Upgrading firmware on the Linksys SRW2024 without using the web. Requires first updating the boot code. Is that it is much faster than using xmodem.

This is useful if, for example, the web interface keeps resetting the connections. Upgrading the firmware requires first updating the boot code, and the regular console in the earlier firware doesn’t have support for flashing the boot code. However, there is a hidden IOS-like cli available, that makes it possible to upgrade the boot code over tftp. An additional benefit is that it is much faster than using xmodem. The steps • Setup a tftp server on your machine, serving the files srw2024_16_boot-101.rfb and ls20xx-12230.ros (download from ) • Connect your computer to the switch using ethernet and serial cables. • Boot the switch.

• Log into the console. • On the new promt, type lcli and press enter. • To upgrade the boot code, type copy tftp:// /srw2024_16_boot-101.rfb boot • Then upgrade the firmware: copy tftp:// /ls20xx-12230.ros image • Lastly, restart the switch: reload That’s it. As an aside, please note that the web interface only works in Internet Explorer, so if it seems like it doesn’t work, it’s probably because your’re using another browser. Post navigation.

Decompressing SW from flash HOSTG_rscode_file_load: could not load file Perform WARM BOOT. When I go to the Hyperterminal an press 'Downloading from Xmodem' and select Send File. Select the firmware image (older FW) and choose Xmodem as the protocol, then I get an error:-( Is here anybody reactivated the switch from this loop with an older fw? Thankyou K.R.

Just wanted to give an update for the users still using or have a SRW2016 or SRW2024 switch stuck in a loop. Since you cannot access the switch via telnet or http you must connect through the serial/console port and load an older rev of the firmware to get the switch out of the loop. It appears the older versions of boot code do not like the 1.2+ firmware.

The easiest way to get back normal operation of the switch is, as stated above. Load an older rev of the firmware through the serial port with Xmodem. Once you have an operating switch, you can then load the newest rev of boot code, reboot, then load (through serial again) the latest 1.2+ firmware. There are already posts on here going through the step-by-step details of this process, but if you find yourself lost, email/msg me and I will help. Thanks -Adam. I had my SRW2024 stuck in a loop after upgrading to version 1.2.2. I was successfully able to downgrade back to 1.00.86 using the XMODEM method and breaking the loop after the POST.

I did not have access to a LinkSys cable. I first tried a serial cable, then a null modem cable and finally had to build a custom cable to connect to the console port. Pinouts are 1-1, 2-2, 3-3, 4-4, 5-5, 6-6, 7-7, 8-8 and 9-9. Each pin is straight through.

Everything I have read indicates that I need to upgrade my boot code as well as the firmware. The problem is I cannot find where to download the latest boot code. The LinkSys site redirects to Cisco when you search for the SRW2024. The Cisco site allows you to download 3 versions of the firmware, but I cannot find anywhere to download the boot code. Mann mera full song download from table no 21. Can anyone assist me by pointing me in the right direction or providing a url link to the latest boot code. OK I upgraded my srw2016 with out any problems and with out needing the console or telnet step one get the files runtop_boot-101.rfb and ls20xx-12230.ros runtop is hard to get Cisco removed it from the downloads damning you to fail but you can get it with the help of Google. Step two get a Tftp server I got TFTP32 but you can use just a bout any.

And copy the run top boot file to is directory step three in the management tab on the web interface select file download and point it to the IP of the TFTP server select boot code, put the file name in runtop_boot-101.rfb and let it upload it will take a min. Step three at this point the TFTP download option will not let you update the firmware, its says version mismatch and that you have to reboot before the upload, but if you do the it will not BOOT and you will have to load firmware with hypertermel and Zmodem with a serial cable yuck! BUT if at this point from the management Tab you select HTTP download and point it to the firmware file (ls20xx-12230.ros) it will take it, however it goes slow! Mine went at 8k and took about 5min to transfer. After the transfer is complete you can reboot. If you have IE7or8 you mush enable always allow popus from this site the transfer is in a popup here is what I started with.
