Alarm Troubleshooting
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.
