Ethernet Ports
The
XSR
comes
equipped
with
two
Ethernet
(LAN)
ports
that
support
full
‐
duplex
10
or
100
Mbps
transmission.
Both
ports
conform
to
IEEE
802.3
standards
with
8
‐
pin
modular
RJ
‐
45
connectors.
A
cross
‐
over
cable
is
used
to
connect
the
XSR
directly
to
a
PC
or
uplink
port
while
a
straight
‐
through
cable
is
used
to
attach
the
router
to
a
hub
or
switch.

single
‐
port
Copper
or
Fiber
‐
optic
Ethernet
NIMs,
shown
in
Figure A
‐

,
provide
interfaces
for
half

full
‐
duplex
10/100Base
‐
T
or
fiber
‐
optic
100Base
‐
F
transmission
over
LAN
or
WAN
networks,
respectively.
The
Copper
Ethernet
NIM
incorporates
a
standard
8
‐
pin
modular
RJ
‐
45
connector
and
the
Fiber
‐
optic
Ethernet
NIM
has
an
MT
‐
RJ
multi
‐
mode
interface.
Both
NIMs
conform
to
IEEE
802.3
and
PCI
2.2
standards.
