Power Over Ethernet (PoE)
The switch provides the PoE on the eight Ethernet ports shown in
. PoE provides the ability to detect attached Powered Devices (PDs), and deliver power to the PD via
Ethernet cabling. The switch is fully compliant with the IEEE 802.3af PoE and IEEE 802.3at PoE+ standards. By default, the PoE switch discovers and provides power to IEEE-
compliant PDs, it also supports legacy PDs. The total PoE budget for the switch is 65W. Each port can provide a maximum of 30W in compliance to the IEEE 802.3at PoE+
standard. All eight ports cannot have 30W PD devices as this exceeds the PoE budget of the switch; a combination of few 30W PDs and low power PDs can be used as long as
the sum of load is less than 65W.
Understanding the Status LEDs
The LEDs on the front panel provide you with switch status checking and monitoring. The following section describes the three types of LEDs.
SYSTEM Status LED
The SYSTEM Status LED indicates if the switch is powered up correctly or if a system alarm has been triggered for troubleshooting.
LINK/ACT/SPD Mode LED
The LINK/ACT/SPD Mode LED indicates the port status LEDs are displaying in link/act/speed mode.
PoE Mode LED
The PoE Mode LED indicates the port status LEDs are displaying in PoE mode.
Port Status LEDs
The Port Status LEDs indicate the current status of each port in either Link/Act/Speed mode or PoE mode. By pressing the
MODE
button for less than two seconds, you can
change LED modes from
LINK/ACT/SPD
mode to
PoE
mode, to check the port status in each mode.
When LINK/ACT/SPD Mode LED Is Lit
When the LINK/ACT/SPD Mode LED is lit, the link/act/spd status is indicated by the LED behavior.

RJ-45 Ports
On
The port is enabled and established a link to connected device, and the connection speed is 1000 Mbps.
Flashing
The port is transmitting/receiving packets, and the connection speed is 1000 Mbps.
On
The port is enabled and established a link to connected device, and the connection speed is 10/100 Mbps.
Flashing
The port is transmitting/receiving packets, and the connection speed is 10/100 Mbps.
Off
The port has no active network cable connected or has not established a link to connected device. Otherwise, the
port may have been disabled through the switch user interface.
SFP Ports
On
