I see

         active Sup720           standby Sup720

Intake  25.00/24.99/25.00       23.83/23.87/24.00
Exhaust 27.80/27.89/28.00       24.87/24.78/26.00

Intake  21.00/21.00/21.00       20.00/20.00/21.00
Exhaust 27.00/27.00/27.00       25.00/24.81/25.00

Intake  20.38/19.64/21.00       20.00/19.42/21.00
Exhaust 26.52/25.94/27.00       24.13/23.52/25.00

Temperature is current/average/maximum on weekly basis at different 
Cat6509-NEB-A and different colocation centers.
