Flex chassis CMM Update 2.5.0 problem

2020-06-09, 6:12 AM

HI,

 

We have new  flex chassis with single CMM module, we upgraded the CMM firmware 2.5.0. And after successfully updated the firmware reboot the CMM.

 

But CMM did not come up. and we checked the CMM backside there is power & Active LED is green. NO FAULT LED.

 

We try to physically reseat the CMM but still CMM ip is not pinging.

 

Lastly we reset the CMM to factory default configuration but still cmm is not ping with default IP address.

 

So i want to know the new firmware 2.5.0 has some problem.

 

NOTE: we upgraded the cmm firmware from 2.1.0 to 2.5.0

 

Please give me the solution ASAP.

 

Thanks

We have started to use 2.5.0 in lab , and don't see issue when updating from old version, and also don't find flashing issue from customer.If the reset to factory default doesn't work for you , you may need open ticket to Lenovo support to send engineer onsite check.

 

 

One more thing, reset to factory default , press the reset button at least for 10 seconds , make sure you have pressed the button as long as 10 seconds.

If you load CMM2 to default , it still cannot ping the IP address. 

  1. please make sure you IP address and netmask match same with CMM2 IP address and netmask.
  2. if still cannot ping , you need open case to Lenovo support and try replace the CMM2.
  3. We can confirm the FW 2.50 no known issue releated the ping issue.
