Upgrading the Firmware

Upgrading the IMC

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.

Upgrading the IOC

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;
