1.1 General Information
The MIB-3081A is a 6U-sized CT backplane that provides eight CompactPCI slots. One
slot is assigned to the CPU board and seven slots to the peripheral boards. The
MIB-3081A supports front and rear I/O wiring, providing simplified system cabling. The
backplane also complies with PICMG 2.5 Computer Telephony Specification, providing
H.110 CT bus on the P4 connectors.
The MIB-3081A provides 3-pin connector for connecting up to six cooling fans. A 26-pin
connector can be used for connecting an external alarm module (MIC-3924 series) to
detect system internal conditions, such as bus voltages and fan speed. In order to
provide users with a flexible system configuration, the MIC-3081 includes two standard
ATX power connectors to accept up to two ATX power supplies.

2.1 Slot Assignments
The CompactPCI specification defines slot numbering seperating for physical and logical
slots. Each slot has a physical number and a logical number (refer to the CompactPCI
specification version 2.0 R2.1 for further information on slot assignments). The physical
numbers are printed on the backplane, enclosed in circles or triangles, below each slot.
Slot 8, marked by a triangle, is the system slot and can only be used by a CPU board.
The other slots (slot 1~7) are peripheral slots and can be used by peripheral cards.
The logical number of each slot is defined according to the IDSEL signal and the
associated address used to select the slot. Table 2-1shows the system slot and
peripheral slot relationships on the MIB-3081A. Physical slot 8 (system slot) has a
logical number of 1, physical slot 7 has a logical number of 2, physical slot 6 has a
logicalnumber of 3, ..., and physical slot 1 has a logical number of 8. The connectors in
logical slot 1 are designated as 1-P1, 1-P2, 1-P3, 1-P4, and I-P5, from the bottom up.
Nomenclature for connectors in other slots is similar, such as 2-P1, 2-P2, 3-P1, 3-P2,
etc. Connector 1-P1 is a keyed connector providing 32-bit CompactPCI bus between the
system slot and the peripheral slots (2-P1~8-P1). Connector 1-P2 is an un-keyed
connector providing 64-bit CompactPCI bus between the system slot and the peripheral
slots (2-P2~ 8-P2). Connector 2-P4 to 8-P4 are un-keyed connectors which provide
H.110 CT bus used for TDM signals transmission.
Appendix A gives the pin assignment for all the slots on the MIC-3081.

2.2 Connector and Jumper Locations
The MIB-3081A provides connectors and jumpers for users to configure the backplane
for specific application. Table 2-2 gives a brief description to each connector on the
backplane. Figure 2-2 and Figure 2-3illustrate the connector locations of the
MIB-3081A.

2.2.1 Alarm Board Interface (CN8)
The 26-pin connector CN8is an interface for an external monitoring and alarm module,
such as MIC-3924 series, which monitors the conditions of the system. It contains bus
voltages 3.3 V, 5 V, 12 V and -12 V, and utilizes six fan tachometer signals
2.2.2 Fan Module Connector (FAN1 ~ FAN6)
The FAN1 ~ FAN6 connector provides +12 V power for fan operation and accepts the
tachometer output from the fans. It accepts up to six fan signals.
2.2.3 ATX Power Connector (ATX1 and ATX2)
These connectors accept two standard ATX power supplies.
Note: Do not use ATX power supplies and plug-in power modules at the same time.

2.2.4 Power Connectors for Peripherals (CN1and CN2)
The CN1and CN2connectors provide power to the peripherals, such as hard disk drives
or floppy disk drives.
2.2.5 V I/O Voltage Selection (T1 ~ T3)
This jumper is used to select the V I/O voltage. MIB-3081A allows V I/O to be set to
either 5 V or 3.3 V. Since the MIB-3081A default is configured for use with 5 V
CompactPCI boards (blue keyed connectors), once the jumper is set to 3.3 V, the
CompactPCI keys must be changed to 3.3 V at the same time (as yellow keyed
connectors).

2.2.6 Power Switch (CN4)
This connector provides power on/off control of the ATX power supply or the plug-in
power module. If the CompactPCI chassis provides a 2-pin power switch cord, connect
this cord to the CN4 connector and users can control the power on/off by the power
switch. Or users can directly short this connector by a jumper and control the power
on/off by the ATX power supply switch.
2.2.7 LED Status Connector (JP1)
This connector provides digital outputs for the alarm module (MIC-3924) to the chassis
front panel notification used. Three alarm LED (red) and one power status LED (green)
is included for Fan_fail, Power_fail, and Temp_fail for alert notification.

2.3 Ground Configuration
Along the top and bottom of the MIB-3081A are 18 mounting holes. The holes are
arranged in an alternating pattern of chassis (frame) grounded pads and logic
grounded pads. The square pad holes are connected to chassis ground, and the round
pad holes are connected to logic ground. To isolate chassis and logic grounds, install
mounting screws in only square pad mounting holes.
2.4 Computer Telephony Bus
The MIB-3081A provides H.110 CT bus on the P4 connectors, which complies with the
PICMG 2.5 Computer Telephony Specification. The CT bus is routed across the P4
connectors on the peripheral slots. Please refer to Appendix A for pin assignment
information.
2.5 Clock Routing Configuration
The MIB-3081A is configured to comply with the clock routing specified in the
CompactPCI Hot Swap Specification, PICMG 2.1, version 1.0. This Specification
requires that each slot be independently clocked. If users would like to reconfigure the
backplane to comply with the earlier CompactPCI Specification, PICMG 2.0, version 2.1,
which allows the MIB-3081A to be backward compatible with CPUs using shared
clocks, please contact Advantech for help.
