Step 2. Issue the HP-UX commands to check the power status for the
Superdome complex components of interest to you.
You can check power status details by using the HP-UX commands
shown in the following list.
For more details on these HP-UX commands, see the manpage for
parstatus (1), frupower (1M), and rad (1M).
This list covers cabinet, cell, I/O chassis, and PCI card slot power.
• Cabinet Power—Use the parstatus command for Superdome
cabinet power information.
Specify both the verbose (-V) and cabinet number (-b#) options.
For example, parstatus -V -b0 prints a detailed status for cabinet
number 0.
The parstatus command can give details about each cabinet’s bulk
power supplies (BPS 0–5, if installed) and backplane power boards, in
addition to other details about cabinet fans and blowers.
