How to limit management traffic (ssh and https) toward switches PC8164

Hi there!
i want to limit traffic to manage the PowerConnect devices PC8164 for ssh and https.
let say, that only this subnet: 192.168.7.0/24 and host 192.168.8.8 to have access for ssh and https for managing the devices.
How is this done on dell PC 8164?
Regards!
