Fibre Channel ports

The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19 (Figure 3).

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.

Figure 3 Fibre Channel ports

The 8/20q Fibre Channel Switch comes from the factory as an 8- or 16-port switch, enabling ports 0–7 or

0–15 respectively. You can enable additional ports up to the 20-port maximum using the HP StorageWorks

8/20q 4-port Upgrade License. For more information, see ”Installing feature license keys” on page 40.

Port LEDs

Each port has its own Logged-in LED (green) and Activity LED (green) (Figure 4).

Figure 4 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 ”Logged-in LED indications” on page 44.

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.
