Data Sheet

Maximum power availability for converged voice and data networks is attainable when a Cisco

Catalyst 3750-E Series Switch is combined with the Cisco RPS 2300 Redundant Power System for

transparent protection against internal power supply failures and an uninterruptible power supply

(UPS) system to safeguard against power outages. Using the RPS 2300 to provide backup power,

the Cisco Catalyst 3750-E Series Switch power supplies become hot swappable. Table 3 shows

the power supply compatibility matrix.

Power over Ethernet

The Cisco Catalyst 3750-E Series can provide a lower total cost of ownership for deployments that

incorporate Cisco IP phones, Cisco Aironet

wireless LAN (WLAN) access points, or any IEEE

802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device

and eliminates the cost for additional electrical cabling and circuits that would otherwise be

necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750-E 24-port PoE

configurations can support 24 simultaneous full-powered PoE ports at 15.4W for full powered-

device support. The Cisco Catalyst 3750-E 48-port PoE configurations can support 48

simultaneous full-powered PoE ports at 15.4W when using the optional 1150W power supply.

Alternatively, for deployments that do not need full PoE on all ports, a smaller power supply can be

used in conjunction with Cisco Catalyst Intelligent Power Management to support 24-port and 48-

port PoE configurations.

In addition, Cisco Catalyst Intelligent Power Management supports Enhanced PoE where up to

20W of PoE can be delivered to each port. This capability enables support of PoE devices such as

802.11n wireless equipment where >15.4W of PoE is required.

Redundant Power System

The Cisco Catalyst 3750-E Series Switches support the new generation of Redundant Power

Supply (RPS) 2300. The RPS 2300 increases availability in a converged data, voice, and video

network by providing transparent power backup to two of six attached Cisco Catalyst 3750-E

Series Switches at the same time. The failed power supply can be swapped out while the switch is

being powered up by the RPS 2300.

Primary Features and Benefits

Ease of Use: Deployment

A working stack is self-managing and self-configuring. When switches are added or removed, the

master switch automatically loads the Cisco IOS Software version running on the stack to the new

switch, loads the global configuration parameters, and updates all the routing tables to reflect

changes. Upgrades are applied universally and simultaneously to all members of the stack.

The Cisco Catalyst 3750-E Series stacks up to nine switches as a single logical unit for a total of

468 Ethernet 10/100/1000 ports, 432 PoE 10/100/1000 ports, or 18 10 Gigabit Ethernet ports.

Individual 10/100/1000 units can be joined in any combination to evolve with network needs.

Other ease of use features include but are not limited to:

●

Smartports enable fast and easy configuration of Cisco recommended best practice

security and QoS features, encapsulating years of Cisco networking expertise.

●

Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches

through a boot server eases switch deployment.
