Dell switch S3124 vlans not working

Hi,

I have a cisco 3560 in my organization, but that's out of support and EOL so i want to replace this switch with a Dell S3124 switch. 

In the current situation i have the following VLANS.

VLAN data (192.168.0.50 ip - management)
VLAN test (192.168.100.1 ip)
VLAN backup (192.168.200.1 ip)

I configured the Dell S3124 and made the following VLANs

VLAN data (192.168.0.254 ip - management)
VLAN test (192.168.100.254 ip)
VLAN backup (192.168.200.254 ip)

I have a POe+ overall switch, that's giving the uplink to both switches, both on port 1.  I can ping the devices on the Dell S3124 switch that are in VLAN data ( default vlan). but i'm not able to ping the other devices in other VLANs on the new switch.
