Overview

SR Information: 307083

 

Product Hardware / Software Version: Lattus C5 Controller Node (Dell PowerEdge R320) and C10 Controller Node (Dell PowerEdge R620) with any Lattus software version installed. This applies to all Dell servers.

 

Problem Description: A customer reported that one of their Lattus C10 Controller Nodes was down and showed no signs of life. This issue was escallated to Dell and they provided the procedure listed below.

 

 

 


Procedure

This procedure removes all residual power from the system including the capacitors, which is referred to as a "flea power drain." Flea power is the residual or static electricity that remains on electrical components even when you have them switched off. This process also soft resets the BIOS and forces the iDRAC to reboot. This process works on Dell and other types of hardware.

 

  1. Unplug external power from the Controller Node power supplies.
  1. Slide the power supplies partially out of the Controller Node chassis.
  1. Wait 60 seconds.
  1. Plug the external power back into the Controller Node power supplies.
  1. Verify green light showing that external power is recognized by power supplies.
  1. Insert the power supplies back into the chassis with the power connected.
Using this procedure, the Dell server was revived and returned to normal operation.
