Hi,

You'll most likely be appalled at the ridiculous simplicity of this problem,
but I'm entirely new to this, so please forgive me

I need to replace an AC/DC converter within a switch.
The new converter has 5 connectors:
AC/L AC/N Ground VDC5+ VDC5-

1. Question:
Am I to connect the ground of the converter to the same ground
which is connected to the switch's casing?

2. Question:
The switch has 3 cables running to the converter.
Red, black and white.

I guess red should be VDC5+, white VDC5- and black is the ground.

Is it ok to attach the black cable to the same ground as the converter?


Thanks for your help.

 

Could you supply some additional information. There are several interpretations of AC/DC converter. And one "within a switch" leaves me clueless.

 

Sorry, I meant a power supply within a KVM switch.

To be precise

I have to install this:

Within a model similar to this:

The cable within looks a bit like this, but with a different connector:

Thanks in advance!

 

Question 1 Attach the ground of the converter to the wire that is attached to the case (green) on the switch.
Question 2 as a rule for DC red would be positive and black negative (North America) but that is not always the case. I would not connect power without knowing the polarity of the power plug. Also i would not advise hooking up the DC side to ground unless the third wire is designated as chassis ground.

 

Thank you. That gets me a step further.

I guess I have no way of finding out the polarity,
because there are no markings on the circuit boards
themselves, but the switch is considered 'damgaged
beyond repair' anyway, so I guess I'll just give it a try.

If it is not advisable to directly connect the black/DC-ground
to the AC-ground, then is there any another simple way to
wire it to something in order to make it work?

 

One way find the polarity is to look at the circuit board to see if there is a filtering capacitor accross the power input, then follow the traces back to the connector.
