First into the Garbage Can when the Revolution comes

netgear_gs-608This is a Netgear GS-608 8-port gigabit Ethernet switch, which replaced the D-Link DGS-1008D with the overheating problem.  Mostly plastic construction with this cool chrome band running around the edge.  Looks spiffy, like an iPod’s larger brother.  Mounted horizontally it gets very hot very rapidly.  Mounted vertically it is able to dissipate some heat and doesn’t appear to get as hot.

Ordered: 10 April 2007
Arrived: 13 April 2007
Failed: 25 April 2007

It was a great switch for exactly two weeks until it, too, overheated and failed.  it is being RMA’ed to the reseller and replaced with an identical unit.  Even as a backup, I know any Netgear replacement will only operate for two weeks before our network traffic fries it.  In fact I shouldn’t have RMA’ed it — its first, best destiny is to be smashed with a mallet.  Or have its identical replacement smashed with a mallet.  Either way,  a GS-608 in my possession should be smashed with a mallet.  Unfortunately, Wanda vetoed this plan or any meeting of switches and mallets.   So the replacement for the RMA’ed unit is going to be cast into the Storage Closet of Weeping and Gnashing of Teeth, to await the day when the heavens fall and a Netgear is entrusted — as a matter of last resort — with the Reliable Delivery of IP Packets.

linksys_sd2008 This is a Linksys SD2008, hardware rev 2.1.   As you can see it is presently installed with all eight ports occupied (seven in fulltime 24/7 use).  All-metal casing (except for black plastic faceplate) which gets fairly hot but, being metal, is able to dissipate the heat readily like a giant heat sink.  What you can’t see is that this is (I think) a fan-cooled unit.  The fan is noiseless, the only giveaway being a slight vibration of the casing, undetectable unless you have a hand resting on it.

The rev 1.0 hardware (with grey faceplate) of this same model also had an internal fan but was, according to many reviewers, incredibly noisy.  The 2.1 rev has mainly positive reviews and some people think it is fanless, but if so, what the heck is creating the case vibrations?  There’s a moving part in there somewhere, and my bet is on a fan.  I breathe a bit easier knowing that there’s some active cooling at work — something above and beyond clever case design.

This unit has only been operating for three days so I can’t give it a complete endorsement, but if it survives for more than five or six months you will surely read about it here.  If I were a betting man I’d wager on this guy to survive into the long haul.

UPDATE 272226Z JUNE 2008: The DGS-1008 was given to Dax and continued to function (normally) for about another half-year to a year.  It finally gave up the ghost  last month.  So to the guy Googling for “DGS 1008 overheat”, caveat emptor.  The SD2008 continues to truck along without error and it also runs cooler than any of its Linksys, D-Link or Netgear predecessors.  Oh, and it has no fan… that was just the two PCs in the chassis below making the slight vibration.
