2-5

Mounting the router on a workbench

IMPORTANT:

mount the router on a workbench, follow these guidelines:

•

Make sure the workbench is clean, stable, and reliably grounded.

•

Enable a minimum clearance of 100 mm (3.94 in) around the chassis for heat dissipation.

•Do not place heavy objects on the router.

To mount the router on a workbench:

1. Place the router upside down on the workbench.

2. Attach the rubber feet to the four round holes in the chassis bottom.

3. Place the router on the workbench with the top panel facing up.

Figure2-7 Mounting the router on a workbench

Grounding the router

CAUTION:

•

Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.

Before using the router, make sure the router is reliably grounded.

•

Connect the grounding cable to the grounding system in the equipment room. Do not connect it

to a fire main or lightning rod.

Grounding method for rack mounting

CAUTION:

The grounding p

oint on the rack must be connected securely to a grounding strip in the equipment

room.

To ground the router when it is mounted in a rack:

1. Remove the grounding screw from the grounding point on the router.

2. Use the grounding screw to attach the ring terminal (M4) of the grounding cable to the

grounding point on the router.

3. Connect the ring terminal (M8) at the other end of the grounding cable to the grounding point on

the rack.

2-6

Figure2-8 Grounding the router when it is mounted in a rack

Grounding method for workbench mounting

To ground the router when it is mounted on a workbench:

1. Remove the grounding screw from the grounding point on the router.

2. Use the grounding screw to attach the ring terminal (M4) of the grounding cable to the

grounding point on the router.

3. Connect the ring terminal (M8) at the other end of the grounding cable to a grounding strip.

Figure2-9 Grounding the router when it is mounted on the workbench

2-7

Connecting interface cables

Connecting an Ethernet cable to a copper port

1. Connect one end of the Ethernet cable to the copper port on the router. Connect the other end

of the cable to the copper port on the peer device.

The copper ports on the router are MDI/MDIX autosensing.

2. Examine the port LED on the router to verify that the cable is connected correctly. For more

information about the LEDs, see "Appendix B LEDs."

Connecting an optical fiber to a fiber port

WARNING

Disconnected optical fibers or transceiver

modules might emit invisible laser light. Do not stare into

beams or view directly with optical instruments when the router is operating.

CAUTION:

•

Never bend or curve a fiber excessively. The bend radius of a fiber must be not less than 100 mm

(3.94 in).

•

Keep the fiber end clean.

•

Before connecting an optical fiber to a fiber port, make sure the fiber connector matches the

transceiver module in the fiber port.

•

To avoid damage to a transceiver module, make sure the received optical power does not

exceed

the maximum allowed receive power of the transceiver module.

•

To connect an optical fiber to a fiber port, first install the transceiver module in the fiber

port and

then connect the optical fiber to the transceiver module. Do not connect an optical fiber d

irectly to

a fiber port.

•

If you are not to use a fiber port or transceiver module, insert dust plugs into the

port or module. If

you are not to connect an optical fiber, install dust caps for the fiber connector.

To connect an optical fiber to a fiber port:

1. Remove the dust plug from the fiber port.

2. Install a transceiver module.

Pull the bail latch on the transceiver module upwards to catch the knob on the top of the

transceiver module. Take the transceiver module by its two sides and push the end without the

bail latch gently into the port until it snaps into place.

3. Remove the dust cap from the optical fiber connector, and use dust free paper and absolute

alcohol to clean the end face of the fiber connector.

4. Identify the Rx and Tx ports on the transceiver module. Plug one end of the optical fiber into the

transceiver module, and plug the other end into the transceiver module in the peer device.

Make sure the Rx port and the Tx port are connected to the Tx port and the Rx port on the peer

device, respectively.

5. Examine the port LED on the device to verify that the optical fiber is connected correctly. For

more information, see "Appendix B LEDs."

2-8

Figure2-10 Connecting an optical fiber to a fiber port

Connecting power cords

CAUTION:

Before connecting a power cord, make sure the router is reliably grounded.

To connect a power cord:

1. Connect the DC power cord connector to the DC input receptacle on the router.

2. Fasten the screws on the connector to secure the connector to the receptacle.

3. Connect the other end of the DC power cord to the wiring terminals of a DC power source, with

the negative wire (–) to the negative terminal (–) and the positive wire (+) to the positive terminal

(+)..

Figure2-11 Connecting the DC power cord

Verifying the installation

After you complete the installation, verify the following requirements are met:

•

There is enough space for heat dissipation around the router.

•

The router is installed securely.

•

All screws are fastened tightly.

2-9

•

The grounding cable and power cord are securely connected.

•

The power source meets the power specifications of the device.

Accessing the router

Using a console cable to connect the router to a configuration

terminal

Setting up the configuration environment

IMPORTANT:

hen you connect a PC to a powered-on router, first connect the DB-9 connector of the console

cable to the PC, and then connect the RJ-45 connector to the router.

To connect a configuration terminal to the router by using a console cable:

1. Select a configuration terminal, which can be a character terminal with an RS-232 serial port, or

a PC.

2. Plug the DB-9 female connector of the console cable into the serial port on the configuration

terminal and the RJ-45 connector into the console port on the router.

Setting terminal parameters

To configure and manage the router through the console port, you must run a terminal emulator

program, TeraTermPro or PuTTY, on your configuration terminal. You can use the emulator program

to connect a network device, a Telnet site, or an SSH site. 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.

Powering on the router

WARNING

Locate the power switch

of the power supply system before powering on the router so you can

quickly shut power off when an electrical accident occurs.

To power on the router:

1. Power on the router

2. Verify the following items:

The LEDs on the front panel are normal. For the LED description, see "Appendix B LEDs."

The configuration terminal displays information normally.
