NonStop NS2400 Series Planning Guide

Maintenance Switch
The HP ProCurve maintenance switch provides the communication between the NonStop NS2400
system through the VIO enclosures, CLIMs, the optional UPS, and the system console running or
accessing OSM software.
The NonStop NS2400 system requires multiple connections to the maintenance switch:
• One connection from the ME ENET port on each of the two VIO enclosures for OSM Low-Level
Link connectivity
• One connection from slot 6B, port A on each of the two VIO enclosures for the OSM Service
Connection and other up-system connectivity (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 HP that runs maintenance and diagnostic
software for NonStop NS2400 series systems. When supplied with a new NonStop NS2400
series system, system consoles have factory-installed HP and third-party software for managing the
system. You can install software upgrades from the HP NonStop System Console Installer DVD.
Some system console hardware, including the Windows Server system unit, monitor, and keyboard,
can be mounted in the NonStop NS2400 system 19-inch rack. Other Windows Servers are installed
outside the rack and require separate provisions or furniture to hold the server hardware.
NOTE: System consoles cannot be installed in the rack for DC-powered NonStop NS2400T and
NS2400ST systems. Instead, these systems use the desktop system console model.
For more information on the system console, see “System Consoles for NonStop NS2400 Series
Systems” (page 160).
UPS (Optional)
IMPORTANT: You must change the ride-through time for an HP-supported UPS from the
manufacturing default setting to an appropriate value for your system. During installation of a
NonStop NS2400 system or HP UPS, your service provider can refer to the "Setting the Ride-Through
Time and Configuring for Maximized Runtime" procedure in the NonStop NS2200 Series and
NS2400 Series Hardware Installation Manual for these instructions.
An uninterruptible power supply (UPS) is optional but recommended where a site UPS is not
available.
A UPS can be combined with an extended runtime module (ERM) to extend battery run time. For
more information, see “ERM (Optional with UPS)” (page 33).
Depending on your power configuration, HP supports these options:
• “UPS for a Single-Phase Power Configuration (Optional)” (page 33)
• “UPS for a Three-Phase Power Configuration (Optional)” (page 33)
WARNING! To avoid tipping and stability issues, you must install UPSs and ERMs in the lowest
portion of the system. For details, see the UPS user guide.
