| Product Description |
Cisco PWR-3750-1100AC (C3KX-PWR-1100WAC) Full English Description
Product Overview
Cisco PWR-3750-1100AC, official part numberC3KX-PWR-1100WAC, is a hot-swappable 1100W AC power supply module designed exclusively for Cisco Catalyst 3750-X and Catalyst 3560-X series enterprise switches. It delivers power for base switch operation and high-capacity IEEE 802.3at PoE+ loads, supporting high-density PoE terminals including Wi-Fi access points, IP surveillance cameras and high-power IP phones. This power module supports redundancy and Cisco StackPower technology, ideal for stacked access layer networks with heavy PoE power demands.
Key Features
-
1100W Maximum Total Output Capacity
Rated for 1100W power delivery with -56VDC output, offering abundant power budget for full PoE+ deployments. When two power supplies are installed inside one switch, power redundancy and dynamic load sharing can be realized to avoid service outages caused by single power unit failure. It works seamlessly with StackPower to aggregate and distribute power resources across a switch stack.
-
Autoranging AC Input Specification
-
Input Voltage: 115 VAC ~ 240 VAC
-
Operating Frequency: 50 Hz / 60 Hz
-
Input Connector: IEC C16 power inlet
-
Hot-Swap Modular Architecture
Supports online insertion and removal. Technicians can replace defective power supplies without powering off the switch chassis, minimizing network downtime during routine maintenance.
-
Real-Time LED Status Indication
Front panel equipped withAC OKandPS OKLED indicators, providing instant visual feedback of AC input status and operational health of the power supply.
-
Multi-Level Hardware Protection
Built-in overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short-circuit protection to protect both the power module and host switch hardware.
-
Cisco StackPower Compatibility
Enables power resource pooling among stacked Catalyst 3750-X switches. Available power can be dynamically allocated between stack members to maximize PoE resource utilization.
Supported Hardware Platforms
Cisco Catalyst 3750-X Series, Catalyst 3560-X Series Gigabit Ethernet switches.
Compatible high-power PoE models: WS-C3750X-48PF, WS-C3560X-48PF and other PoE-capable variants.
Typical Application Scenarios
-
Enterprise campus stacked access layer switching
-
Large-scale office, education, healthcare and hospitality networks with mass PoE+ devices
-
High-density PoE Gigabit access deployments requiring power redundancy
-
Network stacks utilizing Cisco StackPower power sharing technology
Technical Specifications
-
Form Factor: Internal pluggable field-replaceable power supply
-
Cooling: Integrated built-in variable speed cooling fan
-
Safety & EMC Certification: UL60950-1, EN60950-1, FCC Class A, CE certified
-
MTBF: 392,174 hours under standard indoor operating environment
