I/O Blade LEDs
The I/O blade LEDs are as follows:
I/O Blade Good LED (Green)–This LED illuminates to indicate that the
I/O blade is operational.
I/O Blade Power LED (Green)–This LED illuminates to indicate that the
I/O blade is receiving power.
I/O Blade Fault LED (Amber)–This LED illuminates to indicate that the
I/O blade has a fatal error. This LED and the Chassis Fault LED illuminate
together.
I/O Blade Error Code LED (Green)–This LED is reserved for future use.
I/O Blade Beacon LED (White)–This LED illuminates in response to a
command issued from the management workstation to help locate an
I/O blade.
I/O Blade Hotswap LED (Blue)–This LED illuminates to indicate the I/O
blade insertion status. Continuous illumination indicates that the I/O blade is
not fully seated.
FC Port LEDs
The FC Port LEDs are as follows:
Logged-in LED (Green)–This LED illuminates to indicate 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 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 extinguish. Refer to “FC Port Diagnostics”
on page 4-8 for more information about the Logged-In LED.
Activity LED (Green)–This LED illuminates to indicate 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 2-3 for more information about extended credits and donor ports.
