Cisco Nexus7000-18Slot Chassis Network Switch Ghana

The Cisco Nexus7000-18Slot Ghana Switch comprise a modular data center-class product line. It is is based on a proven operating system, with enhanced features to deliver real-time system upgrades with exceptional manageability and serviceability. This 7000 series is designed for highly scalable 10 Gigabit Ethernet networks with a fabric architecture that scales beyond 17 terabits per second (Tbps) and that supports high-density 40 and 100 Gigabit Ethernet deployments. 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 18-Slot chassis with up to 16 I/O module slots supports up to 768 x 1 and 10 Gigabit Ethernet ports, 96 x 40 Gigabit Ethernet ports, and 32 x 100 Gigabit Ethernet ports, meeting the demands of the largest data center deployments. It has two dedicated supervisor slots to provide full redundancy. Side-to-side airflow increases the system density in a 25RU footprint, optimizing the use of rack space. The optimized density provides more than 16RU of free space in a standard 42RU rack for cable management and patching systems. Independent variable-speed system and fabric fans provide efficient cooling capacity to the entire system. Fan-tray redundancy features help ensure reliability of the system and support for hot swapping of fan trays. I/O modules and supervisor modules are accessible from the front, and fabric modules, power supplies, and fan trays are accessible from the back.

The Cisco Nexus7000-18Slot Ghana incorporate significant enhancements in design, power, airflow, cooling, and cabling. The Cisco Nexus7000-18Slot Ghana chassis use side-to-side airflow to deliver high density in a compact form factor. 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 operation efficiency. In addition, the Cisco Nexus 7000 Series 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 customers.

Features

Infrastructure scalability for investment protection

• Designed for future scalability to switching capacity of more than 15 terabits per second
• Modular, flexible, scalable Linux-based OS
• Efficient power and cooling design
• Virtualization for efficient resource utilization

Operational continuity

• Lossless, nondisruptive upgrades for zero service downtime
• Graceful system operations to minimize the effect of upgrades and other maintenance tasks
• Comprehensive, open Extensible Markup Language (XML) API for flexible management options

Transport flexibility

• Support for new technologies without total upgrades
• Virtualized control plane and data plane forwarding for optimized performance
• Support for emerging 40 Gbps and 100 Gbps Ethernet standards

Air flow

• Air flows side to side.
• Air enters through the inlet located at the right side of the chassis and exits at the left side the chassis.

Fan modules

2 system fan modules incorporating I/O and fabric fans.

Fan modules removable from the rear

Both fan modules are removable from the rear, and hence there is no obstruction from the I/O cabling on the front. This arrangement enables continuous system operation during maintenance.

Variable fan speeds

• Fans have 256 speed levels controlled by software.
• The fan speed changes based on the I/O module type (and supervisor) and the inlet temperature reading on the supervisor.
• Power consumption and noise emission by fans is optimized.

Self-healing mechanism

The software tracks the temperature of the most critical components of the I/O modules and the supervisors. If the recorded temperature is higher than a system-defined threshold, the fan speed automatically increases and stays at that speed until the temperature falls below the threshold.

Fan redundancy

• Both fan modules incorporate fan and controller redundancy and are hot swappable.
• All the fans are required for normal operation. If the software detects any fan module removal, it warns the user with a syslog message and will shut down the system in 3 minutes unless the removed fan module is replaced. Failure of an individual fan does not result in system shutdown.

Cabling and Cabinet

The cable management system for the Cisco Nexus 18-Slot chassis is located on both sides of the chassis aligned with the module slots. The cable management is designed for high-density Cat6A cabling groomed to either side or both sides.
