Thermal Mitigation
The following table provides a description of thermal mitigation levels and throughput performance.
This applies to the IR1835 with dual P-LTEAP18-GL pluggable modules and the WP-WIFI6 pluggable
module.

Hardware
IR1835 plus WP-WIFI6
Dual P-5GS6-GL
Under normal conditions both 2.4 and 5 GHz radios of the WP-WIFI6 pluggable operate in 2x2 MIMO mode,
with antenna ports A and B active. Upon exceeding the ambient temperature and airflow levels indicated in
the thermal mitigation table, both 2.4 and 5 GHz radios may throttle to 1x1 SISO. In 1x1 SISO mode only
antenna port A is active, and each radio is restricted to single spatial stream data rates.
