Cisco Part Number: C9K-ADPT-DC is a DC-DC power adapter for the C9200CX-12T-2X2G compact switch (80W)
Auxiliary Power Adapter
The C9200CX-12T-2X2G switches can be powered either through the 1G copper uplink port connected to a PoE PSE port supporting IEEE 802.3bt Class 6 power or via an auxiliary AC-DC (PWR-ADPT) or DC-DC (C9K-ADPT-DC) power adapter. When both PD power and auxiliary power are connected, the auxiliary power takes priority, disabling the PD port. If the auxiliary power source is removed, the switch resets to allow PD detection and classification before resuming power. The power adapter is available for order with the switch or separately from your Cisco representative.
