[j-nsp] redundant bad power supply

[telecom at servidor.unam.mx]

Hi, Is there any way other than replacing the power supply to stop these 
messages.. 

Jul  1 11:40:05.965  m20-1 chassisd[4479]: CHASSISD_SNMP_TRAP6: SNMP trap 
generated: Power Supply failed (jnxContentsContainerIndex 2, jnxContentsL1Index 
1, jnx ContentsL2Index 0, jnxContentsL3Index 0, jnxContentsDescr Power 
Supply A, jnxOperatingState/Temp 6)

I have a bad fan but no time nor money to replace it now.. so just making 
sure i have no alternatives

m20-1> show chassis alarms    
1 alarms currently active
Alarm time               Class  Description
2004-06-30 10:35:15 PDT  Major  Power Supply A fan failed

Thanks
