RE: Running a DC powered Catalyst 1900 ???

[Ray Mosely]

Somebody else said that it was 48 volts. That's the line voltage on a telephone line, and as we know, a telephone line does not carry a lot of amps, so almost any 48 volt source would be enough. Two marine batteries, or four garden tractor batteries would carry it for many days before needing re-charging. You could hook up 8 of those big square 6 volt batteries. 5 or 6 9-volt batteries would probably run it, but they would poop out pretty quickly.   The best bet is to find a telco supply, like Marlin P. Jones, and order a 48 volt power supply. http:/www.mpja.com Their catalog lists 48 volt supplies starting at $4.00 and up.   Good luck, Ray M, CCNA     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Circusnuts Sent: Thursday, July 06, 2000 8:05 PM To: [EMAIL PROTECTED] Subject: Running a DC powered Catalyst 1900 ??? I think I've goofed.  I bought a Catalyst switch & did not read the ad correctly.  I have a DC running device.  How can I use this ???    Any advice (other than jumper cables from my car :-)   Thanks !!!
