Cisco pairs A9K-20HG-FLEX-SE with the TR variant in its supported-line-card table for QDD-400G-ZR-S and QDD-400G-ZRP-S optical-module maintenance.
The official row names ports 0, 7, 8, 12 and 19. At mean sea level and 30°C (86°F), it states a one-minute maximum supported OIR duration for those listed optics.
Do not convert this specialized OIR table into a general port specification. Confirm card revision, actual optic, ambient conditions and the live Cisco procedure before removal or insertion.
This PID is a line card. Router chassis, optical modules, software licenses and service entitlement require separate exact purchasing evidence.
