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

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 HP StorageWorks SN6000 Fibre Channel Switch supports SFP optical transceivers for the SFP ports
and XPAK optical transceivers or XPAK stacking cables for the XPAK 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-Gb/s; however, the transceiver must also be capable of delivering at these rates.
The SFP and XPAK transceivers are hot-pluggable. This means that you can remove or install a transceiver
while the switch is operating without harming the switch or the transceiver. However, communication with
the connected device is interrupted. For information about installing and removing SFP+ optical
transceivers, see

Port types

The SN6000 Fibre Channel Switch supports generic ports (G_Port, GL_Port), fabric ports (F_Port, FL_Port),
expansion ports (E_Port), and transparent routing ports (TR_Port). Switches come from the factory with all
