Upgrading the Firmware
This command always has a security level of SECURITY.
<aid>
IMC Downloads a new firmware image to the IMC.
If the IMC or IOC provisioning has changed in the newly upgraded firmware, you
may need to issue the CPY-MEM command from an in-service IOC to the IMC
before the IMC is fully functional. See the TimeProvider TL1 Reference Guide for
more details.
IOC Downloads a new firmware image to the IOC.
Symmetricom recommends that redundant IOCs use the same firmware revision.
The Active IOC enters Standby mode, putting the second IOC in Active mode. After
acknowledging the changeover, the IMC starts the firmware transfer to the Standby
IOC.
After the download, the Standby IOC must achieve Lock (CLKLOCK) mode before
changing again to Active mode. The Standby IOC is then upgraded.
If the first IOC upgrade is not successful, the entire process is aborted and an
SROF error message is generated. The IOC restarts with the existing firmware.
IOCm Downloads the IOC firmware image from the Active IOC to the Standby IOC.

This command does not require Ymodem or SynCraft to transfer an image file from
the computer to the TimeProvider.
Sample Command
ACT-SWDL::IMC:TP1000;
If the image transfer takes more than 60 seconds to start, the error response is
SROF and the IMC returns to normal operation. You will need to start the download
process again to perform the upgrade.
If the header information in the referenced file is not correct, the error response is
SROF, followed by a message that says the firmware upgrade was not successful.
If the file header is correct, the TimeProvider responds with a message stating that it
is beginning the firmware upgrade, followed by a message stating the upgrade was
successful.

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
