Power Supple

[jjsm]

I have two Netgear power supply units and do not know which one belongs with my CM600 cable modem. One is Model AD2032F10, P/N 332-10751-01.  The other is Model 2ABB018F, P/N 332-10748-01.  Can anyone tell me which one belongs with the CM600?  Or does it not matter?

   If the connectors are the same size (inside and out), and the
polarity is the same, then either should work.  As you can see from the
C600 User Manual, or, I assume, from the C600 product label, 12VDC, 1.5A
is the required output rating.

> The other one indicates Input of 100-240V / 50-60Hz / 0.6A

   So, you could use one of them anyplace in the world, and the other
one only where the supply voltage is in the 100-120V range. Like, for
example in North America.

   Shouldn't.

   Not to me.  The C600 User Manual does say:

      Input: 110-120V, 47-60 Hz

so it's possible that the adapter with the more limited input voltage
range was supplied with the C600.

   Actual voltage and current ratings, which I'd expect to be printed on
the poweradapters, too, would be much more helpful.  Compare the ratings
printed on the adapters with the ratings printed on the devices.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual.  Read.  Look for the power
adapter ratings under "Technical Specifications".  Those should agree
with what's printed on the device label.

The label on the modem itself indicates 12V <--> 1.5A.

Both power supply units indicate Output at the same level:  12V <--> 1.5A.

The only apparent difference is that one indicated Input of 100-120V / 50-60Hz / 0.56A

The other one indicates Input of 100-240V / 50-60Hz / 0.6A

So, I guess my questions are (1) will either one damage the modem and (2) does it matter at all which one is used?
