Saga Telecom Industrial Switch

(Model STI-42424XGGPM-4BT)STI-42424XGGPM- 4BT Switch

Price: £588 + import charges), August 2025

This was bought to replace the buggy Linovision POE-SW708GM-DC12V switch.

A few months ago, I got a rather generic email to our company mailbox, from "Saga Telecom", who I've never heard of before. I have never bought anything from a "spam" email (company or personal!) before, and never had any dealings with Saga Telecom, but their devices looked interesting, so I asked for more information:

The salesman was very helpful, and when I mentioned about the SNMP limitations with the Linovision device, he sent me a PDF showing all the SNMP OIDs the device supported, which was reassuring.

I bought the L3 version as I thought I might need the routing capability, and it has more RJ45 and SFP ports, so it's not quite the same as the Linovision.

The price wasn't much different between 16 ports and 24 ports, so I was slightly pushed to go for the 24-port version.

There is a similar version that has I/O ports for relays etc, but that version was not out of development at the time, and I although it could have been useful, I didn't know how long it would have been before it would be available.

The UI is nicer and less buggy than the Linovision, although slightly more complicated.

There is a nice function that as you select more and more of the menu options on the left, they show up as tabs in the main UI section. This means you can easily go between different screens that you use often.

Connecting the DC cables is nice and easy, you just push the wires into the holes, and use a flat-headed screwdriver to push on a little button to release them again. While they may not be as strong as proper screw-clamp terminals, they seemed to be pretty solid when I pulled on the wires afterwards.

Pros

  • Supports 10mbps half duplex, unlike the LInovision version
  • Well-designed UI
  • Backup results in a file with plain text commands (similar in structure to a Cisco config)

Cons

  • UI doesn't remember the # of lines to display
  • SFP ports doesn't autodetect speed, and default to 10gbps. I had to manually select 1gps for my 1gps Cisco SFP
