Cisco Catalyst 3650 Series Switches

The Cisco Catalyst^® 3650 Series is the next generation of enterprise-class standalone and stackable access-layer switches that provide the foundation for full convergence between wired and wireless on a single platform. The Cisco Catalyst 3650 is built on the advanced Cisco StackWise^®-160, and takes advantage of the new Cisco^® Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC). This switch can enable uniform wired-wireless policy enforcement, application visibility, flexibility, application optimization, and superior resiliency. The Cisco Catalyst 3650 Series Switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), and offer modular and field-replaceable redundant fans and power supplies. They can help you increase wireless productivity and reduce your TCO.

Switch Models and Configurations

All Cisco Catalyst 3650 Series Switches have fixed, built-in uplink ports and ship with one power supply. Tables 1 through 5 provide further details. Figure 1 is an image of the Cisco Catalyst 3650 Series Switches.

Figure 1.Cisco Catalyst 3650 Series Switches

Table 1 shows the Cisco Catalyst 3650 Series configurations.

Fixed Uplinks

All Cisco Catalyst 3650 Series Switches have fixed, built-in uplink ports. Customers can choose from three types of uplink ports at the time of the switch purchase:

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+ or 4 x Gigabit Ethernet with SFP

The SFP+ interface supports both 10 Gigabit Ethernet and Gigabit Ethernet ports. Refer to Table 1 for a description of the basic switch models and the corresponding uplink ports. Refer to Table 2 for a description of the various uplink port interface options.

Dual Redundant Modular Power Supplies

The Cisco Catalyst 3650 Series Switches support dual redundant power supplies (See Figure 2). The switch ships with one power supply by default, and the second power supply can be purchased at the time of ordering the switch or at a later time. If only one power supply is installed, it should always be in power supply bay 1. The switch also ships with three field-replaceable fans.

Figure 2.Redundant Power Supplies

Table 3 shows the different power supplies available in these switches and available PoE power.

In addition to the power supplies listed in Table 3, a 640 WDC power supply is available at the time of order or as a spare on all switch models. The DC power supply also delivers PoE capabilities for maximum flexibility (refer to Table 5 for available PoE budget with DC power supplies). Customers can mix and match the AC and DC power supplies in the two available power supply slots. Any of these power supplies can be installed in any of the switches.¹

¹ The 250 WAC power supply will be supported on the PoE-capable switches in a future release.

Power over Ethernet Plus (PoE+)

The Cisco Catalyst 3650 Series Switches support both PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at standard), which provide up to 30 W of power per port. 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. The Cisco Catalyst 3650 Series Switches can provide a lower TCO for deployments that incorporate Cisco IP phones, Cisco Aironet^® wireless LAN (WLAN) access points, or any IEEE 802.3at-compliant end device. Table 5 shows the power supply combinations required for different PoE needs.

Benefits

Converged Wired plus Wireless Access

The Cisco Catalyst 3650 is a standalone and stackable access switching platform that enables wired plus wireless services on a single Cisco IOS XE Software-based platform. With this, Cisco has pioneered a host of rich capabilities such as high availability based on stateful switchover (SSO) on stacking, granular QoS, security, and Flexible Netflow (FNF) across wired and wireless in a seamless fashion. Also, the wired plus wireless features are bundled into a single Cisco IOS Software image, which reduces the number of software images that users have to qualify/certify before enabling them in their network. The single console port for command-line interface (CLI) management reduces the number of touch points to manage for wired plus wireless services, thereby reducing network complexity, simplifying network operations, and lowering the TCO to manage the infrastructure.

Converged wired plus wireless not only improves wireless bandwidth across the network but also the scale of wireless deployment. Each 48-port Cisco Catalyst 3650 provides 40 Gbps of wireless throughput (20 Gbps on the 24-port model). This wireless capacity increases with the number of members in the stack. This makes sure that the network can scale with current wireless bandwidth requirements, as dictated by IEEE 802.11n-based access points and with future wireless standards such as IEEE 802.11ac. Additionally, the Cisco Catalyst 3650 distributes the wireless controller functions to achieve better scalability. Each Cisco Catalyst 3650 switch/stack can operate as the wireless controller in two modes:

Mobility agent (MA): This is the default mode in which the Cisco Catalyst 3650 switch ships. In this mode the switch is capable of terminating the CAPWAP tunnels from the access points and providing wireless connectivity to wireless clients. Maintaining wireless client databases and configuring and enforcing security and QoS policies for wireless clients and access points can be enforced in this mode. No additional license on top of IP Base is required to operate in the mobility agent mode.
