Alternatively, for deployments that do not need maximum power, a smaller power supply makes
use of Cisco Catalyst Intelligent Power Management to support 24 ports at 15.4W, 48 ports at
7.7W, or any combination in between.
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.
●
Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by
issuing interface and global switch commands to detect Cisco IP phones, classify traffic,
and help enable egress queue configuration.
●
Master configuration management helps ensure that all switches are automatically
upgraded when the master switch receives a new software version. Automatic software
version checking and updating help ensure that all stack members have the same software
version.
●
Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to
optimize bandwidth.
●
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all
switch ports.
●
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel
®
groups or Gigabit EtherChannel groups to link to another switch, router, or server.
●
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with
devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel
technology and PAgP.
●
Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and
receive pairs if an incorrect cable type (crossover or straight-through) is installed.
