Power supply

The server is equipped with one or two power supplies, labeled PS1 and PS2. Each power supply
has an AC power input receptacle and an LED that indicates the power state of the server.
The server has the following power states: standby power, full power, and off. To achieve the
standby power state, plug the power cord into the appropriate receptacle at the rear of the server.
To achieve full power, plug the power cord into the appropriate receptacle, and either push the
power button or enter the iLO 3 MP PC command. In the off state, the power cords are not connected
to a power source.

Diagnostics

A suite of offline and online support tools are available to enable manufacturing, field support
personnel, and the customer to troubleshoot system issues. In general, if the operating system is
already running, then HP recommends that you do not shut it down and instead, use the online
support tools.
If the operating system cannot be booted, then use the offline support tools to help resolve the
issue. The offline support tools are available either from the UEFI partition, or from the IPF Offline
Diagnostics and Utilities CD (IPF systems only). After the issue preventing booting has been resolved,
boot the operating system, and then use the online support tools for any further testing.
If you cannot reach UEFI from either the main disk or from a CD, you must troubleshoot, using the
visual fault indicators, console messages, and system error logs that are available.

Online diagnostics and exercisers

Online support tools are available which permit centralized error archiving, and which provide
hardware inventory tools, as long as the agents/providers that support them are installed on the
managed server.
On HP-UX systems, the legacy tools within OnlineDiag are supported. The online support tools, on
the HP-UX 1 1.23 and greater operating systems, include the WBEM features added by
SysFaultMgmt.

is released. The iLO 3 Physical Presence button enables you to reset iLO, enter TPM physical
presence mode, and enter security override mode.
A momentary press of the button resets iLO, clears any security override or TPM physical
presence mode that were initiated by this button, and returns the serial port to iLO mode.
A greater than 4-second and less than 8-second press of the button places the system in
physical presence mode for up to 15 minutes.
A greater than 8-second and less than 12-second press of this button places iLO into
security override mode for up to 15 minutes. Security override mode enables you to enter
iLO without being challenged for a password enabling you to set up users.
The UID LED blinks once after holding the button for 4 seconds and once after holding
the button for 8 seconds to help you gauge how long the button press has been held.
NOTE: The iLO 3 physical presence pinhole button is located behind the sheet metal grill
and the circular punch-out in the rear panel.
