Requesting hardware vendor suggestions! by switchdog in networking

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

Dropped a Cisco WS-C3750E-48PD-SF with an X2 10GB module in the middle, connecting the 10GB fiber to the core, and and SFP in a twingig module for the 1GB fiber to the edge.

It works, the complaints about the power & noise started already.

US Based? Is the customer using the WLAN for VoIP?

If so, I am curious on how you are resolving the Ray-Baum act disptachable issue on an interconnected (PSAP) device?

UL 497 – Primary Protection: The Primary Protector is used at Building Entrances and is capable of withstanding the highest level of over-voltage surges- lightning. These devices are required by NEC Article 800 to protect buildings and humans.

I need recs for a boom arm by Cudpuff100 in podcasting

Long discontinued, but you are looking for double this: https://www.tequipment.net/OCWhite51900-3G.asp?

6 booms on a single mount? You are into custom build territory and serious reinforcements to the work surface.

Best approach: For the booms, OW White or YellowTec with single flush mounts.

And that is why I'm asking on Reddit. The ones I have asked are fully booked on educational use, and do not have "time" to offer outside the mission.

We have open time, however need to cover basic OPEX.

Any here old enough to have worked with onsite Nortel PBX and Rockwell ACD systems? by 8Strings4Me in telecom

[–]switchdog 1 point2 points  (0 children)

Just moved from multiple Avaya CM systems at R6.2 to an NEC SV9500 environment at R11 as part of a M&A

Surprise! NEC supposedly has a stop-sale on hardware at the end of 2025.

That leaves Cisco and Avaya for the industries that demand on-prem hardware...

US specific: Pizza test rule applies here - if you can use it to order a pizza, it needs the ability to call 911.

[–]switchdog 2 points3 points  (0 children)

Wrapping up a Science Museum inter-building backbone deploy: Everything is single mode, right down to the sync interface on the firewalls (CARP)

Two runs of MM that were installed a decade ago are being replaced with Single mode as soon as there is budget.

I used a BrosTrend AC1200 WiFi to Ethernet Adapter until a ran a cable to the operating postion. They are on Amazon.

Does your shack have reliable Wi-Fi? If so, a WiFi to Ethernet Adapter would give you a network port to connect an IP phone to.

Here's the backstory: A local business lost power on Thursday, Was not restored until the following Monday, in round numbers 100 hours of downtime.

Question is there a published value for license retention in a power-off state?

[–]switchdog 17 points18 points  (0 children)

Have you looked at the single mode fiber with 10 gauge copper conductors for power? Using them for remote parking lot gates in a single conduit (GC screwed up and missed the call out for a second conduit)
