Hello,
IS5022 is an unmanaged switch so if you are referring to management interfaces configuration - it has none. it is simply a plug and play switch where a subnet manager has to be configured on a different entity in the network (Managed switch, Host).
Here's a link to the User Manual :

With regards to the host, you can check basic connectivity if you'll start the subnet manager service :"/etc/init.d/opensmd start" and run "ibstat" to check the ports are active and up.
Cheers,
