My D555 camera is working
I have bought 2 cameras of D555 and both of them are not working when connected in PoE. The LED lights of the ethernet port of the camera are not being turned on when the PoE is connected. Also i have tried to connect the camera using USB but it says the camera is not being detected by the laptop

Hi Sh Sh Some D555 users have reported that the LEDs do not light even when the camera is operating normally, so this is not necessarily an indication of a problem.
Please ensure that the USB cable is not connected to the camera when using PoE as having USB plugged in will prevent the camera from working on PoE.
In regard to testing the camera with USB, it should be detectable if you do not have the PoE ethernet cable plugged into the camera. Are you using Windows or Linux, please?

I tried the camera only + usb with windows and i have tried to use linux windows and try to type ros2 topic list but the camera was not showing. Also I have tried to connect the camera through ethernet switch but it did not work when i tried to do ros2 topic list on Linux system in windows.

Please use the instructions at the link below to confirm that the Windows camera privacy settings are set to On to allow access to the camera on a USB connection.

The link below has an illustrated guide for configuring the D555's PoE ethernet settings in Windows.

Which version of the RealSense SDK / RealSense Viewer are you using, please? The oldest version that supports D555 is 2.56.4
If your version is 2.56.4 or newer (the current latest is 2.57.4), the SDK needs to have been built from source code with CMake with the flag -DBUILD_WITH_DDS=ON included in order for the SDK to be installed with PoE support enabled. The link below provides instructions about building the SDK on Windows from source.

You can also build the SDK on Linux with CMake with the -DBUILD_WITH_DDS=ON flag included in the CMake build command.
The USB cable chosen for use with the camera should be a high quality one suited for data transfer and not one that is only intended for charging up devices.
