Fibre Channel Transceivers

The SANbox 6140 router supports SFP optical transceivers for the Fibre Channel ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fibre optic cables plug into the transceivers, which then connect to the devices. A 1-Gbps/2-Gbps Fibre Channel port can transmit at 1-Gbps or 2-Gbps; however, the transceiver must also be capable of delivering these rates.

The SFP transceivers are hot pluggable. You can remove or install a transceiver while the router is operating without harming the router or the transceiver. However, this interrupts communication with the connected device. See page 4-4for information about installing and removing SFP optical transceivers.
