Step Condition
1 Chassis appears "dead" -- no
front panel LEDs are on, and
no fans are running.
2a Server does not power on
after front panel Power
button is momentarily
depressed; for example, is
depressed for less than four
seconds.
NOTE: This step assumes
BMC is running.

Action
Nothing is logged for this condition.
1. For new server installations, review the install procedures.
2. Verify that the power cords are connected to both the power supplies and
to the AC receptacles.
3. Verify that AC power, at the proper AC voltage levels, is available to the
receptacles.
4. Check the front panel connector and the cable to the rest of the system.
5. If the Power button integrated LED on the front panel remains off, reseat
the power supplies, replace the power cords, and replace the bulk power
supplies, in that order (see
The preceding problem is fixed when the front panel LED states are as follows:
System Health is Off; Internal Health is Off; External Health is Off; and Power
is Steady Amber.
A fatal fault has been detected and logged, attempting to power on the server
(System Health is Off, Internal Health is Off, External Health is Off, and Power
is Steady Amber).
1. Examine each power supply's LEDs -- if not Steady Green, replace power
supply (see "Power Subsystem Behavior" (page
2. Examine the iLO 2 MP logs for events related to bulk power supplies (see
"Power Subsystem Behavior" (page
Preceding problem is fixed when BMC's heartbeat LED is Flashing Green,
and the front panel LEDs are as follows: System Health is Off, Internal Health
is Off, External Health is Off, and Power is Steady Green.
A warning or critical failure has been detected and logged after server powers
on (System Health is Flashing Amber, Internal Health is Off /Steady Green,
External Health is Flashing Amber, and Power is Steady Green)
1. Examine each power supply's LEDs. If not Steady Green, replace power
supply (see "Power Subsystem Behavior" (page 161)
2. Examine each external fan's LED. If not Steady Green, replace fan(s) (see
"Cooling Subsystem" (page 163)
