Configuring the Thermal Profile for Fan Tray Operations (APX 8000)

Thermal status reporting

Thermal status reporting

A power-on self test (POST) is run on the fan tray of the APX 8000 during the BOOT loader and during the operational load. If the fan tray POST fails, the POST failure status light (amber) flashes 10 times and the following log message is generated:

LOG emergency, Shelf 1, Slot 42, Time: 15:23:57--

post failed, type (10)

In addition, two new commands are supported for displaying information about the fan tray and the unit’s thermal status. Both commands, along with the automatic fan tray speed regulation, are available on both shelf controllers in a redundant system.

Fanstatus command

The fanstatus command displays fan tray status information such as the fan revolutions per minute (RPM), status (OK or BAD), and the unit’s ambient temperature. Note that the current fan mode can be displayed as either full speed or low noise. For example, the following output shows the fan mode set to full speed with an ambient temperature of 33 degrees Celsius

(91.4 degrees Fahrenheit):

admin> fanstatus

APX8000 Fantray status

Fantray ambient temperature: 33 C

Current fan mode: Full-speed

The following command output shows the fan mode set to low noise with an ambient temperature of 27 degrees Celsius (80.6 degrees Fahrenheit):

admin> fanstatus
