Radiance 1Gbps Interface Line Cards with SFP Optics 11
For more detailed information about the optics, refer to the Technical
Specifications.
IMPORTANT: The Radiance 1Gbps interface line card is designed to
operate using only the Metrobility SFP transceivers listed in this
document. Installing unspecified parts may damage the product and
will void the unit’s warranty.
When making fiber optic connections, make sure that the optical
transmitter on the Radiance line card connects to the optical receiver on
the connected device, and that the optical transmitter on the device
connects to the optical receiver on the Radiance line card.
Use the link (LK) LEDs on the front panel of the card to verify correct
segment connectivity. As you insert the cable into each port, the LK
LED will be lit if the following conditions are met:
• Power is being applied to the chassis.
• There is an active device connected to the other end of the
cable, and it is sending idle link signals.
• All connections are secure and the cables are undamaged.
• Both ends of the cable are set to the same auto-negotiation
state. To maximize device compatibility, the Radiance line
card is shipped with auto-negotiation enabled on both ports. If
necessary, disable auto-negotiation and set full duplex on the
fiber port of the remote device to establish link.
For information on replacing the SFP transceiver, refer to Changing the
SFP Optics.
