Overview
The CISCO N7K-DC-3KW is a specialized power supply module designed to cater to the needs of data center environments, specifically engineered for Cisco Nexus 7000 Series Switches. This power supply offers a scalable power output ranging from 1500 W to 3000 W, ensuring that it can adequately support the varying power demands of network infrastructure. Its primary focus is on delivering efficient power management and reliability for critical network operations.
With a power rating of 3.0 KW and the capability to operate in both DC environments and mixed DC and AC operations, the CISCO N7K-DC-3KW stands out for its versatility. It supports hot swapping, allowing for maintenance or upgrades without interrupting network services. The absence of an integrated locking latch simplifies the installation process, though it requires a tightening torque between 15 in. per lb (minimum) and 40 in. per lb (maximum) to ensure secure connections.
This power supply module does not come with a power cable, allowing network administrators to select cables that best fit their specific requirements. It features two inputs for connectivity, with each isolated input stage providing a -48 VDC connection in North America and a -60 VDC nominal at 30 A in other regions. The DC input current is rated at 40A for each DC input at -48 VDC input voltage, emphasizing its capacity to handle high power demands.
Efficiency is a key attribute of the CISCO N7K-DC-3KW, with an operational efficiency of more than 91%. This high efficiency rate contributes to reduced operational costs and a lesser environmental impact, making it a considerate choice for eco-conscious enterprises.
- Software compatibility with Cisco® NX-OS Software Release 6.1.2 or later ensures seamless integration and reliable performance within the Cisco ecosystem.
- Output holdup times of 8 ms for half load and 4 ms for full load guarantee stable power delivery during short interruptions, minimizing the risk of system shutdowns or failures.
- Designed to operate within a wide range of temperatures, from 0 °C to 40 °C, and humidity levels from 10% to 90% (noncondensing), the CISCO N7K-DC-3KW is built to withstand challenging operating conditions.
