[AFMUG] Ciena 3930 Power Question

Slim chance, but does anyone know if I can power a 3930 off of a +48VDC system? The spec sheet says: DC Input: -48, -36, +36, -24, +24 VDC (nominal) Does it seem odd that it can accept -/+36 and 24, but not 48? An AT&T tech installed a 3930 at one of our sites and wired it directly to our +48VD

Re: [AFMUG] Ciena 3930 Power Question

Yes I believe they are isolated inputs, I have ten+ 3930's running on +48v On Thu, Oct 22, 2020 at 6:51 AM Josh Baird wrote: > Slim chance, but does anyone know if I can power a 3930 off of a +48VDC > system? > > The spec sheet says: DC Input: -48, -36, +36, -24, +24 VDC (nominal) > > Does it

Re: [AFMUG] Ciena 3930 Power Question

A quick check with the multimeter shows the +/- terminals isolated from the ground. Markings on the supply say 20-60VDC. As long as you get polarity correct I believe they don’t care where the ground reference is. Mark > On Oct 22, 2020, at 9:50 AM, Josh Baird wrote: > > Slim chance, b

Re: [AFMUG] Ciena 3930 Power Question

Measure resistance between the ground terminal and the positive terminal and also between the ground terminal and the negative terminal.It should be very high - on the order of MegaOhms. It’s not an absolute test as there could be active circuit elements or diodes between the power and gr

[AFMUG] SIP trunk providers at IXes?

I thought this would be easier to find information, but apparently it's not... are there any SIP trunk providers that participate in peering at exchanges? All I've been able to find so far is Twilio Interconnect (after filling out a form). Most of what I can find just seems to be handwaving it

Well yes, mine, but also any that my customers may use independently of me. Also, like me, Seth runs an IX. We're always trying to find networks that would benefit from IXes. VoIP providers would be an obvious one, but many of them don't seem to know how to run networks. - Mike Hamme

Re: [AFMUG] SIP trunk providers at IXes?

We don't peer specifically. We choose data centers like INAP and Equinix that have lots of customers located in their centers and large peering fabrics built. I think of peering as more of a BGP thing, which I am more concerned about consistent low latency between my switch platform and my customer
