Upgrading the Cabinet Unit Firmware

When you upgrade the cabinet unit firmware (by installing a new CompactFlash
Card with a new firmware version, for example), you may also have to upgrade the
firmware for the components in the cabinet unit.
When you implement new firmware on the CompactFlash Card, the firmware for
the CU320 is upgraded automatically when you install it and switch it on.
The cabinet unit components (power section and customer terminal block) are
supplied with the firmware by means of the procedure described below.
The firmware versions for the individual components can be read in the following
parameters:
• r0128 – Firmware version of the power section
• r0158 – Firmware version of the customer terminal block
NOTE
The power supply to the components must not be interrupted while the firmware is
being upgraded.
CAUTION
New firmware should only be installed if there is a problem with the cabinet unit.
Problems with the cabinet unit cannot be ruled out after the firmware has been
upgraded.
