how to install Lenovo S4520

Installing the Lenovo S4520 240 GB Read Intensive SATA SSD is straightforward in servers and workstations that support 3.5-inch internal SATA drives. Follow these best-practice steps to ensure a clean, safe installation and optimal performance:

  • Prepare the system: Power down the host, unplug from power, and ground yourself to avoid static discharge. If you are replacing an existing drive, remove the old drive from its tray or carrier with care.
  • Remove the drive tray: If your server uses a hot-swappable or tool-less tray, release the latch or remove the screws to free the drive bay compatible with a 3.5-inch module.
  • Insert the S4520: Align the drive with the tray’s mounting holes and secure it using the appropriate screws. Ensure the drive sits firmly in the tray to prevent movement during operation.
  • Connect data and power: Attach the SATA data cable to the motherboard or storage controller and connect the SATA power cable to the drive. Verify that all connections are secure and routed to minimize airflow obstruction.
  • Mount and power on: Slide the tray back into the drive bay, secure the tray with latches or screws, and power on the system. Enter the BIOS or the storage controller’s management interface to recognize the new SSD.
  • Initialize and format: Use your operating system’s disk management tools or the storage controller’s utility to initialize the SSD, create partitions, and format with your preferred file system. For best performance, align partitions to the drive’s erase blocks and enable any recommended optimization settings in your environment.

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days

Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.

My puppy LOVEs this ball
Color: Glow in the dark I, Size: Medium
I saw someone recommend this ball in a facebook group. I ordered the first one and it is now sitting somewhere under my deck and I can't find it. My dog loved it so much I had to order a second one. I think the fact there are so many tabs it makes it easy for him to grab it and run so very functional. He doesn't always like to share. The glow in the dark ability I would rate that good at all. The rest of the ball is good quality and holds up well against my aggressive chewer. Its easy to throw or kick. It isn't super hard but is holds it shape well. My dog is about 8 months old and is a mini goldendoodle. I think he was about 18lbs in the video. Perfect size for him. I would definitely recommend, I think your dog would love it!

Corgi goes crazy for this ball
Six months now, still five stars. It is still easily our Corgi’s favorite ball & she still enjoys it all kinds of ways. Rather than tiring of it she likes it even more. She really likes the tabs that make it so easy to grab & hold onto. The ball is all roughed up & torn up still but held up well & has not had to be pumped back up at all. As others noted a small manual ball pump, about 10” with i think 3 different attachments, is included with each order. The glow in the dark stuff is apparently a coating of some kind which has been totally rubbed off. I used an art pen with glow liquid to trace the pattern on the ball for a glow refresh, we’ll see how long that lasts. It is hard to find toys she likes that much, i highly recommend! Our Welsh Corgi goes nuts for this slightly smaller size soccer ball. She had a full-sized ball that we left slightly deflated so she could run with it. This one is even better than i ever would’ve guessed it would be! The tabs, including a longer tab useful as a handle for humans, make it easy for her to grab it or run all over playing keep away with it. Not interested in herding this ball when she can run all over the yard with it or carry it everywhere with her. She’s a super strong chewer in spite of being small so it is extra durable by our tough standards & it appears that it will last at least a year im guessing. Quality materials & craftsmanship. It’s held up over a month - roughed up but not excessively. The glow in the dark feature is not as bright as the photos - don’t buy it just for that - but it glows some given enough daytime sun, and a dark night so the glow can show. Only the top side of the ball that’s facing up can absorb the sunlight at a time so it’s unlikely that the entire ball could get the amount of sunlight needed to glow brightly all at once. All and all this is the best, most well used toy purchased for her during her one year with us, well worth the $$ and recommend buying it if your pet enjoys balls, keep away, herding, and/or fetch, anything like that. She also likes to hide it from me, just the right size for that.

Pawsome product!
Color: Glow in the dark I, Size: Medium
Pawsome for our doggos! We have bought 5 because the puppy chewed the tags off. Our dogs are border / aussie mix and love the challenge of these balls. We named them "Wilson" because they treat them like their best friend.
