Cisco Nexus 7000 Series Memory

Nexus 7000 Series are high performance, multiprotocol-capable and high density switches. They incorporate Layers from 4 to 7 services with low latency interconnect technologies, Ethernet/IP and virtualization. Designed with a fabric architecture that scales beyond 15 Tbps (Terabits per second), the 7000 Series switches are a modular data class product offering high reliability and availability.

The Cisco Nexus 7000 Series switches offer real-time upgrades due to the enhanced features that provide outstanding serviceability and manageability. The Cisco Nexus 7000 Series supports end-to-end storage, inter-process communication (IPC) and data center connectivity on one Ethernet fabric. There are different chassis types with different number of slots for supervisor modules.

Chassis types of Cisco Nexus 7000 Series

         The Nexus 7004 Switch: The Cisco Nexus 7004 switch chassis offers two Input/Output modules with four slots to accommodate up to 2 supervisor modules. The chassis consists of cable management frames, four power supplies and a fan tray.

         The Nexus 7009 Switch: The Cisco Nexus 7009 switch chassis offers up to seven I/O modules with up to nine slots that allow one or two supervisor modules. The chassis also has two positioning handles on each side (used to install the chassis positioning on the rack) and a front-mount bracket. In addition to that, the Cisco Nexus 7009 chassis holds one fan tray, two power supplies and five fabric modules. It also offers an optional ability to include a door and air intake frame.

         The Nexus 7010 System: The Cisco Nexus 7010 system chassis has up to eight I/O modules and ten slots for two supervisor modules. Like the Cisco Nexus 7009 chassis, the Cisco Nexus 7010 chassis has two positioning handles on each side with mounting brackets. You can also opt to include mid-frame doors and an air filter.

         The Nexus 7018 System: This system chassis offers up to 18 slots for two supervisor modules and up to 16 I/O modules. It also has two positioning handles on each side and a mounting bracket. With a cable management system the Cisco Nexus 7018 chassis holds two fan trays, four power supplies and five fabric modules. You can optionally include a front door to protect the I/O cable connections.

If you are going to take the unit out for servicing, you must make sure the rack stabilizing mechanism is used or bolt the rack to the floor as you risk the rack tipping over as you relocate the unit. You can also replace redundant components like power supply, Supervisor module I/O modules and fan trays while the Cisco Nexus 7000 Series system is operational. The Fabric module can only be replaced under the same scenarios in the Cisco Nexus 7009, 7010 and 7018 models.
