  "whatItIs": "Dell OpenManage Server Administrator (OMSA) runs an embedded web server on TCP 1311 and serves its console over HTTPS at https://host:1311. Through it an authenticated operator reads hardware health, RAID and firmware state, and performs management actions on a PowerEdge server. The IANA registration for 1311 is the unrelated \"RxMon\", so on a scan of Dell hardware treat 1311 as OMSA. Its presence marks the host as a physical Dell server with the management agent installed.",
