Jumpers; Dsbe/S Sbus Card Jumper - Sun Microsystems SPARCcenter 2000 Service Manual

B.1 DSBE/S SBus Card Jumper

Jumpers

Use this appendix to set or identify jumpers on:
•
The DSBE/S SBus card
•
The NVSIMM
•
The system board
The Link Integrity Test tests communications between the DSBE/S SBus card
in the server and the nearest network hub. If the test is set differently at the
card and the hub, communication is not possible. (A monitor attached to the
server will display "no carrier" or "not responding" or a similar message).
The test is enabled or disabled through hardware or software settings. To
change the setting through software commands, see Section 3.9, "Enabling and
Disabling the Link Integrity Test," on page 18. Alternatively, the Link Integrity
Test may be set by way of a jumper on the DSBE/S SBus card. The jumper
(J0302) is shown in Figure B-1.
•
To enable the Link Integrity Test, put the shunt in one pin as shown in part A
of Figure B-2. This is the default condition for Sun equipment.
•
To disable the Link Integrity Test, put the shunt over both pins, as shown in
part B of Figure B-2.
