I could not find ansible module specific to dell switches yet. Existing modules mostly refer to dell emc products.
Short version: the Ansible connection type you want is
The N1548P's operating system, OS6, doesn't have a RESTAPI like OS10/SONiC. Subsequently, Ansible is effectively just acting as a passthrough to the CLI over SSH. The documentation for it is here. To quote the docs, the setup looks like this:
ansible_connection: ansible.netcommon.network_cli ansible_network_os: dellemc.os6.os6 ansible_user: myuser ansible_password: !vault... ansible_become: yes ansible_become_method: enable ansible_become_password: !vault... ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q bastion01"'
Obligatory legal note: I work for Dell.
