DC power supplies and rectifiers for Cisco routers

UnixGeek

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.

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.

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.
