Diagnosing the IOC

Compatibility Alarm
If you receive a COMPAT alarm, then one or more of the installed hardware and/or
software components is not compatible with other components. Refer to the Software
Release Notice (097-58001-20) for a list of compatible components and firmware
revision levels. If necessary, update the firmware in one or more components using
the procedures in
Upgrading the Firmware
, on page 181.
Removing the IOC
You can remove either of two IOCs in a shelf without affecting outputs. If you need
to remove the only IOC in a shelf, or remove both IOCs from a shelf, outputs are
interrupted and will resume once one IOC has achieved lock on an input signal.
Removing the Only IOC
To remove the only IOC in a shelf, use the following procedure. Output signals will
be interrupted; they will resume once the IOC has achieved lock on an input signal.
1.
Save the contents of the IOC memory in the IMC by issuing the following command
:
CPY-MEM:::::IOC,IMC,IOC;
This command may take more than two seconds to execute; if it does, then the
In-Process response is issued. See the TimeProvider TL1 Reference Guide for
more information on the CPY-MEM command.
2. Issue the following command to take the IOC out of service:
ED-EQPT::IOCm:::IOCSTATE=OOSRV;
where m is 1 or 2, and determines which IOC you take out of service.
3. Attach a wrist grounding strap and connect it to the TimeProvider chassis.
4. Loosen the captive retaining screws and pull out on them to unseat the IOC from
the shelf.
5. Place the IOC in a static-free bag or on a static-free surface.
6. Install a new IOC using the appropriate procedure in Replacing the IOC, on page
150.
Warning: To avoid possible electrostatic damage to the IOC,
place it in a static-free bag or on a static-free surface.
