We can upgrade the BME XBP ••00 rack firmware by downloading a new firmware version with Unity Loader through the CPU or a BME CRA 312 •0 module.

The firmware download can be performed by connecting to either of the following:

• The CPU mini-B USB connector
• The CPU Service port
• The Ethernet network

Refer to the CPU firmware upgrade procedure for a description of the download procedure. Also make sure the necessary security permission should be enabled.
