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.

Table 3. Switch Models and Corresponding Default Power Supplies

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

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.

●

Mobility controller (MC): In this mode, the Cisco Catalyst 3650 switch can perform all the mobility agent
tasks in addition to mobility coordination, radio resource management (RRM), and Cisco CleanAir®
coordination within a mobility subdomain. The mobility controller mode can be enabled on the switch CLI.
IP Base license level is required when the Cisco Catalyst 3650 switch is acting as the mobility controller.
A centrally located Cisco 5508 Wireless LAN Controller (WLC 5508), Cisco Wireless Services Module 2
(WiSM2) (when running AireOS Version 7.3), and Wireless LAN Controller 5760 can also perform this role
for larger deployments.

With mobility agents located in the wiring closets providing 40 Gbps of wireless per switch (n x 40 Gbps for
a stack of n switches) and mobility controllers managing some of the central wireless functions, the
converged access-based wireless deployment provides best-in-class scalability for wireless and significantly
improved wireless throughput.

Distributed Intelligent Services
Flexible NetFlow (FNF)

Full visibility into the wired plus wireless traffic is achieved because of the access point Control and Provisioning of
Wireless Access Points (CAPWAP) tunnel termination on the switch. This helps identify users and user traffic flows
in order to identify potential attackers and take corrective action at the access layer before the attack penetrates
further into the network. This is achieved using FNF, which monitors every single flow entering and exiting the
switch stack for wired and wireless users. It also helps identify the top wired/wireless talkers and enforce
appropriate bandwidth provisioning policies.

QoS

The 3650 switch has advanced wired plus wireless QoS capabilities. It uses the Cisco modular QoS command line
interface (MQC). The switch manages wireless bandwidth using unprecedented hierarchical bandwidth
management starting at the per-access-point level and drilling further down to per-radio, per-service set
identification (SSID), and per-user levels. This helps manage and prioritize available bandwidth between various
radios and various SSIDs (enterprise, guest, and so on) within each radio on a percentage basis. The switch is
also capable of automatically allocating equal bandwidth among the connected users within a given SSID. This
makes sure that all users within a given SSID get a fair share of the available bandwidth while being connected to
the network. The UADP ASIC enables the hierarchical bandwidth management and fair sharing of bandwidth,
thereby providing hardware-based QoS for optimized performance at line-rate traffic.

In addition to these capabilities, the switch is able to do class of service (CoS) or differentiated services code point
(DSCP) based queuing, policing, shaping, and marking of wired plus wireless traffic. This enables users to create
common policies that can be used across wired plus wireless traffic. The 3650 also supports downloadable policy
names from the Cisco Identity Services Engine (ISE) when a user successfully authenticates to the network using
the ISE.

Security

The Cisco Catalyst 3650 provides a rich set of security features for wired plus wireless users. Features such as
IEEE 802.1x, Dynamic Host Configuration Protocol (DHCP) snooping, IP Source Guard and control plane
protection, wireless intrusion prevention systems (WIPSs), and so on enable protection against unauthorized users
and attackers. With a variety of wired plus wireless users connecting to the network, the switch supports session­aware networking, in which each device connected to the network is identified as one session, and unique access
control lists (ACLs) and/or QoS policies can be defined and applied using the ISE for each of these sessions,
providing better control on the devices connecting to the network.

Resiliency

Cisco StackWise-160 Technology

The Catalyst 3650 supports an optional stacking module that is based on the Cisco StackWise-160 technology.
Cisco StackWise-160 technology is built on the highly successful industry-leading StackWise® technology, which is
a premium stacking architecture. StackWise-160 has a stack bandwidth of 160 Gbps. StackWise-160 uses Cisco
IOS Software SSO for providing resiliency within the stack. The stack behaves as a single switching unit that is
managed by an “active” switch elected by the member switches. The active switch automatically elects a standby
switch within the stack. The active switch creates and updates all the switching/routing/wireless information and
constantly synchronizes that information with the standby switch. If the active switch fails, the standby switch
assumes the role of the active switch and continues to the keep the stack operational. Access points continue to

remain connected during an active-to-standby switchover. A working stack can accept new members or delete old
ones without service interruption. StackWise-160 creates a highly resilient single unified system of up to nine
switches, providing simplified management using a single IP address, single Telnet session, single CLI, auto­version checking, auto-upgrading, auto-configuration, and more. StackWise-160 also enables local switching in
Cisco Catalyst 3650 Series Switches. (See Figure 4.)

Foundation for Open Network Environment

The heart of the Cisco Catalyst 3650 is the UADP ASIC with programmability for future features and intelligence
with investment protection. The new ASIC provides the foundation for converged APIs across wired and wireless,
Cisco Open Network Environment, software-defined networking (SDN) readiness and OnePK SDK through
software updates over the product lifetime.

detection and onboard automation. Using EEM, customers can adapt the behavior of their network devices
to align with their business needs. This feature requires the IP Base feature set.

Easy-to-Use Deployment and Control Features

●

User experience:

◦ IP service-level agreements (SLAs) enable customers to assure new business-critical IP applications, as

well as IP services that utilize data, voice, and video, in an IP network. This feature requires the IP
Services feature set.

◦ DHCP autoconfiguration of multiple switches through a boot server eases switch deployment.
◦ Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing

interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress
queue configuration.

◦ Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize

bandwidth.

◦ Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs

if an incorrect cable type (crossover or straight through) is installed.

●

Simplified configuration and connectivity:

◦ Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.
◦ Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit

EtherChannel groups to link to another switch, router, or server.

◦ Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that

conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.

◦ Unidirectional Link Detection Protocol (UDLD) and aggressive UDLD allow unidirectional links caused by

incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

◦ Cisco VLAN Trunking Protocol (VTP) Version 3 supports dynamic VLANs and dynamic trunk

configuration across all switches.

●

Efficient switch operation:

◦ Switching database manager (SDM) templates, VLAN template (specific to LAN Base license level), and

advanced template allow the administrator to automatically optimize the ternary content-addressable
memory (TCAM) allocation to the desired features based on deployment-specific requirements.

◦ Local proxy Address Resolution Protocol (ARP) works in conjunction with private VLAN edge to minimize

broadcasts and maximize available bandwidth.

◦ Stacking master configuration management with Cisco StackWise-160 technology helps make sure that

all switches are automatically upgraded when the master switch receives a new software version.
Automatic software version checking and updating help ensure that all stack members have the same
software version.

◦ Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by

downloading from a centralized location.

◦ Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.

●

Multicast:

◦ Optimized multicast for wired plus wireless: Cisco Catalyst 3650 offers greater multicast efficiency by

receiving only one multicast stream and replicating it for all connected wired plus wireless devices
connected to that switch.

◦ Internet Group Management Protocol (IGMP) v1, v2, v3 snooping for IPv4: multicast listener discovery

(MLD) v1 and v2 snooping provides fast client joins and leaves of multicast streams and limits
bandwidth-intensive video traffic to only the requestors.

●

Monitoring:

◦ Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2

switch network from any other switch in the same network.

◦ For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring

(RMON) software agent supports four RMON groups (history, statistics, alarms, and events).

◦ Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source

to destination.

◦ Wireless RF management provides both real-time and historical information about RF interference

affecting network performance across controllers using systemwide Cisco CleanAir technology
integration.

Efficient Switch Operation

Cisco Catalyst 3650 Series Switches, designed and engineered by Cisco, provide optimum power-saving, EEE,
low-power operations for industry best-in-class power management and power consumption capabilities. The Cisco
Catalyst 3650 ports are capable of reduced power modes so that ports not in use can move into a lower power
utilization state. Other efficient switch operation features are:

●

Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3650 Series Switches to negotiate a more
granular power setting when connecting to a Cisco powered device such as IP phones or access points
than what is provided by IEEE classification.

●

Per-port power consumption command allows customers to specify a maximum power setting on an
individual port. Per-port PoE power sensing measures actual power being drawn, enabling more intelligent
control of powered devices.

●

The PoE MIB provides proactive visibility into power usage and allows customers to set different power­level thresholds.

Environmentally Responsible

Organizations may choose to turn off access point radios to reduce power consumption during off-peak hours.
The integrated wireless LAN controller avoids the deployment of additional devices in the network.
