Temperature Sensor

A router equipped with the Cisco 3270 Rugged Router card includes a high-precision digital
thermometer and thermostat (DS1631). The temperature is sampled every 30 seconds. A warning is sent
to users by means of SNMP traps and by flashing the overtemperature LED if temperature falls below
-40ºC or exceeds +95ºC until the temperature falls back to its normal range.
Note The signal and LED are available only on the Cisco 3270 Rugged Router card, not on the Cisco 3200
rugged enclosures.
