Cat6500 temperature

Hi,

catalyst 6500 is saying that the max. temp. is 40 C from datasheet.

so I checked my device temperature.

***

I found several asics are very hi temperature.

are they acceptable ?

Enter the command "sh env al".  If no additional errors then you are fine.

thanks leolaohoo

I'll check show env all.

Do you know that if  asics temperature were over 40C on "show env temperature", we could get cisco's supports ?

so CCO said " Certified for operation: 32° to 104°F (0° to 40°C) " on http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Chassis_Installation/Cat6500/01over.html

The temperature in the data sheet talks about the OUTSIDE temperature relative to the switch.  The output you've shown is from the INSIDE of the switch.

thanks leolahoo.

I do understand!

thank you for your kidness.

Hi,

Can anybody explain what is VTT and EARL temperature?

Highlighted

Mostly every important modules in these modular switches like 6500 has temperature sensors to guage there temperatures and provide alerts in time.

EARL stands for Enhanced Address Resolution Logic. It is gives the 6500, the ability to do packet forwarding in hardware. EARL is nothing but a set of ASICs or CHIPs that does forwarding lookups at hardware level. The same job that a CPU or Proccesor does. But by doing forwarding lookups in hardware and not involving the CPU, helps us to achieve the Millions Packet/Sec rate.

The VTT(voltage termination) module are three replaceable voltage termination (VTT) modules (WS-C6K-VTT-E=) that provide reference voltage for bus signals.

These temperature sensors are for these two hardware modules/ASICs to monitor.
