Does the Sun Fire X2200 M2 Sever have a dedicated management network port?
No, similar to the Sun Fire X2100, network management traffic shares access via the 2nd 10/100/1000 NIC port. The Sun Fire X2100 M2 and Sun Fire X2200 M2 servers provide four Gigabit Ethernet interfaces. The port labeled NET MGT provides shared access to the physical NET 1 interface for the service processor. This feature is provided by use of the Broadcom Universal Management Port (UMP) specially designed for this purpose. The UMP port allows an internal device such as the service processor to share a host Ethernet interface without significantly affecting traffic flows to either unit.
