• A module expansion may only include synchronous digital network interfaces (BRA, PRA) if this
type of card is already incorporated into the main module (synchronization by the main module).
• The same rules apply to the other boards as those which applied to the base module.

8.14.3.4 Adding a third module
• Replace the HSL1 board of the PowerCPU EE/PowerCPU EE C25 board with an HSL2 board.
• Reuse this HSL1 board by placing it on the PowerMEX board of the third module.
In an installation using two modules, the PowerCPU EE/PowerCPU EE C25 (base module) and
PowerMEX (module expansion) boards are fitted with an HSL1 board.
8.14.4 Installation Upgrade
This section outlines the major considerations to be taken into account in the following migrations:
• OXO Connect R2.x or lower to OXO Connect R3.x with PowerCPU EE
• OXO Connect R2.2 to OXO Connect R3.x with PowerCPU EE C25
Migration from OXO Connect R2.2 to OXO Connect R2.2 or higher with PowerCPU EE C25 is not
supported.
Migration must be performed on site, except when there is no hardware change and the PowerCPU
EE/PowerCPU EE C25 remains the system's CPU.
8.14.4.1 On Site Migration
On site migration applies when the CPU is changed (PowerCPU replaced by a PowerCPU EE).
