4.4.8Perform Firmware/Software Upgrade

You can upgrade the firmware/software of the PMC-CGM via the MIB. The firmware/software upgrade is done by downloading an image from a TFTP server and programming it into the inactive partition of the boot flash (that means not the one which is currently running) which is split into two partitions of 32MB each. By default, only one of the two partitions (the active partition) is accessible.

Upgrading the firmware/software

To upgrade the firmware/software, proceed as follows:

1.Start SNMP manager or MIB browser.

2.Connect to the PMC-CGM using one of its IP addresses.

3.Go to object cgmFwUpdateHost OID: .1.3.6.1.4.1.3656.8152.1.3.26.0.

4.Enter the IP address of the TFTP server that contains the new image.

5.Go to object cgmFwUpdateFile OID:.1.3.6.1.4.1.3656.8152.1.3.27.0.

6.Enter the file that contains the new image.

7.Go to object cgmFwUpdateMd5 OID:.1.3.6.1.4.1.3656.8152.1.3.28.0.
