how to install Black Box LBH120A-H-SC Ethernet Switch

Installing the LBH120A-H-SC is designed to be quick and straightforward, making it a practical choice for on-site deployments where time and simplicity matter. Start by identifying a stable location near the devices you want to connect, ensuring there is adequate ventilation to prevent overheating and enough space for cable routing. Prepare your Ethernet cables (Cat5e or better recommended) and keep a short set of spare cables for testing connections during the setup process.

  • Connect each device you want to add to the network to the four RJ-45 ports on the LBH120A-H-SC using standard Category 5e/6 Ethernet cables. Ensure all connections are snug and fully inserted to establish a solid link.
  • Power on the switch according to your site’s electrical setup. If an external power supply is used, verify the supply voltage and polarity match the unit’s requirements and confirm the power indicator LEDs illuminate as expected.
  • Check the link LEDs on each port to confirm active connections. A steady or blinking light typically indicates a healthy link, while no light suggests a connection issue or miswired cable. Swap cables or devices as needed to verify proper operation.
  • Test network communication by pinging connected devices or performing a simple data transfer test. Confirm that data is flowing between endpoints without unexpected delays, and monitor the switch for any unusual LED activity that could indicate a fault.
  • Secure the unit in place if mounted in a fixed location, and label cables to simplify future maintenance or expansion. Keep cables neatly organized to avoid strain on connectors and to reduce the risk of accidental disconnections.

Save some money by doing your own cabin filter change! (You won't notice a difference).
So, one day I was getting an oil change at the dealership, and the associate told me that cabin filter was pretty dirty, which I believed because of the places I take the car, and she said that they could change it while they were finishing up the rest of their inspection, since they already had it apart. I asked her "How much?", and then we both had a laugh when she said "$90." I told her I'd take care of it. It took two days for Amazon to get a replacement filter to me, twenty minutes to watch a You Tube video showing how to replace the cabin filter on my car (I watched it twice), and then about twenty-five minutes to replace the filter itself--I keep a messy glove compartment, so a good portion of the time was loading and unloading that nightmare. In the end, under $15 for the filter, maybe 45 minutes to watch and replace, and the cabin filter hasn't been this good since I first bought the car. This replacement version was as good as the OE filter, fit exactly the same, there's no difference in airflow that I can tell, and so far (6 months later), it seems to be holding up pretty well. We'll see what it is like after a year. I did get the oil changed about a week ago, and the technician didn't raise any alarms about the filter, so everything seems to be working. $90 for a new filter? You can do it yourself cheaper.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.
