how to install StarTech.com MSA Uncoded SFP Module - 100BASE-LH

  • Power down the device or ensure the system supports hot-swapping before installation. Remove the existing SFP module if applicable, or identify the vacant SFP slot in the switch or router.
  • Insert the StarTech.com MSA uncoded SFP module into the appropriate SFP slot until it seats firmly with a gentle click. Confirm the module is securely connected and aligned with the host port.
  • Connect a single-mode fiber optic link between the two network devices using the correct SMF cable and the appropriate connectors as required by your deployment. Ensure the fiber is clean, lanes are properly seated, and the link is free of kinks or damage.
  • Configure the host device to operate the port at 100 Mbps Ethernet if automatic negotiation isn’t supported. Verify that the port recognizes the SFP module and that the link comes up with a valid speed and duplex setting.
  • Monitor the link status via the device’s management interface. Use the SFP’s Digital Diagnostics Monitoring (DDM) data, if available, to verify optical power levels, temperature, and other key metrics. Run a basic throughput test to validate end-to-end performance across the 80 km link.

Frustrating but crazy fun
Color: blue, Color: blue
Maybe it’s just me and my breed of dogs but I bought 4 and within 30 seconds of placing them all down on the floor at the same time, we were down to 3… I have 3 German shepherds and a mastiff… 1 shepherd licked once and then took the whole thing in her mouth and ran out the doggy door…( if you own a German shepherd I hope this message finds you) it’s been an hour and I still can’t find the new bowl…so now we are down to 3… I blended some wet dog food and mixed with Greek yogurt for one… texture was smooth but the ball wouldn’t move fast enough for said shepherd so after some adjusting of the consistency… I still couldn’t figure it out…so as one pup is licking one ball, I grabbed the pumpkin puree and yogurt and it was still too thick… so I watered it down with a little bit of Vienna sausage juice…which now of course the crew is waiting for Vienna sausages to be dispersed among this group of terrorists….and as I’m dispersing, I noticed the bowl of wet dog food was upside down and the pumpkin puree bowl was on its side leaking orange liquid out the top… I’m still working on consistency for the remaining bowl… (mind you, we have already had breakfast which consisted of sausages from the oven as we love beer brats for breakfast… 3 cans of wet dog food that all the babies line up for and are spoon fed -and a couple pieces of cheese as I was prepping dinner) ok so now I have a runnier consistency with adding that sausage juice…got it to where I could move the ball pretty easily but then once again it got too dry and the ball just kept getting licked and nothing was sticking to it…when taking the device apart, I noticed that the liquid has no problems being licked up but the problem is that the thicker product gets stuck on the sides and the ball can’t pick it up for some reason… it needs to be nectar consistency or thinner for my family…as I’m seeing… during this whole time I’m mixing different consistencies on my counter… holding on to one with my foot as they do not stand up against large breed mouths, slide all over and also trying to make sure they stayed safe in the home as these were not the cheapest…and holding one in my hand for my special needs shepherd…these things were slipping all over the floor. They are heavy and feel durable but someone back me up here… I have learned so much about my breed of the GSDs… but my life has changed so much since having these babies because learning what can stand up to these dogs is a daily-no-HOURLY TASK. My dogs do not find enrichment activities fun. They bore easily and that’s probably my fault… so when I saw these enrichment bowls I was pumped!! The treat mats, (were shredded within minutes of realizing we couldn’t get treats out quickly) the boxes with the *whack-a-mole” cheese stick games…the poor Amazon box that I so carefully cut holes into did NOT see my shepherds mouth coming… these special toys that the dogs have to roll around to release a treat… no. No. No. I’m still finding chunks of THAT poor toy… these should not be called ‘slow feeder dog bowls’ liquid treats yes but the videos of the dog owners making the yummy stuff to go inside need to be a little more specific… as we all know, all dogs are different… but this product was supposed to entertain the puppers for a little bit but 24 hour supervision is required in this home which is not ideal… I need to get a few things done daily without the assistance of 3 Velcro dogs… impossible with the new enrichment bowls… I’m not going to return them, my dogs love them once they understand to stay put and lick but my dogs consume things so fast that now it’s just another activity to do with them daily which is fine… but if you have certain breeds it might save your couches and shoes from being chewed but now with the way I have to monitor these things and constantly refill the bowls…( my dogs had them cleaned out in about 3 minutes each) all in all, this was not a smart purchase for me as it’s now added more work to our already busy routines… I can only do 1 star…aftermath photos

Good for a laugh at least and a messy kitchen
Color: black
While design, quality, and ease of cleaning are great!! These are not for highly food motivated dogs and puppies. My senior dog (100lbs) took a couple licks, he immediately proceeded to pick it up as one unit and carry it to his bed where immediately tore it apart to get to the good stuff. ~ I will say that it is durable and did not fall apart as he carried it. My 7mo old puppy (60lbs) was intrigued and quickly impatient and was able to flip it over and while this only made a little pumpkiny mess, what he did next was hysterical! He picked it up on the edge and threw up in the air and the mess surprised even him but only for a moment. He promptly did it again and on the third time he was able to break the top loose from the bottom and quickly cleaned up the toy and the mess on my kitchen floor and cupboards. Fair warning for those with energetically food motivated labs!! These have since been donated to local shelter with the same warning.

Great for dogs
Color: blue
My dog is obsessed with this! I put plain yogurt thinned with homemade broth in it and he’s entertained for a good 15 minutes, as well as being fairly calm afterward.

Great bowl, would love this in a larger size
Color: blue
This is a great way to treat your dog! I filled it with a bit of plain yogurt drink diluted with water, and my dog absolutely loved it. It only took him about 3-5 minutes to finish it, but he’s about 60lbs, so maybe a bigger size bowl would be better for him. Max capacity of this one is 190 ml. You do have to monitor your dog with this bowl - mine tried to dismantle the bowl when it was empty, trying to get more out of it. Overall I think it’s a fun way to get your dog to drink a little bit more with diluted yogurt, broth, etc.

My dog loves it!
Color: black
Kudos to whomever created this! I have a super attached (med) dog that follows me from room to room alllll day. The first time I put this down he went right for it and didn’t even notice i had left the deck. He is very food driven. I used bone broth and pumpkin puree, which was a hit but once I used the apple sauce… HUGE hit. My only complaint is that it doesn’t come in an XL size. My dog can empty it in under 3 minutes..so he doesn’t get relaxed or sleepy! it does splash out a bit from the top so I use it on his food mat or outside..my sister can’t stand the noise the ball makes. I wasn’t diluting enough so the ball doesn’t move smoothly in the video, but it really does work! The cover is very well made and sturdy. I didn’t notice it sliding around at all. My dog also did not try to get the ball out (loves to tear apart toys) or tip it over, but I could see that happening. I wouldn’t use unsupervised unless you have a small dog. Please make a larger size!!!!
