ZENITH RH - Firmware Release Notes
Firmware for units operating in 10-24 GHz bands.

Release 2.0.20.0
2024-10-11
• New features:
○ The LSP function has been extended to include the ability to shut down Ethernet port (Link down
/ SFP off).

Release 2.0.15.0
2024-02-09
• New features:

■ Added Total purge option, which deletes all user data in the unit including all logs and SW keys
○ The Tools > Maintenance > Backup screen has been simplified and made clearer
○ The LSP function has been extended by the possibility of interconnecting ETH ports when it is
activated. This function is subject to further modifications.
○ SFP module status extended
• Fixed bugs:
○ If the unit is overwhelmed by requests for new connections to management, these are rejected to
avoid CPU congestion of the unit
○ Fixed listing of ATU tables for various FIDs
○ Fixed the formatting of the listing on the header bar when the LSP function is enabled
○ Fixed LSP behavior after bandwidth change

Release 2.0.14.0
2023-12-07

ing. It is useful in situations when internal switch configuration does not enable access to the Remote
unit IP (e.g. when two ETH ports are completely separated in order to serve different customers).
○ Faster ATPC reaction (better adaptation to sudden weather changes)
○ TX mute (possibility to suppress radio transmission)
○ Default WiFi channels are 5 and 9 (different for L and U unit)
• Fixed bugs:
○ Minor SW fixes and improvements (SNMP alarm)
○ Minor web interface fixes
• Known issues:
○ FW versions 2.x.x.0 are not over-the-air compatible with older FW versions 1.x.x.0 as a consequence
of the serial number system redesign. It is necessary to install the same major FW version in both
units forming a microwave link.
