Which Catalyst switches does PWR-C1-1900WAC-P fit?

PWR-C1-1900WAC-P fits the internal power-supply bays of Catalyst 9300, 9300L and 9300X switches. Cisco lists it as an upgrade option for C9300X-48HXN-A and C9300X-48HXN-E, C9300X-24HX-A and C9300X-24HX-E, C9300-48H-A and C9300-48H-E and C9300-24H-A and C9300-24H-E. C9300LM switches do not use any PWR-C1 supply and take PWR-C6 supplies.

How much PoE does PWR-C1-1900WAC-P give when it is the primary supply in place of the default PWR-C1-1100WAC-P in the Catalyst 9300 data sheet power table?

On the data sheet row whose default is PWR-C1-1100WAC-P, fitting PWR-C1-1900WAC-P as the primary supply gives 1390W of available PoE on its own. A second 1900W supply raises it to 3290W. The default supply on the same row gives 590W alone, rising to 2490W with a second 1900W supply.

Which AC power cord does PWR-C1-1900WAC-P need?

Order the cord from the dedicated PWR-C1-1900WAC-P table in the Catalyst 9300 hardware installation guide. The general CAB-TA series is mostly rated 250 VAC, 10A and 2.5 m, but the 1900W supply has its own cord table. Check the country cord against that table before the order is placed.

How far does PWR-C1-1900WAC-P extend from the switch rear panel once installed?

The 1900W module extends 1.5 in. from the switch rear panel. Allow for that extra depth in shallow racks and rear cable management. The supply is hot-swappable, but only when the remaining power budget supports the connected load, and the AC OK and PS OK LEDs show input and output status.

What do the AC OK and PS OK LEDs on PWR-C1-1900WAC-P tell an installer?

The AC OK LED shows that AC input is present and the PS OK LED shows that the output is good. Check both after seating the module. Hot-swap a PWR-C1-1900WAC-P only when the remaining supply can carry the full PoE load, otherwise powered devices can drop during the replacement.

PWR-C1-1900WAC-P Description

The PWR-C1-1900WAC-P is a Cisco Catalyst 9300 Series 1900W AC Platinum power supply for the internal power-supply bays of Catalyst 9300, 9300L and 9300X switches. The supply delivers 1900W from a 200 to 240 VAC input and 1500W from a 115 to 127 VAC input, with a -56V output rating of 33.92A and 26.78A respectively. PWR-C1 supplies are not used with C9300LM switches, which take PWR-C6 supplies.

Application Scenarios

High-Output UPOE Access Closet

A Catalyst 9300 access switch that feeds UPOE and PoE+ endpoints at high port density takes the 1900W supply when the power tables call for a larger PoE budget than 1100W allows.

Closets On 115 V Or 230 V

Because the module delivers 1500W on a 115 to 127 VAC feed and 1900W on a 200 to 240 VAC feed, the same supply serves closets wired to either voltage, with a different PoE ceiling at each.

PWR-C1-1900WAC-P is the highest-output supply in this group, delivering 1900W on a 200 to 240 VAC feed but 1500W on 115 to 127 VAC, while PWR-C1-1100WAC-P tops out at 1100W on 115 to 240 VAC. A 115V-only site still gains 400W over PWR-C1-1100WAC-P. PoE budgets that fit within 1100W stay on PWR-C1-1100WAC-P, within 715W on PWR-C1-715WAC-P, and data-only switches use PWR-C1-350WAC-P at 350W. None of the C1 supplies fit a C9300LM, which takes PWR-C6 supplies.

PoE Power Planning

Planning Item	Cisco-Confirmed Fact	Quote Check
High-output module condition	PWR-C1-1900WAC-P provides 1900W at 230V nominal input and 1500W at 115V nominal input	Match the AC feed before using a 1900W power budget in the BOM
UPOE+ model examples	Cisco lists PWR-C1-1900WAC-P as an upgrade option for C9300X-48HXN, C9300X-24HX, C9300-48H, and C9300-24H power tables	Confirm the exact switch model before adding the 1900W line
Dual-supply chassis design	Catalyst 9300 switches support one or two active internal power supplies and can use a blank cover when one PSU is ordered	Plan the second slot as either a second PSU or the required blank cover
Hot-swap risk	Removing a PSU can interrupt powered devices if the remaining budget does not support the load	Check StackPower mode and available power before field replacement
C9300LM exclusion	Cisco says PWR-C6 power supplies are only for C9300LM and the other PWR-C1 supplies cannot be used with C9300LM	Keep C9300LM service stock on PWR-C6 parts

Ordering Checklist

Catalyst 9300 and 9300X hosts: Order PWR-C1-1900WAC-P as the upgrade for the primary or second supply on C9300-24H, C9300-48H and C9300X-48HX. The PoE tables raise the budget on these models only with this supply.
Unsupported hosts: Do not order for C9300LM switches, which use PWR-C6-600WAC or PWR-C6-1KWAC. No PWR-C1 supply can be used in a C9300LM.
