Sg350-28p 28-port Gigabit Poe Managed Switch Firmware Download ##VERIFIED##

Follow these instructions to rollback or update the firmware on Cisco SG350 series switch. In the example here, we will be rolling back the firmware of a Cisco SG350-28P switch to firmware version 2.5.0.83.

I found an SG350-28P in some remote location with quite old firmware 2.4.0.91 and I want to upgrade it to 2.5.0.92. My question is, can I do it in one step? Directly from 2.4.0.91 to 2.5.0.92 or it is better to upgrade to 2.5.0.X first? As the switch is in remote location, I must not brick it. Do you think there will be any issues?

Now reboot the switch so that the firmware upgrade will take effect. Navigate to Administration > Reboot, and then click the Reboot button. Or else you can also power cycle the switch to reboot by disconnecting and reconnecting the power cord behind the switch.

Once the switch is powered up, log in to the web configuration utility and choose Status and Statistics > System Summary to view the Software Information in order to confirm the firmware version has upgraded.

A progress bar appears for several minutes and after that Statistics and any errors from the transfer appear. Go to the Active Images and change the active image to the latest uploaded firmware image. Then click Apply and reboot the switch again to boot with the latest firmware.

Cisco continues to put out new SG switch firmware which adds some nice features and more stability to the product line. Several companies I have worked in the small / medium business sector are turning to these switches for their inexpensive port density and management options in an access layer switch. Since these units are available from all kinds of retailers online (and are so cheap it makes no real sense to put SmartNet contracts on them) you may find that even if you buy them at the same time, they can come with different versions of firmware installed. Working on a fleet of gear all operating on the same version of code helps streamline support and troubleshooting.

Step 3: Download the images from cisco.com (or another switch) and make them available via TFTP server. Copy the new image into flash on the switch and then set it as the active firmware image. Note that the firmware image file ends in .ros and the bootloader is .rfb. Be sure to use the image keyword at end to indicate that this is a firmware image and not the bootloader.

You could buy a 24-port Netgear ProSafe switch at a local OfficeMax, OfficeDepot, or Staples since your current switches are not in managed mode and use it to temporarily replace your core switch. If the problems quit, your core switch is bad and if they don't then I'd move the ProSafe through the other switches to see if any of them are the culprit. If you find the switches aren't the problem, you can always return it.

Agree, it's probably time for a new switch, and a managed one at that. If this is your core switch, you can't possibly be expected to manage the network without a managed switch. You can't even look at logs on that, can you? How are you supposed to know what's going on?

I am in complete agreement with you. Having unmanaged switches at the core is not a good practice. Unfortunately, this is how the network was set up prior to me coming onboard with the company 6 months ago. I am trying to get some new equipment in here, but require management approval.

I'd add that if you have a LOT of devices in your shop (we're a warehousing company, so we have hundreds/thousands of PTL devices), you might be running into the limit of the MAC table on an unmanaged switch. I've seen some in the 4K maximum devices range that can cause issues if the devices are all communicating back to a central server attached to the core switch.

I agree. Apart from the troubleshooting issue, I think you need some managed switches in this environment and get some VLANS. Like others have said, that final switch may be overloading the core switch. I hope you can correct it soon.

If I were you, and couldn't get a new, managed Cisco SG300-24 core switch, I'd remove the cover of the switch and clean it out. Do this in an area that has a RH above 30%: remove the top cover, with a good vacuum cleaner, and the hose held about 1" away from the switch logic board and power supply, suck up all loose dust and debris; then take a new, un-used 2" paint brush and run it over the board and power supply in one direction, then repeat with the vacuum cleaner. Last step is take an air duster can, and blow any remaining dust out in the same direction as you brushed the board with the paint brush. If the power supply is a separate module, remove it from the switch chassis and repeat the above, re-assemble the switch and put back in service.

Heat is the mortal enemy of all electronics. The ASA 5505 and its spiritual predecessor the PIX 506E ran hot because of lousy hardware design. I used to cannibalize old 2620's to put the 506E logic board in because it ran only half as hot. The 5505 actually runs much cooler in the accessory 19" dual-bay shelf that Cisco offers for it, which leads me to believe that it was part of the 5505's thermal design. Dust and debris accumulation, as well as a stunted MAC table in a large(r) network could very well be the cause of this switch's demise. As someone else suggested, (and I have only seen this happen once before) a genuine duplicate MAC address may exist on the network, which would also force the core switch to reboot due to a "corrupt" MAC SAT. This of course, is where a managed core switch would demonstrate its worth, but that horse is already dead. 006ab0faaa
