 Replace the rack and plug in the PRESSURE module into the new rack. If the
LED on the module does not light up, replace the rack interface card in the
function box.
If a " LQVWHDG RI D QXPHULF and one or more INOP messages are displayed for the

6WHS  Perform a module self-test (See "Performing the M1006A/B Pressure Module Self-
Test" on page 5-42). If the PRESSURE test numerics read exactly the listed values,
proceed to the next step, if not, replace the module.
6WHS  Refer to the following table. Correct the possible cause identified by the INOP
message and verify that the INOP disappears. If the problem still exists, replace the
module.
