DC power supplies and rectifiers for Cisco routers

My apologies for the simple question, but my attempts at Googling an answer weren't very productive. If anyone could point me in the right direction, that would be great.
I picked up a stack of 2600 series routers earlier this week. Mixed in them was a lone 7200 with a DC power supply marked as "48V/60V 13A/8A" with a 3-prong connector.
Also included with the stack was as a 120V AC to 48V DC rectifier marked "Argus RSM 48/7.5-15". It has two pairs of ports marked as + and -.
Am I correct in assuming that, as long as both units are functional, all that I'm missing is some sort of cable to connect the two? Between the two units, the only external power cord is an AC cord for the rectifier.

You've got a 280W 48V DC PSU. It requires 48V at 13A minimum. You can buy a regular AC module to replace it.I picked up a stack of 2600 series routers earlier this week. Mixed in them was a lone 7200 with a DC power supply marked as "48V/60V 13A/8A" with a 3-prong connector.
Is it a single module or dual? The datasheet for it shows that each module can supply 7.5A and you'd need more than 1 to power the 7200.Also included with the stack was as a 120V AC to 48V DC rectifier marked "Argus RSM 48/7.5-15". It has two pairs of ports marked as + and -.
Assuming that the power supply is actually a dual module cabinet then yes, you'd just need to wire them together. Do it properly though since 48V @ 13A isn't forgiving.Am I correct in assuming that, as long as both units are functional, all that I'm missing is some sort of cable to connect the two?

Just remember to wire it properly including earth and double check it before powering it up. A 48V DC @ 13A PSU can also work very well as a spot welder or fire starter :PIt is dual module cabinet. Thanks!
7200 AC PSUs aren't that expensive if you want to replace it. -

I would concur with Tiersten, just replace the DC powersupply with an AC one that will go in the 7200.The only easy day was yesterday!
