and correct the fault. Refer to Communication
Server 1000M and Meridian 1 Large System
Maintenance (NN43021-700) ().
Refer to Software Input Output Administration
(NN43001-611) () for a list of all the HEX codes.
Based on the maintenance display codes
description, take the appropriate action and
resolve the problem.
Reinsert the card and observe the self-test
codes. Refer to Software Input Output
Administration (NN43001-611) () for a list of
all self-test codes and their description. If the
problem remains, replace the card.
