Powering on the server
Before the introduction of the HP ProLiant Gen8 servers, some HP ProLiant servers (particularly ML
and DL) could be powered on through the power button within a few seconds after AC power was
connected. If an AC power loss occurs on HP ProLiant Gen8 servers with iLO 4, approximately
30 seconds must elapse before the servers can power on again. The power button will blink,
indicating a pending request, if it is pressed during that time.
This delay is a result of the iLO firmware loading, authenticating, and booting. iLO processes
pending power-button requests when initialization is complete. If the server does not lose power,
there is no delay. A 30-second delay occurs only during an iLO reset. The power button is disabled
until iLO is ready to manage power.
A power-button watchdog allows the user to power on the system using the power button when
iLO does not boot successfully.
