(Optional) Installing network port lightning protectors

	CAUTION: 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.

 

	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 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.

 

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

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 grounded reliably.

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 marked IN, and insert the cable from the network port into the Protect end marked OUT.

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

Figure1-9 Installing a lightning protector for a network port

 

(Optional) Installing a surge protected power strip

	CAUTION: If you use an AC power line routed from outdoors for the device, use a surge protected power strip for the device to protect against damages caused by lightning strikes.

 

	IMPORTANT: Before installing a surge protected power strip, read the instructions in the document that comes with the strip.

 

No surge protected power strip is provided with the device. Purchase one yourself as required.

To use a surge protected power strip, first connect the AC power line routed from outdoors to the strip and then connect the power cord from the device to the strip.

You can attach the surge protected power strip to the rack, workbench, or wall of the equipment room.

Connecting the device to the network

Connecting the console cable and setting terminal parameters

To configure and manage the device through the console port, you must run a terminal emulator program, TeraTermPro or PuTTY, on your configuration terminal. For more information about the terminal emulator programs, see the user guides for these programs

The following are the required terminal settings:

·     Bits per second—9600.

·     Data bits—8.

·     Stop bits—1.

·     Parity—None.

·     Flow control—None.

Connecting Ethernet cables

Connecting an Ethernet copper port

1.     Connect one end of the Ethernet cable to the Ethernet copper port on the device, and the other end to the Ethernet port on the peer device.

2.     After powering on the device, examine the LEDs of the fixed Ethernet copper port.

For more information about the LED description, see "Appendix B  LEDs."

Connecting a fiber port

	WARNING! Do not stare into any open apertures of operating transceiver modules or optical fiber connectors. The laser light emitted from these apertures might hurt your eyes.

 

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 10 cm (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.

 

No transceiver modules are provided with the device. Purchase transceiver modules yourself as required. For more information about the transceiver modules, see "Appendix C  Optional transceiver modules."

The fiber ports on the device support only LC connectors.

To connect an optical fiber for a fiber port:
