I need to eliminate the current physical server and promote the existing switch, SG300-52, as a DHCP server and DNS server. Can the SG300-52 be promoted to DHCP server and DNS server without any physical server?

Thank you so much. The DHCP configuring as the DHCP server (no need any DHCP server else referred ) or DHCP relay (and need another DHCP server to referred)

you need to configure dhcp in L3 mode. change switch mode to L3 and configure DHCP server. not relay.

Thank you so much.

You mean to the DHCP configuring as the DHCP server (no need any DHCP server else to referred ) or DHCP relay configuring (and need another DHCP server to referred).
