Hi,
do you use 2 power supplies?
Please note that the half chassis models (OS6855-14 and OS6855-U10) use different power supplies than the 24 port models.
The power supplies for OS6855-U10 and OS6855-14 models come in the form of a power brick in either AC or DC variant.
OS6855-PSS : AC power supply provide only system power (PS-I40AC, DC Output 12V 40W)
OS6855-PSS-P : AC power supply provide PoE only power (PS-I66AC-P, DC Output 54V
66W)
On OS6855 you have PS1 and POE1.
OS6855-14 switches using PoE also require a second power supply.
For this configuration, plug the longer connector cable from the PoE power supply (OS6855-PSS-P) into the PoE1 port on the rear panel of the chassis.
Connect the shorter PoE connector cable to the female AC connector on the system power supply (OS6855-PSS).
Connect OS6855-PSS-P longer connector to PS1 port on the rear panel.
If all OK then you will be able to see:
