network failure; sd216 switch runs hot, blinks incessantly

Hello. I have been using the Linksys sd216 switch in a small network for about two years.

The switch has always been rather hot to the touch when it is activated / switched on.

Today, network connectivity has failed, and I have traced the problem to the sd216 switch, which apparently has failed.

I am trying to get more information on the sd216 switch, but the PDF datasheet on linksys.com for the sd2126 is corrupted.

My question for this forum: when the row of green lights along the front of the sd216 switch blink quickly and incessantly, does this indicate switch failure? (I assume: it ain't good news.) My real question: do the blinking lights indicate a particular problem for which there is a particular remedy?

I have turned the switch on and off, and let it cool down. Connectivity is still negative.

I am off to buy a new switch for my network. But, if anyone has any information about the sd216 switch, including error messages or useful news about the pattern of blinking lights, I am most grateful for your input.

Kind regards,

Eric Bourland

looks like the 205, 208, & 216 are part of the same product line.  Doesn't look like it flashes anything else than green..

That's useful to learn that the 216 is part of a larger product line. I went ahead and replaced the Switch and the new switch works fine ... and runs cooler. Thanks for your help.

Thanks for the points.  Kinda surprise (in one sense and not in another) that a fan was not part of the 216 design, if they realized the potential heat output.
