15.0 Cable and Power over Ethernet (PoE) Test
PoE technology is used to provide both data and power over the same Ethernet cable. It is widely used in WiFi networks as WiFi
Access Points or repeaters.
For PoE test, a CAT5, 5E, or 6 cable should be connected to the RJ45 connector on the Air Expert’s connector panel (refer to
). The Air Expert Module emulates a PD (Powered Device) in order to provide PoE measurements.
Cable Diagnostics
Cable Diagnostics
The following measurements are reported when the Ethernet cable is connected to a switch or router port.
Ethernet Link Status
The Ethernet Link is UP and the connection is in Full Duplex Mode
The Ethernet Link is UP but the connection is in Half Duplex Mode
The Ethernet Link is DOWN
Pair Termination
Indicates properly terminated pair
Indicates an open pair
Indicates improper pair termination: short, high crosstalk or anomalous coupling
Cable Length estimation of properly terminated pair
: An estimation of cable length is provided for properly terminated
pair in meters/feet. The cable range support is from 7 to 120 meters, with an accuracy of 5 meters. CAT 5 or better
cabling is required for valid results
Blink Port:
Use the Blink Port function key to blink the LED on an Ethernet router or switch port, where the Air Expert is
connected. Blinking is triggered by bringing the link up and down. .
POE Measurements
PSE Type
: Determine the PSE (Power Source Equipment) Type. The type detected are PoE (802.3af standard) or
PoE+ (802.3at standard). Display N/A is not PoE detected.
Loaded Voltage
: Measure the Voltage provided in Volts.
Pairs Used
: Displays the wire Pairs used for PoE.
