Input Power LED (Green)
The Input Power LED indicates the voltage status at the switch logic circuitry. This
LED illuminates when the switch logic circuitry is receiving the proper DC
voltages.

Fibre Channel Ports
Each SANbox2-16 switch has 16 Fibre Channel ports numbered 0 - 15 as shown
in Figure 2-4. Each of these ports is served by a Small Form-Factor Pluggable
(SFP) transceiver. The port LEDs are located to the right of their respective ports
and provide port login and activity status information. Port modes configure the
ports to communicate with public devices, private devices, and inter-switch
connections.

Small Form-Factor Pluggable (SFP) Transceivers
An SFP transceiver, like the one shown in Figure 2-5, converts electrical signals to
and from optical laser signals to transmit and receive data. SFP transceivers plug
into the ports; duplex fiber optic cables plug into the transceivers which then
connect to the devices. A port is capable of transmitting at 1 Gbps or 2 Gbps;
however, the transceiver must be capable of 2 Gbps for the port to deliver at that
rate.
The SFP transceivers are hot swappable. This means that you can remove or
install an SFP transceiver while the switch is operating without harming the switch
or the transceiver. However, communication with the connected device will be
interrupted. Refer to Section 6 Removal/Replacement for information about
installing and removing SFP optical transceivers.
