but they can still attack the modem. wasn't there a firmware exploit a while ago ??

324112 2005-05-20 23:24:00 Just to add; the plug pack voltage is only really meaningful if measured when it is plugged in to the modem and is under load. Terry Porritt (14)
324113 2005-05-21 12:42:00 Thanks Terry for the reminder - quite right - the voltage at the circuit board, while running, was 10.1V AC while the mains was 234V AC at the time. KiwiGPS (7273)
324114 2005-05-21 12:43:00 My dsl 302g modem stays very warm, pretty close to hot. I always shut down the computer when not using it.
I am picking it is using a lot of electricity.
I think Telecom might be up for big damages soon as I am sure they will start catcing fire.
I cant belive they make something like this which draws a lot of power with no on off switch.

324115 2005-05-22 00:35:00 Modems don't use a lot of power Ted, check the wattage rating on the case or power pack, it will probably be 15 watts or less. If a power pack is used, that rating may be a lot more than the amount actually consumed by the device.

Localised heat can be generated by 2-3 watts of energy, usually from the internal power regulator, and in a small enclosure it will heat quite nicely! There is rarely anything to worry about.

324116 2005-05-27 07:59:00 I fitted the temperature sensor of a digital "indoor / outdoor" thermometer in the case at the power end and noted 43 degrees C with an ambient of 21. The pdf data sheet says the operating temp is 0 to 40 while the Spec sheet says 0-50. Whatever it is, higher temps cause earlier electronics failures so I opened up the restricted vent slots by removing the thin dividing bars. I guess they are designed to keep staples & the like out of the works. Temp now stays around 36 now.

Current drawn by the plug pack is 33mA when in use, 31mA when not in use. That's around 7.5 watts - or $10 to 12 per year if never turned off. And that's only 1 plug pack of the collection behind my desk!
