DescriptionSummary:
This document will assist with issues that can occur when powering a system on.
Symptoms:
- System will
not power on
- No power
- Cannot get
power
- No LED's
Steps to FollowInstructions for Diagnosing Why a System Will Not Power On:
-
Check incoming power. Confirm that the power cord(s) are
securely connected at both ends and the incoming power source is
known to be operational an within the required specifications.
Reference specific system using the online Sun System Handbook. Select Hardware Specifications under Information Areas for exact power requirements.
-
For systems with a physical keyswitch, make sure the system key
in the keyswitch is set to the Normal or Diagnostics position when
pressing the On/Standby button. Turn the keyswitch to the locked
position to prevent the system from being accidentally tuned off.
Remove the system key and store it in a secure place. A limited
number of systems have an interlock switch which could prevent a
system from powering on. To see if the system in question is affected reference: <Document: 1011578.1>
Verify there have been no changes to hardware configuration such
as an additional system board or power supply taken from a spare
system. System boards with USIII or USIV are not interchangeable
and may interfere with a system powering on. Also note that
power supplies used in systems with USIII CPU's are not compatible
with USIV CPU's.
-
If the system still does not power on the issue may be with the
power supply(s) or the power distribution board. Reference: <Document: 1010045.1>
