Functional Description
iVPX7225 Installation and Use (6806800S11C) 52
4.5 Ethernet Interfaces
iVPX7225 provides two 1000BASE-BX ports that are routed to the VPX backplane for operation
as Ultra Thin Pipes per VITA 65 SLT3-PAY-2F2U-14.2.3 and SLT3-PAY-1F1F2U-14.2.4 slot
profiles.
Ethernet is implemented using an Intel 82580 Gigabit Ethernet controller onboard the
iVPX7225. PCH PCIe Port 0 (lanes 1-4, configured as x4) is routed to the 82580. When accessed
through RTM, in a non-switch backplane configuration, dual PHYs onboard the iVPX7225 RTM
convert these control plane interfaces to 1000BASE-T. These are accessible at the dual RJ-45
RTM planar connector, J101.
Because the Ethernet interface to the backplane is 1000Base-BX, the associated 1000Base-
T ports on the RTM are fixed at 1000Mbit, and cannot auto-negotiate down to 10/100Mbit.
