I have a problem with 6 SLM2048 (and 2024) switches we purchased last year. At first they seemed to work fine, but now I'm rebooting them about once a week at minimum. The problem is that ports start going dead. An affected computer will sometimes still be able to ping other machines, but no other traffic is allowed through. Rebooting the computer, giving it a new IP, new cables, etc. doesn't work. Rebooting the switch usually works for about a week or so, then ports start going dead again and another reboot is needed.
we had the same situation. SLM2048 with Firmware 1.0.1
I noticed that HP ThinClients get now IP Adress from DHCP Server. Also fix IP does not work.But networkcard showed connected. I first investige the servers i ven analysed the networkcableing with an electrical specialist.
Power off the switch helped for somedays.
No i was in the forum and decided to upgrade the Firmwar to version 18.104.22.168 the latest.
the switch was rebooted from http upgrade.
The switch is working , but now i can´t log in again. It says wrong password.
i just read in another posting . try admin admin like after a reset .
now i can log in the switch.
why is such an information not included in the firmware upgrade readme file ????
have a nice day
Yeah, that was one of the combinations I tried, but still no luck. I think I'm going to have to take some time and call Linksys tech support.
I have problems to log in with firefox 3.6.2 . I instead used IE8 and put the WEB URL of the switch to the secure sites.
there are problems with IE8 with older Firmware. the new Firmware 2.0.08 is running with IE8 and Firefox.
So I would try also IE6 or & or maybe opera...
I can get to the page fine, no problems. My real problem is the ports going dead after a while. I've read some pages that state this might be due to cheap Chinese parts being used inside some of these switches. They're liquid in nature and when they heat up, they swell and lose contact. I'm wondering if that could be the case for me.
No one rezolve this prroblem ?
Is under CISCO to do crap like this to customers.
We have a lot of isues because this switch dont work proprely.
I WILL NEVER BUY A LYNKSYS PRODUCT .And i will advice all the ppl to skip this bulshit brand (entry level ?! no is worst level)

We purchased 4 of these switches at the end of 2009 and they just seem to drop ports offline.
Nothing resolves the issue until you reboot the switch, then the ports come back online again. Its almost like an "ERRDIS" state on a Cisco switch, but shutting the port off and back on does NOT clear the condition. I don't think this is related to components or it would manifest itself more randomly, I think its either a design issue with the hardware itself or a software issue with the IOS.
I would try the new IOS which they just released recently. Its version 22.214.171.124
I have the same exact issues with one we purchased a few months ago. After a few days of being online, any large amount of traffic on the switch will cause it to start dropping packets like crazy - our up/down network monitor go nuts with timeouts.
After this happens, attempting to connect any new devices to the switch fails. The lights light up on the switch, but in the GUI the port is inactive and although the machine connected can tell there is a link, no data will pass through the port. This situation can be resolved by rebooting the switch (terrible solution).
Definitely not ever buying or recommending these again - go for the real Cisco stuff, or choose another brand...
Yeah, I'm looking at replacing a large number of smaller switches in the next few months and I had someone recommend some more of these small Linksys/Cisco switches to me. I told them to forget it, I'll be checking out HP or 3Com if I can't shell out the cash for an actual Cisco product. I'm more than little unhappy with these switches, and it appears I'm still having the same issues even after calling Cisco support and them being very nice and sending me all "new" switches. One of them was new, the other 4 were refurbs, and of those, at least one was older hardware than everything I'd just sent back to them. As I said, it doesn't appear to have helped, though. Tons of dropped packets on my network, my monitoring software watches stuff bounce up and down all day long.
I worked for HP in Network Support for 10 years and HP switches are pretty darn reliable and have a lifetime warranty.
They are not Cisco and their applications are not as diverse, but I have seen HP switches sit and run without any problems for 2-3 years between reboots.
I really like these SLM units in features and pricing, but they need to get this port issue resolved. A unreliable switch is a plague on humanity, and causes endless sleepless nights. If these are just sitting in a closet servicing user PC's you can get away with a reboot in the middle of the night. We had them connected to servers that are up 24 x 7 and rebooting a switch is not something you just do randomly when you have an issue. I have to clear a switch reboot with our Change Control process and it takes days to get permission from all parties involved.
We yanked them out and replaced them with Cisco 48 port units that we had freed up from a previous project.
Hello i´m back !
It seemed all was ok after upgrading to firmware 126.96.36.199 but the error came back to soon.
I have more dead ports then before. Only the power off mehtod brings the ports back to life.
Also we notice that the performance while copying files across the LAN was very very slow.
In the Management console Overview the Port is shown as grey colored. But I can manage this port by right clicking. I can change some items but the port does not come back. No data is transported...
I no will give Cisco a Service request...
Wow. This is an awesome post. I bought one of this babies 2 weeks ago. I got this issue since last week. At first I was thinking that probably it was a PC connected to that port, but after reading this post definitively it's a switch issue. It already came with Firmware version 188.8.131.52 . This is my very first experiece with Cisco and sadly it was not a good one. So I'm pointing to a full refund. Hope this issue could be fixed since I really like the management GUI of this baby.
Thanks for sharing all your comments.
i had an telephone call with CISCO Support last week. The guy confirmed he had heard some issues with the SLM2048 .
I´m very angry, usually we use the srw versions. never we had such trouble . I hope Cisco comes back to me with some "good" news soon.
i´ll keep you informed....
