Hardware Version: V2
Firmware Version: 2.0.0 Build 20160922 Rel.68676(s)

Our company has three of these swicthes: T1600G-28TS 2.0 (aka TL-SG2424), Hardware Verson 2.0

(Emphasizing the HW version as it appears to be quite important in this case.)

 

Nowadays modern browsers refuse to connect to the Admin UI via HTTPS:

 


Also, accessing any of the switches via ssh also fails:

 

user@host:~$ ssh admin@10.11.12.13
Unable to negotiate with 10.11.12.13 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

 

The product page is here: https://www.tp-link.com/us/business-networking/smart-switch/t1600g-28ts/

The Support page is here: https://www.tp-link.com/us/support/download/t1600g-28ts/

 

Please note that for HW V2 there is nothing on the main page, as if it never existed, and the support page does have an option for V2, but it seems as no any firmware upgrade has ever been released for V2.


Telnet and HTTP are not acceptable options for us to communicate to these swicthes.

 

Questions:

 

- Does anyone know why has T1600/TL-2424 V2 been abandoned? What was wrong with it? IT works just fine (except for the aged firmweare)!

- Is there any chance to get updated firmware for these swicthes?

- Any chance for V3 firmware to be adapted to work for V2?


Thanks for any hints! Your help is highly appreciated.

I find this model EOL(End of life) on TP-Link's homepage. So I don't think there will be firmware update on this model soon...I guess it's the same for other brands.

 

V2 and V3 are using different chip so you can't upgrade the V3 firmware on the V2 switch. Maybe that why V2 is EOL, because there is no chip for the switch.

@Yannie : Thank you for your reply! I see, the chip being different from V3 (and probbaly from V1 as well I guess) helps sort this out.

 

Have a great day!

@ya55en You can likely still connect to the switches CLI with SSH if desired, you just have to accept some down-graded protocols to do so depending on what version of SSH you are running from the client side

 

For example: ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithm=+ssh-des -oCiphers=+aes128-cbc admin@10.11.12.13
