Model 4200-SCS User’s Manual Section 1: Getting Started
Firmware upgrade
When the system software is updated, you should upgrade firmware for each 4200-SCS
instrument. Before starting the firmware upgrade, make sure the 4200-SCS is powered by an
uninterruptable power source (see warning). Refer to the release notes for detailed instructions on
the firmware upgrade of 4200-SCS instruments including the specific versions required for each
instrument. See “Accessing the release notes” on page 1-46 for more information.
WARNING Make sure to power the 4200-SCS with an uninterruptable power supply
during the firmware upgrade process. This is important because an
interruption of the firmware upgrade process may damage an instrument card.
To upgrade the firmware, run the upgrade utility from a command prompt:
