No connectivity between HP switch and firewall

[eXPlosion_]

Hi,
we have CR50iNG Cyberoam which is upgraded to Sophos XG Firewall. We just wanted to connect additional HP procurve 5120 switch to network.
Sophos have allready connected two HP switches 2510 on port C and port D.

Working HP 2510 configuration:

ip default-gateway 10.10.19.254
vlan 1
   name "DEFAULT_VLAN"
   no ip address
   no untagged 1-24
exit
vlan 17
   name "VLAN17"
   tagged 23-24
   exit
vlan 18
name "VLAN18"
   untagged 19
   tagged 23-24
exit
vlan 19
   name "VLAN19"
   untagged 21-22
   ip address 10.10.19.253 255.255.255.0
tagged 23-24
exit

5120 is connected on port 1/0/46 to firewall. There is no connectivity when pinging 5120 from firewall or from management pc to HP switch.
I also tried this configuration, but still no response:
