DescriptionFeature
The chassis has a built-in, front-facing, passive RFID
tag that uses Ultra High Frequency (UHF) RFID
technology and requires an RFID reader with
compatible software. It provides auto-identification
capabilities for asset management and tracking. The
RFID tags are compatible with the Generation 2 GS1
EPC Global Standard and are ISO 18000-6C
compliant. They operate in the 860- to 960-MHz UHF
band. For more information, see Radio Frequency
Identification (RFID on Cisco Catalyst 9000 Family
Switches).

Fan Tray Assembly Overview
A Cisco Catalyst 9400 Series fan tray assembly—
• Is composed of a fan tray and an adapter that is attached to the fan tray. It is responsible for cooling the
entire chassis and interfacing with environmental monitors to trigger alarms when conditions exceed
thresholds.
• Has side-to-side airflow for balanced airflow across the inserted cards. When facing the front of the
chassis, airflow direction is right to left.
• Can be installed and removed from the front and the rear.
• Has a built-in, front-facing, passive RFID tag that uses Ultra High Frequency (UHF) RFID technology
and requires an RFID reader with compatible software. It provides auto-identification capabilities for
asset management and tracking. The RFID tags are compatible with the Generation 2 GS1 EPC Global
Standard and are ISO 18000-6C compliant. They operate in the 860- to 960-MHz UHF band. For more
information, see Radio Frequency Identification (RFID) on Cisco Catalyst 9000 Family Switches.
• Is chassis-specific. (Add = to the model number for spares)
• Model number C9404-FAN for the Catalyst 9404R Switch.
This model has eight individual fans (two rows of four each). It supports a minimum airflow of 640
cubic feet per minute (CFM) at 100 percent fan throttle.
• Model number C9407-FAN for the Catalyst 9407R Switch.
This model has 12 individual fans (three rows). It supports a minimum airflow of 960 cubic feet
per minute (CFM) at 100 percent fan throttle.
• Model number C9410-FAN for the Catalyst 9410R Switch.
This model has 16 individual fans (four rows). It supports a minimum airflow of 1190 CFM at 100
percent fan throttle.
