For each workstation, plug the
female end of the workstation's transceiver
cable into the
15-pin
D
connector
on
the transceiver,
and
the
male end
of
the
workstation's transceiver cable into the
"ETHERNET"
connector
on
the
workstation's backpanel.

Finally,
J2503
at
board location
K-l
1
on
the
2060
CPU
board must be
set
for
either a
Level
1
or Level
2
Ethernet
transceiver.
For Level 2
transceiver
(which
is
the
way
the
board
arrives
from the factory)
J2503
will
have
its
shunt
out.
Examples
of
a
Level
2
transceiver are the
TCL
20101,
3COM
3001,
3C102,
BICC
1110. Multiplexer boxes such
as Digital
Equipment
Corporation's
DELNI
are
used with a Level 2
transceiver
also. If
you
are
using a
Level
1
Ethernet
transceiver,
pins
7 and
8
of J2503 must have
a
shunt
in.
Examples of Level
1
transceivers are the
TCL
201 OE,
3COM
3000,
and
the Interian
NT10.
NOTE
While these transceivers
are compatible with
Sun
equipment,
it
should be under-
stood that
Sun
does not
guarantee
the
performance of any component not pur-
chased from Sun.
