Ethernet Ports
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable.
When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thereby requiring you to make sure that the settings of the peer Ethernet port are the same in order to connect.
Default Ethernet Negotiation Settings
The factory default negotiation settings for the ports on the Switch are:
• Speed: Auto
• Duplex: Auto
• Flow control: Off
LEDs
After you connect the power to the Switch, view the LEDs to ensure proper functioning of the Switch and as an aid in troubleshooting.

PoE Usage MAX
Bar1 is the bar at the bottom; bar 5 is the bar at the top.
Green
(Bar1 – Bar3)
On
Each bar represents 20 percent of PoE Power consumption.
Bar 1: PoE power usage is below 20 percent of the power supplied budget.
Bar 2: PoE power usage is below 40 percent of the power supplied budget, but over 20 percent of the power supplied budget.
Bar 3: PoE power usage is below 60 percent of the power supplied budget, but over 40 percent of the power supplied budget.
Yellow
(Bar4)
On
PoE power usage is below 80 percent of the power supplied budget, but over 60 percent of the power supplied budget.
Red
(Bar5)
On
PoE power usage is more than 80 percent of the power supplied budget.
Blinking
Less than 5 percent of the power supplied budget remains. 5 percent is the default value.
 
Off
