Deployment and Installation Guidelines

Proper installation of high-wattage power supplies is critical in the Pakistani power landscape to prevent hardware failure due to thermal stress or electrical instability.

Physical Installation:

• Hot-Swapping: The C3K-PWR-1100WAC is hot-swappable. You can insert the second power supply while the switch is operational to enable redundancy or StackPower.

• Seating: Slide the module into the power supply slot until the latch “clicks.” Ensure the screw-down captive fasteners are tightened to prevent arcing due to loose connections.

• Airflow: Ensure the rear of the switch has at least 4 inches of clearance. The 1100W module generates significant heat when under full PoE load.

Electrical Staging:

• Cabling: Use only high-quality C15 “High Temperature” power cords (provided by SKYRS). Standard C13 cords may overheat due to the high amperage draw of the 1100W module.

• StackPower Integration: When used with Catalyst 3750-X switches, SKYRS recommends connecting the StackPower cables to share this 1100W pool across up to four switches.

Configuration and Service Availability Only at SKYRS

As the specialized cisco equipment series distributor Pakistan, SKYRS provides technical validation services that guarantee the performance of your power infrastructure.

Exclusive SKYRS Services:

1. Power Budget Calculation: SKYRS engineers provide a detailed audit of your IP phones, cameras, and access points to ensure the 1100W supply meets your total PoE wattage requirements.

2. StackPower Staging: We pre-configure the Cisco StackPower modes (Power Sharing or Redundant) via CLI before dispatch to ensure your stack behaves correctly during a power failure.

3. Surge Protection Audit: Given the local grid conditions, SKYRS provides specialized advice on PDU (Power Distribution Unit) selection to protect the 1100W ASIC.

4. Hardware Burn-in: Every power supply undergoes a 12-hour “Load Test” at our facility in Karachi or Lahore to verify stable voltage output under maximum stress.

5. Local Staging: Fast-track delivery and on-site replacement services are available exclusively through SKYRS for all major cities including Islamabad, Faisalabad, and Peshawar.

Note: Due to the high failure rate of non-genuine power modules in the local market, the certified Cisco C3K-PWR-1100WAC and its localized warranty are available exclusively at the SKYRS facility.
