Ethernet port LEDs
There are two LEDs built into the Ethernet port that indicate the transmission
activity over the Ethernet connection and link status.
Table 6 contains a description of Ethernet port LEDs.
LED activities and diagnostic flash patterns
Table 7 contains descriptions of the activities and corresponding diagnostic flash
patterns for the switch LEDs.
Table 6. Ethernet port LEDs
LED name LED description
Activity LED The Activity LED is lit when data is transmitted or received over

LED name LED activity/diagnostic flash pattern
OK This LED is lit at startup and remains lit while the switch is pow-
ered on.
Location This LED is lit when enabled by the Chassis Management Mod-
ule web interface or command line interface.
! (Switch Fault) This LED operates as follows:
• The LED is off during initialization or when the switch is in
normal operation.
• The LED is lit during LED test or to indicate a system fault
during a POST failure, thermal fault, or other critical switch
fault.
External port
Logged-in (LOG) This LED operates as follows:
• The LED is off when the corresponding external port is not
logged in.
• The LED is lit when the corresponding external port is logged
in or during the LED test.
• The LED pattern indicates the following conditions:
— Logged in: The LED is lit.
— Logging in: The LED flashes at 1-second intervals.
— Beacon location: The LED flashes at 1-second intervals.
— Error: The LED flashes two times per second.
— The corresponding external port is disabled: The LED
flashes at 1-second intervals.
