SFP Link FortiSwitch HP

Hello world,

we are currently replacing our hp / hpe / aruba switches with fortiswitches. We create a new star and replaced our coreswitch hp 8212 with a fs1048d and every client switch with fs448d/fs424d.

Now I need to connect one old aruba HP 2530-48G-PoE+-2SFP+ Switch (J9853A) to the new coreswitch (fs1048d). The 2530 had a redundant link on the hp 8212, but I cant get a link on my fs1048d. All the cables and transcievers are fine, I checked everything. The fs1048d shows me a link, the hp does not. The 2530 gets an uplink on the hp switch, it does not matter which port I use. But it also doesn't get an uplink to the fortiswitch.

Old:

HP 8212 link --> 2x SFP --> 2530 link

Current:

HP 8212 link --> 1x SFP --> 2530 link

FS1048 link --> 1x SFP --> 2350 no link

Anyone any idea?

No LACP or spanning tree is configured.

Yes, I have the lights on both ends.
