NonStop NS1200 Planning Guide

Dedicated Service LAN
An Integrity NonStop NS1200 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.
This subsection includes:
• “Basic Configuration” (page 68)
• “Fault-Tolerant Configuration” (page 69)
• “IP Addresses” (page 69)
• “Ethernet Cables” (page 71)
• “SWAN Concentrator Restrictions” (page 71)
• “System-Up Dedicated Service LAN” (page 71)
• “Dedicated Service LAN Links With Two VIO Enclosures” (page 72)
• “Initial Configuration for a Dedicated Service LAN” (page 73)
• “Operating Configurations for Dedicated Service LANs” (page 73)
Basic Configuration
A basic dedicated service LAN that does not provide a fault-tolerant configuration requires
connection of these components to the ProCurve maintenance switch installed in the modular
cabinet:
• One connection for each system console running OSM.
• One connection for each VIO enclosure.
• At least one connection to an Ethernet port in each VIO enclosure. You must have these
connections to use the OSM Service Connection and OSM Notification Director.
• (Optional) one connection to one or more uninterruptible power sources (UPSs).
