ACE 4710 not responding


We have to ACE 4710 device in our network and we have facing device hung issue in our Primary ACE. We are not able to get management access or direct console access to the device when the issue is happened and also we are not able to reach the vlan interface IP or/VIP. Please find the below output we got through monitor that we are connected to the ACE.

Booting localboot(c4710ace-t1k9-mz.A5_1_2.bin)

kernel=(hd0,1)/c4710ace-t1k9-mz.A5_1_2.bin ro root=LABEL=/ auto console=ttyS0,9

600n8 quiet bigphysarea=32768


Uncompressing linux Ok, booting the kernal.

Issue is resolved after we manually rebooted the ACE. We have collected the sh tech after the reboot.

Software version : A5 1.2

Kindly suggest what may cause this issue.

Thanks in Adavance.




Hi Ranjith,

it could be a problem with the flash drive of the ACE.  Please gather a console output when the ACE is booting.

Just connect the console cable like you do to any Switch or Router and get the output from there.

After the reboot, ACE did not generate any core dump and does not anything under last boot reason.

I would recommend to monitor the behavior and if the issue re-occurs, open a TAC case right away and console to try to get some outputs and take a look of the messages when the situation happens.

Hope this helps!
