Cisco Catalyst 3850 Fiber Switch Model

Cisco Catalyst 3850 Fiber Switch Model

Cisco Catalyst 3850 is generally new Launched Cisco Switch with the Fiber Connectivity Capabilities. It can be used in the Data-Center environment for various purposes.

Lets discuss about this switch in details as below:

The Cisco Catalyst 3850 Series is the next generation of enterprise-class stackable Ethernet and Multi-gigabit Ethernet access and aggregation layer switches that provide full convergence between wired and wireless on a single platform. 

Cisco’s new Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC) powers the switch and enables uniform wired-wireless policy enforcement, application visibility, flexibility and application optimization. 

This convergence is built on the resilience of the new and improved Cisco StackWise-480 technology. The Cisco Catalyst 3850 Series Switches support full IEEE 802.3 at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (Cisco UPOE), modular and field-replaceable network modules, RJ45 and fiber-based downlink interfaces, and redundant fans and power supplies. 

With speeds that reach 10Gbps, the Cisco Catalyst 3850 Multi-gigabit Ethernet Switches support current and next-generation wireless speeds and standards (including 802.11ac Wave 2) on existing cabling infrastructure

Product Overview

Integrated wireless controller capability with: 
  • Up to 40G of wireless capacity per switch (48-port models) 
  • Support for up to 50 access points and 2000 wireless clients on each switching entity (switch or stack)
  • 24 and 48 10/100/1000 data PoE+ and Cisco UPOE models with energy-efficient Ethernet (EEE) Cisco StackWise-480 technology provides scalability and resiliency with 480 Gbps of stack throughput 
  • Cisco Stack Power technology provides power stacking among stack members for power redundancy Three optional uplink modules with 4 x Gigabit Ethernet, 2 x 10 Gigabit Ethernet, or 4 x 10 Gigabit Ethernet ports 
  • Dual redundant, modular power supplies and three modular fans providing redundancy  Full IEEE 802.3at (PoE+) with 30W power on all ports in 1 rack unit (RU) form factor 
  • Cisco UPOE with 60W power per port in 1 rack unit (RU) form factor
  • Software support for IPv4 and IPv6 routing, multicast routing, modular quality of service (QoS), Flexible NetFlow (FNF) Version 9, and enhanced security features
  • Single universal Cisco IOS Software image across all license levels, providing an easy upgrade path for software features
  • Enhanced limited lifetime warranty (E-LLW) with next business day (NBD) advance hardware replacement and 90-day access to Cisco Technical Assistance Center (TAC) support

Network Modules

The Cisco Catalyst 3850 Series Switches support three optional network modules for uplink ports. The default switch configuration doesn’t include the uplink module. At the time of switch purchase the customer has the flexibility to choose from the network modules
  • 4 x Gigabit Ethernet with Small Form-Factor Pluggable (SFP)
  • 2 x 10 Gigabit Ethernet with SFP+ or 4 x Gigabit Ethernet with SFP
  • 4 x 10 Gigabit Ethernet with SFP+ (supported on the 48-port models only)

The C3850-NM-4-10G module is supported on the 48-port models only. The SFP+ interface supports both 10 Gigabit Ethernet and Gigabit Ethernet ports, allowing customers to use their investment in Gigabit Ethernet SFP and upgrade to 10 Gigabit Ethernet when business demands change without having to do a comprehensive upgrade of the access switch. The three network modules are hot swappable

Power over Ethernet Plus (PoE+)

In addition to PoE (IEEE 802.3af), the Cisco Catalyst 3850 Series Switches support PoE+ (IEEE 802.3at standard), which provides up to 30W of power per port. The Cisco Catalyst 3850 Series Switches can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3at-compliant end device. 

PoE removes the need for wall power to each PoE enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. Table 6 shows the power supply combinations required for different PoE needs.

Cisco Universal Power over Ethernet (UPOE)

Cisco Universal Power over Ethernet is a breakthrough technology, offering the following services and benefits:
  • 60W per port to enable a variety of end devices such as Samsung VDI client, BT IP turret systems in trading floors, Cisco Catalyst compact switches in retail/hospitality environments, personal Cisco Telepresence systems, and physical access control devices
  • High availability for power and guaranteed uninterrupted services, a requirement for critical applications (e911)
  • Lowering OpEx by providing network resiliency at lower cost by consolidating backup power into the wiring closet
  • Faster deployment of new campus access networking infrastructures by eliminating the need for a power outlet for every endpoint
