[ 3Com - 3c588]

Despite appearances, the 3c588 is just a modular repeater, not a switch. 



The BNC module has a jumper internally to terminate the segment so you do not have to use a TEE piece. 
It looks like a screw is available to earth the segment too.  The partition LED light comes
on solid if the segment is partioned off because of a fault, either a short or an open circuit, basically any deviation from the expected 25 Ohms (a 50 ohm terminator at …</description>

        <description>CASE / Cray System Centre ethernet hub/switch


This network device is rather more impressive than it actually is, but it is still quite interesting. It is labelled on the front panel as being made by CASE technology (who seem to have gone out of business so long ago I cannot find a trace), but the internal blade pcbs are labelled as being made by CRAY Communications or Networks and refers to Denmark Copyright 1982.000</description>

Definately a Retro project, this is a 10 MB/s catalyst switch base unit with an expansion module called a “Flex Slot” above.
In fact this is so old that Cisco have a new Catalyst 3100 product (&lt;https://www.cisco.com/c/en/us/support/switches/catalyst-ie3100-rugged-series/series.html&gt;), a rugged industrial style switch with 1GB/s SFPs fitted!! Wow!! From 10MB/s to 1GB/s!000</description>
