System-Up Dedicated Service LAN

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

NS-series 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 G4SA can reside in modules 2

and 3 of the same IOAM enclosure or in module 2 of one IOAM enclosure and module

3 of a second 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.

If NonStop S-series I/O enclosures are connected to the system, one G4SA can reside

in either module 2 or 3 of an IOAM enclosure and in a NonStop S-series Ethernet

adapter (such as an E4SA, FESA, or GESA) in either slot 53 or 54 of the NonStop

S-series I/O enclosure. When installing Ethernet adapters for the dedicated service

LAN in an IOAM enclosure for an Integrity NonStop NS-series system and in a

NonStop S-series I/O enclosure, it is important that each Ethernet adapter connect to

the X and Y fabric. For information about the NonStop S-series I/O enclosure and the

Ethernet adapters that can be installed in it, see the NonStop S-Series Planning and

Configuration Guide.
