Chapter 6 Maintaining and Troubleshooting the TimeProvider

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.

5. The COMPLD message appears after a successful transfer.

Upgrading One IOC From the Other
To upgrade the software in one IOC to match the software in the other IOC, issue 
the command:

ACT-SWDL::IOCn:TP1000; 

where n = 1 or 2, and identifies the IOC that receives the software from the other 
IOC

You cannot upgrade the software in the Active IOC.
