Power over Ethernet Plus (PoE+): In addition to PoE 802.3af, the Cisco Catalyst 2960-S Series Switches

support PoE+ (IEEE 802.3at standard)

, which provides up to 30W of power per port. The Cisco Catalyst 2960-

S and 2960 Series Switches simplify the deployment of solutions such as wireless LANs, IP telephony

systems, and IP video surveillance cameras. This capability eliminates the need for separate power supplies

for Ethernet-powered devices, as well as the costs of running additional cable and circuits. The switches also

provide intelligent, integrated PoE management features that give you greater visibility into and control over

your power usage and streamline interoperability in multivendor networks. Table 1 shows the power supply

combinations required for different PoE needs.

Cisco EnergyWise technology: Cisco EnergyWise is an innovative architecture embedded in the Cisco

Catalyst 2960-S and 2960 Series Switches that enables the measurement of power consumption in the

network infrastructure and network-attached devices. The network discovers Cisco EnergyWise manageable

devices, monitors their power consumption, and takes action based on business rules to reduce power

consumption. Cisco EnergyWise helps to manage power consumption, resulting in companywide optimized

power delivery and reduced energy costs. Together, Cisco EnergyWise technology and Catalyst switches help

reduce greenhouse gas emissions, optimize power consumption, and increase energy cost savings.

Enhanced security: Modern businesses face both more serious security threats and more demanding

regulatory compliance requirements than ever before. The Cisco Catalyst 2960-S and 2960 Series Switches

with LAN Base software provide a wide range of security features to protect your business’s important

information, keep unauthorized users off the network, guard privacy, and protect against network downtime

due to security breaches. Key features include:

◦ Cisco TrustSec™, provides authentication, access control, and security policy administration to secure

network connectivity and resources. On the Cisco Catalyst 2960-S and 2960 Series Switches with LAN

Base Software, the TrustSec solution prevents unauthorized access and helps ensure that users get

only their designated privileges. It provides the ability to dynamically administer granular levels of

network access.

◦ Port-level security features, to limit access to designated addresses as well as limit the number of

devices plugged into a switch port.

◦ Dynamic Host Configuration Protocol (DHCP) snooping to identify and block spoofing from

untrusted sources.
