Connecting Ethernet cables
Connecting a copper Ethernet port
1. Connect one end of the Ethernet cable to the copper Ethernet port of the device, and the other
end to the Ethernet port of the peer device.
2. After powering on the device, examine the LEDs of the fixed copper Ethernet 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 o
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.
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."
The fiber p
orts 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. 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.
