Product Overview
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 real-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 Series 10-Slot chassis (Figure 1) incorporates significant enhancements in chassis design, power, airflow, cooling, and cabling. The chassis has front-to-back airflow, making it a good solution in hot aisle and cold aisle deployments. The power supplies, fan trays, and fabrics can be replaced from the back of the chassis without any obstruction from the I/O cables, thereby enabling operational efficiency. In addition, the Cisco Nexus 7000 Series 10-Slot chassis has many power-saving enhancements such as temperature sensors, variable-speed fans, and high-efficiency power supplies that reduce the total cost of ownership (TCO) for the customers.

Physical Specifications
The Cisco Nexus 7000 Series 10-Slot chassis has two supervisor slots, eight I/O module slots, a cable management door, and an optional air filter on the front of the chassis. On the back, it has five fabric slots, three power supply bays, two system fan trays, and two fabric fan trays. Table 1 summarizes the physical features of the chassis.

Power
The Cisco Nexus 7000 Series 10-Slot chassis has three power supply bays that can hold the same number of power supplies. The 6000W power supply is the first of the Cisco Nexus 7000 Series power supplies. Each 6000 watt (W) power supply has two universal (100-240 volt [V]) inputs that can be connected to two AC sources.
Table 2 shows the power output provided by one Cisco Nexus 7000 6.0KW AC Power Supply Module for various inputs.

The power supplies are hot swappable, enabling continuous system operation. They also incorporate advanced features such as internal fault monitoring, temperature sensing, real-time power draw statistics, and variable-speed fans.
The Cisco Nexus 7000 Series systems can operate in four user-configurable power redundancy modes as shown in Table 3.
Table 3. Power Redundancy Modes
The platform software requires a minimum of 3284W of power to activate the system. If the power available from the power supplies is more than 3284W, the additional power is used to activate the I/O modules. If there is not enough power to activate the line cards, the line cards are kept in a power-denied state. After more power is provisioned, the user has to power-on the line cards manually to activate them.
Climatic Environment
Table 4 summarizes the climatic environment for the Cisco Nexus 7000 Series 10-Slot chassis.

Airflow and Cooling
The chassis cooling system consists of two system fan trays that deliver cooling for the I/O and supervisor modules and two fabric fan trays that cool the fabric modules. Each system fan tray is composed of multiple independent fans. All fan trays are removable from the rear of the chassis, allowing continuous system operation during maintenance. Table 5 summarizes the airflow and cooling features of the Cisco Nexus 7000 Series 10-Slot chassis.

Acoustics
The noise level of the Cisco Nexus 7000 Series 10-Slot chassis without an air filter is within 3 dBA of the NEBS requirement (GR-63-Core, R4-96: Declared sound power level for equipment to be located in attended telecommunication room is 78 dBA).
The measured declared sound power levels for the Cisco Nexus 7000 Series 10-Slot chassis are 78.9 dBA when there is no filter and 81.7 dBA with a filter. The sound pressure levels are 67.2 dBA without a filter and 70.2 dBA with a filter. (The measured sound power levels are 75.9 dBA without an air filter and 78.7 dBA with an air filter. As required by NEBS, 3 dBA is added to the measured sound power levels to approximate statistical upper-limit values.)
A fan speed detection and control minimizes noise and maintains reliability while still maintaining system temperature within operating parameters.
Cabling and Cabinet
The cable management system for the Cisco Nexus 7000 Series 10-Slot chassis is located on the front of the chassis above the modules. In the largest configuration, it is capable of handling 384 CAT 6A copper cables plus 8 management port cables. All cables can be groomed either to one side of the chassis or to the left and right. A top-hinged door covers the cable management system. The cable management system can be removed to enable alternative ways of managing the cables.
The Cisco Nexus 7000 Series 10-Slot chassis should be installed in either a standard four-post rack or a four-post cabinet. Panduit and Chatsworth Products (CPI) offer cabinets verified by Cisco that fit up to two Cisco Nexus 7000 Series 10-Slot chassis in a 45RU height.
Regulatory Compliance
The Cisco Nexus 7000 Series 10-Slot chassis is designed to meet regulator emissions and immunity requirements when tested with existing and future cards and power supplies as summarized in Table 6.
Table 6. Emissions and Immunity Specifications
The Cisco Nexus 7000 Series 10-Slot chassis does not meet GR-1089 issue 4 and service providers' acoustic specifications. Its sound is within 3 dBA of NEBS criteria when operated without a filter. Table 7 summarizes NEBS compliance.
