If the DAXI ALARMS LED is ON, one or more alarm conditions may be present. 
When ON, this LED has two possible states: 

 

It glows red to indicate failure of both internal fans. 

 

It glows yellow to indicate failure of one internal fan, or to indicate that the 
operating temperature of the unit is above or below allowable operating range. 

For a yellow ALARM LED, you can determine whether the problem is fan or 
temperature related by visual inspection for fan movement, or by examining the 
Alarm Status page in the DSAN CLI. For details on using the CLI, see the Cisco 
DSAN System Installation and Operation Guide, part number 4032302. 

The allowable operating temperature range of the DAXI is 0 to 50°C (32 to 122°F) 
ambient. (The operating temperature inside the DAXI is typically 3 to 5 degrees 
above ambient.) If the ALARM LED glows yellow and both fans appear to operate 
normally, the DAXI may be operating outside these limits. If the problem is 
temperature related, the unit may be operating in a location that is too cool or too 
warm, or that blocks one or more of the DAXI air vents. If so, correct this problem 
and see if the alarm clears. 

If the problem is fan related, refer the unit to your local customer support center for 
servicing or to order replacement fan kits, part number 4036946. See Customer 
Support Information (on page 23) for contact information.
