SRM-6 Operation & Diagnostics
Firmware Download Guidelines
•
The Firmware Download function performed at the terminal interface allows you to download
new operating firmware into the unit. New firmware is typically downloaded when GDC
releases a new version of firmware that improves performance or adds new features.
It is strongly suggested that the user should copy the Active firmware to Standby firmware
prior to downloading new firmware.
•
The SRM-6 accommodates Active and Standby firmware. Newly downloaded firmware is first
stored as the Active Revision. You can switch between Active and Standby firmware as needed.
•
When firmware is changed, the SRM-6 will not need to be reconfigured since the EEPROM
saves the configuration.
Firmware Download Procedures
Firmware downloads are performed via Trivial File Transfer Protocol (TFTP). Keep the Firmware
Download screen on display in order to monitor progress and any error messages.
1. At the SRM-6 Firmware Download submenu, select the Download Mode as [2] or [3].
Either of these selections will automatically enable all downloading to the unit.
2. Initiate a TFTP session using the IP of the SCM.
3. At the TFTP prompt, type bin and then press Enter. This causes the transfer to take place
in binary mode.
4. Type put [firmware filename] [address & product code] and the press Enter key to
initiate the actual transfer.
The [firmware filename] is provided with the firmware that is to be downloaded.
The address portion of [address & product code] is the slot/line/drop address when you are
downloading to a single unit.
Note
Refer to
Figure 3-2
5. If the Download Mode is [2] Enable Downloads and Store Zipped, the
firmware download procedure is complete. The newly downloaded firmware is stored as
Active Firmware until you reboot the SRM-6 via a power up/down, or when a soft reset is
performed.
If Download Mode is [3] Enable Downloads, Unzip and Execute, the unit
continues with the process of placing the newly downloading firmware into service.
6. As the unit executes either newly downloaded firmware or firmware switched from Standby to
Active, the Power On Self Test is performed.
7. When the LEDs return to their normal operating states, the unit has resumed operation using
the newly activated firmware.
