Thanks for the eBay pointer, parts are on order.Fiber is a good idea!
I have a v1 1810-24g at home and have been very happy with it. I never have to reboot it although we do sometimes have the power RCBs trip as we overload our 35A home power limit (wifes hair dryer / Iron usually tips the balance not the 42U rack of servers ). Mine did develop an issue, after around 5 years, but I called HP and the next business day a replacement (reconditioned) unit was delivered to my home. Cant really complain at that. The new version (1810-24G v2) has lower power requirements and a few other tweeks. These are the switches I sell the most of by far.Q: Does the ProCurve Switch 1810G series support Spanning Tree Protocols (STP)?
No, the ProCurve Switch 1810G Series does not support any of the Spanning Tree Protocols (802.1s, 802.1D, or 802.1w). However, BPDU packets are still passed.
I purchased several HP 1810 V2/V1 and 1800 the last years, because those 24 port switches are fanless. But lately I changed to Zyxel GS1910-24. The main reason was software features. HP´s 18XX series doesn´t offer very much. Just look at Zyxel´s comparison: http://www.zyxel.kr/support/matrix/gs1910-24hp.zipDoes the 1810 support STP? I have one for light work but I coulda swore it did not support STP and thus was only good at the edge. STP is important to use!
I believe the Finisar FTLX8571D3BCL 10GbE SFP+ transceivers work with the the HP 1800 series switches. These can be had for less then $40 on eBay (they also work with Mellanox Connect-X EN cards).Fiber is a good idea!
You do need to be careful when selecting the SFPs. HP "brand locks" their SFP interface so you need to get modules that will respond as if they are HP branded. You don't have to get actual HPs SFPs - they are expensive. There are grey-market parts that should do the trick. I don't think the IBM branded SFPs will work in the 1910.
Try these instead: HP Compaq 229204 001 1GB SFP Transceiver 212192 002 JDS Uniphase 52P6539 | eBay
We have a lot of talented individuals here.How can you guys find these things so cheap on ebay?
The HP 1800-24G and 1810-24G v2 switches do work with the Finisar FTLX8571D3BCL 10GbE SFP+ transceivers in their SFP ports. They also work with Intel's SFP+ Twinaxial cable (XDACBL1M).I believe the Finisar FTLX8571D3BCL 10GbE SFP+ transceivers work with the the HP 1800 series switches.

You could go 100' with Cat-5/6, but you are exposed to electrical/grounding issues and - depending on where you live - picking up surges from lightening. You are also of some risk of ground potential differences between the two buildings - probably not too much risk if the barn is on the same electric service as the house but there is some.

I'll check it out again between my HP 1800-24G and 1810-24G V2 when I get home to be sure.
When you say these work with 10g SPF are u saying they will nogotiate a 10G link between it and a Mellenox EN card or that it will negotiate a 1G link? I have had this switch 1810-24 v2 for about 2 years so I'd be very surprised if it could handle any 10g since its not in the specs.The HP 1800-24G and 1810-24G v2 switches do work with the Finisar FTLX8571D3BCL 10GbE SFP+ transceivers in their SFP ports.

1g switching only, the 1810 series shares the SFP with RJ45 ports anyways. A link between two full transceivers might(?) run at 10g but the link between transceiver and the 1810 backplane isn't going to give it that so its moot.When you say these work with 10g SPF are u saying they will nogotiate a 10G link between it and a Mellenox EN card or that it will negotiate a 1G link?
