4.7 APC Silcon Triple Chassis
The APC Silcon Triple Chassis is an American Power Conversion (APC) external management
peripheral that allows you to use monitoring and control management peripherals with your
APC Silcon series UPS. The retrofit model is for use with Silcon series UPSs that are not
equipped with a 24 VDC power port.

Do not connect a computer to any APC Silcon Triple Chassis port using a straight-through
extension cable. Use the communications cable provided with the APC Silcon Triple Chassis.
Connections using a cable made by any other manufacturer may cause damage or improper
operation of the APC Silcon Triple Chassis, the UPS, or the computer.
