Replacing Output Modules

The TimeProvider supports up to four Output modules on the shelf, and up to four
additional Output modules on the Expansion Panel. A variety of Output modules is
available to support different wiring schemes (see
page 60, for a description of the available Output modules).
To remove an Output module:
1. Disable the outputs on the Output module by issuing the command:
ED-EQPT::OUTg:::OUTSTATE=DISABLE;
where g is the output group you are disabling (A, B, C, or D)
2. Attach a wrist grounding strap and connect it to the TimeProvider chassis.
3. Remove the output connections.
4. Remove the Output module by loosening the captive screws and pulling the
module off the shelf.
Warning: To avoid possible electrostatic damage to the Output
module, place it in a static-free bag or on a static-free surface.
5. Place the module in a static-free bag or on a static-free surface.
