Chapter 6 Maintaining and Troubleshooting the TimeProvider

To upgrade the software in the IMC, use the following procedure. You must have the 
upgrade software available on diskette or other media, as well as a Ymodem 
file-transfer program such as SynCraft available before you begin the procedure. 
Outputs are not affected during the IMC upgrade procedure.

1. Log in to the TimeProvider with an Admin- or Security-level user id and 

password.

2. Back up the contents of the IMC memory in an IOC by issuing the following 

command:

CPY-MEM:::::IMC,IOC,IMC;

3. To start the download, issue the command

ACT-SWDL::IMC:TP1000; 

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 TimeProvider validates the received file, updates the flash memory and 
reboots the IMC if the file is valid. If the file is not valid, the TimeProvider issues a 
Deny response.

5. The COMPLD message appears after a successful transfer.

This section contains procedures for upgrading a shelf with a single IOC and for 
upgrading a shelf with redundant IOCs.

Upgrading Single IOCs
To upgrade the software in a single IOC, use the procedure in this section. Outputs 
from the TimeProvider will be interrupted for up to 30 minutes until the upgraded 
IOC enters the Locked mode.

1. Log in to the TimeProvider with an Admin- or Security-level user id and 

password.

2. Save the contents of the IOC memory in the IMC by issuing the command:

CPY-MEM:::::IOC,IMC,IOC;
