CHAPTER 6: MAINTENANCE
The Modular KVM Matrix Switch contains various components and assemblies that can be maintained. All relevant components
and assemblies are hot swappable and can be removed and exchanged during operation.
The following exchangeable components can be found within the Modular KVM Matrix Switch.
6.1 POWER SUPPLY UNITS
To exchange the power supply units, proceed as follows:
1. Make sure that the power cord cable is removed from the power supply that has to be exchanged.
2. Unlock the locking screw(s).
3. With the power supply units of ACX288 and ACX160, turn the unlocked bracket down.
4. Pull the power supply unit out of the corresponding slot.
5. Push a new or maintained power supply unit into the slot and lock it accordingly.
6. Connect the power cord cable to the power supply unit. It will be recognized by the system and can be used afterwards.
6.2 FAN TRAYS

6.3 CPU BOARD
To exchange the CPU board, proceed as follows:
1. Pull the locking pin slowly out of the CPU board up to the stop. Wait until the CPU board is deregistered from the matrix. The
deregistration will be confirmed by a permanent green light of the status LED #1 on the CPU board (see Section 2.7.1).
2. Remove all cables from the CPU board.
3. Pull the CPU board out of the corresponding slot by using the locking pin.
4. Push a new or maintained CPU board into the slot and lock it accordingly.
A successful registration of the CPU board will be shown by a permanent green flashing of status LED #1.
