Auxiliary Power Adapter
C9200CX-12T-2X2G switches can be powered either through the 1G copper uplink port connected to a PoE
PSE port capable of providing IEEE 802.3bt Class 6 power or through an auxiliary AC-DC(PWR-ADPT) or
DC-DC(C9K-ADPT-DC) power adapter. If the switch has both PD power and auxiliary power adapter
connected, the auxiliary power takes precedence over PD power and the PD port gets disabled. If both are
connected and the auxiliary power source is removed, the switch resets for the PD to perform detection and
classification before providing power to the system.
You can order the power adapter with the switch, or you can order it later from your Cisco representative.
Power Supply Modules
The switch has a field replaceable main AC power supply module and a redundant hot-swappable field
replaceable AC power supply module. The switch is powered through one or two internal power supply
modules. In switches with PoE capability, the redundant power supply can also be used for extra PoE power.
Following are the power supply modules supported on Cisco Catalyst 9200 Series Switches:
• PWR-C5-125WAC
• PWR-C5-600WAC
• PWR-C5-1KWAC
• PWR-C6-125WAC
• PWR-C6-600WAC
• PWR-C6-1KWAC
The switch has two internal power supply module slots. You can use two AC power supply modules or one
power supply module and a blank module (PWR-C5-BLANK).
The switch can operate with either one or two active power supply modules.
Switch Models, on page 1 shows the default power supply modules that ship with each switch model. All
power supply modules (except the blank modules) have internal fans. All switches ship with a blank power
supply module in the second power supply slot. Each AC power supply module has a power cord
(CAB-TA-XXX) for connection to an AC power outlet.
Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both
power supply module slots must be populated with either a power supply or a blank module.
Caution
The power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The
output voltage range is 12 to 12.5 V for 125W power supply and 54 to 56 V for 600W and 1000W power
supplies.
All the PoE-enabled switches when installed with both the power supplies support full PoE+; 1440W on a
48-port switch and 740W on a 24-port switch. The partial PoE-enabled switches support only 600W power
supply providing a PoE budget of 370W. If the switch is installed with one power supply, the available POE
budget is 370W and 740W, if there are two power supplies installed.
The following tables show the PoE available and PoE requirements for PoE switch models.
