PowerEdge FX2 - 2400 Watt PSUs require CMC firmware version 1.40 or later

Since early 2017, 2400 Watt Power Supply Units (PSU) are available for use on the Dell PowerEdge FX2 chassis. In order to utilize the 2400 Watt PSU's on FX2, it is a requirement to update the Chassis Management Controller (CMC) firmware to version 1.40 or greater.

Note: Update the CMC firmware before installing new 2400 Watt PSU's.

If a CMC firmware version lower than 1.40 is used along with the 2400 Watt PSU's, the communication with the chassis and blades will get lost.

If the CMC is running on firmware version 1.30, the installation of 2400 Watt PSU's may cause the blades and the chassis to power down.
