CAUTION
I
SOME OF THE COMPONENTS USED IN THIS PRODUCT ARE
SUSCEPTIBLE TO DAMAGE BY STATIC DISCHARGE. REFER TO THE
SAFETY CONSIDERATIONS INFORMATION AT THE FRONT OF THIS
MANUAL BEFORE HANDLING THE CARD.
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.
N(JTE
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
ThinMAU.
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.
