Product Overview
Q. What is the Cisco Catalyst 2960PD-8TT-L compact switch?
A. The Cisco® Catalyst® 2960PD-8TT-L switch has eight 10/100 Mbps ports and receives power over the Gig uplink port from an upstream power over Ethernet (PoE) switch. The Cisco Catalyst 2960 powered device (PD) switch is ideal for deployments outside the wiring closet such as conference rooms and classrooms with spacing and wiring constraints.
Q. How can the Cisco Catalyst 2960PD-8TT-L compact switch be powered?
A. The Cisco Catalyst 2960PD-8TT-L can be powered by another PoE switch, a power adaptor or power injectors that support 802.3af, including AIR-PWRINJ4. The Cisco Catalyst 2960PD-8TT-L switch prioritizes the power adaptor over PoE input when both the power adaptor and the PoE input port are activated. The Cisco Catalyst 2960PD-8TT-L power adaptor and power cord are optional and sold separately
Q. What are the benefits of Power over Ethernet ?
A. Power over Ethernet can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones and Cisco Aironet® wireless LAN access points, as well as any IEEE 802.3af compliant end device. Power over Ethernet removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling that would otherwise be necessary in IP phone and wireless LAN deployments. PoE switches also eliminate the need for power injectors and PoE mid-spans for powering IP devices.
Q. How many devices can the Cisco Catalyst 2960 Series power?
A. The Cisco Catalyst 2960-48PST-L can support 48 PoE ports with total PoE power output capacity at 370W. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 2960-48PST-L configuration can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. The Cisco Catalyst 2960-24PC-L can support 24 simultaneous full-powered PoE devices at 15.4W for maximum powered-device support. The Cisco Catalyst 2960-24LT-L can support eight PoE devices at 15.4W.
Q. Can Cisco Catalyst 2960 LAN Base switches support devices that require more than 15.4W?
A. No, Cisco Catalyst 2960 LAN Base switches support only up to 15.4W on PoE ports. The Cisco Catalyst 2960-24PC-L can support 24 simultaneous full-powered PoE port at 15.4W for maximum powered-device support. The Cisco Catalyst 2960-24LT-L24 has 24 10/100 ports with 8 simultaneous full-powered PoE ports at 15.4W. For support of higher than 15.4W, Cisco Catalyst 3560-E and 3750-E series switches are recommended.
Q. Does the Cisco Catalyst 2960 Series support standards-based Power over Ethernet?
A. Yes. The Cisco Catalyst 2960 Series supports IEEE 802.3af, and it provides investment protection for the installed base of Cisco IP phones and Cisco Aironet wireless LAN access points by also supporting the Cisco pre-standard Power over Ethernet (inline power).
Q. Can the Cisco Catalyst 2960 Series provide power to IEEE 802.3af and Cisco pre-standard Power over Ethernet simultaneously?
A. Yes. It automatically detects the end point to provide the appropriate power without any user intervention.
Q. What are the advantages of Cisco Catalyst 2960 Series Switches with the LAN Base software relative to Cisco Catalyst 2960 Series Switches with the LAN Lite software?
A. Cisco Catalyst 2960 LAN Base switches deliver intelligent services for branch offices and wiring closets. The LAN Base IOS software supports enhanced Layer 2+ security, quality of service (QoS), availability, and scalable management to enable new converged applications. Catalyst 2960 LAN Base switches include both 10/100 Fast Ethernet and 10/100/1000 Gigabit Ethernet connectivity in 8-, 24-, and 48-port configurations.
Cisco Catalyst 2960 LAN Lite switches are for entry-level branch office and wiring closet networks. They simplify the migration from nonintelligent hubs and unmanaged switches to a fully scalable and reliable network. The LAN Lite IOS software supports standard Layer 2 security, QoS, and availability while lowering the network total cost of ownership. Catalyst 2960 LAN Lite switches deliver 10/100 Fast Ethernet connectivity in 24- and 48-port configurations.
All Cisco Catalyst 2960 Series Switches have technical support service options available through Cisco SMARTNet® service. All come with a Limited Lifetime Hardware Warranty, and LAN Base and LAN Lite software updates are provided at no additional cost.
Q. What are the advantages of Cisco Catalyst 2960 PoE Series Switches and Cisco Catalyst 3560/3750 PoE Series Switches?
A. The Catalyst 2960 Series PoE switches with intelligent services are ideally suited for small branch offices that can benefit from converged networks. The Catalyst 2960 Series provides enhanced security, scalable management, and unified network services for applications such as unified communications and mobility. The Catalyst 3750 and 3560 with advanced intelligent services are better suited for enterprise and mid-market campus wiring closets as well as large branch offices. The Catalyst 3750 and 3560 Series switches provide investment protection and deliver increased availability and scalability through advanced L3 services, advanced security such as man-in-the-middle attack threat mitigation features, and increased control for applications like Telepresence.
Q. What are Cisco Catalyst 2960 Compact Switches?
A. Cisco Catalyst 2960 Compact Switches are small form-factor switches designed for deployments outside the wiring closet. They have a durable metal shell, no fan for silent operation, easy wall or under-the-desk mounting, a security lock to prevent theft, and an available cable guard to secure the Ethernet cables and switch. Now you can deliver intelligent services such as Network Admission Control for the office workspace, micro branch office, classroom, cruise ship, and other wiring-constrained environments. Table 1 describes the Cisco Catalyst 2960 Compact Switch portfolio.

Q. Do Cisco Catalyst 2960 Series Switches have redundant power supply (RPS) support?
A. Yes. The following Cisco Catalyst 2960 Series Switches have RPS support:

• Catalyst 2960-24TT-L

• Catalyst 2960-24TC-L

• Catalyst 2960-24PC-L

• Catalyst 2960-48PST-L

• Catalyst 2960-24LT-L

• Catalyst 2960-48TT-L

• Catalyst 2960-48TC-L

• Catalyst 2960G-24TC-L

• Catalyst 2960G-48TC-L
A converged voice and data network has the greatest power availability when a Cisco Catalyst 2960 Series Switch is combined with the Cisco RPS 2300 Redundant Power System for protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages. For more information about the Cisco RPS 2300, visit http://www.cisco.com/en/US/products/hw/routers/ps2883/ps5066/index.html.
The Cisco Catalyst 2960 Compact Switches and Cisco Catalyst 2960 LAN Lite Switches do not have RPS support.
Q. What are the notable differences between the Cisco Catalyst 2960 LAN Base and LAN Lite switches?
A. Cisco Catalyst 2960 LAN Base switches have several advantages:

• Gigabit Ethernet connectivity in 8-, 24-, and 48-port configurations
