Application Scenarios
Use C9400-PWR-2100AC for Catalyst 9400 maintenance inventory when installed systems already use the 2100W AC power-supply family and the replacement must preserve the same PSU capacity.
Select this SKU only after checking the site feed because the available output changes from 950W on 100-120 VAC to 2112W on 200-240 VAC.
Keep C9400-PWR-2100AC separate from the 3200W AC, 3200W Titanium AC, and 3200W DC supplies when the BOM depends on a specific power class or input-power design.

- In a C9400-PWR-2100AC vs C9400-PWR-3200AC comparison, the main difference is AC output capacity: C9400-PWR-2100AC is the 950W low-line and 2112W high-line option, while C9400-PWR-3200AC is the 1570W low-line and 3200W high-line option.
- The C9400-PWR-2100AC difference from C9400-PWR-3200ACT is both power class and PSU identity, because C9400-PWR-3200ACT is the Titanium-rated 3200W AC module with a 19.87 CFM minimum airflow value.
- For a C9400-PWR-2100AC vs C9400-PWR-3200DC comparison, the key order check is input power: the current SKU uses AC input and a C19 cord path, while C9400-PWR-3200DC is the DC plant power-supply option.
- Which model to choose should follow the installed Catalyst 9400 PSU family, site input power, low-line or high-line output target, and redundant or combined power mode shown in the comparison table.
Selection Guide
1. Use the 2100W AC line for matched PSU bays
Choose C9400-PWR-2100AC when the Catalyst 9400 chassis power plan or replacement stock calls for the 2100W AC supply rather than a 3200W module.
2. Verify the input-voltage class first
Check whether the site uses 100-120 VAC or 200-240 VAC because this SKU changes from 950W total output on low-line input to 2112W on high-line input.
3. Move to the 3200W AC family when the output tier changes
Select C9400-PWR-3200AC or C9400-PWR-3200ACT only when the BOM requires the 3200W AC class; do not treat the 2100W and 3200W supplies as equal capacity spares.
4. Keep DC plant designs on the DC PSU
Use C9400-PWR-3200DC for Catalyst 9400 DC input power designs, because C9400-PWR-2100AC is an AC-input module with a regional C19 power-cord requirement.
PoE Power Planning
|
Planning Item |
Cisco-Confirmed Value |
Procurement Impact |
|---|---|---|
|
Low-line AC output |
940W at 55 VDC plus 10W standby output at 115 VAC |
Sets the lower chassis power budget when the site feed is 100-120 VAC |
|
High-line AC output |
2102W at 55 VDC plus 10W standby output at 230 VAC |
Supports the higher 2112W total output class for 200-240 VAC racks |
|
N+1 redundant mode formula |
2102W x (N-1) plus 10W standby at 230 VAC; 940W x (N-1) plus 10W standby at 115 VAC |
Determines how many supplies remain available after reserving one module for redundancy |
|
Combined mode formula |
2102W x N plus 10W standby at 230 VAC; 940W x N plus 10W standby at 115 VAC |
Shows the combined power pool when the design is not reserving an equivalent standby module |
|
Power budget validation |
Cisco directs users to calculate or estimate system power budget and PoE requirements with Cisco Power Calculator |
Prevents PSU quantity from being approved without checking supervisors, line cards, and PoE load |

|
Regional power cord |
IEC60320/C19 appliance connector and correct regional cord option |
Avoids a cord mismatch between the PSU and facility power |
|
Power-supply mode |
Combined mode, N+1 redundancy, or N+N redundancy |
Determines active and standby PSU placement for the Catalyst 9400 chassis |
