194 / Planning the installation
To use the Upgrade Tool to upgrade from previous versions of
MICS (all versions prior to MICS 4.0), follow these steps:
1. Power down.
2. Disconnect all amphenol cables.
3. Remove the power to the ICS and all associated modules.
Disconnecting the power ensures protection for electronic
components and that the data stored in the feature cartridge
will not be corrupted.
4. Remove your old Norstar MICS software cartridge.
5. This step determines the type of MICS system you will
ultimately upgrade to.
Insert the MICS NVRAM cartridge. See illustration on
page 219.
Insert the PC-card (or Flash card) that came with your
upgrade tool package.
6. Reconnect all amphenol cables.
7. Power up. Wait until display flashing stops. Insert MICS
Card is displayed.
8. Power down.
9. Insert the Modular ICS ROM software cartridge to
perform the final stage of the upgrade to MICS 4.0, 4.1, or
5.0. See Installing the ROM Software Cartridge on page
219 to verify that you are using the proper software
cartridge.
10. Power up.
Modular ICS 6.0 Installer Guide
Ensure that you use the appropriate MICS
upgrade tool when upgrading.
Your Norstar system will cold start and your data
will be lost if the MICS ROM software cartridge
that came in your upgrade tool does not match
your MICS system software.
