UPS firmware update for IBM LCD 11KV UPS Update v01.10.0002 - IBM System x

Version 01.04.0002
Severity: Initial release.

Version 01.08.0003
09/08/2011

IBMP/N 53959KX, 11K Online UPS firmware change notes for production firmware version 1.08.0003.

  1. Added the additional capability to select a 200 Volt AC UPS output voltage selection, per IBM request.
  2. Repaired a bug in the timer portion of the Automatic Battery Management (ABM) section of the UPS firmware. This bug caused the Automatic Battery test to re occur again and the charging cycle to re start over, 48 hours after performing the first 3 month Automatic Battery test. Normal operation is that the Automatic Battery test is only performed once every 3 months, after a full battery charge cycle.

Version 01.10.0002
08/05/2013

IBM P/N 53959KX, 11K Online UPS firmware change notes for production firmware version 1.10.0002.

  1. Changed the detection method algorithm for determining the “Battery Disconnected” alarm. A small percentage (approx. 5 %), of units would not always detect this alarm correctly when the battery was actually disconnected.
  2. Changed the detection time required to report a “Battery Needs Service” alarm from 1 minute to 10 minutes, to help filter the detection data and avoid reporting a false alarm.
  3. Changed the firmware to save the auto restart flag to the EEPROM, when the DBStartUp time counts down to 0 with Utility Loss. This solved an IBM reported issue where the UPS would not always automatically restart after a power failure shutdown and recovery.
  4. Changed the production version firmware number reported from the code to 1.10.0002 (previously was 1.08.0003).
