Description

Cisco Nexus7700-18Slot Chassis Network Switch Ghana

The Cisco Nexus7700-18Slot Ghana is an 18-slot switch with 18 front-accessible module slots and front-to-back airflow with integrated cable management system. It is a high system capacity is designed to meet the scalability requirements of the largest cloud environments. Featuring the latest extension to the Cisco Nexus 7000 Series modular switches Cisco Nexus7700-18Slot Ghana is equipped with more than 83 Terabits per second (Tbps) of overall switching capacity, delivering the highest-capacity 10, 40, and 100 Gigabit Ethernet ports in the industry, with up to 768 native 10-Gbps ports, 384 40-Gbps ports, or 192 100-Gbps ports. This high system capacity is designed to meet the scalability requirements of the largest cloud environments.

The Cisco Nexus7700-18Slot Ghana chassis use a passive mid-plane architecture, providing physical connectors and copper traces for interconnecting the fabric modules and I/O modules for direct data transfer. All inter-module switching is performed via crossbar fabric ASICs on the individual I/O modules and fabric modules. A scalable, fully distributed fabric architecture uses up to six fabric modules to deliver up to 1.32 Tbps per slot of bandwidth in the Cisco Nexus7700-18Slot Ghana on day one. The midplane design on the Cisco Nexus7700-18Slot Ghana supports flexible technology upgrades as your needs change, providing ongoing investment protection. Future fabric modules will allow higher bandwidth capabilities on the platform.

Features

• The Cisco Nexus7700-18Slot Ghana Switch, with up to 16 I/O module slots, supports up to 768 x 1 and 10 Gigabit Ethernet ports, 384 x 40 Gigabit Ethernet ports, and 192 x 100 Gigabit Ethernet ports, to meet the demands of the largest data center deployments.
• The Cisco Nexus 7700 18-Slot Switch has two dedicated half-slot supervisors to provide full redundancy, stateful supervisor switchover, and hitless In-Service Software Upgrade (ISSU) capabilities.
• The Cisco Nexus 7700 18-Slot Switch has six fabric module slots to provide simultaneously active fabric channels to each of the I/O and supervisor modules. Through the parallel forwarding fabric architecture, the Cisco Nexus7700-18Slot Ghana Switch can achieve 42 Tbps of forwarding capacity or more.
• Front-to-back airflow helps ensure that the Cisco Nexus 7700 18-Slot Switch addresses the requirement for hot-aisle and cold-aisle deployments to support efficient cooling.
• The system uses three redundant fan trays for cooling. Each fan tray is composed of independent variable‑speed fans that automatically adjust to the ambient temperature, to reduce power consumption in well-managed facilities while helping to enable optimum operation of the switch. The system also allows hot swapping of fan trays without negatively affecting the system.
• The system supports an optional door and air filter to help ensure clean airflow through the system. The addition of the air filter satisfies NEBS requirements.
• The Cisco Nexus7700-18Slot Ghana Switch can have up to sixteen 3- or 3.5-kW power supplies. The smaller power supply configuration provides more flexibility and greater control in power provisioning. The 16 power supply bays are designed for future growth, and most common configurations do not require the use of all power supply units for redundant power configurations.
• I/O modules, supervisor modules, and power supplies are accessible from the front, and fabric modules and fan trays are accessible from the back of the chassis.

Integrated Cable Management System

An integrated cable management system, custom designed for the Cisco Nexus7700-18Slot Ghana Switch, supports the cabling requirements of a fully configured system at either or both sides of the switch, providing outstanding flexibility. All system components can easily be removed with the cabling in place, providing ease of maintenance with no disruption.

Easy Operation

 A series of LEDs at the top of the Cisco Nexus7700-18Slot Ghana chassis provides a clear summary of the status of the major system components, alerting operators to the need to conduct further investigation. These LEDs report the power supply, fan, fabric, supervisor, and I/O module status.

Energy-Efficient Design

The Cisco Nexus7700-18Slot Ghana uses 3.5-kW and 3-kW power supplies that are 96 and 90 percent efficient or greater, so less power is dissipated as heat, and more power is available for the system to use than with typical power supplies. These high-efficiency power supplies allow smaller power configuration and provide flexible power provisioning.
