These settings will allow the Juice Box to power any IEEE 802.3af compatible device
up to the full rated specification power limit. You can modify the port settings to detect
legacy devices or limit the individual port power. To change the port settings please go
the Port Settings section in this manual.
6.
Connect devices to be powered.
•
First determine if the device is designed to meet 802.3af or is a compatible legacy
device. If you are unsure please see the section on Compatible Devices.
•
Select an unused port and configure the port according to the device to be
connected.
•
Connect a patch cord from the Ethernet switch to the Juice Box DATA input
connector. (The DATA input connector is the lower one of the port pair).
•
Connect the Ethernet line that goes to the device to be powered to the DATA +
POWER output connector. (The DATA + POWER output connector is the upper
one of the port pair).
•
When you connect a device, the Port LED indicator should change color to green to
indicate the Juice Box is providing power to the device. Please see the LED
Indicator section for a full description of the different Port LED Indicator colors.
5. LED Indicators
There are three different types of LED indicators in the Juice Box:
•
Power over Ethernet Port Indicator
•
System Power Indicator
•
Ethernet Link Indicator (Units with WEB/SNMP Interface)
The
PoE Port
indicator gives the following information:
•
Green – The Juice Box is providing power to the attached device.
•
Flashing Green – The Juice Box has detected a valid signature from the device but
the current drawn by the device is below the minimum of 10mA. This would
happen only if it were a defective 802.3af device or an unusual legacy device.
•
Yellow – The Juice Box has detected a fault condition. The Juice Box will indicate
a fault condition if any of the following occur:
o
The power drawn by the device exceeds the amount in the Port Power
Setting.
o
The power drawn by the device exceeds the Device Classification.
