IMG cooling fan testing

Overview

The Dialogic IMG 1010 Integrated Media Gateway is cooled by four fans, which are automatically controlled by logic on the motherboard that monitors six temperature sensors. The Dialogic BorderNet™ 2020 Session Border Controller is cooled by five fans, which are automatically controlled by logic on the motherboard that monitors eight temperature sensors.  If temperature or fan alarms are reported, but are not currently occurring, it may be useful to verify that the fans are working properly and that the internal temperatures in the device correspond to changes in fan speed.  Verification can be accomplished using the following procedure. 

Prior to starting the procedure, ensure that EventView has been launched from Dialogic ClientView (IMG 1010) or the WebUI (BorderNet 2020), so that you can see the related alarms.

Procedure

1.  Using telnet (IMG 1010) or ssh (BorderNet 2020), login to the IMG and enter the Advanced Debug menu, "Advanced Debug>"  

2.  Type Q which will take you to the Shell prompt, "sh>"

3.  On the IMG1010 type "TEMP P" which will enable printing of the temperature statistics every ten seconds.
     On the BDN2020 type "TEMP D" which will print the current temperatures once.

4.  Make a note of the current temperature listed for each of the sensors.  If they are above temperature alarm thresholds, there should be corresponding alarms in EventView and the alarm log.  This is a Current Temp example from the IMG 1010:
