Assign static IP address to MAC address in N3024 DHCP server

Hi,

I've created a few DHCP scope in N3024.

All these DHCP scope are working, devices able to get IP addresses.

I wish some devices (e.g. printer, AppleTV, etc.) can get a static IP address from this scope.

For example, the DHCP scope in 172.24.23.0 /24. And I wish printer (configured as DHCP) can get IP address 172.24.23.11.

So I want to bind IP address to the specific MAC address.

How I can achieve this goal in PowerConnect N3024? 

Thanks!
