System-Up Dedicated Service LAN

When the system is up and the OS running, the ME connects to the NonStop NS1000

system’s dedicated service LAN using one of the PIFs on each of two G4SAs. This

connection enables OSM Service Connection and OSM Notification Director

communication for maintenance in a running system.

For a fault-tolerant dedicated service LAN, two G4SAs are required, with one

connected to each ServerNet fabric, X and Y. These G4SAs can reside in modules 2

and 3 of the same IOAM enclosure. When the G4SA provides connection to the

dedicated service LAN, use the slower 10/100 Mbps PIF A rather than one of the high-

speed 1000 Mbps Ethernet ports of PIF C or D.
