4. Retrieve the contents of the IOC memory stored in the IMC by issuing the
following command.
CPY-MEM:::::IMC,IOC,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.
If you have not stored the contents of the IOC memory in the IMC, then provision
the IOC using the procedures and commands described in Chapter 4,
Provisioning the TimeProvider.
5. Issue the following TL1 command to place the IOC in service:
ED-EQPT::IOC1:::IOCSTATE=INSRV;
6. Install the IOC into the right slot of the shelf and tighten the captive retaining
screws. This IOC will become the Standby IOC.
7. Wait for the IOC to reboot and qualify the reference inputs. During this time the
Active IOC updates the new IOC’s memory with current values.
8. Issue the following TL1 command to place the Standby IOC in service:
