Nice switch! Any idea how you’ll be setting it up? What does your network topology roughly look like at the moment? (I hope you didn’t mind me splitting this into a new thread, it definitely deserves it.)

I see! Any progress to report?

Looks good! I see you got GBICs, but rather for fiber they appear to be adapters to copper for UTP, correct?

Sorry for LQ quality, i’ve just loaned my cam to a friend. Last photo shows some modifications: grean heatsinks installed on networks chips; redudant PSU got removed; all 5 stock fans removed (including that one in remaining PSU); finally i installed just two cheap silent fans. Works like a charm.

That’s good to hear. I’ve also been modifying hardware in the meantime, like (for example) I have fixed and replaced the NVR/TOY battery in my DEC Multia/UDB.

P.S.: Sorry, Marco, for not being on Skype :(.

No problem, I was merely curious what was going on. It has been, what, months? Good to see you’re alive and well.

There’s also fiber over copper, but it’s usually non-UTP. At least, as far as FC (for storage) goes. I’m not sure what exists for fiber ethernet. The Origin3200 I had used DB9-like FC-AL copper connectors.

And actually, i have only one 1000T module, more like for testing purpose. Another one i got as bonus, and it’s limited to other kind of firm gear, so it’s not working in Summits.

I see.

That’s nice :slight_smile:

Believe it or not, but NetBSD would whine if the NVR/TOY (Non-Volatile Random Access Memory & Time-of-Year) chip couldn’t hold an accurate system time. A rather strange requirement, coming from NetBSD. One would think that NetBSD, of all operating systems with all the legacy platforms, would be a bit more ‘tolerant’ in that regard (especially as there’s NTP, for instance, to overcome these types of non-issues).

I seen similar problem when used OpenBSD/macppc on Apple PowerBook laptop without battery. However, besides the textual warning, it didn’t gave me any troubles.
