the shelf.

Removing a Redundant IOC
To remove one IOC when two IOCs are in a shelf, use the following procedure:
1. Issue the following command to take the IOC out of service:
Type
set ioc-state disable IOC2 and press Enter.
2. Attach a wrist grounding strap and connect it to the TimeCreator 1000 chassis.
Warning: To avoid possible electrostatic damage to the IOC, place it
in a static-free bag or on a static-free surface.
Note: To avoid generating unnecessary alarms, be sure to take the
IOC out of service before removing it.
Caution: To avoid a loss of output signals, do not take the only IOC in
a shelf out of service.
Note: An IOC that is out of service cannot be selected to generate or
monitor outputs. An out-of-service IOC does not generate alarms.
