Arista Network Convergence System 5500 Series

 



 

 


Three variants of the Arista network NCS5500 modular chassis, the NCS 5504, NCS 5508, and NCS 5516 chassis feature a Clos fabric-line card connecting design That's what I mean. Back-mounted fabric module. Supports up to six switch fabric cards per system, with all fabric cards directly connected to all line cards. This architecture provides optimal bandwidth distribution within the chassis by distributing the load among the fabric cards.

 

Cisco NCS 5500 Series Fan Trays

The NCS 5504, NCS 5508, and NCS 5516 chassis with front-to-back cooling support three hot-swappable fan trays. The fabric modules are behind the fan trays, and each fan tray covers two fabric modules. The fan trays provide N+1 redundancy and each fan tray can be removed simultaneously during operation to access the underlying fabric cards.

 

Cisco NCS 5500 Generation 2 Fabric Cards and Fan Trays

IOS-XR version 6.6.25 introduces new generation fabric cards and fan trays for NCS-5508 (NC55-5508-FC2 and NC55-5508-FAN2) and A fan tray is introduced. 5516 on (NC55-5516-FC2 and NC55-5516-FAN2). A new generation of fabric cards and fan trays for NCS-5504 (NC55-5504-FC2 and NC55-5504-FAN2) are introduced in IOS-XR versions 7.2.2 and 7.3.1. The second generation fabric cards and fan trays enable the addition of NCS 5700 400 GE and 100 GE line cards to the NCS-5504, NCS-5508, and NCS-5516. For more information, see the 2nd Generation Fabric Card and Fan Tray datasheet.

 

Cisco NCS 5500 Series Routing Processors

A pair of redundant routing processor cards manage all routing operations on the Cisco NCS 5504, Cisco NCS 5508, and NCS 5516 chassis.

 

Cisco NCS 5500 Series Power Supplies

The Cisco NCS 5500 Series supports hot-swappable front-access power supplies. N+1 and N+N (grid) redundancy modes are supported on fully loaded Cisco NCS 5504 and NCS 5508, N+1 and N+M redundancy modes are supported on fully loaded Cisco NCS 5516 . The 3000W AC and DC power supplies are rated 80 Plus Platinum and deliver over 92% efficiency under typical workloads.

The new 4.4 kW DC power supply (NC55-PWR-4.4KW-DC) supports N+1 and N+N feeder redundancy on the NCS 5504, NCS 5508, and NCS 5516.

Fiber optic networks operate

Image
  PON standards Fiber optic networks operate according to various standards for Passive Optical Networks (PON). PON is a network system designed specifically for fiber optic technology to provide broadband network access to homes and businesses. One of the many PON standards is GPON. GPON stands for Gigabit Ethernet Passive Optical Network (PON). GPON uses Asynchronous Transfer Mode (ATM) for voice, Ethernet for data, and a proprietary encapsulation for voice. This means that fixed-size cells are used instead of variable-size data packets. It offers faster Gbit/s in downstream and upstream bandwidth than EPON (Ethernet Passive Optical Network). GPON system consists of an Optical Line Terminal (OLT) that connects multiple Optical Network Terminals (ONT/ONU) over a Passive Optical Distribution Network (ODN).   GPON supports: • Triple-play services (VoIP, data, IPTV) and offers competitive all-service solutions. • Higher data rates and bandwidth • Longer distance...
