Maintenance Switch
The HPE ProCurve maintenance switch provides the communication between the NS2100 system
through the VIO enclosures, CLIMs, the optional UPS, and the system console running HPE
NonStop Open System Management (OSM).
The NS2100 system requires multiple connections to the maintenance switch:
•
One connection from the ME ENET port on each of the two VIO enclosures
•
One connection from slot 6B, port A on each of the two VIO enclosures for the OSM Service
Connection and OSM Notification Director (optional if a dedicated service LAN is implemented
using CLIMs)
•
One connection to the iLO port on a CLIM
•
One connection to the iLO port on a blade element
•
One connection to an eth0 port on a CLIM
•
One connection to the optional UPS module
•
One connection to the system console running OSM
System Console
A system console is a Windows Server purchased from Hewlett Packard Enterprise that runs
maintenance and diagnostic software for NS2100 systems. When supplied with a new NS2100
system, system consoles have factory-installed Hewlett Packard Enterprise and third-party
software for managing the system. You can install software upgrades from the HPE NonStop
System Console Installer DVD.
Some system console hardware, including the Windows Server system unit, monitor, and
keyboard, can be mounted in the NS2100 system 19-inch rack. Other Windows Servers are
installed outside the rack and require separate provisions or furniture to hold the server hardware.
