Re: IBM 9406-720 power cable

Hi Larry!
Thanks for the answer!

I've tried a few possibilities...

o I removed the cable (marked in blue) and plugged the power cord
into the power supply (marked in red)... when I did this, no
part of the system got any energy

o I removed the batteries and plugged the power cord into the
power supply ( marked in red ), when I did this, no part of the
system got any power

What I did not try

o I plugged a power cord into each power supply (marked in red)

I'm going to run a test today with a multimeter to see if energy is coming out of the power supply ...

You will need 200V 20A for that machine with a C19 type line cord.

The line cord goes into the bottom most connector in the right side (facing the rear) That is both a UPS and PDU for the server.

The batteries in there are VERY common units this link gives you a great picture of the correct battery type. (size, voltage, amperage & connector) You would need four.

Alternatively you could simply plug in two line cords, (same C19 type) into the two power supplies (where the jumper cords connect today.)

I would remove the vertical jumper at the center line in that case. That provides power from the UPS to preserve memory contents in a power outage. If the UPS isn't in use that isn't going to happen!

Hi!

I bought an IBM 9406-720 with #2061 processor, but, I am in doubt to the electrical connection of the computer....
For better explanation, see the images from the back of the computer

My computer has 2 fonts, one of 480w ( image 3 ), and the power supply for the batteries ( image 2 ), should there be a power cable for each power supply ?
The batteries are probably already dead ....
