IBM 8235 022 terminal server - first look 

These were Shiva Lanrover and used IBM Lan Distance server. I used the token ring version and worked a treat.

One community college I worked at in the 90s had this one. Just so some teachers could get Netware access at home. None of them used it other than the person that implemented it.

We had a bunch of Shiva LanRover+'s that acted as a modem pool right up to the mid 2000's before VPNs were rolled out. I remember the management software worked on MacOS 9. That would have to be the laziest IBM rebrand.

You may want to evict that battery before it starts to leak! Or explode!
