I got 2 old 2900 series switches that was not being used by a company and I noticed that they had "kettle lead" power connecters the same as a PC so I connected the pc power leads to the switches and boom boom shake the room. seems I dont like the smell of fried circuitry in the morning.
Im guessing this was not a problem with the switches themselves?

If it was a DC powered switch then it wouldn't have an IEC connector. -
Optionstha_dub Member Posts: 262I'm gonna put my money behind the 110v switch theory. Lucky for us north americans using 110. We can connect 110 to a 220 usualyy without cooking it....

Optionsceltic_tiger Member Posts: 41 ■■□□□□□□□□Says near power socket
100-127/200-240V
2.0A1.0A 50-60HZ
there is a DC input which looks like the powerinput on the motheboard on a pc on the back also. -

No idea why it blew up. It shouldn't do... -
Optionsceltic_tiger Member Posts: 41 ■■□□□□□□□□hmm i see
I use the same leads for my pc's and they are running on them now. there was a loud bang all the lights lit up for a split second and a worrying smell also this tripped the switch taking the electricity out of the apartment. -

If only you had a picture, or video of this event -
Optionstiersten Member Posts: 4,505Not many theories left as to why it went bang.
1. Both are faulty.
2. Both have had PSU replaced with a 110V unit for some unknown reason.
3. Your apartment has a really odd electrical system.
4. You've angered the god of networking in some way.
None are particularly likely but I guess number 2 is the one that is most probable. Somebody has altered it in some bizarre way. -
Optionsceltic_tiger Member Posts: 41 ■■□□□□□□□□Im guessing they are both dead now. But just in case Is there an inexpensive way to try and see if they will work with the 110V power. just in case they were american switches. like an adapter or some such.

Optionsmikem2te Member Posts: 407It may be worth a look inside in an attempt to find out what went wrong.
Typically with mains powered equipment there is a risk of electric shock (I know that from experience). Electric charge can remain in devices for a good few hours so I always make sure the device has been physically unplugged for hours before taking apart.Blog : http://www.caerffili.co.uk/

Believe me, electricity isn't the best friend to you, I lit up once and had electricity in my body that was enough to feed a house, I did look like Mike's cat , wasn't the best experience, crash! Was it an old cable or has some issues? Did you shorten the power by inserting one of the prong way before the others? Did you check the power supply, for sure before you plug it, that it's properly installed and the connector is seated well in it's socket? Never hurry and power up any Cisco from eBay, or anybody else, that you don't know before checking it, one of my friends was suppose to get really bad shock because of a Cisco router that he bought off eBay and found out that the PSU had 2 naked (h*rny) wires that touches each other.
Bottom line, if ur lucky then it's only the PSU toasted, you can get it off ebay, but if it passed the PSU then kiss your switches goodbye.
