Purpose

• If your system is powered on and you are seeing errors or warnings associated to a Power Supply Unit, see Document: 1007049.1  Troubleshooting Power Supply Warnings or Failures on Sun Fire [TM] Serengeti or LightWeight8 systems.
  
• If you have a component that will not power on, see Document: 1013120.1  Troubleshooting "can't power on" component errors on Sun Fire [TM] Serengeti or LightWeight8 systems.

Symptoms:

• The system may be described as completely down, dead, or unresponsive to ping, telnet, or similar.
• There may be no lights or LEDs lit on the system.
• The fans may not be spinning on the platform.
• The System Controller may or may not be reachable.  Domains are likely to be down, unreachable, unable to ping, logged into, etc.
• Multiple systems in the same rack or environment could be effected or this could be a single system event.

Assumption:

This document assumes that AC power source (for Sun Fire[TM] systems) is 200-240 VAC, 47-63 Hz, 32 A(per power cord) and DC power source (for Netra systems) is -48VDC / -60VDC.  See the Sun System Handbook (SSH) for each system's specific environmental requirements.

Troubleshooting Details

The steps will provide instructions or a link to a document, for validating the step and taking corrective action  as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

1.  Verify the system in question is completely powered down.

• The domains will be completely unaccessible and the System Controller should also be unaccessible to pings, telnet, serial connection, or SSH connections.
• There should be no lights on the system or fans spinning.

2.  Verify this is the only system suffering a power outage.

• If other systems are suffering power outages, the issue is external to this system and needs to be troubleshot by the site electrician or data center management team.
• If the issue affects only a single rack within the entire data center configuration troubleshoot the rack's power distribution components and the power being provided to this rack configuration.

3.  Verify the RTS, RTU, and AC Input Modules have their power cables securely attached.

• Reference the appropriate System Service Manual (Power section) for pictures of each of these devices:
• Sun Fire 6800/4810/4800/3800 Systems Service Manual (pdf)
• Sun Fire[TM] V1280/Netra[TM] 1280 Systems Service Manual (pdf)
• Sun Fire[TM] E2900 System Service Manual (pdf)
• Sun Fire[TM] E4900/E6900 Systems Service Manual (pdf)
• Netra[TM] 1290 System Service Manual (pdf)

• Reference Document: 1011893.1 Sun Fire [TM] 3800-6800 AC/DC Power Distribution for a diagram of how the parts connect to each other.
• See the Assumption listed in the beginning of this document for power source requirements.

• Same references should be used from Step 3 to verify the breaker status with the addition of confirming that the site's electrician or data center manager has confirmed this system's power source is in working order.
• Future steps may require hardware replacement - If so, Oracle Support Services may need to be engaged to proceed.  Try to validate what checks you can on your own and engage support if/when it is determined that hardware must be replaced.
  

• If the lights on the RTS/RTU are not lit or the fault light is lit, and external power is confirmed fine (previous steps), the RTS/RTU is suspect.

• If the lights on the AC Input Module are not lit or the fault light is lit, the AC Input Module is suspect.

• If the lights on a PSU is not lit or a fault light is lit on one unit, the PSU is suspect.
  
• If the lights on multiple PSUs are not lit or a fault light is lit on multiple units the Power Centerplane is suspect.

• Discuss the next steps with Oracle Support Services, who should already be engaged to replace components in the system (if they are suspect). 
  
• They may need to collaborate with the next level of technical support to coordinate the next steps involved in resolving this issue.
