REPAIR PHILOSOPHY
Field repair of the LANIC cards is limited to the replacement of the card itself. To exchange a LANIC
card, remove it from the system and prepare it for reshipment to Hewlett-Packard in accordance with the
instructions presented in Section 2.
SELF-TEST
A self-test is included in ROM on the LANIC card. The self-test runs at power-on, when the LANIC
TEST (RESET) switch on the LANIC card is pressed, or when invoked by the LAN diagnostic.
NOTE
The self -test consists of several tests which check approximately half the
circuitry on the LANIC card as well as performing a simple test of the AUI
cable and the MAU. The LAN/3000 link diagnostic
must
be run to
perform a complete test of the LANIC card. See the
LAN/3000 Diagnostic
and Troubleshooting Guide, part number 30242-90003
for a description of
the diagnostic.
I
CAUTION
I
PRESSING THE LANIC TEST SWITCH PERFORMS A HARD RESET ON
THE
LANIC
CARD
BEFORE
THE
SELF-TEST
IS
INITIATED.
NETWORKING OPERATIONS IN PROGRESS WILL BE DISRUPTED BY
PRESSING THE RESET SWITCH. ONCE SELF-TEST HAS STARTED,
ALLOW IT TO COMPLETE PRIOR TO PRESSING THE SWITCH AGAIN.
PRESSING THE SELF-TEST SWITCH WHEN THE LINK IS OPEN OR
WHILE SELF-TEST IS ACTIVE HAS A SLIGHT POSSIBILITY OF
CRASHING THE SYSTEM.
