Functional Description
3.1
CompactPCI Serial operation
The JetKit-3010 can be operated in a CompactPCI Serial compliant system slot or peripheral slot.
Used in a system slot, the board can control and receive the sideband signals available on the
system slot to control the power management of the rack and the boards. Used in a peripheral
slot, the sideband signals are ignored. In both cases, the I²C System Management Bus is ignored,
but can be implemented on a custom base.
The different usages of the sideband signals are listed in Table 7.

The board automatically detects the slot type by reading the SYSEN# pin and changes the role
accordingly.
The power control options when acting as system board can be configured by using DIP switches
on the board. See chapter 3.5 for more information about the power control options. See Table 34
in chapter 4 for information about the power-related DIP switch settings.
3.2
PCI Express operation
3.2.1
Overview
The PCI Express functionality in CompactPCI Serial is specified in that way that the system board is
the PCI Express complex and the peripheral boards are PCI Express end points.
The JetKit-3010 does not control the PCI Express role according to the slot type plugged. Instead,
the PCI Express root or end point functionality are configured via software of the NVIDIA
®
Xavier™. This allows special configurations e.g. where the JetKit-3010 can be plugged in a
peripheral slot, but still works in PCI Express root mode, e.g. in conjunction with a (non-
transparent) PCI Express switch.
By default, the NVIDIA
®
Xavier™ works in root mode. To configure the NVIDIA
®
Xavier™ for an
end point, consult the NVIDIA
®
