5.5.2 Flash Updating
The CRS-300 eliminates the need for updating firmware by physically replacing EPROMs.
Instead, the CRS-300 uses ‘flash memory’ technology internally. This makes software upgrading
very simple, and updates can now be sent via the Internet, E-mail, or on CD.
This section outlines the complete upgrading process as follows:
• New firmware update for upgrading the CRS-300 is transferred to a user-provided PC
intended for Monitor and Control (M&C) of the CRS-300 1:10 Redundancy Switch.
• By simply connecting the CRS-300 to an available serial port on the user-provided PC,
the upgrade can then be performed without opening the CRS-300 chassis.
• Once the firmware update is extracted from the transferred archive file, the upgrade
process is executed via use of a utility program, CCCFlash.EXE.

5.5.2.1 Firmware File Transfer Procedure
1. Identify the reflashable product, firmware number, and version for download.
Using serial remote control, the current CRS-300 firmware revision can be determined with
the following query: <0/ SWR?
2. Create a temporary directory (folder) on the user-provided external PC.
Windows: Select File > New > Folder, then rename the New Folder to "temp" or another
convenient, unused name. Assuming "temp" works, a "c:\temp" folder should now be created.
Note: The c: is the drive letter used in this example. Any valid writable drive letter can be
used.
CMD Prompt: At the command prompt (c:\>), type "mkdir temp” or “MD temp" without
quotes (mkdir and MD stand for make directory). This is the same as creating a new folder
from Windows. There should now be a "c:\temp" subdirectory created (where c: is the drive
letter used in the example).
