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 module extinguishes all Logged-In LEDs. Following a successful loop initialization or port login, the switch module 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 will flash. Refer to “Logged-In LED Indications” on page 4-2for 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 causes this LED to illuminate for 50 milliseconds. This makes it possible to observe the transmission of a single frame. When extending credits, the Activity LED for a donor port will reflect the traffic of the recipient port. Refer to “Distance” on page 2-4for more information about extended credits and donor ports.

Transceivers

Switch modules support 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 fiber optic cables plug into the transceivers which then connect to the devices. A Fibre Channel port is capable of transmitting at 1-Gbps or 2-Gbps; however, the transceiver must also be capable of delivering at these rates.

The SFP transceivers are hot pluggable. This means that you can remove or install a transceiver while the switch module is operating without harming the switch module or the transceiver. However, communication with the connected device will be interrupted. Refer to “Install SFP Transceivers” on page 3-3for information about installing and removing SFP optical transceivers.
