Connecting The Device To The Network; Connecting Ethernet Cables - H3C WX3820X Installation Manual

Connecting the device to the network

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 "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 "Optional transceiver modules."
The fiber ports on the device support only LC connectors.
To connect an optical fiber for a fiber port:
1. Remove the dust plug from the fiber port.
2. Pivot the bail latch of the transceiver module up so that it catches a knob on the top of the
transceiver module.
3. Holding both sides of the transceiver module, insert the transceiver module slowly into the port.
4. Identify the Rx and Tx ports on the transceiver module and remove the dust caps from the
optical fiber connectors. Use the optical fiber to connect the Rx port and Tx port on the
transceiver module to the Tx port and Rx port on the peer end, respectively.
5. Examine the port LEDs:
If the LED is on, a fiber link has been set up.

If the LED is off, the link has not been set up. The reason might be wrong connection of the

Tx and Rx ends. Swap the fiber connectors in the Tx and Rx ports at one end of the fiber.
