Thought I'd ask here one more time before searching eBay and stuff. To improve our evolving museum network, we can use the following: - Fanless rack-mount switch. Martin recommended the Juniper EX2200 or a fanless version of the Cisco 3010. He said the Cisco 2960 series also has fanless versions, but they sacrifice PoE which we need for security cameras. We could get by with 12 ports but 24 would be ideal - Rack-mountable UPS with good batteries. I don't have exact figures for the required specs. Stuff we'd be running: a couple of PC-like machines, small LCD monitor, small analog PBX, and no more than two network switches. The rack's other contacts do not need emergency power (stereo, minifridge .... well maybe I should reconsider about the minifridge ... in an emergency we might want a cold drink!) - Rack-mountable keyboard/mouse tray. - A bunch of the proper nuts/bolts to mount 4 or 5 components. - Unrelated: we could also use two chairs and one stool. We have some but they're old, breaking down, and don't match our decor. I would like to get nice ones that are typical black/chrome office designs. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan@vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
Evan, On the off chance any of the VCF has access: * Juniper EX2200-C, not the base EX2200. * Cisco 2960X or 2960XR There is a 24 port fanless / PoE versions of both. Try and grab the version model with SFP slots for 10GB uplinks * It's the industrial Cisco 3010 that can't be fanless and PoE Martin On 11/3/2017 11:11 PM, Evan Koblentz via vcf-midatlantic wrote:

Any simple retail 8 port switch would do, if fan-less is a requirement. A commercial/business switch would have a fan. On Sat, Nov 4, 2017 at 11:30 AM, Martin A Flynn via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

The ones I listed, per Martin, are fanless. We need more than 8 ports. Setting up everything in our rack rather than having consumer gear on shelves -- by design -- so that we're evoking a professional image to museum visitors, giving ourselves room to grow, etc. I like the sound of data center fans :) but others have told me they don't.

If you have a switch you really like but it doesn't have PoE, I can highly recommend one of these: https://www.amazon.com/WS-POE-8-48v60w-Passive-Ethernet-Injector-Cameras/dp/... I unfortunately don't have any to donate, but I'll vouch for them working nicely with 802.11af cameras. You shouldn't need more than 100 Mbps for IP cameras (truthfully, they seldom even saturate 10 Mbps); these work great with 100 Mbps switches. I have some spare rack mount 100 Mbps switches (including at least one fanless one, and non-fanless ones with slots for gigabit uplink) that I can bring to Festivus. If you're looking for a GREAT cheap fanless 100 Mbps switch with built-in gigabit uplink ports (semi-managed, even, in case you want to set up VLANs), I highly recommend the Netgear FS750T2, which can be found on eBay for pretty good prices. Note that these are EOL and probably have some security vulnerabilities, so you wouldn't want to expose them to the outside world (and might want to be choosy about who you expose them to at all). - Dave

It's a pass-thru that injects the PoE power on the unused pairs (100Base-TX only uses two pairs, the power uses the other two). Just put the box after the switch, put the cameras on the other side. 802.3af (the 100 Mbps standard) is considerably simpler than the gigabit version, which has complex autonegotiation requirements and the like.

I'll send you some details offline, probably tomorrow when I've had a chance to have a look. - Dave
You have to watch with no-name PoE injectors, most of them are not 802.3af compliant and will often either not work with 802.3af stuff or can actually damage it. Have someone confirm compatibility before purchasing. I'll have to see what I have w.r.t. available switches, if you have to buy something Allied Telesis makes some excellent basic managed PoE switches. I believe their smaller offerings are fanless. You will be hard-pressed to find a 24-port switch with PoE and no fans, it's just too much heat in 1U to cool without forced air.

This is true. I only have anecdotal evidence that it works well with my small sample of cheap Chinese PoE cameras which have generic 802.3af splitters built into the cable. YMMV. - Dave

Thanks for explaining, Jon. We could do with a 12-port switch. Eight ports would work * for now * but we need some room to grow. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan@vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
