Can you post a diagram of your environment
are the two connections on different vlans?
if this is a L2 switch , you will need a L3 device to pass traffic between two differant vlans
log into a device that is on VLAN A, can it ping a device on VLAN B
try the same from VLAN b to VLAN A
can you ping the SW server from both vlans
if not, you may have a routing issue , f/w block or access lists that are affecting you
