Although the upgrade does not impact rPDU operation, the front panel buttons are disabled and you cannot use the
LCD menus to manage the rPDU during the upgrade.
During an MCU upgrade, the LCD displays a Flash Update in Process message and provides a progress bar as the
upgrade progresses (see Figure 2). If the upgrade is interrupted, recovery processes allow the upgrade to restart. If the
MCU upgrade fails, the LCD displays a Flash Error message and the backlight changes to amber text with a dark red
background.
