Reset BAUD rate on SM-ES2-24 Switchmodule

[wesserc]

Hi. 

As read by the title I have created a missmatch between my switchmodules baud rate and the correct line speeds.

This makes the switch totally unresponsive with all possible terminal speeds.

using "service-module gigabitethernet 1/0 reset, reload or shutdown" seems to do nothing. 

Any otherway to completely reset the Baud rate settings of the module?

what is the Router model here :

what is the error or message you getting when you try to connect to module using session ?

some reference document :

 - According to this document : https://www.cisco.com/c/en/us/td/docs/routers/access/interfaces/software/feature/guide/eesm_sw.html , the flash_init command resets baud rate to 9600 , but take care it will probably also wipe the configuration.

Connecting to the switchmodule only yields random characters  since speed doesnt match.

The flash_init command is only useable if I could access the switch.

The Router is a 2911 with c2900-universalk9-mz.SPA.156-3 ios.

                               - Try  tapping the space bar when you get those.

Only results in more characters.

                - Yeah, that procedure may only work during boot , when when the garbage starts appearing.

ok you mean you are not able to access with below setting.

putty setting:-
port:comx
speed:115200
data :8 bit
parity:none
stop bits: 1bit
flow control: none

1. router# set baud 57600
2. change putty setting speed 57600
3.copy xmodem: flash: c2900-universalk9-mz.SPA.156-3 ios
4. enter
5. select if you are using teraterm then go to file-transfer-emodem-send-select file
6.once file copy done set baud back on 9600
7.boot flash: c2900-universalk9-mz.SPA.156-3 ios

Hope this will help you...

Thanks,

Im able to access those fine as none of them concern the switchmodule.

The tty line that the servicemodule uses can only be set to speed 9600 or 115200, while the switchmodule was previously set to 57600.

I need a way to reset the switch, not reinstall the ios of the router.

Please below command output as well.

ser sm 1/0 log show

  A reset is the last try, into a different slot maybe else the module seems to be bad.

you can follow the below discussion as well..

Can you post show run (full output or check below )

#service-module gigabitEthernet x/x Status

This show you vty lines used for that module

example :

Service Module supports session via TTY line 44

check what config you have in vty line 44

still issue post below outout :

show run

show modules
