The nx360 M4 provides a dedicated Ethernet port that allows connection to the
IMM2. It is a port to access the IMM2 separately from the onboard two-port 1 Gb
Ethernet controller. Alternatively, the first 1 Gb Ethernet port from the onboard
controller can be configured in Shared mode to allow access to the IMM2. With
Shared mode enabled, the dedicated IMM port is disabled.

The nx360 M4 supports attachments to the external SAS storage expansion
enclosures using the ServeRAID M5120 SAS/SATA Controller. Table 4-31
