Backplane (UBUS) Connection 

To connect the Power PMAC UMAC 465 CPU board to the UBUS backplane, simply slide the 
board into any slot of a UMAC that has a bus connection socket of a UBUS backplane board. It 
does not matter which socket on the backplane board is used, although customarily the CPU 
board is installed in the leftmost slot. 

Getting the P1 backplane connector on the CPU board to mate firmly with the socket on the 
backplane requires some force, but can easily be done by hand. In a standard UMAC rack, getting 
the front plate flush with the front of the rack and turning the front screws firmly will ensure a 
good connection with the backplane. 

The Power PMAC UMAC 465 CPU board gets its electrical power through the UBUS backplane 
board, whether the power comes from a Delta Tau power supply or an external user-provided 
supply. 

Ethernet Connections 

The Power PMAC UMAC 465 CPU board provides two Ethernet ports on the front panel: ETH 0 
and ETH 1 (optional). Both ports can accept standard CAT-5 Ethernet cables with RJ-45 
connectors. Both Ethernet ports provide transformer isolation to prevent ground-loop problems. 

ETH 0 Ethernet Port (P21) 

The “ETH 0” port is the top Ethernet connector on the front panel. It is the primary port for 
communicating with the CPU board from a host computer, as when using the Integrated 
Development Environment (IDE) program running on a Windows

TM

 PC for developing your 

application. 

Note that multiple computers on a single network can independently communicate to the Power 
PMAC CPU board through this single hardware port. 

Optional ETH 1 Ethernet Port (P20) 

The “ETH 1” port is the second-to-top-connector on the front panel. It is the auxiliary Ethernet 
port intended for EtherCAT connectivity. Although not intended for primary host 
communications it can be reprogrammed in the Linux system for Power PMAC communications.  

USB Connections 

The Power PMAC UMAC 465 CPU board provides two USB ports one on the front panel as the 
host port and one device port internal on the PCB. Both provide USB 2.0 protocol 
communications. 

Caution: USB ports are not electrically isolated, so care must be taken in the grounding scheme 
when any separately powered device is connected to one of these ports. Poor-quality 
communications and even permanent component damage is possible when ground loop issues or 
significant differences in ground potential exist. 

USB Host Port (P17) 

The USB “host” port is labeled “USB 1” on the front panel. It is a “Standard-A” format connector 
located just below the Ethernet ports and has a horizontal orientation. With this port, the Power
