NonStop NS14000 Planning Guide (H06.10+)

As this illustration shows, the OSM console connects to a closed and private service LAN,
connecting the VIO enclosures via a maintenance switch (a ProCurve 2524).
Other hardware modules contain at least one microprocessor and firmware that performs
maintenance functions for their local logic:
• NonStop Blade Element
• Fibre Channel disk module (FCDM)
The ServerNet fabrics, rather than the dedicated service LAN, provide maintenance
interconnection to the OSM console for these modules.
Dedicated Service LAN
A dedicated service LAN provides connectivity between the OSM console running in a PC and
the maintenance firmware in the system hardware. This dedicated service LAN uses a ProCurve
2524 Ethernet switch for connectivity between the VIO enclosures and the system console.
This subsection includes:
• “Basic Configuration” (page 115)
• “Fault-Tolerant Configuration” (page 115)
• “IP Addresses” (page 116)
• “Ethernet Cables” (page 118)
• “SWAN Concentrator Restrictions” (page 118)
• “System-Up Dedicated Service LAN” (page 118)
• “Dedicated Service LAN Links With Two VIO Enclosures” (page 119)
• “Initial Configuration for a Dedicated Service LAN” (page 120)
• “Operating Configurations for Dedicated Service LANs” (page 120)
An Integrity NonStop NS14000 system requires a dedicated LAN for system maintenance through
OSM. Only components specified by HP can be connected to a dedicated LAN. No other access
to the LAN is permitted. The dedicated service LAN provides connectivity between the OSM
console running on a PC and the maintenance firmware in the system hardware.
