Hi Sam,

Unfortunately, power supply is not a replaceable unit on WS-C3750G-12S-SD switch. It comes bundled with the part ID "WS-C3750G-12S-SD". Please see below:

Hi,

WS-C3750G-12S-SD WILL come with an integrated DC power supply. However, just the power supply cannot be ordered separately.

Cheers,

Such power adapter will not work. The power supply is inside the switch chassis and in case the power supply goes bad, you will have to replace the complete switch.

thanks

Hi

You must connect the Catalyst 3750G-12S-SD switch only to a DC-input power source that has an input supply voltage from -36 to -72 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged.

So how do you go about  to get that ?

well it all comes down to if this is a switch for you private or a switch for your company.

if it is a switch for your company then you go and tell the guy in charge of the electricity in the area that you want to place the switch that you want a connection for the switch and give him the specifications and let them fix it.

IF it is a switch for you, fx bought on ebay or refurbished or so on, you buy a dc powersupply for lab use and measure it up to the correct specifications and connect it to the switch. check the link above on how to connect it. Basically anything that delivers the proper dc current to the switch. even batteries will actually work if you know how to connect them right.

Good luck
