Figure 2-5. Port LEDs
2.2.1.1
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 loop initialization or 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
will flash. Refer to
“Logged-In LED Indications” on page 5-8
for more information
about the Logged-In LED.
2.2.1.2
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 3-4
for more information about
extended credits and donor ports.
