PWR-C1-1100WAC-P Description
PWR-C1-1100WAC-P is a Cisco Catalyst 9300 Series 1100W AC Platinum power supply module for Catalyst 9300, Catalyst 9300L, and Catalyst 9300X switch power-supply bays. It provides 1100W maximum output power with 115 to 240 VAC autoranging input, a -56V at 19.64A output rating, and Platinum efficiency for switch deployments that need more power headroom than lower-wattage Catalyst 9300 power modules. The module supports the redundant internal power-supply design used by these Catalyst 9300 platforms, is hot-swappable when the remaining power budget is sufficient, and should not be treated as a C9300LM, C9300-M, or Meraki MS390 power supply option.

Application Scenarios
PWR-C1-1100WAC-P fits service stock for Catalyst 9300, Catalyst 9300L, or Catalyst 9300X deployments that require the C1 1100W AC Platinum power module listed in Cisco power-supply tables.
Access-switch BOMs that move beyond the 715W AC power class can use this SKU when Cisco’s PoE requirement tables call for one or two 1100W AC Platinum supplies.
Warehouses that support both Catalyst 9300 and Catalyst 9300LM switches should keep PWR-C1-1100WAC-P out of C9300LM replacements, where Cisco lists C6 power supplies instead of the C1 family.

- In a PWR-C1-1100WAC-P vs PWR-C1-1100WAC comparison, the output class is the same 1100W AC range, but the current SKU is the Platinum certified variant used across Catalyst 9300, 9300L, and 9300X power tables.
- The PWR-C1-1100WAC-P difference from PWR-C1-715WAC-P is wattage class: both are Platinum AC supplies, but the current SKU provides 1100W while PWR-C1-715WAC-P provides 715W.
- For a PWR-C1-1100WAC-P vs PWR-C1-1900WAC-P comparison, the key order check is the power plan and input-voltage design because the 1900W module has a higher output class tied to its 230V or 115V operating condition.
- Buyers comparing which model to choose should start with the installed Catalyst family, required PoE budget, C9300LM exclusion, and facility AC voltage before adding the power line to the order line.
Selection Guide
1. Match the C1 bay and Catalyst family
Choose PWR-C1-1100WAC-P when the installed switch is in the Catalyst 9300, Catalyst 9300L, or Catalyst 9300X family and the BOM needs a C1 1100W AC Platinum supply.
2. Keep C9300LM on C6 power supplies
Move away from this SKU for C9300LM replacements because Cisco states that C9300LM switches use C6 supplies and cannot use the other listed PWR-C1 supplies.
3. Separate 715W and 1900W power classes
Select PWR-C1-715WAC-P when the documented requirement is the lower 715W Platinum AC class, or move to PWR-C1-1900WAC-P only when the Catalyst 9300 power plan and input voltage support that higher class.
4. Verify the Meraki-option suffix
Keep PWR-C1-1100WAC-P separate from PWR-C1-1100WAC-P-M when receiving Meraki-option hardware, because Cisco identifies the -M PSU for C9300-M rather than the standard Catalyst 9300 order path.
PoE Power Planning
|
Planning Item |
Cisco-Confirmed Fact |
Quote Check |
|---|---|---|
|
48-port C9300L PoE all-port requirement |
Cisco lists 1 x PWR-C1-1100WAC-P or 2 x PWR-C1-715WAC-P for PoE on all ports |
Add the 1100W supply when the 48-port C9300L power plan needs all-port PoE headroom |
|
48-port C9300L PoE+ all-port requirement |
Cisco lists 2 x PWR-C1-1100WAC-P or 1 x PWR-C1-1100WAC-P plus 1 x PWR-C1-715WAC-P or PWR-C1-715WDC |
Confirm the second PSU line before assuming all-port 30W PoE+ |
|
Catalyst 9300 dual supply design |
Catalyst 9300 switches support dual redundant power supplies and a second supply can be added later |
Treat the secondary PSU as a separate power and redundancy decision |
|
Slot population rule |
The empty power-supply slot must be covered with a blank module |
Keep the cooling requirement visible when only one PSU ships or one PSU is replaced |
|
StackPower environment |
Catalyst 9300 power supplies can be mixed in a stack power design |
Check the actual power-sharing or redundancy mode before removing or downsizing a PSU |
Ordering Checklist

What to Confirm |
Why It Matters |
|---|---|---|
|
Exact PID |
PWR-C1-1100WAC-P |
Prevents substitution with PWR-C1-1100WAC, PWR-C1-1100WAC-P-M, or a different wattage class |
|
Switch family |
Catalyst 9300, Catalyst 9300L, or Catalyst 9300X |
Keeps the spare aligned with Cisco’s supported C1 power-supply tables |
|
AC input |
115 to 240 VAC autoranging, 50 to 60 Hz |
Ensures the site power feed matches the 1100W AC Platinum supply |
|
PoE power plan |
Single or dual PWR-C1-1100WAC-P requirement for the target switch model |
Prevents all-port PoE or PoE+ assumptions from being separated from the installed PSU count |
|
Second bay contents |
A second PSU or blank module in the unused slot |
Maintains the cooling and slot-population requirement documented by Cisco |
