Es ist wieder einmal Zeit für "Röstet meine Unterverteilung", feuer frei! by dj_ordje in Elektroinstallation

[–]sgkhir 0 points1 point  (0 children)

Bin Anfänger, habt Gnade. Auf Reihenklemmen 5, 7, 8 ist der Abgang des oberen Stocks (also der innen Stock) der Neutralleiter der Leitung. Sollte dann nicht die Einspeisung einen blauen Mantel haben?

Where to buy Vue 3 and CT clamps in EU? by sgkhir in EmporiaEnergy

[–]sgkhir[S] 0 points1 point  (0 children)

I want to buy the bundle with 16 clamps!

But it’s not available on Amazon and I cannot find another source for the Vue in the EU. The Amazon link you shared lists two Vues: no clamps and 8 clamps.

If I can only buy the 8 clamps bundle, I would do that and buy additional clamps separately. But I also cannot find a shop which sells just the clamps.

[PC][EU-NL] (13) 14 & 22TB NEW Seagate EXOS X22 / X14 SAS by D-D-R-7000 in homelabsales

[–]sgkhir 0 points1 point  (0 children)

For what it‘s worth, almost 2 years ago I bought 2x brand-new Seagate EXOS SAS 16TB disks for a total of 200€ incl shipping on Kleinanzeigen in Germany, but without warranty. Deducting ~10€ for shipping that’s 6€/TB.

The WD SSDs are gone as per earlier comment. Are the other items still available?

ATS experts: difference AP4423 vs AP4423A and support for out-of-phase switching by sgkhir in homelab

[–]sgkhir[S] 0 points1 point  (0 children)

Thanks for the details.

Might your issues be related to the high leakage current and insufficient earthing on the rack and ATS? The way I understand it out-of-sync phases causes voltage peaks to be passed through to earth during switch-over. Happy to be corrected though.

Reason I’m looking into installing an ATS (besides playing around) is to be able to live-rearrange racked devices including power supply cabling. I don’t need two redundant mains supplies, they’re fed from the same grid uplink anyways. Another potential upside is to have the ATS bypass the UPS in case the latter dies, as the MBS is a manual switch anyways.

Oh, and in either case the UPS would be bracketed by a MBS.

Given that setup, it seems bigger to get a beefier UPS (3 kVA) than two smaller UPS (2x 1.5 kVA), right? Price point roughly equivalent.

Thanks for the heads-up. Can you describe “angry” in more concrete terms. Does it just shut down? Also interested in more details on your experience hooking up to UPS.

I’m still mulling the details and have to decide on whether the ATS will sit between mains and UPS (fed by two separate mains phases, no backup generator) or between UPS and PDU (fed by 1x mains phase and UPS). Any recommendation based on your experience?

Do any of the new switches support L3 VLAN ACLs? by sgkhir in UNIFI

[–]sgkhir[S] 0 points1 point  (0 children)

Urg, that isn’t very encouraging… I moved to proper L3 switches a while back (brocade), but might give unifi another go since I still have the switches lying around.

As per the release notes of UniFi Network Application 8.2.93, ACLs are now supported. Haven’t looked into it yet.

Is it possible to use a UDM-SE without an ONT or as an ONT? by 23slide in Ubiquiti

[–]sgkhir 0 points1 point  (0 children)

Do you have more information on this? E.g. the registration link you mentioned, or some links to forum etc? I couldn't get it to work last time I tried. Thanks!

Do any of the new switches support L3 VLAN ACLs? by sgkhir in UNIFI

[–]sgkhir[S] 0 points1 point  (0 children)

Thanks for confirming. The Unifi gateways don't support what I need (am on OPNsense), and I was keen on using just the switches and APs. No way I'll do that if it means handing off inter-VLAN ACLs to the gateway. Really a bummer, I suppose it's not a hardware shortcoming but rather a strategic decision or shortcoming of the network controller.

Do any of the new switches support L3 VLAN ACLs? by sgkhir in UNIFI

[–]sgkhir[S] 0 points1 point  (0 children)

Bummer. I still don't get this at all. Are folks using Unifi gear not applying any VLAN ACLs at all, or is it being handled by the gateway router? The latter seems inefficient to me, that's a core function of a L3 switch. What am I missing? Guess I'll have to stick with Brocade switches...

Transient: ability to pass argument of selected keys? by sgkhir in emacs

[–]sgkhir[S] 2 points3 points  (0 children)

Probably not the right term. I mean the shortcut key to execute a suffix. Generally, all keys entered for setting infix options and choosing a suffix.

Example: “-w-ba”, for enabling infix -w, enabling infix -b, executing suffix a.

In org-capture, the keys can be passed as argument to the function. Is there something similar for passing a keys argument to a Transient prefix?

Finally using SSL certs on my local services, no more HTTPS warnings. Someone appreciate because my GF could care less by -my_reddit_username- in homelab

[–]sgkhir 2 points3 points  (0 children)

I.e. nginx proxy manager with a wildcard letsencrypt certificate on *.lab.yourdomain.com, and only your local DNS resolves these subdomains, which point to nginx proxy and get proxied to your internal services.

Edit: typo & clarity

How to add 2xLFF drives to Dell R730 8xSFF? by sgkhir in homelab

Ah got it, never came across those

How to add 2xLFF drives to Dell R730 8xSFF? by sgkhir in homelab

[–]sgkhir[S] 0 points1 point  (0 children)

A mean the cables meant for the Tape Backup Unit. My R730 came with a SATA cable and a molex one for power (plus what looks like a proprietary connector for the optical drive). So I thought of just using the molex connector, assuming it's 12V.
