SFP, SFP+,QSFP+, and QSFP28 port LED state indicators
This section describes the transceiver port LED state indicators by color and fluctuation cues.
SFP, SFP+ port LED state indicators
These ports use the LED on the left side of the port (
Link/Act
) to indicate whether or not the link is
established and if a transceiver is present and active.

Description
Link/Act
Off
There is no transceiver present and the port is
administratively enabled.
Amber (blinking)
The port received a remote fault indicator (RFI).
Amber (steady)
The port is actively transmitting, but there is no link. This
indicates a local fault.
Green (steady)
The port has established a link.
Green (blinking)
The port has established a link and there is data activity.
Green (slow blinking)
The port is administratively disabled.

Green (blinking)
Operating at 1Gbps link speed
Green (Solid)
Operating at 10Gbps link speed
QSFP+, QSFP28 port LED state indicators
The QSFP+/QSFP28 used in the system includes one bi-colored (amber/green) LED per port. The
bi-colored LED is located in the transceiver cage. The bi-colored LED is labeled as “Link/Act”. The
following table defines the operation of the QSFP+/QSFP28 LEDs:
Note:
40Gbps Ethernet interfaces offer QSFP+ ports and 100Gbps Ethernet interfaces offer
QSFP28 ports.
