Linksys/Cisco SRW224G4 Firmware upgrade process unclear
Posted on 2013-01-04
I have an SRW224G4 v1.1 switch.
It is running:
Boot ver. 1.0.2 dated: 8/17/2006
SW ver. 1.2.2.b dated: 3/20/2007
HW ver. 00.03.00
I downloaded SW ver. 188.8.131.52 dated 2010 SRWxxxG4_FW_184.108.40.206.ros
It appears that I was able to tftp this file into the device using the serial console interface and an ethernet connection. That is, the transfer seemed to work.
I used both filename x.ros and, later, SRWxxxG4_FW_220.127.116.11.ros
But the device keeps coming up with the original SW listed above: 1.2.2.b.
I really want to get the new firmware running but suspect that either I don't know how to download it properly or that I don't know how to thereafter instantiate it properly.
I've reset and rebooted the machine to no avail.
The Serial Console and telnet menus under File Management show this:
Source File: [ ]
Destination File: [ ]
File Name: [ ]
IP address: [ ]
The last two are free form. The first two only have toggle selections:
As I recall, I downloaded the file using
Source File: tftp
Destination File: image
So, if one is supposed to "load" the new software after having tftp'd it into the box then this must be the place to do it. But just about any combination of Source File and Destination file yields that it's a bad combination.
So, I'm stuck.
The real problem with this box is that the GUI interface isn't working and I hope the new firmware would fix that.
I have read that using a user name of the default "admin" will cause the GUI interface to not work. So, I've changed the user name. But that didn't help.
So, at this stage, how *IS* one supposed to upgrade the firmware and make it "stick"?
