Question 1

What is PWR-C1-1100WAC-P?

Accepted Answer

PWR-C1-1100WAC-P is a Cisco 1100 W AC Platinum certified power supply module for supported Catalyst 9300-family switch power bays. It is an internal hot-plug C1 PSU, not a router, server, cable, adapter, transceiver, firewall, wireless, memory, storage, UPS, or battery product. Selection should start with the exact switch chassis and Cisco power-supply table.

Question 2

Which product category should PWR-C1-1100WAC-P use?

Accepted Answer

PWR-C1-1100WAC-P should be categorized as a switch power supply. The item belongs with internal Catalyst 9300 C1 PSU modules and should not inherit router, transceiver, cable, wireless, adapter, storage, server, memory, firewall, PDU, UPS, battery, or power-injector attributes unless an authoritative manufacturer source specifically identifies that category.

Question 3

Which switch families are listed for PWR-C1-1100WAC-P?

Accepted Answer

Cisco documentation places PWR-C1-1100WAC-P in the Catalyst 9300-family C1 power-supply ecosystem, with support across C9300 Series Switches, C9300L Series Switches, and C9300X Series Switches where the chassis and power plan match. Buyers should still verify the exact switch model, power bay, and software or hardware documentation before purchase.

Question 4

What is the rated output of PWR-C1-1100WAC-P?

Accepted Answer

The documented maximum rated output for PWR-C1-1100WAC-P is 1100 W. Cisco lists the DC output as -56VDC at 19.64A, and the module should be selected only when that wattage class matches the switch model and total power budget. Do not substitute another wattage only because the enclosure family appears similar.

Question 5

What input voltage does PWR-C1-1100WAC-P support?

Accepted Answer

PWR-C1-1100WAC-P uses AC input rated at 115 to 240 VAC, 47 to 63 Hz. Cisco also lists input current as 12-6A. Facility power, circuit capacity, cord type, and local installation practices should be checked before deployment, especially when the module is used in a second bay or in a stack with shared power behavior.

Question 6

What input connector is used on PWR-C1-1100WAC-P?

Accepted Answer

The Cisco table lists IEC 320-C16 as the input receptacle for PWR-C1-1100WAC-P. This detail matters because the matching cord path differs between C1 power-supply wattages. Procurement and field teams should record the receptacle beside the SKU to avoid dispatching an incompatible AC power cord. Record this before shipping.

Question 7

Does PWR-C1-1100WAC-P include a power cord?

Accepted Answer

The power-supply data lists a 15A AC power cord path for PWR-C1-1100WAC-P. Cord inclusion and plug style should be confirmed with the seller, region, and order condition because ecommerce listings sometimes separate PSU modules and localized cords. The core product record should not invent a country-specific cable unless verified for that offer.

Question 8

Is PWR-C1-1100WAC-P hot-swappable?

Accepted Answer

Cisco describes Catalyst 9300 C1 power supplies, including PWR-C1-1100WAC-P, as hot-swappable. Replacement still depends on available system power, StackPower behavior, full PoE load, and slot population. Technicians should follow Cisco service guidance and avoid leaving an opening empty after removing a supply or blank cover.

Question 9

Does PWR-C1-1100WAC-P support redundancy?

Accepted Answer

PWR-C1-1100WAC-P participates in Catalyst 9300 power-bay designs where one or two active modules are used in supported switches. Redundant behavior depends on chassis configuration, total load, and StackPower planning. The module should not be described as universal N+1 equipment outside the switch platform documentation. Use the host switch guide.

Question 10

What LEDs are available on PWR-C1-1100WAC-P?

Accepted Answer

Cisco identifies AC OK and PS OK LEDs on the C1 supply assembly used by PWR-C1-1100WAC-P. These indicators help local technicians check AC input and DC output status after installation or service. LED state should be interpreted with the hardware guide rather than treated as remote monitoring capability.

Question 11

Does PWR-C1-1100WAC-P have remote monitoring?

Accepted Answer

PWR-C1-1100WAC-P itself should not be presented as a standalone remote-monitoring device. It is a power module installed inside supported Catalyst 9300-family switches. Any management visibility comes from the host switch platform and documented system behavior, not from an independent PSU network interface or separate monitoring controller.

Question 12

What cooling method is documented for PWR-C1-1100WAC-P?

Accepted Answer

Cisco notes that Catalyst 9300 C1 power-supply modules have internal fans, and that applies to PWR-C1-1100WAC-P. Cooling statements should stay limited to the module fan and the host switch airflow rules. Slot blanks and installed supplies also matter because open bays affect proper chassis airflow.

Question 13

What are the dimensions of PWR-C1-1100WAC-P?

Accepted Answer

Cisco lists PWR-C1-1100WAC-P at 1.58 inches high, 3.25 inches wide, and 13.7 in deep. These are module dimensions for the supported switch power bay. Shipping box dimensions, pallet size, or rack-space claims should not be added unless a separate verified source provides them. Use separate verified logistics records.

Question 14

How much does PWR-C1-1100WAC-P weigh?

Accepted Answer

The listed module weight for PWR-C1-1100WAC-P is 3.1 lb (1.4 kg). That value should be used as the product hardware weight, not as a shipping weight. If an ecommerce workflow needs packed shipment weight, the value should come from a verified logistics source or seller record.

Question 15

What efficiency level applies to PWR-C1-1100WAC-P?

Accepted Answer

PWR-C1-1100WAC-P is identified as an AC Platinum-certified power supply module. The product record may use 80 Plus Platinum and Platinum-rated language, but it should not invent a percentage efficiency number unless the exact-SKU source provides one. Certification language should match the Cisco naming and tables.

Question 16

How does PWR-C1-1100WAC-P compare with PWR-C1-715WAC-P?

Accepted Answer

PWR-C1-1100WAC-P and PWR-C1-715WAC-P are both Cisco Catalyst 9300 C1 Platinum AC power-supply PIDs, but they target different wattage classes. PWR-C1-1100WAC-P is the 1100 W option, while PWR-C1-715WAC-P is a 715 W option. Selection should follow the switch model, PoE budget, redundancy plan, and Cisco compatibility table.

Question 17

How does PWR-C1-1100WAC-P compare with PWR-C1-350WAC-P?

Accepted Answer

PWR-C1-1100WAC-P and PWR-C1-350WAC-P should not be treated as interchangeable only because both belong to the C1 power-supply family. PWR-C1-1100WAC-P is documented as 1100 W, while PWR-C1-350WAC-P serves a different wattage role. Match the PSU to chassis requirements, endpoint load, and second-bay plan before ordering. Confirm the PID before staging.

Question 18

Is PWR-C1-1100WAC-P the same as a non-Platinum C1 supply?

Accepted Answer

PWR-C1-1100WAC-P should remain separate from similarly named non-Platinum C1 power supplies. The -P suffix identifies the Platinum-certified version in the Cisco power-supply tables. Product content should preserve the full SKU, including suffixes, to avoid mixing different efficiency classes or catalog entries. That separation protects receiving accuracy.

Question 19

Is PWR-C1-1100WAC-P an external adapter?

Accepted Answer

PWR-C1-1100WAC-P is not an external desktop adapter or inline power brick. It is an internal hot-plug power supply module for supported Catalyst 9300-family switch bays.

Question 20

Is PWR-C1-1100WAC-P suitable for routers or servers?

Accepted Answer

PWR-C1-1100WAC-P should not be routed to router or server content. Cisco positions it as a Catalyst 9300-family switch power-supply module. If a router, server, firewall, storage appliance, or wireless platform is involved, the item should be rejected for this category and sent to the correct product prompt.

Question 21

What does the -P suffix mean for PWR-C1-1100WAC-P?

Accepted Answer

For PWR-C1-1100WAC-P, the -P suffix is part of the exact Cisco manufacturer part number and identifies the Platinum-certified AC supply entry. The suffix should never be trimmed from the SKU, because similar C1 power-supply PIDs exist with different wattage or certification characteristics. Preserve it in every spreadsheet cell.

Question 22

What output connector should be listed for PWR-C1-1100WAC-P?

Accepted Answer

The power-supply schema should use N/A for output connectors on PWR-C1-1100WAC-P when no separate customer-facing connector is documented. The module installs into the supported switch power bay and feeds the switch internal power bus, so unsupported external outlet or cable-connector claims should be excluded. Keep outlet fields separate from PSU bays.

Question 23

What protections should be listed for PWR-C1-1100WAC-P?

Accepted Answer

Use N/A for protections on PWR-C1-1100WAC-P unless an exact-SKU source documents named protection features. Generic over-voltage, short-circuit, surge, or thermal-protection claims should not be invented from category assumptions. Specification values should stay tied to Cisco data or another authoritative manufacturer source. This keeps the schema evidence based.

Question 24

What operating temperature applies to PWR-C1-1100WAC-P?

Accepted Answer

Cisco lists Catalyst 9300 power-supply operating conditions at 23 to 113 F, or -5 to 45 C, up to 5000 feet. That range should be used for PWR-C1-1100WAC-P with the same altitude context. Storage temperature or extended operating claims require separate exact-source support. Include the altitude note with the value.

Question 25

What compliance information should be used for PWR-C1-1100WAC-P?

Accepted Answer

Compliance content for PWR-C1-1100WAC-P should remain limited to verified standards from Cisco documentation, such as EMC references where listed.

Keep approvals grouped only when sourced.

Question 26

Does PWR-C1-1100WAC-P provide UPS capacity or battery runtime?

Accepted Answer

PWR-C1-1100WAC-P is not a UPS and does not include a battery runtime specification. The power-supply schema should keep UPS capacity and battery runtime as N/A for this product. Adding backup-time claims would misclassify the part and create unsupported ecommerce content. Keep those UPS fields as N/A.

Question 27

Does PWR-C1-1100WAC-P provide output outlets?

Accepted Answer

PWR-C1-1100WAC-P does not provide external output outlets like a PDU or UPS. It is an internal switch PSU that connects through the Catalyst power bay. The output outlets field should remain N/A unless a manufacturer source documents customer-facing outlets, which is not the case for this module.

Question 28

What product name should be used for PWR-C1-1100WAC-P?

Accepted Answer

The product name should reflect Cisco's documented wording: 1100 W AC Platinum certified power supply module. Ecommerce naming may add brand, Catalyst 9300 family, wattage, AC input, hot-swap form factor, and Platinum certification, but it should not add unsupported PoE budget, lifecycle, warranty, stock, or lead-time claims.

Question 29

What is the best optimized name style for PWR-C1-1100WAC-P?

Accepted Answer

A suitable optimized name for PWR-C1-1100WAC-P identifies Cisco, Catalyst 9300, switch power supply module, 1100 W AC rating, hot-swap design, and 80 Plus Platinum class.

How should refurbished PWR-C1-1100WAC-P units be described?

Accepted Answer

Refurbished PWR-C1-1100WAC-P content should focus on verifiable receiving and functional checks, such as output-voltage and ripple verification under load, fan and thermal review, connector inspection, and latch condition. It should not invent remaining life, original warranty, unused status, or factory-new condition unless the seller record proves it.

Question 31

What should buyers verify before ordering PWR-C1-1100WAC-P?

Accepted Answer

Buyers should confirm the exact Catalyst chassis, power-supply bay type, 1100 W requirement, input voltage, receptacle, cord path, redundancy plan, and StackPower context before ordering PWR-C1-1100WAC-P. This is especially important when several C1 modules appear similar but differ by wattage, efficiency class, or connector requirement.

Question 32

Why should the SKU be preserved exactly for PWR-C1-1100WAC-P?

Accepted Answer

The full string PWR-C1-1100WAC-P identifies a specific Cisco manufacturer part number. Removing suffixes, changing punctuation, or dropping characters risks matching a different C1 power-supply module.
