Connections between Site Controller and XHUB Controller
Figure 61: Connections Between Site Controller and XHUB Controller on page 120 illustrates how two
SCs are connected to two XHUBs. SC 1/Exp Cab is connected to the XHUB 1/Prime Cab and SC
2/Exp Cab is connected to XHUB 2/Prime Cab. Connections between the Site Controller and the
XHUB are the same, if redundant Site Controller is being used.
NOTICE: Ethernet cables from Prime Cabinet to Expansion Cabinet are routed through the
conjunction hole on the side of the cabinets.

Power Connection to the XHUB Controllers
Along with the XHUB Controller, the concept of Redundant PSU power is introduced. The power from
PSU 3/DC Out is split into two, supplying power to both XHUBs through the Power 3 connector. The
power from PSU 4/DC Out is also split into two, bringing power through the Power 4 connector on both
XHUBs.
