Power over Ethernet

The Cisco Catalyst 2960 Series provide PoE to allow easy connectivity to Ethernet-powered
devices including Cisco IP phones and wireless access points. Cisco Catalyst 2960 PoE models
comply with Cisco pre-standard PoE and IEEE 802.3af. PoE removes the need for wall power to
each PoE-enabled device and eliminates the cost for additional electrical cable and circuits that
would otherwise be necessary in IP phone and WLAN deployments. PoE switches also eliminate
the need for power injectors and PoE mid-spans for powering IP devices. 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. Cisco Catalyst 2960-24PC-L can support 24 simultaneous full-
powered PoE port at 15.4W. The Cisco Catalyst 2960-24LT-L has 24 10/100 ports with 8
simultaneous full-powered PoE ports at 15.4W.
The Cisco Catalyst 2960-8TT-L has eight 10/100 ports with one 10/100/1000 PoE input port. This
switch does not need a power supply and receives power over the uplink from an upstream PoE
device, providing deployment flexibility and availability. It is ideal for wiring and space-constraint
applications. The power adaptor (PWR-A=) and power cord are optional and may be ordered
separately.

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. Today's 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.

Redundant Power System

The Cisco Catalyst 2960 Series Switches support the new generation of the Cisco Redundant
Power System (RPS) 2300, which increases availability in a converged data, voice, and video
network by providing transparent power backup to two of six attached switches at the same time.
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.
