Check Fan Rotation. Inspect 
the fans located at the sides of 
the enclosure. Are the fans 
rotating? Check the 
temperature (select Chassis / 
Temperature Alarms on the 
Device Info web page).  

Check that the unit has been 
installed with sufficient space 
allowed for air-flow (see 
Chapter 2, Installing the 
Equipment). If the ambient air is 
too hot, additional cooling may 
be required. 

Possible break in the DC supply 
from the PSU module to the 
suspect fan(s). Call a Service 
Engineer. 

Use Table 7.4 to aid in diagnosing a input card fault. 

1 

Check the status of the 
Input Card. Is there a 
modulator failure alarm being 
shown on the Status web 
page? 

If the unit indicates a critical 
failure, call a Service Engineer. 

If no modulator failure alarm is 
shown, go to Step 2.  

2 

Check the status of the 
input ports. Do the ports 
reflect the reported status? 

Discuss the perceived problem 
with Ericsson Customer 
Support. 

If the port is not providing a valid 
input when it has been enabled, 
call a Service Engineer.
