B.4 

Power Status and overload (IEEE 802.3af) 

RT-PoE commands: 

PSE action 

reset 
connect on 
detect ok 
class 3 
set 20 

 

 

Enable power to port 

Verify that PSE sees that device taking power. 

status 

(verify that power is 

on)

 

 

meas2 

(verify that voltages 

are as expected )

 

 

set 350 

(Verify that PSE is providing full power) 

set 390 

(Verify that PSE sees overload and shuts off 
power) 

status 

(verify that power is 

off)

 

 

B.5 

Power Status and overload (IEEE 802.3at) 

 

Same as above, but use “class 4”, and “set 600” for full power and “set 660” for overload  

B.6 

Power Status and overload (UPoE) 

 

Same as above, but use “set 1200” for full power and “set 1320” for overload  

B.7 

Data transmission under power (IEEE 802.3af) 

RT-PoE commands: 

Check after commands issued 

(as above for 
specific test 
required) 

 

 

Enable power to port 

Verify that PSE sees that device powers up. 

status 

(verify that power is 

on)

 

 

ext on 

Run traffic test between port pairs 1 and 2, 3 and 
4,…23 and 24. Verify no errors.
