VTT threshold recommended values

[m.arancibia]

Hi everybody,

I am seeing this VTT enviroment values (extracted with the command show environment alarm threshold) in 3 7600 differents boxes.

VTT 1 OK: OK

  threshold #1 for VTT 1 OK:

    (sensor value != 0 ) is system minor alarm

VTT 1 outlet temperature: 36C

  threshold #1 for VTT 1 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for VTT 1 outlet temperature:

    (sensor value >= 115C) is system major alarm

VTT 2 OK: OK

  threshold #1 for VTT 2 OK:

    (sensor value != 0 ) is system minor alarm

VTT 2 outlet temperature: 35C

  threshold #1 for VTT 2 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for VTT 2 outlet temperature:

    (sensor value >= 115C) is system major alarm

VTT 3 OK: OK

  threshold #1 for VTT 3 OK:

    (sensor value != 0 ) is system minor alarm

VTT 3 outlet temperature: 33C

  threshold #1 for VTT 3 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for VTT 3 outlet temperature:

    (sensor value >= 115C) is system major alarm

I want to confirm if this values are correct, because looks elevated (100C and 115C), or what values are recommended ...if it possible change it.

Rregards.

Hi,

This sensor vlaue is correct and this is maximum allowed temperatures for the sensors which is defined as minor and major alarm

There are two alarm types: major and minor.

• Major alarms indicate a critical problem that could lead to the system being shut down.
  
• Minor alarms are for informational purposes only, giving you notice of a problem that could turn critical if corrective action is not taken
  

The system sensors set off alarms based on different temperature threshold settings. You can determine the allowed temperatures for the sensors by using the #show environment alarm threshold command

I verified on LAB and found below detail,

switch 1 VTT 1 OK: OK

  threshold #1 for switch 1 VTT 1 OK:

    (sensor value != FALSE ) is system minor alarm

switch 1 VTT 1 outlet temperature: 32C

  threshold #1 for switch 1 VTT 1 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for switch 1 VTT 1 outlet temperature:

    (sensor value >= 115C) is system major alarm

switch 1 VTT 2 OK: OK

  threshold #1 for switch 1 VTT 2 OK:

    (sensor value != FALSE ) is system minor alarm

switch 1 VTT 2 outlet temperature: 30C

  threshold #1 for switch 1 VTT 2 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for switch 1 VTT 2 outlet temperature:

    (sensor value >= 115C) is system major alarm

switch 1 VTT 3 OK: OK

  threshold #1 for switch 1 VTT 3 OK:

    (sensor value != FALSE ) is system minor alarm

switch 1 VTT 3 outlet temperature: 33C

  threshold #1 for switch 1 VTT 3 outlet temperature:

    (sensor value >= 100C) is system minor alarm

  threshold #2 for switch 1 VTT 3 outlet temperature:

    (sensor value >= 115C) is system major alarm

When the voltage termination (VTT) module reaches 100C, the System will throw the minor alarm, and when it reaches the 115C, it wil show major alarm

Hi Aru,

Thanks for your answer, I already had this information but I want to confirm if this values (100C and 115C) are

fixed and is not possible or necessary change it.

Hi,

This is default value which is set already and there is no need change it.

Regards,

Aru
