Resolving The Problem

Source

RETAIN tip: H205681

Symptom

IBM System x3530 M4 (7160) with a redundant Power Supply Unit (PSU) shows incorrect values for the Average Output Power and Average Input Power in Director Active Energy Manager (AEM).

The values are correct if read using the Intelligent Platform Management Interface (IPMI) command.

Affected Configurations

The system can be any of the following IBM servers:

• System x3530 M4, type 7160, any model

This tip is not software specific.

This tip is not option specific.

The following system firmware level(s) are affected:

• Integrated Management Module II (IMM2) firmware version 1.32 and earlier versions

The system has the symptom described above.

Workaround

Use the IPMI command to check the Average Output Power and Average Input Power.

Command example:

ipmitool.exe -H 192.168.70.125 -U USERID -P PASSW0RD raw 0x06 0x52 0xf1 0x6e 0x13 5 0x20 0 1 0 0xdf

Command response:

13 20 00 15 14 00 00 3f 00 4a 03 f9 04 a1 25 80 09 60 09

In this example, '00 3f' is the average output power, which is 63 watts, and '00 4a' is the average input power, which is 74 watts.
