hikvision camera connection, poe injector, switch, router

[Rafal9184]

Hello,
I've recently purchased 5x Hikvision IPCAM-B4 cameras.
My network equipment:

• router: TP-Link Archer C6
• switch: HP 1820-48g switch j9981a
• poe injector

Everything works fine when I'm connecting the camera through the poe injector to the rear port of the router, but when I tried to connect the camera through the poe injector and the switch, I lost the connectivity.
Any ideas what could be wrong here? Any specific configuration needed on the switch side?
I would like to achieve below schema:
ipcam <-> poe injector <-> switch <-> router

Thank you in advance for any advices

Ok, I've already solved the problem.
I had to manually set the link speed on the switch side, even though the negotiating process was successful.
It's a little weird, but it works.
Maybe someone else will have similar problem, so this thread can be useful.
