The Cisco® Nexus 7000 Series Switches comprise a modular data center-class product line designed for highly scalable 10 Gigabit Ethernet networks with a fabric architecture that scales beyond 15 terabits per second (Tbps). Designed to meet the requirements of the most mission-critical data centers, it delivers continuous system operation and virtualized, pervasive services. The Cisco Nexus 7000 Series is based on a proven operating system, with enhanced features to deliver ereal-time system upgrades with exceptional manageability and serviceability. Its innovative design is purpose built to support end-to-end data center connectivity, consolidating IP, storage, and interprocess communication (IPC) networks onto a single Ethernet fabric.
The Cisco Nexus 7000 6.0KW AC Power Supply Module (Figure 1) is the first of the Cisco Nexus 7000 Series power supplies. Each Cisco Nexus 7000 Series 10 Slot chassis can hold up to three load-sharing, fault-tolerant, and hot-swappable power supplies. The power supplies are at the back of the chassis, allowing installation and removal without obstruction by the cables on the front.

The Cisco Nexus 7000 6.0KW AC Power Supply Module is a dual 20-ampere (A) AC input unit. Power supply output depends on a combination of the number of inputs, the AC voltage, and the configured power redundancy mode. Table 1 shows the power output provided by one Cisco Nexus 7000 6.0KW AC Power Supply Module for various inputs.

Cisco Nexus 7000 Series systems can operate in four user-configurable power-redundancy modes, summarized in Table 2.
Table 2. Power Redundancy Modes
Redundancy Mode
Description
Combined
No redundancy; power available to the system is the sum of power outputs of all power supplies in the chassis
Power supply redundancy (N+1)
Guards against failure of one of the power supplies; power available to the system is the sum of the two least-rated power supplies
Input source redundancy
(grid redundancy)
Guards against failure of one input circuit (grid); for grid redundancy, each input on the power supply is connected to an independent AC feed, and power available to the system is the minimum power from either of the input sources (grids)
Power supply and input source redundancy
(full redundancy)
System default redundancy mode; guards against failure of either one power supply or one AC grid, and power available is always the minimum of input source and power supply redundancy
Table 3 shows the maximum system output power that can be drawn from three power supplies in a chassis with different combinations of inputs and redundancy modes.

Features and Benefits
Table 4 summarizes the features and benefits of the Cisco Nexus 7000 6.0KW AC Power Supply Module.
Table 4. Features and Benefits
Feature
Benefit
Multiple inputs
Provide redundancy within the power supply unit; if one input fails, power is still drawn from the other input
Universal input (110 to 240 VAC, 50 to 60 hertz [Hz])
• Flexibility to provision circuits with either high-input voltage (200-240V) or low-input voltage (100-120V) depending on availability and power output needs.
• Capability to connect one input with a 220V line and the other with a 110V line
Compatible with future Cisco Nexus 7000 Series chassis
Provides investment protection
Hot swappable
Enables continuous system operations; no downtime when replacing power supply (assuming that the remaining power supplies can provide enough power to support the system)
Temperature sensor and instrumentation
Measures internal temperature and shuts down the power supply if temperature exceeds thresholds; prevents damage due to overheating of power supply unit
Internal fault monitoring
Detects short circuits and component failures within the power supply unit; if a failure is found, the unit is shut down
Intelligent remote management
Users can remotely power cycle one or all power supplies using the supervisor command-line interface (CLI), enabling remote management and improving operational efficiency (not available at initial software release)
Real-time power draw
Shows real-time actual power consumption (not available at initial software release)
Variable fan speed
Allows reduction in fan speed for lower power usage in well-controlled environments while helping ensure sufficient system cooling capacity
