Each SPARC T4-4 server connects to the 1 GbE host management network through the four 1 GbE host management ports at the rear of each SPARC T4-4 server (NET0 - NET3 ports). However, the way the 1 GbE host management connections are used differs from the physical connections due to logical domains. For more information, see Understanding the SPARC SuperCluster T4-4 Configurations.
See Card and Port Locations (SPARC T4-4 Servers) for more information on the location of the 1 GbE host management ports.
