Maintenance Instruction ASB 150 02 > Hot-Swapping Of Boards

## Prerequisites

Boards can only be replaced by boards of the same type, with the same number of individuals. This limitation applies also for changing the number of individuals on an IC-CU-board. Just changing the FECU may cause serious memory allocation problems which may lead to a warmstart of the whole system. New boards shall be inserted in a vacant position only. If the RASC-PC is connected to the system via an AUX-board, this board must not be removed. If RASC is connected via a modem it is not possible to perform any hot swapping action.
