Testing the IOC Operating Modes

Warm-up Mode

The IOC enters and remains in the Warm-up mode for approximately 30 minutes after you apply power to the shelf, or when you install the IOC into the shelf. The following actions occur when an IOC enters the Warm-up mode:

The Power LED on the IOC flashes green

An event is generated and stored in the event log

To verify that an IOC is in warm-up mode:

1.Apply an appropriate signal to the INP1, INP2, and/or PRS inputs.

2.Visually inspect the Power LED on the appropriate IOC. The LED is flashing green in the Warm-up mode.

3.Type RTRV-ALM::IOC1;(or RTRV-ALM::IOC2;). The TimeProvider responds with a complied message indicating that the designated IOC is in alarm.

Locked Mode

The IOC enters and remains in the locked mode after it has completed the warm-up cycle. The following actions occur when an IOC enters the Locked mode:

The Power LED on the IOC is green

An event is generated and stored in the event log

To verify that an IOC is in locked mode:

1.Visually inspect the Power LED on the appropriate IOC. The LED is continually green when the IOC is tracking at least one input.

2.Type RTRV-LOG::IOC1:::EVT; (or RTRV-LOG::IOC2:::EVT;). The TimeProvider responds with a list of events related to the specified IOC. Look for the entry with the text “Clock entered lock mode.”
