28 VMIVME-7807/VME-7807RC Hardware Reference Manual
2.5 Ethernet Controller
The
network
capability
is
provided
by
the
Intel
82546EB
for
the
VMIVME
‐
7807
or
the
Intel
82546GB
for
the
VME
‐
7807RC
Ethernet
Controller
for
Gigabit
Ethernet
and
the
Intel
82551
10/100
Mbit
Ethernet.
These
Ethernet
controllers
are
PCI
bus
based
and
are
software
configurable.
The
VMIVME
‐
7807/VME
‐
7807RC
support
10Base
‐
T,
100Base
‐
TX
and
1000Base
‐
T
Ethernet.
10Base-T
A
network
based
on
the
10Base
‐
T
standard
uses
unshielded
twisted
‐
pair
cables,
providing
an
economical
solution
to
networking
by
allowing
the
use
of
existing
telephone
wiring
and
connectors.
The
RJ45
connector
is
used
with
the
10Base
‐
T
standard.
10Base
‐
T
has
a
maximum
length
of
100
meters.
100Base-TX
The
VMIVME
‐
7807/VME
‐
7807RC
also
support
the
100Base
‐
TX
Ethernet.
A
network
based
on
a
100Base
‐
TX
standard
uses
unshielded
twisted
‐
pair
cables
and
an
RJ45
connector.
100Base
‐
TX
has
a
maximum
length
of
100
meters.
1000Base-T
The
VMIVME
‐
7807/VME
‐
7807RC
support
1000Base
‐
T
Ethernet
using
the
Intel
82546EB
for
the
VMIVME
‐
7807
or
the
Intel
82546GB
for
the
VME
‐
7807RC
dual
Ethernet
controller.
The
interface
uses
shielded
cables
with
four
pairs
of
conductors,
along
with
an
RJ45
connector
on
the
front
panel
or
routed
to
the
VME
P2
connector.
The
Gigabit
Ethernet
is
also
available
with
the
optional
VITA
31.1
routed
out
of
the
optional
P0
connector.
NOTE
Ethernet activity is noted on the front panel LEDs by a blinking yellow LED. The yellow LED will be on
continuously when the Ethernet port is linked but with no activity.
2.6 Video Graphics Adapter
The
SVGA
port
on
the
VMIVME
‐
7807/VME
‐
7807RC
is
controlled
by
the
Intel
855GME
Graphic
and
Memory
Controller
Hub
(GMCH).
The
GMCH
is
hardware
and
BIOS
compatible
with
the
