4.6. Firmware Upgrade
As device always strives to achieve total customer satisfaction, new features
and functions are designed from time to time. To have these new functions in your 600AG serial, you
will need to upgrade the firmware.
Please note before performing firmware upgrade:
- Certain versions of firmware are non-interoperable with other versions. Please confirm the
interoperability of the new firmware with the existing one in your system.
- If the APs are upgraded through a daisy chain, please ensure the AP furthest away is upgraded
first. As not all the newer version firmware is interoperable with the older one. Also if you upgrade
a very old version firmware to a very new one, the configuration of the AP might be set to factory
default and make the AP no longer in the same net scope as the existing daisy chain.
- Not all the new version firmware can be downgraded to the previous one. The minimum
downgradeable version is shown by typing "ver" in SMT-45 Command Line.
The easiest way to upgrade 600AG serial is through the use of SMT and Trivial File Transfer
Protocol (TFTP). A PC is made as the TFTP server, and connected to the AP via the DATA IN port on
the PoE unit.
The first step is to configure both the TFTP server (the PC) and the AP to the same net scope,
namely the IP address and subnet mask. Here 192.168.1.11/24 for the PC and 192.168.1.1/24 for
the AP are used as an example to demonstrate the upgrade procedure with TFTP.
The IP address and subnet mask of PC can be either configured through Internet Protocol
(TCP/IP) selection in Network Neighborhood or your usual way. The AP is configured to
with subnet mask of
255.255.255.0
in SMT-12, as shown below:
192.168.1.1
