EL.~emet
transceiver cable.
t
It is a thick cable with IS-pin D connectors
at both ends.
Before going on, make certain that the 8-pin level selection jumper on the CPU
board is properly configured. The board is set at the factory to run a Level 2
Ethernet transceiver, and a jumper will be in place at position
1-2
and position
7--8 when your machine arrives. All transceivers sold by Sun A1icrosystems will
operate properly with a Level 2 Ethernet setting. If you purchased your tran-
sceivers from Sun no level adjustment is necessary. If you are using' a Levell
Ethernet transceiver, you will need to add a jumper across the pin
5--6
position
and leave the other jumpers in place. Perform the/ollowing procedures only
if
you need to place a jumper across the pin
5-6
position and run a Levell Ether-
net transceiver. If the 8-pin level selection jumPe.r is incorrectly configured, your
transceiver may not work properly. E:mmples of transceiver types are listed
below, and the following figures show the board placement, extraction [ever and
Jumper location.
Examples of Level 1 transceivers are the TeL 2010E, 3COrvI 3CIOO, and the
Interlan 1'1"1'10.
Examples ofa Level 2 transceiver are the
TeL
20101.
