NonStop NS14000 Series Planning Guide (H06.13+)

NOTE: Because the system console and maintenance switch are single points of failure that could
disrupt access to OSM, this configuration is not recommended for operations that require high
availability or fault tolerance.
One System Console Managing Multiple Systems
The one system console on the LAN must be configured as the primary system console.
Because all servers are shipped with the same preconfigured IP addresses, you must change the
IP addresses for the second and subsequent servers before you can add them to the LAN. To add
a system to the LAN, see the NonStop Dedicated Service LAN Installation and Configuration Guide.
Primary and Backup System Consoles Managing One System
Two maintenance switches provide fault tolerance and extra ports for adding system consoles. You
must change the preconfigured IP addresses of the second and subsequent system consoles before
you can add them to the LAN.
See “Fault-Tolerant LAN Configuration” (page 87) for an illustration of this configuration.
Primary and Backup System Consoles Managing Multiple Systems
If you want to manage more than one node from a fault-tolerant pair of consoles, you can daisy
chain the maintenance switches together. This configuration requires an IP address scheme to
support it. Contact your HP service provider to design this configuration.
