Fibre Channel ports

The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19
Each of the ports is served by a Small Form-Factor Pluggable (SFP+) transceiver and is capable of 8-Gb/s,
4-Gb/s, or 2-Gb/s transmission.
• SFPs are hot-pluggable.
• User ports can self-discover both the port type and transmission speed when connected to devices or
other switches.
• The port LEDs are located above ports 0–9 and below ports 10–19, and provide port login and activity
status information.
NOTE: Setting a Fibre Channel port that has an 8-Gb/s SFP transceiver to 1-Gb/s will down the port.

Port LEDs

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. For more information, see
