Port Logged-In LED (Green)
The Logged-in LED indicates the logged-in or initialization status of the connected
devices. After successful completion of the POST, the switch extinguishes all
Logged-In LEDs. Following a successful port login, the switch illuminates the
corresponding logged-in LED. This shows that the port is properly connected and
able to communicate with its attached devices. The Logged-In LED remains
illuminated as long as the port is initialized or logged in. If the port connection is
broken or an error occurs that disables the port, the Logged-In LED is
extinguished. Refer to
“Logged-In LED Indications” on page 4-5 for more
information about the Logged-In LED.
Port Activity LED (Green)
The Activity LED indicates that data is passing through the port. Each frame that
the port transmits or receives illuminates this LED for 50 milliseconds. This makes
it possible to observe the transmission of a single frame.
Transceivers
The SANbox 3810 switch supports SFP optical transceivers for the SFP ports. A
transceiver converts electrical signals to and from optical laser signals to transmit
and receive data. Duplex fiber optic cables plug into the SFP transceivers which
then connect to the devices. An SFP port is capable of transmitting at 1-, 2-, 4-, or
8-Gbps; however, the transceiver must also be capable of delivering at these
rates.
Port Types
SANbox 3810 switches support fabric ports (F_Port, FL_Port); generic ports
(G_Port, GL_Port) and expansion ports (E_Ports) are not available. Switches
come from the factory with all SFP ports configured as FL_Ports. Fabric ports
function as follows:
„
An FL_Port supports a loop of up to 126 devices. An FL_Port can also
configure itself during the fabric login process as an F_Port when connected
to a single device (N_Port).
„
An F_Port supports a single device.
