Product Overview

The Cisco Nexus® 7000 Series AC power supply modules (Figures 1, 2, and 3) deliver fault tolerance, high efficiency, load sharing, and hot-swappable features to the Cisco Nexus 7000 Switches. Each Cisco Nexus 7000 chassis can accommodate multiple power supplies, providing both chassis-level and facility-level power fault tolerance.

The variable output power supplies scale from 1400 to 7500 watts (W) and support multiple system-level redundancy options for greater availability. Designed to address high-availability requirements, the power supplies 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 fitted at the back of the Cisco Nexus 7000 chassis, allowing installation and removal without disturbing the network cabling on the front.

Figure 3. Cisco Nexus 7000 7.5-kW AC Power Supply Module

Cisco Nexus 7000 Series power supplies are more than 90 percent efficient, so less power is wasted as heat, and more power is available for the system to use than with typical power supplies.

Cisco Nexus 7000 3.0-kW AC Power Supply

The 3.0-kilowatt (kW) AC power supply module for the Cisco Nexus 7000 Switches is a single 20-ampere (A) AC input power supply. Connecting to high line nominal voltage (220 VAC) will produce a power output of 3000W. Connecting to low line nominal voltage (110 VAC) will produce a power output of 1400W. Table 1 shows the available power output for the input options.

Cisco Nexus 7000 6.0-kW AC Power Supply

The 6.0-kW AC power supply module for the Cisco Nexus 7000 Switches is a dual 20A AC input power supply. When both inputs are at high line nominal voltage (220 VAC), the power output is 6000W. Connecting to low line nominal voltage (110 VAC) or using just one input will produce lower output power levels. Table 2 shows the available power output for the input options.

Cisco Nexus 7000 7.5-kW AC Power Supply

The 7.5-kW AC power supply module for the Cisco Nexus 7000 Switches is a dual 30A AC input unit. The AC power cords for the 7500W power supply are hard wired directly to the power supply. When both inputs are connected, the output power is 7500W. If less power is required when just one input is connected, the power output is 3750W. Table 3 shows the power output provided by one 7.5-kW AC power supply module. Two versions of the 7.5-kW AC power supply are available: United States and Japan, and International.

Cisco Nexus 7000 Series Power Supply Redundancy

The Cisco Nexus 7000 chassis supports multiple load-sharing, fault-tolerant, and hot-swappable power supplies. As few as just one power supply can be used to operate a switch chassis. Use of multiple power supplies provides additional power capacity and resilience after failure of the power supply, the generating supply itself, or a facility component such as an uninterruptible power supply (UPS) or a circuit breaker.

Cisco Nexus 7000 systems can operate in four user-configurable power-redundancy modes, summarized in Table 4, to meet the redundancy needs of the environment.

Table 4. Power Redundancy Modes

Redundancy Mode

Description

Combined

This mode does not provide redundancy. The power available to the system is the sum of 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 (Only supported with 220V).

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 7000 system depends on the types of power supplies installed, the number of connected inputs, and the configured power supply redundancy mode. Table 5 shows the maximum available power for each redundancy mode for the 3.0-, 6.0-, and 7.5-kW power supplies.

Note: A maximum of four power supplies are supported on the Cisco Nexus 7000 4-Slot Switch, two power supplies are supported on the Cisco Nexus 7000 9-Slot Switch, three power supplies are supported on the Cisco Nexus 7000 10-Slot Switch and four power supplies are supported on the Cisco Nexus 7000 18-Slot Switch. The 3.0-kW power supply can only be used on the Cisco Nexus 7000 4-Slot Switch. Mixed combinations with the 6.0- or 7.5-kW power supplies are not supported.

For the Cisco Nexus 7000 9-Slot, 10-Slot, and 18-Slot Switches, 6.0- or 7.5-kW power supplies can be used. Mixed combinations of the 6.0- and 7.5-kW power supplies are supported. The power redundancy modes are designed to determine the optimum power for the combination of power supplies installed, helping ensure system availability.

The 6.0-kW power supply supports operation with 110 and 220V on either or both of the two inputs, which results in different levels of output power for the different redundancy modes.

Table 6 shows the maximum system output power that can be drawn from two 6.0-kW power supplies in a chassis with different combinations of input voltage and redundancy modes.
