Cisco Nexus 7700 Platform 3.5-kW High-Voltage Power Supply Modules Data Sheet
Available Languages
Product Overview
The Cisco Nexus® 7700 platform 3.5-kW high-voltage (HV) power supply module (Figure 1) delivers high efficiency, fault tolerance, load sharing, and hot-swappable features to Cisco Nexus 7700 platform switches. The Cisco Nexus 7700 platform chassis can accommodate multiple power supply modules, providing both chassis-level and facility‑level power fault redundancy.
The Cisco Nexus 7700 platform HV power supply modules are universal and versatile power supplies as a single module can support a wide range of AC and DC inputs (100 to 277 VAC and 200 to 380 VDC). Designed to address high-availability requirements, the power supplies provide multiple system-level redundancy options and incorporate internal component-level monitoring, temperature sensors, and intelligent remote-management capabilities. The power supply modules are fully hot swappable, helping ensure no system interruption during installation or upgrades, and they are accessible from the front for easy insertion and removal.
The Cisco Nexus 7700 platform power supplies are 80 Plus Titanium certified with up to 96 percent efficiency, so that less power is wasted as heat, and more power is available for the system to use than with previous-generation power supplies and other typical power supplies. The power supply modules can deliver up to 3500 watts (W) of output power at high-voltage AC and DC (HVAC/HVDC) inputs. Table 1 summarizes the maximum output power levels at various input voltage ranges.

Cisco Nexus 7700 Platform Power Supply Redundancy
The Cisco Nexus 7700 platform chassis supports multiple load sharing, fault tolerance, and various modes of power redundancy to help ensure high availability and optimal operation of the Cisco Nexus 7700 platform switches. As few as one power supply can be used to operate a switch chassis. Use of multiple power supplies provides additional power capacity and redundancy to maintain system power after a failure of a power supply, the power supply generator, or a facility component such as an uninterruptible power supply (UPS) or a circuit breaker.
Cisco Nexus 7700 platform systems can operate in four user-configurable power-redundancy modes, summarized in Table 2, to meet the redundancy needs of the environment.
Table 2. Power Redundancy Modes
| Redundancy Mode |
Description |
| Combined |
This mode does not provide redundancy. The power available to the system is the sum of the power outputs of all power supplies in the chassis. |
| Power supply redundancy (N+1) |
This mode guards against failure of one of the power supplies. The redundant power available to the system is the sum of all power outputs less one of the maximum-rated power supplies. |
| Input source redundancy (grid redundancy) |
This mode guards against failure of one power supply or input circuit (grid). The power available to the system is the minimum power from both grids. If one of the power supplies fails, the operational power redundancy mode changes to the combined mode |
| Power supply and input source redundancy (full redundancy) |
This mode guards against the failure of one power supply or one grid. The power available is the minimum power from the input source and power supply redundancy. If one of the power supplies fails, the operational power redundancy mode changes to the power supply redundancy (N+1) mode. |
The total amount of power available to the Cisco Nexus 7700 platform switch depends on the type of power supplies installed and the configured power supply redundancy mode. The 3.5-kW HV power supply supports low-line and high-line AC and DC inputs, which results in different levels of output power for the different redundancy modes. The 3.5-kW HV power supplies can co-exist with 3.0-kW power supplies in the Cisco Nexus switches and operate transparently while sharing current at a slightly higher level proportional to the output power available from the voltage range in Table 1.
Features and Benefits
Table 3 summarizes the features and benefits of the Cisco Nexus 7700 platform 3.5-kW HV power supply modules.
Table 3. Features and Benefits
| Feature |
Benefit |
| Universal input: 100 to 277 VAC and 50 to 60 hertz (Hz) or 200 to 380 VDC |
Provides the flexibility to provision circuits with either low-voltage (120 VAC) or high-voltage (220, 240, or 277 VAC) AC inputs or high-voltage (200 or 380 VDC) DC inputs, depending on availability and power output needs |
| Energy efficient |
Offers 90 to 96% efficiency to reduce power waste even at low loads achieved with 80 Plus Titanium certification for 3.5-kW (for more information, go to http://www.80plus.org) |
| Compatible with Cisco Nexus 7700 Switches |
Supports low- and high-voltage AC or high-voltage DC inputs, and the compact size provides different levels of power redundancy for Cisco Nexus 7700 Switches |
| Hot swappable |
Enables continuous system operation, with no downtime when replacing the power supply (assuming that the remaining power supplies can provide enough power to support the system) |
| Temperature sensors and instrumentation |
Measures internal temperature and shuts down the power supply if the temperature exceeds the threshold; prevents damage due to overheating of the 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 |
Allows users to remotely power-cycle one or all power supplies using the supervisor command-line interface (CLI), enabling remote management and improving operating 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 use and lower audible noise in well-controlled environments while helping ensure sufficient system cooling capacity |
