Hello all,
I have configured a stack switch with 3 members (model B5G124-48P2), and all of them have the same firmware version: 06.71.05.0008

Today, el switch member # 3 began to reboot with no reason. The log of that was the following:


<160> MAR 29 09:33:55 130.40.34.58 SIM[83789648]: broad_hpc_drv.c(2686) 1809 This is from member 3 %% unit = 1, CBPCELLCRCERRPTR 0x00000001
<160> MAR 29 09:33:55 130.40.34.58 DRIVER[189196800]: broad_system.c(5211) 1810 This is from member 3 %% 4 CBP cell CRC errors detected on SoC unit 1

I checked the power source and is working normally, the stack cables are perfectly connected, the temperature is ok and the watts consumption por PoE are in the levels:

IDF_P7(rw)->show inlinepower
Detection Mode:auto

Unit   Status   Power(W)   Consumption(W)   Usage(%)   Threshold(%)   Trap      Mgmt Mode
----   ------   --------   --------------   --------   ------------   --------  ----------
1      auto     375        67.200           17.325     80             enable    realtime
2      auto     375        60.400           16.0       80             enable    realtime
3      auto     375        54.500           14.150     80             enable    realtime

So, I don't know if the problem is related to the firmware version or I have to consider some other things related to the power.

Can you please help me to solve this situation?

Thanks in advance.

There is probable hardware failure here. I suggest that you open a GTAC Support case for this, making sure that you include the 'show support' output, and the full current.log file extracted as outlined in KB 5487 (http://bit.ly/1pOU3VK).
