Cisco Nexus 7710 - Bundle - Switch - L3 - Managed - Rack-mountable - Refurbished - With 2 X Cisco Nexus 7000 Series Supervisor 2 Enhanced Module, 6x Cisco Nexus 7000 Series Fabric-2 Module - N77C7710B26S2ER-RF

• High availability
  Two supervisor modules operate in active and standby modes with stateful supervisor failover to enhance total system availability.
• Resilient dedicated connectivity to each fabric and I/O module slot
  Dual redundant Ethernet out-of-band channels to each module and fabric provide resilience for communication between the control plane and line-card processors.
• Centralized arbiter
  Active-active control of the flow of traffic through the switch fabric helps ensure transparent switchover with no data loss.
• Virtual output queue (VOQ)
  A quality-of-service (QoS)-aware lossless fabric avoids the problems associated with head-of-line blocking.
• Embedded packet analyzer
  An advanced integrated troubleshooting tool reduces the need for dedicated protocol analyzers and provides faster resolution of control-plane problems.
• Front-panel LEDs
  LEDs provide visible indicators of the supervisor ID, active or standby status, power management, and activity on the compact flash drive.
• Identification LED
  Using the beacon feature, the administrator can clearly identify the chassis and supervisor module.
• USB ports
  Ports enable access to USB flash memory devices for software image loading and recovery.

The Cisco Nexus 7710 chassis has 10 slots for two supervisor modules and up to eight I/O modules. The chassis also holds up to six fabric modules, up to eight AC or DC 3-kW power supplies, and three fan trays. To group the many networking cables for each I/O module on this chassis, you can install cable management frames on either side of the chassis. You can install an optional locking front door and you can install an optional set of air filters on the front door and cable management frames. The following figure shows the standard hardware features seen from the front of the chassis.
