Firmware Version.
This shows 97(x). Each numeric firmware edition has a compiled version for
letters (o, n, z, x) which indicates compatibility with your particular hardware revision. When
upgrading, the version letter will remain the same. For example, 94(z) upgrades to 97(z). Only
consider upgrading after you have performed other troubleshooting steps and read the version
notes on-line. Save your configuration settings before uploading new firmware. Uploading new
firmware returns all operational parameters to their defaults.
