Cisco Catalyst 9400 Series User Manual

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-MHz to 960-MHz UHF band. For more information, see
