Recently upgraded to Sup720s w/ 3000w power supplies,high speed fan trays and new line cards in a 6509 chassis.
I'm receiving the following log messages:
--- Version 1 low-output fan-tray is in effect.
--- Module 2 cannot be adequatley cooled
--- Module 7 cannot be adequatley cooled
--- Version 2 high-output fan-tray is in effect
Are these normal messages?

Can you post the output form the command:
show environment status all
These two messages are normal, but not in the same chassis:
--- Version 1 low-output fan-tray is in effect.
--- Version 2 high-output fan-tray is in effect
Did you have the older fan tray in the system and power it up?
These two log messages are more concerning:
--- Module 2 cannot be adequatley cooled
--- Module 7 cannot be adequatley cooled
If you have the low speed fan tray installed then seeing the messages would be fine, but if seen with the high speed fan tray then I would check to see if the fan tray has failed.

I started with an empty chassis powered down. I populated it with the new modules, which included the high speed fan tray. At no time was the low speed fan tray in the chassis with the new modules. The high speed fan tray has a green status light and all the fans are spinning. 6509#sh env status all backplane: operating clock count: 2 operating VTT count: 3 fan-tray 1: fan-tray 1 type: WS-C6K-9SLOT-FAN2 fan-tray 1 version: 2 fan-tray 1 fan-fail: absent VTT 1: VTT 1 OK: OK VTT 1 outlet temperature: 22C VTT 2: VTT 2 OK: OK VTT 2 outlet temperature: 25C VTT 3: VTT 3 OK: OK VTT 3 outlet temperature: 23C clock 1: clock 1 OK: OK, clock 1 clock-inuse: in-use clock 2: clock 2 OK: OK, clock 2 clock-inuse: not-in-use power-supply 1: power-supply 1 fan-fail: OK power-supply 1 power-input: AC high power-supply 1 power-output-mode: high power-supply 1 power-output-fail: OK power-supply 2: power-supply 2 fan-fail: OK power-supply 2 power-input: AC high power-supply 2 power-output-mode: high power-supply 2 power-output-fail: OK module 2: module 2 power-output-fail: OK module 2 outlet temperature: 42C module 2 inlet temperature: 23C module 5: module 5 power-output-fail: OK module 5 outlet temperature: 27C module 5 inlet temperature: 22C module 5 device-1 temperature: 32C module 5 device-2 temperature: 32C module 5 asic-1 temperature: 21C module 5 asic-2 temperature: 21C module 5 asic-3 temperature: 21C module 5 asic-4 temperature: 21C module 5 asic-5 temperature: 21C module 5 asic-6 temperature: 21C module 5 RP outlet temperature: 24C module 5 RP inlet temperature: 25C module 5 EARL outlet temperature: 34C module 5 EARL inlet temperature: 22C module 7: module 7 power-output-fail: OK module 7 outlet temperature: 26C module 7 inlet temperature: 24C module 7 device-1 temperature: 21C module 7 device-2 temperature: 27C

That is strange. I looked at two chassis in the lab and both reported the status s ok:
Router#show environment status fan-tray
fan-tray 1:
fan-tray 1 type: WS-C6K-9SLOT-FAN2
fan-tray 1 version: 2
fan-tray 1 fan-fail: OK
6500-1#show environment status fan-tray 1
fan-tray 1:
fan-tray 1 type: WS-C6K-9SLOT-FAN2
fan-tray 1 version: 2
fan-tray 1 fan-fail: OK
Can you reply back with the output from the following two commands:
show idprom backplane
show version | in IOS
The fan is hot swapable, can you remove it and put it back in place? Does that change the status?

Rick, I do not believe the hardware revision is the issue. I found a chassis with Revision 1 which is working:
Router#show environment status fan-tray
fan-tray 1:
fan-tray 1 type: WS-C6K-9SLOT-FAN2
fan-tray 1 version: 2
fan-tray 1 fan-fail: OK
Router#show idprom backplane
IDPROM for backplane #0
(FRU is 'Catalyst 6500 9-slot backplane')
OEM String = 'Cisco Systems'
Product Number = 'WS-C6509'
Serial Number = 'SCA031700TR'
Manufacturing Assembly Number = '73-3438-03'
Manufacturing Assembly Revision = 'A0'
Hardware Revision = 1.0
Current supplied (+) or consumed (-) = -

George, Thanks for checking on your end. When I checked the status of the fan this morning it had changed from "absent" to "OK". There are no entries in the log regarding the fan tray. The switch was not rebooted. So, it's a mystery!
