Managing Superdome Complexes: A Guide for HP-UX System Administrators

Overview of the Superdome System Environment

HP Superdome System Hardware Components

Chapter 120

Figure 1-3 HP Superdome Cell and I/O Connection

The backplane-connection cables (Flex cables) establish how

backplane crossbar components communicate within a Superdome

server complex.

• Power and Service (“Attention”) Lights

Each cell and each I/O chassis has two sets of lights (LEDs):

power/status LEDs (green) and service LEDs (amber/yellow).

Each cabinet has a red service (“Attention”) LED.

Chapter 4 includes details on using the fruled command or Partition

Manager to manipulate (turn on or off) the cell, I/O chassis, and

cabinet LEDs.

See the fruled(1) and parmgr(1M) manpages for details.

• Power and Cooling (Fans)

Both power and cooling can be redundant.

You can check the status of fans and power supplies using various

methods described in this chapter and in Chapter 3. For example, the

parstatus -V -b0 HP-UX command displays detailed information

about cabinet 0’s power and cooling conﬁguration.

Consult with your HP service orsales representative to determine the

amount and placement of power and cooling components.

The following power components can be installed in each Superdome

cabinet: one or two main power sources (PDCA 0 and PDCA 1), three

backplane power components (HBPB 0–2), and up to six bulk power

CellI/O Chassis
