Purpose

Description
This document addresses power outages affecting Sun Fire [TM] 3800, 4800, 4810, E4900, 6800, E6900 (Serengeti) and Sun Fire [TM] v1280, E2900, and Netra [TM] 1280, 1290 (LightWeight8) systems.
This document covers situations where the system is unable to be powered on, believed to be down (dead), or is simply unreachable and the suspect cause is related to power problems either within the system, rack, or environment.

• 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.
