รายละเอียดทั้งหมด :

The Cisco^® Catalyst^® 3750-E Series Switches with StackWise Plus (Figure 1) is an enterprise-class line of stackable wiring closet switches that facilitates the deployment of secure converged applications while maximizing investment protection for evolving network and application requirements. Combining 10/100/1000 and Power over Ethernet (PoE) configurations with 10 Gigabit Ethernet uplinks, the Cisco Catalyst 3750-E enhances worker productivity by enabling applications such as IP telephony, wireless, and video.

Cisco Catalyst 3750-E Series Primary Features

Cisco TwinGig converter module for migrating uplinks from Gigabit Ethernet to 10 Gigabit Ethernet
Cisco EnergyWise for greenhouse gas emissions and operational cost optimization by measuring, reporting, and reducing energy consumption across the entire corporate infrastructure, well beyond the scope of IT
PoE configurations with up to 15.4 W of PoE on all 48 ports
Enhanced PoE supporting up to 20W of PoE per port
StackWise Plus for ease of use and resiliency with 64 Gbps of throughput
Modular power supply with externally available backup
Multicast routing, IPv6 routing, and access control list in hardware
Out-of-band Ethernet management port along with RS-232 console port

Cisco Catalyst 3750-E Software

Cisco Catalyst 3750-E Series is available with either the IP Base or the IP Services feature set. The IP Base feature set includes advanced quality of service (QoS), a suite of security features, rate-limiting, access control lists, and basic static and Routing Information Protocol (RIP) routing capability. The IP Services feature set provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing-Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.

10 Gigabit Ethernet Uplinks and the Cisco TwinGig SFP Converter

The Cisco Catalyst 3750-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications, relieving congestion and ensuring smooth delivery of data. The TwinGig SFP converter (see Figure 2) converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports. This way, customers can initially use the switch with Gigabit Ethernet uplinks and later implement 10 Gigabit Ethernet uplinks as business demands change, without having to upgrade the access layer.

Modular Power Supplies

The Cisco Catalyst 3750-E Series Switches have one power supply slot and support the following power supplies. PoE switches require a PoE power supply. Data-only switches can operate with any of the power supplies.

C3K-PWR-1150WAC: 1150WAC power supply with 800W PoE
C3K-PWR-750WAC: 750WAC power supply for 24-port switch with 420W PoE
C3K-PWR-265WAC: 265WAC power supply for 48-port or 24-port switch without PoE
C3K-PWR-265WDC: 265WDC power supply for 48-port or 24-port switch without PoE

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.
