The NonStop BladeSystem requires multiple connections to the maintenance switch. The following
describes the required connections for each hardware component.
BladeSystem Connections to Maintenance Switch
• One connection per Onboard Administrator on the NonStop BladeSystem
• One connection per Interconnect Ethernet switch on the NonStop BladeSystem
• One connection to the optional UPS module
• One connection for the system console running OSM
CLIM Connections to Maintenance Switch
• One connection to the iLO port on a CLIM
• One connection to an eth0 port on a CLIM
IOAM Enclosure Connections to Maintenance Switch
• One connection to each of the two ServerNet switch boards in one I/O adapter module
(IOAM) enclosure.
• At least two connections to any two Gigabit Ethernet 4-port ServerNet adapters (G4SAs), if
the NonStop BladeSystem maintenance LAN is implemented through G4SAs.
System Console
A system console is a personal computer (PC) purchased from HP that runs maintenance and
diagnostic software for NonStop BladeSystems. When supplied with a new NonStop BladeSystem,
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 image.
Some system console hardware, including the PC system unit, monitor, and keyboard, can be
mounted in the NonStop BladeSystem's 19-inch rack. Other PCs are installed outside the rack
and require separate provisions or furniture to hold the PC hardware.
For more information on the system console, refer to “System Consoles” (page 89).
UPS and ERM (Optional)
An uninterruptible power supply (UPS) is optional but recommended where a site UPS is not
available. HP supports the HP model R12000/3 UPS because it utilizes the power fail support
provided by the OSM. For information about the requirements for installing a UPS, see
“Uninterruptible Power Supply (UPS)” (page 32).
There are two different versions of the R12000/3 UPS:
• For North America and Japan, the HP AF429A is utilized and uses an IEC309 560P9 (60A)
input connector with 208V three phase (120V phase-to-neutral)
• For International, the HP AF430A is utilized and uses an IEC309 532P6 (32A) input connector
with 400V three phase (230V phase-to-neutral).
Cabinet configurations that include the HP UPS can also include extended runtime modules
(ERMs). An ERM is a battery module that extends the overall battery-supported system run time.
