Description
This LED will light green after powering the Switch on to indicate the ready state of
the device. The indicator is off when the Switch is no longer receiving power (i.e.
powered off).
This LED will light green if the Redundant Power Supply (RPS) is in use. If the
indicator is off, the RPS is not in use.
This LED will blink green during the Power-On Self Test (POST). When the POST is
finished, the LED will turn off. The indicator will light steady green when a user is
logged in through the console port.
This LED will light green after the diagnostics have passed with no errors. This LED is
steady red when any of the fans fail.
The Switch has LED indicators for Link and Activity.
Copper Ports: The LED will light steady green when there is a secure connection (or
link) to a 1000Mbps Ethernet device or steady orange when there is a secure
connection (or link) to a 10/100Mbps Ethernet device at any of the copper ports. The
LED will blink green when a 1000Mbps port is active or blink orange when a
10/100Mbps port is active. The LED remains off when there is no link or activity.
SFP Ports: The LED will light steady green when there is a secure connection (or
link) to a 1000Mbps Ethernet device at any of the SFP ports. The LED remains off
when there is no link or activity.
SFP+ Ports: The LED will light steady green when there is a secure connection (or
link) to a 10Gbps Ethernet device or steady orange when there is a secure connection
(or link) to a 1Gbps Ethernet device at any of the SFP+ ports. The LED will blink
green when a 10Gbps port is active or blink orange when a 1Gbps port is active. The
LED remains off when there is no link or activity.
When this light is on with a solid green light, it means that the corresponding ports are
feeding power to the PoE devices plugged in. When this light is on with a solid orange
light, it means that the port is in an error condition state. When this light is off, it
means that the ports are not supplying power to the devices plugged into the ports.
