to stick the network port lightning protector onto the device chassis, and make sure it is as close to the grounding screw of the device as possible.

2. Cut the ground wire of the protector to a length (as short as possible) as required by the distance between the protector and the grounding screw of the device. Attach the ground wire securely to the grounding screw of the device.

Make sure the grounding screw of the device is reliably grounded.

3. Use a multimeter to verify that the ground wire of the protector makes good contact with the grounding screw of the chassis.

4. Insert the outdoor network cable into the protector's Surge end, and insert the cable from the network port into the Protect end.

5. Examine the port LED to verify that the port is operating correctly.

Connecting a fiber port

WARNING!

Disconnected optical fibers or connectors might emit invisible laser light. Do not stare into beams or view directly with optical instruments when the switch is operating.

CAUTION:

· To connect a fiber port by using an optical fiber, first install a transceiver module in the port and then connect the optical fiber to the transceiver module.

· Insert a dust cap into any open optical fiber connector and a dust plug into any open fiber port or transceiver module port to protect them from contamination and ESD damage.

· Never bend an optical fiber excessively. The bend radius of an optical fiber must be not less than 100 mm (3.94 in).

· Keep the fiber end clean.

· Make sure the Tx and Rx ports on a transceiver module are connected to the Rx and Tx ports on the peer end, respectively.

Only the WX1840H access controller provides fiber ports.

No transceiver modules are provided with the device. Purchase transceiver modules yourself as required. For transceiver module specifications, see "Appendix A Chassis views and technical specifications."
