2.3.2 1000BaseKX Ethernet Channels 1 and 2 Connectors (J4 & J5)
The
IPN250RTM
supports
two

2.3.3 PCI Express Interface Connectors (J6, J7)
User
‐
defined
connections
include
4
differential
pairs
of
PCIe.
These
are
connected
as
two
ports
of
1
‐
lane
PCIe
on
the
IPN250RTM.
NOTE
The PCIe differential pairs can only be used as two 1-lane ports; they cannot be used together to
form a single 2-lane PCIe port.
J6
and
J7
provide
the
PCIe
interfaces
via
two

cable
connectors.
On
both
connectors,
only
the
first
lane
is
populated;
the
other
lanes
have
their
positive/negative
pairs
connected
together
via
100
terminating
resistors,
in
accordance
with
the
PCIe
cabling
standard.
J6
provides
lane
1
and
J7
provides
lane
2.
All
power
and
management
signals
are
unused,
and
have
been
grounded
via
100
resistors
to
maximize
the
noise
immunity
of
the
cable.
