Upgrading the System
Using a PC Card
10-5
7. Follow the procedures below:
a. If you are upgrading from Release 1.0 to Release 2.0, power down and remove the PC
upgrade card.
b. If you are upgrading to Release 3.0 or later, do not remove the PC card. The card
automatically converts to a backup/restore and remote access card. If you removed other
PC cards, PVM or ASA/DXD, for example, power down the system and reinstall the PC
cards after the upgrade is complete.
8. If you have a 2-slot carrier or a stand-alone configuration, you are finished with this procedure.
If you have a 5-slot carrier, continue with Step 9.
9. Make sure all modules are seated properly.
10. If you have a 5-slot carrier and Release 4.0 or later:
a. Position the carrier cover over the modules so that the openings on the top of the carrier
cover align correctly with the tabs at the top of the installed 5-slot carrier and modules.
b. Rotate the carrier cover into position so that it aligns correctly with the thumb screw
opening on the bottom of the carrier.
c. Tighten the thumb screw. To ensure proper alignment and safe operation, tighten the
thumb screw securely.
If you have a system of Release 3.0 or earlier:
a. Grasp the cover by its upper edges and hold it squarely over the control unit (see
Figure 10-3). Place the cover over the modules and make sure it fits firmly in place.
Figure 10-3. Replacing the Cover
b. Tighten the screw on the lower front of the cover.
