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 midspans for powering IP devices.
Q.
How many devices can the Cisco Catalyst 2960 Series power?
A.
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 ports 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 prestandard Power over Ethernet (inline power).
Q.
Can the Cisco Catalyst 2960 Series provide power to IEEE 802.3af and Cisco
prestandard Power over Ethernet simultaneously?
A.
Yes. It automatically detects the endpoint 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 Cisco IOS
®
Software supports enhanced Layer 2+ security,
quality of service (QoS), availability, and scalable management to enable new converged
applications. Cisco 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 Cisco IOS Software supports standard Layer
2 security, QoS, and availability while lowering the network total cost of ownership. Cisco
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.
