        intelligent services, including advanced QoS, rate limiting, and 
        ACLs. The SFP-based Gigabit Ethernet ports accommodate a range of 
        SFP transceivers, including the Cisco 1000BASE-SX, 1000BASE-LX, 
        1000BASE-BX, 1000BASE-ZX, 100BASE-FX, 100BASE-LX, 100BASE-BX, and 
        coarse wavelength-division multiplexing (CWDM) SFP transceivers.
* GIGABIT ETHERNET
   At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet 
   new and evolving network demands, alleviate bottlenecks, and boost 
   performance while increasing the return on existing infrastructure 
   investments. Todays workers are placing higher demands on networks, 
   running multiple concurrent applications. For example, a worker joins a 
   team conference call through an IP videoconference, sends a 10-MB 
   spreadsheet to meeting participants, broadcasts the latest marketing 
   video for the team to evaluate, and queries the customer relationship 
   management (CRM) database for the latest real-time feedback. Meanwhile, 
   a multigigabyte system backup starts in the background and the latest 
   virus updates are delivered to the client.
* INTELLIGENCE IN THE NETWORK
   Networks of today are evolving to address four new developments at the 
   network edge:
    - Increase in desktop computing power
    - Introduction of bandwidth-intensive applications
    - Expansion of highly sensitive data on the network
    - Presence of multiple device types, such as IP phones, WLAN access 
      points, and IP video cameras.
   These new demands contend for resources with existing mission-critical 
   applications. As a result, IT professionals must view the edge of the 
   network as critical to effectively manage the delivery of information 
   and applications.
   As companies increasingly rely on networks as their strategic business 
   infrastructure, it is more important than ever to ensure their high 
   availability, security, scalability, and control. By adding Cisco 
   intelligent functions for LAN access, you can now deploy networkwide 
   intelligent services that consistently address these requirements from 
   the desktop to the core and through the WAN.
   With Cisco Catalyst Intelligent Ethernet switches, Cisco Systems helps 
   companies realize the full benefits of adding intelligent services into 
   their networks. Deploying capabilities that make the network 
   infrastructure highly available to accommodate time-critical needs, 
   scalable to accommodate growth, secure enough to protect confidential 
   information, and capable of differentiating and controlling traffic 
   flows is critical to further optimizing network operations.
* ENHANCED SECURITY
   The wide range of security features that the Cisco Catalyst 2960 Series 
   offers helps businesses protect important information, keep unauthorized 
   people off the network, guard privacy, and maintain uninterrupted 
   operation.
   The Cisco Identity Based Networking Services (IBNS) solution provides 
   authentication, access control, and security policy administration to 
   secure network connectivity and resources. Cisco IBNS in the Cisco 
   Catalyst 2960 Series 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. Using the 
   802.1x standard and the Cisco Secure Access Control Server (ACS), users 
   can be assigned a VLAN upon authentication, regardless of where they 
   connect to the network. This setup allows IT departments to enable 
   strong security policies without compromising user mobility, and with 
   minimal administrative overhead.
   To guard against denial-of-service and other attacks, ACLs can be used 
   to restrict access to sensitive portions of the network by denying 
   packets based on source and destination MAC addresses, IP addresses, or 
   TCP/User Datagram Protocol (UDP) ports. ACL lookups are done in 
   hardware, so forwarding performance is not compromised when implementing 
   ACL-based security.
   Port security can be used to limit access on an Ethernet port based on 
   the MAC address of the device to which it is connected. It also can be 
   used to limit the total number of devices plugged into a switch port, 
   thereby protecting the switch from a MAC flooding attack as well as 
   reducing the risks of rogue wireless access points or hubs.
   With Dynamic Host Configuration Protocol (DHCP) snooping, DHCP spoofing 
   can be thwarted by allowing only DHCP requests (but not responses) from 
   untrusted user-facing ports. Additionally, the DHCP Interface Tracker 
   (Option 82) feature helps enable granular control over IP address 
   assignment by augmenting a host IP address request with the switch port 
   ID.
   The MAC Address Notification feature can be used to monitor the network 
   and track users by sending an alert to a management station so that 
   network administrators know when and where users entered the network. 
   Secure Shell Protocol Version 2 (SSHv2) and Simple Network Management 
   Protocol Version 3 (SNMPv3) encrypt administrative and network-
   management information, protecting the network from tampering or 
   eavesdropping. TACACS+ or RADIUS authentication enables centralized 
   access control of switches and restricts unauthorized users from 
   altering the configurations. Alternatively, a local username and 
   password database can be configured on the switch itself. Fifteen levels 
   of authorization on the switch console and two levels on the Web-based 
   management interface provide the ability to give different levels of 
   configuration capabilities to different administrators.
* AVAILABILITY AND SCALABILITY
   The Cisco Catalyst 2960 Series is equipped with a large set of features 
   that allow for network scalability and higher availability through 
   multicast filtering as well as a complete suite of Spanning Tree 
   Protocol enhancements aimed to maximize availability in a Layer 2 
   network.
   Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN 
   Spanning Tree Plus (PVST+), UplinkFast, and PortFast, help to maximize 
   network uptime. PVST+ allows for Layer 2 load sharing on redundant links 
   to efficiently use the extra capacity inherent in a redundant design. 
   UplinkFast, PortFast, and BackboneFast all greatly reduce the standard 
   30- to 60-second Spanning Tree Protocol convergence time. Flexlink 
   provides bidirectional, fast convergence in less than 100 milliseconds. 
   The Loopguard and bridge protocol data unit (BPDU) guard enhancements 
   provide Spanning Tree Protocol loop avoidance.
* ADVANCED QOS
   The Cisco Catalyst 2960 Series offers superior multilayer QoS features 
   to help ensure that network traffic is classified and prioritized, and 
   that congestion is avoided in the best possible manner. Configuration of 
   QoS is greatly simplified through automatic QoS (Auto QoS), a feature 
   that detects Cisco IP phones and automatically configures the switch for 
   the appropriate classification and egress queuing. This optimizes 
   traffic prioritization and network availability without the challenge of 
   a complex configuration.
   The Cisco Catalyst 2960 Series can classify, reclassify, police, mark, 
   queue, and schedule incoming packets and can queue and schedule packets 
   at egress. Packet classification allows the network elements to 
   discriminate between various traffic flows and enforce policies based on 
   Layer 2 and Layer 3 QoS fields.
   To implement QoS, the Cisco Catalyst 2960 Series Switch first identifies 
   traffic flows or packet groups, then classifies or reclassifies these 
   groups using the differentiated services code point (DSCP) field or the 
   802.1p class of service (CoS) field. Classification and reclassification 
   can be based on criteria as specific as the source or destination IP 
   address, source or destination MAC address, or the Layer 4 TCP or UDP 
   port. At the ingress, the Catalyst 2960 Series also polices to determine 
   whether a packet is in or out of profile, marks to change the 
   classification label, passes through or drops out of profile packets, 
   and queues packets based on classification. Control-plane and data-plane 
   ACLs are supported on all ports to help ensure proper treatment on a 
   per-packet basis.
   The Cisco Catalyst 2960 Series supports four egress queues per port, 
   giving network administrators more control in assigning priorities for 
   the various applications on the LAN. At egress, the switch performs 
   congestion control and scheduling, the algorithm or process that 
   determines the order in which queues are processed. The Catalyst 2960 
   Series Switch supports Shaped Round Robin (SRR) and strict priority 
   queuing. The SRR algorithm helps ensure differential prioritization.
   These QoS features allow network administrators to prioritize mission-
   critical and bandwidth-intensive traffic, such as enterprise resource 
   planning (ERP), voice (IP telephony traffic), and computer-aided design 
   and manufacturing (CAD/CAM), over applications such as FTP or e-mail. 
   For example, it would be undesirable to have a large file download 
   destined to one port on a switch increase latency in voice traffic 
   destined to another port on this switch. This condition is avoided by 
   ensuring that voice traffic is properly classified and prioritized 
   throughout the network. Other applications, such as Web browsing, can be 
   handled on a lower-priority basis.
   The Cisco Catalyst 2960 Series can perform rate limiting through its 
   support of the Cisco committed information rate (CIR) function. Through 
   CIR, bandwidth can be guaranteed in increments as small as 1 Mbps. 
   Bandwidth can be allocated based on several criteria, including MAC 
   source address, MAC destination address, IP source address, IP 
   destination address, and TCP or UDP port number. Bandwidth allocation is 
   essential when network environments require service-level agreements or 
   when it is necessary to control the bandwidth given to certain users.
* MANAGEMENT
   The new Express Setup feature simplifies the initial configuration of a 
   switch. Now you can set up the switch through a Web browser, eliminating 
   the need for terminal-emulation programs and the command-line interface 
   (CLI). Express Setup reduces the cost of deployment by helping less-
   skilled personnel quickly and easily set up switches.
   Cisco Network Assistant is a PC-based network-management application 
   optimized for LANs with up to 250 users. Cisco Network Assistant offers 
   centralized management of Cisco switches, routers, and WLAN access 
   points. It supports a wide range of Cisco Catalyst intelligent switches 
   from Cisco Catalyst 2960 through Cisco Catalyst 4506. Through a user-
   friendly GUI, users can configure and manage a wide array of switch 
   functions and start the device manager of Cisco routers and Cisco 
   wireless access points. A few mouse clicks enable the Cisco recommended 
   security, availability, and QoS features without the need to consult a 
   detailed design guide. The Security wizard automatically restricts 
   unauthorized access to servers with sensitive data. Smartports and 
   wizards save time for network administrators, reduce human errors, and 
   help ensure that the configuration of the switch is optimized for these 
   applications. Available at no cost, Cisco Network Assistant can be 
   downloaded from the Cisco Website.
   In addition to Cisco Network Assistant, Cisco Catalyst 2960 Series 
   switches provide for extensive management using SNMP network-management 
   platforms such as CiscoWorks for Switched Internetworks. Managed with 
   CiscoWorks, Cisco Catalyst switches can be configured and managed to 
   deliver end-to-end device, VLAN, traffic, and policy management. 
   Additionally, the CiscoWorks Resource Manager Essentials, a Web-based 
   management tool, helps enable automated inventory collection, software 
   deployment, easy tracking of network changes, views into device 
   availability, and quick isolation of error conditions.

POWER CONNECTORS-
               Customers can provide power to a switch by using either the 
                 internal power supply or the Cisco RPS 675. 
               Internal Power Supply Connector:
                  The internal power supply is an auto-ranging unit.
                  The internal power supply supports input voltages between 
                    100 and 240 VAC.
                  Use the supplied AC power cord to connect the AC power 
                    connector to an AC power outlet.                   
                  The connector offers connection for an optional Cisco RPS 
                    675 that uses AC input and supplies DC output to the 
                    switch.
                  The connector offers a 675W redundant power system that 
                    supports up to six external network devices and 
                    provides power to one failed device at a time.
                  The connector automatically senses when the internal 
                    power supply of a connected device fails and provides 
                    power to the failed device, preventing loss of network 
                    traffic.
                  Only the Cisco RPS 675 (model PWR675-AC-RPS-N1=) should 
                    be attached to the redundant-power-supply receptacle.
