I/O Expansion
In the maximal configuration, up to 110 I/Os can be connected to the ACE3600, by using two
expansion LAN switches on the main frame and thirteen I/O expansion frames. See Figure 16-
3.

I/O Expansion Frame
An I/O expansion frame must always include an expansion module to enable the CPU in the
main frame to communicate with and control the expansion frame and its I/O modules. The
expansion module is provided with each expansion frame model.
Like the ACE3600 main frame, the I/O expansion frame can contain 3, 5, 7 or 8 I/O slots. The
expansion frame is compatible with the existing chassis and housing options.
I/O Expansion Power
The choice of power supplies for a system with I/O expansion is determined by the specific
configuration and the power requirements of the system.
In a co-located system where the power supply on the main frame feeds the I/O expansion
frame, a low-tier power supply cannot serve as the main power supply.
In a distributed system where the power supply on the I/O expansion frame is not connected to
the main frame, any power supply modules can be used which suit the power requirements of
the system. When applicable, it is recommended to have an external single power on/off
