That's unusual. IBM never had any 110v equipment in the computer room.
We didn't even bring a neutral to the distribution panels. Even the
smallest stuff was 240 or 208v. Later they did start putting in 120v
plugs for terminals but a lot of places just plugged them into the
convenience outlets in the frames. (transformer fed)

Some parts of IBM made stuff that didn't live in computer rooms.
