3.2 Fabric Interface
3.2.1 Common Options
MCH Fabric Port 1 is routed to AMC 1 Port 0.
MCH Fabric Port 2 is routed to AMC 2 Port 0.
MCH Fabric Port 3 is routed to AMC 1 Port 1.
MCH Fabric Port 4 is routed to AMC 2 Port 1.
AMC Ports 2 and 3 are direct slot to slot connections between both AMC slots.
3.2.2 Fat Pipe
AMC slots Port [4:7] are direct slot to slot connections between both AMC slots.
3.2.3 Extended Fat Pipe
AMC slots Port [8:11] are direct slot to slot connections between both AMC slots.
3.3 Intelligent Platform Management Bus (IPMB)
MicroTCA uses an Intelligent Platform Management Bus (IPMB) for management
communications.
3.3.1 IPMB-L
Radial IPMB from MCH to both AMCs.
3.4 Power Management
The integrated power management circuitry on the backplane provides 12 V payload power
distribution branches to the AMC Slots. It also generates the 3.3 V management power and
distributes it to all slots.
The current to the AMC slots is limited to:
•8A(PayloadPower)
• 250 mA (Management Power)
