MS Temperature Thresholds

Overview

A switch may stop working when it reaches a given temperature. This is known as a Critical Temperature. A Critical Temperature Threshold is the temperature at which a switch will generate an alert that permanent damage may occur.  Every switch model and family can perform at different temperature limits according to its hardware design and features offered.

A critical temperature alert will be triggered if a switch detects that it is operating at a critical temperature. Critical temperature is a scenario that requires careful consideration of the operating environment of the switch. The switch is polled every 30 seconds and once the critical temperature threshold has been reached, on any of the temperature sensors within the switch, a critical temperature alert is generated.  The alert will be cleared once there has been a successful poll that returns a value below the critical temperature threshold of all the temperature sensors within the switch.  This alert is supported for the following models :

  • MS120-24P/48LP/48FP
  • MS125-24P/48LP/48FP
  • MS130-8X/8R/12X/24P/24X/48P/48X
  • MS210-24P/48LP/48FP
  • MS220-24P
  • MS225-24P/48LP/48FP
  • MS250-24/48
  • MS320
  • MS350-24/24X/48
  • MS410-16/32
  • MS450-16/32

It's useful to know what the Critical Temperature Thresholds are according to switch family, model and number of ports. This document covers the critical temperature thresholds and values including all the temperature sensors internally within the switch.
