What is the exact model of the switch?  The output shows the switch is being forced to load the IOS meant for a LAN Lite model.

[naveen.singh11]

Switch Model No : WS-C2960-48PST-S V05

Catalyst 2960 Series SI POE-48

Switch Model No : WS-C2960-48PST-S V05

Ok, the behavior of the switch make sense:  Someone loaded the wrong IOS into the switch.

The switch is a "plain" 2960 but the switch is forced to load an IOS image meant for a 2960 LAN Lite, hence, the switch is refusing to boot the IOS.

lanlitek9 seems to be the right image for the Catalyst 2960 PST:

https://software.cisco.com/download/release.html?mdfid=282644731&flowid=2564&softwareid=280805680&release=12.2.55-SE11&relind=AVAILABLE&rellifecycle=ED&reltype=latest

I see from the output of "dir flash:/" that only about 4 megs are used - the .bin file alone is almost 8 megs, while the .tar file (containing the .bin and the web GUI files) is 11.5 megs in size.

My guess is someone deleted the .bin file from the c2960-lanlitek9-mz.122-55.SE10 directory (what does "dir flash:/c2960-lanlitek9-mz.122-55.SE10" output?)...

Hi sir,

Now switch showing weird characters after I opened it in hyper terminal, even i didn't upload .bin file yet. I tried to use Mode button also but it remain same.. kindly check attached file..

[Iulian Vaideanu · Accepted solution]

Weird characters are usually caused by baud rate mismatch (between what's set on the switch and how the serial port is configured in the terminal software) - if you "set BAUD 57600" on the switch then you should reconfigure the COM port accordingly in HyperTerminal.

c2960-anlitek9-m.122-55.SE1.bin (besides being misspelled, but that's not an issue) is way too small to be complete, so this is most likely why the switch fails to load it.

From the "switch:" prompt try "boot flash:/c2960-lanlitek9-mz.122-55.SE11.bin";  if the switch boots successfully, do "conf t", then "boot system flash:/c2960-lanlitek9-mz.122-55.SE11.bin" and "wr mem", then delete the incomplete file (c2960-anlitek9-m.122-55.SE1.bin).
