Cubix ERS/FT II Systems
ERS/FT II Systems are rack mount or desktop systems that can hold up to eight independent computers. Each computer consists of a BC Series plug-in computer and additional slots in the group assigned to that computer. More on groups later!
The above photo shows a typical system with five BC Series plug-in computers (five independent computers). Each computer can be independently powered on or off, or reset with controls on the front panel.

Backplane
The key to flexibility in Cubix Systems is the backplane. It is installed in the bottom of the system, and determines how many BC Series computers can be installed, and what bus or bus's are supported (ISA, EISA, or PCI).
The above photo shows a "8 x 2 ISA " backplane. The 8 signifies the number of groups, the 2 signifies the number of slots per group, and ISA specifies the Bus type.
With this backplane, you can install up to 8 BC series computers. Each group will contain the plug-in computer and one additional slot for third party boards, such as an internal modem, or fax board.
Each group with a BC series plug-in computer becomes an independent computer in the system.

Backplane Configurations
To increase the number of available configurations, some system backplanes can be reconfigured for a different number of groups, and slots per group. This is done by using shunt slots and shunt boards.
In the picture above, notice the black slots. They are ISA slots for the plug-in motherboards. Each group of ISA slots is separated by a brown connector called a shunt slot.
If the shunt slot is empty, there is no physical connection between the groups on either side of the shunt slot.
If a shunt board is installed in a shunt slot, the groups on either side of the shunt slot, are now physically combined into one group.
For example, if a shunt board is installed between group 1 and group 2 on a 8x2 ISA backplane:
Group 1 would now have 4 available slots instead of two.
The backplane would now have 7 groups (1 group of 4 slots and 6 groups of 2 slots).
Note: Not all backplanes can be reconfigured! If you do not have shunt slots BETWEEN the groups on the backplane, then it is a fixed configuration that cannot be changed.

Multiplexor
A multiplexor is built into the system to control all the BC Series plug-in motherboards. The multiplexor allows you to:
Power individual computers off or on.
Reset individual computers.
Share a common floppy disk drive, monitor, mouse and keyboard.
Important Note: To share a mouse between the independent computers installed in a system, , you must use a Logitech compatible mouse and install the Cubix mouse driver on each computer in the system. Mouse drivers are available on the BC Series Installation diskette for DOS, Windows 3.1, Windows 95 and Windows NT.

Disk Drive Bay
Hard disk drives for the independent computers in the system are installed in the Disk Drive Bay in the front of the system, under the two system fans.
There are two cables on each hard drive. The ribbon cable connects to either the IDE or SCSI port on the BC series plug-in motherboard, depending on the drive type.
The power cable connects to the system backplane. It must be plugged into the power connector with the same group number as the BC series plug-in motherboard that the ribbon cable is connected to.

The power supply bay is located on the right side of the system when viewing the front of the enclosure. This bay houses the single (ERS II) or dual (ERS/FT II) 375 watt power supplies. The purpose of the dual supplies in the ERS/FT II is to provide fault tolerance in the event of a single power supply failure. Fault tolerance is further supported by separate power input receptacles which allow each supply to be powered by a separate power source.

The IES (Intelligent Environmental Sensor) provides management functions for the Series II Systems. The IES is integrated into ERS/FT II Systems as a printed circuit board installed directly in front of the mux board. In the ERS II, a separate IES module may be installed in one of the slots on the backplane in the processor bay.
What's in your System
Because of all the different backplanes available, and the configuration options, it may be hard to tell what is installed in your system. So how do you find out?
First, push the BC Group (up or down) button on the front panel. This will cycle through each installed BC Series plug-in motherboard, and display the group number where it is installed. This will tell you how many computers are installed in the system.
Second, remove the top cover, and look at the backplane. Each group on the backplane will be labeled on the board.
Third, look for installed shunt boards. If you have shunt boards installed between groups, then the groups on either side of the shunt have been combined into a single group.
Fourth, look at the BC Series plug-in motherboards. They are usually installed in the left slot of the group, and have ribbon cables on the top of the boards, connected to the system multiplexor.
Fifth, look at the slot power LED bar behind the two system fans. If the system configuration has not been changed (still factory configured). The bar will show the group and slot configuration.
