You can upgrade the Logic Solver and SISNet Repeaters using the Controller and I/O Upgrade Utility. Be sure that the Logic Solver is decommissioned and the controller with which it is communicating is commissioned before starting the upgrade process. The controller must be commissioned, not necessarily configured/downloaded before starting the upgrade. If you are upgrading a redundant Logic Solver, be sure to upgrade both cards in the redundant pair to the same revision.
Upgrading a single Logic Solver can take between five and ten minutes.
SISNet Repeaters appear in slots 65 and 66 on the screen that lists the available SIS components to upgrade. Scroll the list to find SISNet Repeaters.
