Upgrading the Firmware

You can upgrade the firmware in the IMC or IOC using TL1 commands and software
available from Symmetricom. Only users with Admin- or Security-level access can
execute the command. The command places the management module in the
firmware download mode and terminates all sessions except the session performing
the upgrade. During the upgrade process, no new sessions are allowed. Refer to
the TL1 Reference Guide for details on the upgrade process.
Caution: To avoid a possible service call, do not issue a command to
the TimeProvider, do not remove power from the TimeProvider, and
do not remove an IOC or IMC from the shelf during the upgrade
process. Doing so could corrupt the flash memory in a card, disabling
the TimeProvider.
Use the following TL1 command to download the firmware.
ACT-SWDL:[<tid>]:<aid>:[<ctag>];
After you issue the command, you have 60 seconds to begin transferring the
upgrade file using the Ymodem transfer protocol. If you do not start the transfer
within 60 seconds, the command times out and you will have to issue the
command again. You can use the SynCraft application to transfer the upgrade file.
The system downloads the firmware using the Ymodem protocol; if the IMC
firmware is upgraded, the processor in the IMC is reset.
