How to Install Lenovo QSFP+ 40GBase-eSR4 Transceiver

Installing the Lenovo QSFP+ 40GBase-eSR4 transceiver is a straightforward process designed to minimize downtime and ensure a reliable link. Before you begin, follow standard anti-static precautions and verify that your IBM system and network devices expose QSFP+ ports compatible with 40GBASE-eSR4 optics. While this guide outlines typical steps, always refer to your hardware vendor’s maintenance manuals for model-specific instructions and safety guidelines.

  • Power down or prepare for a hot-swap, if your equipment supports hot-swapping of QSFP+ modules. Confirm that the system is on a rated maintenance path and that you are wearing proper anti-static gear.
  • Identify the QSFP+ port on the IBM device where the transceiver will reside. Ensure the port is clean, free of dust, and accessible for secure insertion.
  • Carefully align the Lenovo QSFP+ 40GBase-eSR4 transceiver with the port. Hold the module by its edges, avoid touching the optical connectors or gold pins, and insert it straight into the receptacle until it seats firmly with a gentle click.
  • Attach the OM3 multimode fiber cable to the transceiver’s MTP/MPO-style interface, ensuring proper polarity and full engagement. Use an appropriate fiber polarity method to maintain correct lane alignment for 4x10G channels.
  • Secure the cable management to prevent accidental disconnections. Route cables to minimize bending and maintain the recommended minimum bend radius for OM3 MMF.
  • Power on the system (or complete hot-swap procedures as required) and monitor the link status indicators. Verify that the 40G link comes up on the corresponding port and that the remote end recognizes the receiver.
  • Run basic connectivity tests, such as verifying end-to-end throughput, latency, and packet loss across the link. If issues arise, re-seat the transceiver, re-seat the fiber connection, or test with a known-good fiber pair and port configuration.
  • Document the installation with part numbers, port mappings, and fiber routes for future maintenance and troubleshooting. Maintain an inventory log for all IBM QSFP+ modules deployed in the environment.

Frequently asked questions

    A: It provides 40 Gbps optical Ethernet connectivity for IBM systems, enabling high-density uplinks between servers, switches, and storage networks over OM3 multimode fiber.
  • Q: How far can this transceiver reach?
    A: It supports up to 300 meters when used with OM3 multimode fiber, making it suitable for data-center campus links and short-to-mid-range interconnects.
  • Q: Is this transceiver hot-pluggable?
    A: Yes. The module is designed for hot-plug operation, allowing maintenance without powering down the entire system in compatible IBM environments.
  • Q: What type of fiber and connectors are required?
    A: The transceiver uses OM3 multimode fiber and a QSFP+ interface with MTP/MPO-style connectivity to carry four parallel 10G lanes.
  • Q: Is the transceiver compatible with non-IBM hardware?
    A: It is engineered for IBM systems and QSFP+ ports that support 40GBASE-eSR4-style optics; compatibility with other vendors’ equipment depends on port and standard support, so verify interoperability with your specific hardware.
  • Q: What is the module part number?
    A: IBM QSFP+ 40GBASE-eSR4 Transceiver, part number 00FE325, designed to plug into IBM QSFP+ ports and support 40G Ethernet.

This is a great ball for high energy dogs.
Color: Blue
I have a Belgian Malinois, so you can imagine the Maligator jaws. Just opened this today and let her play with it indoors. She LOVES IT. It wore her out and it’s a toy she can really stay focused on without needing me to throw or roll for her. It moves on its own! I supervised her play. I was hoping it was too big to get under the couch, but no. It goes right under it. I had to block off the gap so I didn’t have to keep getting it out from under for her. The outter “shell” is very durable! When she had resting moments, she chewed it pretty good - I could hear the material squeaking against her teeth. I was worried she was tearing it up, but nope! Not a mark on it. It’s easy to set up and operate. It needed charging before play. After hours of play, she was able to somehow unscrew the outter shell. This concerned me bc the smaller, inner ball mechanism came out but I saw it right away and was able to put it back together. So, make sure it’s screwed together tightly (which I thought I had done without breaking it) and check it from time to time to make sure it hasn’t loosened. This is a great ball for her incredible high energy drive. It gives her the work and fun play she needs to get tired, which I love. This toy is on the expensive end, but so far it’s worth it. Now we’ll see how long it lasts!

Love love it
Color: Blue
Best dog toy ever. I have a 1 year old boxer who is full of energy (understatement). This ball has provided more entertainment for us both than any dog toy I’ve ever purchased. Charge holds well and has a very resilient shell. I love it. Worth the price.

Great ball for limited entertainment. Replaceable outer shell is an amazing option!
Color: Blue, Color: Blue
Bought this for our 45lb, ball-obsessed Dutch shepherd/pit bull dog mix. I had one of these years ago with the hard shell and couldn’t be happier with the new foam shell. The new foam shell is much quieter and while our dog might put holes in it with his teeth, he doesn’t seem to ever pull pieces off. For engagement level, he found it VERY interesting at first and was scared to grab it, but once he got over that he started holding it in his mouth even when it shakes and just tries to keep it. Isn’t the best for fetch or anything as he has trouble letting it go when it is actively moving, but it makes him happy while he has it. We just make sure to monitor him while it is out. The ability to change the outer shell and just buy a replacement for the shell instead of a whole new toy is a lovely feature that makes me very happy to continue buying from this company.

Great Interactive Option
Color: Blue
To start, I have been very happy with this purchase. A couple of key points for me are durability and being able to keep my dog's attention. I have had it for almost a year, just a month shy, and she hasn't managed to get through the foam outer shell even though she tries real hard to do so. Let's just say, she's hard to find toys for because of her habit of finding the point of failure where she can pick and gnaw at until the toy is no longer safe for her to have. With this toy, she not only found her match, but it also has her watching, waiting, and even stalking. Only one small issue has recently occurred: the motor has started having an issue where the charge doesn't hold, and it doesn't remain on afterwards. I have reached out to Cheerble directly to see about replacing it since I am still within their 12-month timeframe, and they responded right away.

Quality product for the right dog...
Color: Orange
Honestly it's a really cool product well constructed and moves around on its own with several different modes. The design id brilliant with a tough rubber ball that unscrew to expose the element that makes it move in the middle. The dog won't be able to unscrew it but you can if you ever need to replace the ball for any reason but it would take some work for a dog to destroy the outer ball. Almost like "Kong" type material. The ball is about the size of a softball and the element inside is about the size of a golf ball. I thought my dog would love this but she was afraid of it, which is strange because she's afraid of nothing. Anyways I gave it to my neighbor upstairs and she has a yorkshire terrier who plays with it all the time so it all worked out great. Quality product . Good job!
