The Xircom PE3 (Pocket Ethernet Adapter III) needed power either from
a PS/2 port or an AC adapter.
Phantom Power Cable
The Phantom Power Cable supplied with the Pocket Ethernet Adapter III
allows you to power all Adapter models (except PE3-10BX) directly from
a PS/2-style C6-pin mini-DIN) mouse port on your computer. The cable
includes a pass-through connector that allows a mouse to be plugged in
on top of the Phantom Power Cable connection.
Wall-Mount AC Power Adapter
AC power adapter specifications are listed below for the US.A. and Canada
Input Voltage: 120 VAC / 60 Hz

Correction to my posting of 2/10/2025
There was a company called Xircom that made parallel port modems. These
were full modems that were small enough that they plugged into a laptop
serial <parallel> port, and got their power from the laptop via the
external mouse/keyboard port. They had a feed-though connector so you
could still connect and external mouse/keyboard if you wanted. ...
So which is it? My memory of the time was they were RS-233 devices that got
their power from the keyboard port via a pass through cable. If they were
parallel port, the PP provides enough power...
Xircom also had parallel port ethernet products...
