how to install HPE B-series 32Gb SFP28 Extended Long Wave 25km 1-pack Secure Transceiver
- Power down (or ensure a safe hot-swap environment) for the device slot where the transceiver will be installed, or follow your vendor’s hot-swapping guidelines.
- Insert the SFP28 transceiver firmly into the available SFP28 slot until it seats with a secure click, ensuring the module is oriented correctly and the connector faces the motherboard or switch backplane.
- Connect the appropriate single-mode optical fiber cable to the LC duplex connectors. Ensure the fiber is clean and properly terminated to maintain low insertion loss.
- Power on the device or allow it to come online if hot-swapped. Verify the transceiver is detected by the switch/router via the management interface or CLI.
- Check link status, diagnostics, and LED indicators. If available, enable Digital Diagnostics Monitoring (DDM) to monitor optical power, temperature, and signal integrity. Confirm the 32Gbps link is established and the distance parameters align with the planned topology.
- Perform basic validation by running throughput tests and ensuring compatibility with the connected devices. If issues arise, verify fiber polarity, connector cleanliness, and that the correct wavelength and mode are being used for the fiber path.

Good milk frother, drink mixer
Color: Silver
I use this every day to mix my morning protein drink. Love that it's rechargeable. And it doesn't take long to recharge. Be advised that it has 3 speeds, so when you think you're turning it off, it's actually going faster and can splatter your drink. I've learned to mix on 2, then quickly push button to 3 and then off. The speeds aren't that much different, imo, so could have one speed "on', and then 'off'.

Do not buy
Color: Silver
The worst frother i've ever used. You can't even turn it off without having to go through all the different modes, meaning you will get absolutely splashed and have to clean all the little droplets of whatever you were frothing. The power is weak. The battery did last a long time, I'll give them that. 3 months ON THE DAY the frother stopped working. A very loud noise and decreased power made it unusable. I sent them an email with NO response.

Mixes drinks well and holds a charge
Color: Silver
I bought this frother to replace a weaker frother I had been using for months. I make iced lattes with instant espresso powder, water, and milk, and this frother does a great job at mixing the powder into the water/milk. It also leaves a nice 1" or so of milk froth on the top. I love that it can be charged with a USB-C cable and doesn't require batteries like many frothers do. It's very powerful for the size.

Putting my $.02 into the mix
Size: Basic Frother, Color: Black
My old, lame hand mixer finally gave up the ghost. I ordered one of those “stick blenders” but it was waaaay too powerful for my purposes. (I don’t need it to dice/chop/pulverize fruits or veggies - if you need that, this mixer isn’t for you.) I needed something in between. I kept coming back to the “milk frothers,” but I had my doubts that one of those could mix up my morning shake. I tried a frother some years ago, and it wasn’t designed for blending ingredients, just for frothing liquids. Still, I had an idea (like some of you might) that what I needed was not a true stick mixer, nor a true milk frother. Something in between. I needed a “frother on steroids.”
I settled on this one-the YUSWKO YW-218. It had the regular frothing head, but also two other heads. One looks like a mini bread hook; the other like a mini whisk.
I plugged it into charge and it did take the stated time to come to a full charge. (Like any kid with a new toy, I tried turning it on before charging, but the low state of charge resulted in the high-medium-low settings not behaving correctly.)
For my first few forays into blending, I tried the mini bread hook thingee. It worked OK, but not as well nor as quickly as I wanted. I then shifted to the mini whisk thingee. I didn’t really prepare well. I combined my milk-protein powder-carnation breakfast-malt flavoring-imitation (yeah, I know, it probably causes cancer, but only in California) vanilla flavoring concoction into my normal medium-sized concession cup (you know, the smaller ones you get at high school basketball games), lowered the whisk head into the goop, and turned it to “low.” In a second, I was wearing my shake. But the power capacity was more than enough to do what I was needing.
Anyway, since that first attempt with the whisk head, I’ve gotten the routine down. And it is EXACTLY what I needed. (I’ll try to attach a video to show you.). Clean up is simple. You can do it with soapy water and a brush or rag, but I just run the thing in clear water and ensure I get all the sticky stuff off. I tried the soapy water, but I got a LOT of suds.
A few pointers. First, charge it up all the way before using it. I haven’t had to recharge for two weeks now. You’ll use a regular, small phone-charging brick. (Two words of CAUTION. I found that the included, cheap charging cord did not work. It got really hot, like there was an electrical short in it. So I found one of my own. Also, DO NOT USE the larger charging blocks like the ones from Ap*le. I tried and it was too much.) Second, I assumed that the low speed would be the less aggressive and thus the less “throw-stuff-out-of-the-cup” setting. But that hasn’t proven true for me. I’ve found that the medium setting makes my ingredients behave better (less throw-out and quicker blending). Experiment with different speeds, even though it may not make immediate sense. Third, practice with plain water first (I’ve already told you how I know this). That’ll give you a “feel” for what this frother will do. Fourth, practice with different sized cups. I’ve since changed to the taller concession cups, as they prevent throw-out. Fifth, start practicing with your cups down in a sink. Less mess to clean up and no need to change clothes before you head out to work or school (I’m a teacher). Finally, familiarize yourself with the way the three buttons work. My previous mixer required me to keep the button depressed to blend. If I let up on the button, the unit would stop. Not so with this one. A light press to start, let go, then a light press to stop. Don’t keep mashing the button.
Final thoughts: this frother is just what I needed. If your experience sounds like mine, I think this one’ll give you good service.
