SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
Repair procedures are limited to module replacement. If an
INNIS01 or INNPM11 module fails, remove and replace it with
another. Verify that the replacement module dipswitch and
jumper settings are the same as those of the failed module.
NOTE: Do not remove interface modules under power unless mod-
ule operation has been halted.
MODULE REPLACEMENT PROCEDURE
Follow Steps one through five to replace INNIS01 and INNPM11
modules. Observe the steps listed under
SPECIAL HANDLING
in Section 3 when handling interface modules.
1. Turn the two latching screws on the defective interface
module ½-turn either way to release them.
2. Grasp the screws and slide out the module.
3. Set any dipswitches and jumpers on the replacement mod-
ule to match the settings of the removed module.
4. Hold the module by the faceplate and slide it into its
assigned slot; push until the rear edges of the module are
firmly seated in the backplane connectors.
5. Turn the two latching screws on the module ½-turn to lock
the module in place. A module is locked into the module
mounting unit when the open end of the slots on the latching
screws faces the center of the module faceplate.
