3Com Officeconnect 16 Port Dual Speed Switch

[Peter K]

Hi

Looking for the PSU pinout.
PSU died some time ago, but the switch still worked.
No longer have the PSU, but have the cable.

The connector is 4 pin, with Red, Black, White, and Screen.
The label on the switch says 5vdc.

I ran it from a PC PSU some time ago fine (on 5v), but now I cannot remember
the
pinouts.

Ta

Peter
