Opened: Sep 11, 2014

Severity: 2-Critical


When powering up a DC chassis, if one DC PSU is plugged in before the other DC PSU, the system may report the second PSU to be plugged in as an AC PSU.


TMOS reports the wrong PSU type to the user.


The following platforms with 2 DC PSUs installed: 10000, 10050, 10055, 10200, 10350, 12050


Removing the DC PSU which is being reported incorrectly and reinstalling will work around this problem: - Remove PSU for > 30 seconds or until TMOS reports PSU is not present. - Insert PSU

Fix Information

On BIG-IP 10000/12000 Series platforms, the system no longer reports a secondary DC power supply that is installed, but not powered on, as an AC power supply, when power is applied to the secondary DC power supply.
