6500 fantray cooling configuration

Hello,

I have installed a new WS-6724-SFP line card in a WS-C6509 chassis and it will not come up due to the following error code:

%SYS-2-FAN_INSUFFICIENTCOOLING:Module 7 cannot be adequately cooled

HAVC6502> (enable) sh environment cooling

Chassis per slot cooling capacity : 37 cfm

Fan tray(s) cooling capacity :

Fan Model Ver Cooling Ambient FanStatus

capacity temp

---- ------------------- --- -------- ------- ---------

1 WS-C6K-9SLOT-FAN 1 340 cfm - ok

Slot cooling requirement :

Slot CardType Cooling

---- ------------------- -------

1 WS-X6K-SUP2-2GE 30 cfm

3 WS-X6408A-GBIC 30 cfm

4 WS-X6516-GBIC 30 cfm

5 WS-X6516-GBIC 30 cfm

6 WS-X6516A-GBIC 30 cfm

7 Unknown 70 cfm

8 WS-X6148-RJ-45 30 cfm

9 WS-X6324-100FX-MM 30 cfm

It appears that the chassis only provides 37cfm per slot for cooling, regardless of the line card demands. There is ample cooling available, but the maximum of 37cfm is a hard set restriction. Can this be configured to be increased to the 70 required by the line card? Or does this require an enhanced 6500 chassis?

Re: 6500 fantray cooling configuration

Phil,

Ultimately your problem is that the 6700 series blades are only compatible with a sup720. More than that, a sup720 requires a high speed fan tray which is probably what the slot cards check for first.

You need a new sup and fan tray, but not necessarily an e-series chassis. CFM is not configurable to my knowledge.

Hope that helps.
