Upgrading Firmware
MGX 8220 shelves are shipped with the latest version of the firmware already pre-loaded.
MGX 8220 firmware upgrades can be downloaded over the network. Firmware and firmware
upgrades for the MGX 8220 shelf are also distributed as a Firmware Media Kit on diskettes. The
contents of the kit are:
• ASC Firmware
• FRSM Firmware
• AUSM Firmware
• CESM Firmware
• FRASM Firmware
• IMATM Firmware
• MIB
TFTP, either through the control port or in-band ATM, is used for downloading firmware from a
workstation into the MGX 8220 modules.
The host uses the following command sequence to download the firmware:
1 tftp <dest_IP_add>
where dest_IP_add is the IP address of the MGX 8220 shelf (Ethernet port, control port, or
in-band VCC depending upon the method of access) receiving the downloaded firmware.
2 tftp> bin
3 tftp> put <source_file_name> <dest_file_name>
where source_file_name is the name of firmware source file and can be any name the user has
chosen to store the firmware.
dest_file_name is the name of the file to which the firmware is to be downloaded, this must be:
MGX 8220_SM_1_<slot#>.FW for downloading to a service module, for example.
MGX 8220_SM_1_9.FW will download firmware to the service module in slot 9.
MGX 8220_SN_1_0.FW will download firmware to the ASC for use in any slot 5 - 14.
MGX 8220_ASC_ACTIVE.FW for downloading to the active ASC.
MGX 8220_ASC_STANDBY.FW for downloading to the standby ASC.
If the download process is disrupted for a timeout or other such errors, restart the TFTP download
process without resetting the MGX 8220 shelf.
If there is a hardware or system failure that requires resetting the card being downloaded, the
firmware must be downloaded using the backup boot procedure. This is a two step procedure.
Step1 Download the boot firmware.
Step2 Download the on-line firmware.
If a backup boot procedure becomes necessary, contact technical support for assistance.
After the firmware file has been transferred completely and successfully, the module should be reset
for the downloaded firmware to take effect.
