Cisco 897 VAMW temperature

Hi,

I have a fiber connection from my ISP which terminates in a Cisco 897 VAMW. It has been running fine for several month, but recently we started getting very high packet loss (60%) when traffic hits 20Mbps.

Our ISP checked the fiber and it was without errors - so they replaced the Cisco 897 VAMW with a new one - and it has been running fine for nearly 1 week now, but last night we started seeing packet loss again. 

 

2 routers with the same error, i find unlikely. I rather suspect it could be related to a heating issues on the site. Reading the specs for Cisco 897, it operates a 0 to 40 celcius - and i suspect, it could reach higher temps inside after some days. Is the 897 router very sensitive to high temps?

A have a 2960T switch and a Watchguard XTM25 unit installed at the same location right next to the 897 router - and they work without issues.

Hello,

 

post the output of 'show environment temperature' and 'show interfaces x' where 'x' is the WAN interface connected to your provider...

Hello,

 

there is always a possibility for bad venting or high temperatures to cause packets loss, however, you can only see that from the output I requested. I would suggest to ask your ISP to look at that output...

Yep, i have already opened a new case with my isp.
