5. The COMPLD message appears after a successful transfer.
6. Restore the contents of the IOC memory from the IMC by issuing the command:
CPY-MEM:::::IMC,IOC,IOC;
Upgrading Redundant IOCs
To avoid output interruptions, the TimeProvider must be in the following state:
îš„ Two installed and communicating IOCs
îš„ Both IOCs are in the Locked mode
îš„ Both IOCs are In Service
îš„ Both IOCs are alarm-free
îš„ One IOC is Active
If any of these conditions are not present, then the outputs are interrupted for up to
30 minutes until the upgraded IOC enters the Locked mode.
To upgrade the software in both IOCs, use the following procedure:
1. Log in to the TimeProvider with an Admin- or Security-level user id and
password.
2. Back up the contents of the IOC memory in the IMC by issuing the command:
CPY-MEM:::::IOC,IMC,IOC;
3. Start the download by issuing the command:
ACT-SWDL::IMC;
The TimeProvider issues an In-Process response, the TL1 connection closes,
and the TimeProvider waits to receive the upgrade software using the Ymodem
protocol.
4. Use a Ymodem file transfer program such as SynCraft to transfer the upgrade
software to the TimeProvider. You must start the transfer within 60 seconds or the
TimeProvider issues a Deny response.
The active IOC (IOC1 for example) goes into Standby mode and the Standby
IOC (IOC2, in this example) goes into Active mode. The new software is loaded
into IOC1, after which it is rebooted and enters the Warm-up mode for up to 30
minutes.
When IOC1 enters the Locked mode, it becomes the Active IOC again (IOC2
goes into Standby). The new software is loaded into IOC2, after which it is
rebooted and enters the Warm-up mode for up to 30 minutes.
