Connecting interface cables
Connect cables to the interfaces on the router before powering on the router.
The following uses an Ethernet copper port and an Ethernet fiber port as examples to describe the
cable connection procedures.
Connecting an Ethernet copper cable
Connect one end of the cable to the Ethernet copper port on the router. Connect the other end
1.
of the cable to the Ethernet copper port on the peer device.
The fixed ports on the router are MDI/MDIX autosensing. You can use straight-through or
crossover network cables to connect the ports.
Examine the port LED on the router.

Connecting an Ethernet optical fiber
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:
• Make sure the bend radius of the fiber is not less than 10 cm (3.94 in).
• Make sure the end faces of the fiber connectors are clean.
• Insert a dust plug into any open fiber port to protect them from contamination.
To connect an Ethernet optical fiber:
Remove the dust plug from the Ethernet fiber port.

Identify the upside and downside of the transceiver module and then insert the transceiver
2.
module into the fiber port.
Identify the Rx and Tx ports on the transceiver module. Use the optical fiber to connect the Rx
3.
port and Tx port on the transceiver module to the Tx port and Rx port on the peer end,
respectively.
Examine the port LED on the router.
