Card
|
Indicates the slot
number location of an installed card.
|
xx C
|
Displays the current
temperature in Celsius detected by a sensors on the card or fan
unit. The maximum temperature limit at which the card is shut down
appears in parentheses immediately after the current temperature.
Temperature
readings will vary by card based on the location of the card within
the chassis and the turbulence associated with moving air around,
over and through devices on the cards.
There are temperature
sensors associated with major power consuming devices on each card.
When any device on any card exceeds a pre-set temperature limit,
the fan speed is increased on both fan trays. When all sensors on
all cards are below the threshold, fan speed is proportionally reduced.
When the absolute limit is reached for a device on a card, the card
is shut down.
To display detailed information on device-level
temperature sensors, run show temp verbose.
|
Fan Upper
|
Indicates the temperature in Celsius of
the air being exhausted from the chassis. The maximum operating
temperature should not exceed +55 degrees C.
|
Fan Lower
|
Indicates the temperature in Celsius of
the air being pulled into the chassis. The maximum ambient temperature
should not exceed +40 degrees C. A temperature reading
above +30 degrees C typically indicates that the
environmental control system at the installation site may not be
capable of handling the heat load of the chassis.
