3750-E系列交换机提供标准软件镜像、增强服务软件镜像和高级服务软件镜像。标准软件镜像包括先进的服务质量（QoS）、安全特性集、速率限制、访问控制列表（ACL）和基本的静态和路由信息协议（RIP）路由功能软件。增强服务软件镜像可以提供一组更加丰富的企业级功能，包括先进的、基于硬件的IP单播和组播路由。高级服务软件镜像则进一步提供了对IPv6路由的支持。客户可以通过思科IOS软件激活流程，平滑的升级思科 Catalyst 3750-E系列交换机。思科IOS软件激活流程可以授权并激活交换机内的软件功能特性集。交换机加电启动时，思科 IOS软件会检测交换机内的一个许可文件，并根据许可文件的类型，激活对应的软件功能特性集。客户可以通过对许可文件更改、升级来激活不同的软件功能特性集。投资保护思科 Catalyst 3750-E系列交换机与思科 Catalyst 3750系列交换机兼容，客户可以将这两个系列的交换机混合堆叠使用，从而保护现有思科 Catalyst 3750系列交换机上的投资。思科Catalyst 3750-E系列交换机支持的TwinGig SFP转换模块可以根据业务需求从千兆上联升级到万兆以太网上联，而无需升级交换机本身。思科StackWise Plus技术利用特殊的堆叠互联电缆和堆叠软件，思科StackWise技术最多可以将9台单独的思科 Catalyst 3750交换机连接到一个统一的逻辑单元中。堆叠相当于一个单一的交换单元，由一个从成员交换机中选出的主交换机管理。主交换机可以自动地创建和升级所有的交换信息和可选的路由表。一个工作中的堆叠可以在不中断服务的情况下，添加新的成员或者移除旧的成员。最新的思科StackWise Plus技术提供64Gbps的吞吐能力，支持并向下兼容StackWise 技术的所有技术特性。万兆以太网上行和思科TwinGig SFP转换模块思科 Catalyst 3750-E系列交换机的万兆上行端口用于高带宽应用，可避免拥塞和保证数据平滑传输。思科TwinGig SFP转换模块（图2）可将一个万兆以太网X2端口转换为两个千兆SFP端口。客户可在最初使用千兆上行，在业务需要时迅速平滑的升级至万兆上行，而无需升级交换机本身。图二、思科TwinGig SFP转换模块模块化电源供电思科 Catalyst 3750-E系列交换机内置一个电源模块槽位，支持以下型号的电源模块。PoE交换机需要一个PoE电源模块，如仅支持数据应用则可以使用所有型号的电源模块。 C3K-PWR-1150WAC: 1150WAC 交流电源供应，其中740W PoE C3K-PWR-750WAC: 750WAC交流电源供应，其中370W PoE（支持24端口） C3K-PWR-265WAC: 265WAC交流电源供应（支持48或24端口，无PoE） C3K-PWR-265WDC: 265WDC直流电源供应（支持48或24端口，无PoE）使用思科RPS2300冗余电源模块，可避免内部电源模块失效导致的设备断电，从而为融合的语音数据网络提供最大化的电源保护。使用思科RPS2300冗余电源模块可实现内置电源模块的热插拔交换功能。详细的电源模块兼容性参数，请参见表4。以太网供电如客户要部署了思科的IP电话系统、无线访问点或其它IEEE 802.3af兼容的终端设备，思科 Catalyst 3750-E系列交换机可以提供更低的总体拥有成本。以太网供电技术可免去客户为每个设备部署墙面电源的费用和开销。 思科 Catalyst 3750-E 24端口PoE交换机可为全部24个PoE端口提供最大15.4W电源。 思科 Catalyst 3750-E 48端口PoE交换机提供24端口最大15.4W或48端口最大7.7W电源。 思科 Catalyst 3750-E 48端口PoE交换机使用1150W电源模块可为全部48个PoE端口提供最大15.4W电源。 冗余电源系统思科 Catalyst 3750-E系列交换机支持新一代的RPS2300冗余电源。RPS2300为融合的数据、语音、视频网络提供了更好的冗余供电保护。RPS2300可为2至6台思科 Catalyst 3750-E系列交换机同时提供供电保护，客户可利用该功能为交换机进行失效电源模块更换。主要特性和优势便于使用-即插即用配置一个工作中的堆叠可以自行管理和配置。在用户添加或者移除交换机时，主交换机会自动地更新所有的路由表，及时地反应堆叠结构的变化。升级信息将同时发送给堆叠的所有成员。可扩展性-快速以太网到千兆位以太网Cisco Catalyst 3750-E系列最多可以将9个交换机堆叠在一起，构成一个统一的逻辑单元，其中总共包含468个以太网10/100/1000端口, 432个PoE以太网10/100/1000端口或18个万兆以太端口。各个10/100/1000单元可以根据网络的需要任意组合。混和搭配的交换机类型-根据您扩建网络的速度支付相应的费用可用性-不中断的第二层和第三层性能Cisco Catalyst 3750-E系列可以提高可堆叠交换机的可用性。每个交换机可以充当主控制器和转发处理器。堆叠中的每台交换机都可以充当一个主交换机，从而为网络控制创建了一种1:N的可用性机制。在某个单元发生故障时（尽管发生这种情况的可能性很小），所有其他单元都可以继续转发流量和保持正常运行。高性能-IP路由思科快速转发硬件路由体系提供了非常高性能的IP路由处理能力出色的服务质量-覆盖堆栈和线速Cisco Catalyst 3750-E系列可以提供千兆位以太网速度和智能化的服务，从而可以保持所有数据的平稳传输-即使在十倍于正常网络速度时。业界领先的标记、分类和调度机制可以为数据、语音和视频流量提供业界最佳的性能-全部都以线速提供。安全性-对接入环境的精确控制Cisco Catalyst 3750-E系列支持一组针对连接性和接入控制、全面的安全功能，其中包括ACL、身份认证、端口级安全和基于身份识别的的、支持802.1x及其扩展的网络服务。智能PoE管理支持思科IP电话、无线访问点等IEEE 802.3af兼容终端设备，自动发现、协商、配置端口电源参数、检测端口电源状态变化，并可通过PoE MIB提供可视化的电源使用监视和阀值设定。管理选项Cisco Catalyst 3750-E系列可以提供一个用于精确配置、出色的命令行界面（CLI），此外，CiscoWorks LMS也可以在整个网络范围内对Cisco Catalyst 3750-E系列进行管理。产品参数表2、描述和参数描述参数性能 128-Gbps switching fabric Stack-forwarding rate of 95 Mpps for 64-byte packets Forwarding

the internal power supply or the Cisco RPS 2300. Theconnectors are located at the back of the switch. Internal power supply connector: The internal power supply is an autoranging unit. The internal power supply supports input voltages between 100 and 240VAC. Use the supplied AC power cord to connect the AC power connector to an AC power outlet. Cisco RPS connector: The connector offers connection for an optional Cisco RPS 2300 that uses AC input and supplies DC output to the switch. Only the Cisco RPS 2300 (model PWR2300-AC-RPS-N1=) should be attached to the redundant-power-supplyreceptacle.指示灯 Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications System-status LEDs: system, RPS, and bandwidth-utilization indications尺寸 (HxWxD) 3750E-24TD Inches: 1.75 x 17.5 x 18.1 Centimeters: 4.45 x 44.5 x 46.0 3750E-24PD Inches: 1.75 x 17.5 x 18.1 Centimeters: 4.45 x 44.5 x 46.0 3750E-48TD Inches: 1.75 x 17.5 x 18.1 Centimeters: 4.45 x 44.5 x 46.0 3750E-48PD Inches: 1.75 x 17.5 x 18.1 Centimeters: 4.45 x 44.5 x 46.0 3750E-48PD-F Inches: 1.75 x 17.5 x 21.7 Centimeters: 4.45 x 44.5 x 55.2质量 3750E-24TD Pounds: 17.9 Kilograms: 8.1 3750E-24PD Pounds: 18.3 Kilograms: 8.3 3750E-48TD Pounds: 18.8 Kilograms: 8.6 3750E-48PD Pounds: 19.2 Kilograms: 8.75 3750E-48PD-F Pounds: 20.9 Kilograms: 9.5环境要求 Operating temperature: 32 to 113F (0 to 45C) Storage temperature: -13 to 158F (-25 to 70C) Relative humidity operating: 0 to 95% (noncondensing) Relative humidity nonoperating: 10 to 85% (noncondensing) Operating altitude: up to 10,000 ft (3049 m) Storage altitude: up to 15,000 ft (4573 m)Acoustic Noise International Organization for Standardization (ISO) 7779: bystander position operating to an ambient temperature of30C 3750E-24TD-45 dB 3750E-48TD-45 dB 3750E-24PD-45 dB 3750E-48PD-45 dB 3750E-48PD-F-48 dB平均无故障工作时间(MTBF)3750E-24TD-177,975 hours3750E-24PD-167,107 hours3750E-48TD-166,369 hours3750E-48PD-153,265 hours3750E-48PD-F-149,667 hours表3、管理和标准描述参数管理 BRIDGE-MIB CISCO-CDP-MIB CISCO-CLUSTER-MIB CISCO-CONFIG-MAN-MIB CISCO-ENTITY-FRU-CONTROL-MIB CISCO-ENVMON-MIB CISCO-FLASH-MIB CISCO-FTP-CLIENT-MIB CISCO-HSRP-MIB CISCO-HSRP-EXT-MIB CISCO-IGMP-FILTER-MIB CISCO-IMAGE-MIB CISCO-IP-STAT-MIB CISCO-L2L3-INTERFACE-CONFIG-MIB CISCO-POE-EXTENSIONS-MIB CISCO-MAC-NOTIFICATION-MIB CISCO-MEMORY-POOL-MIB CISCO-PAGP-MIB CISCO-PING-MIB CISCO-PROCESS-MIB CISCO-RTTMON-MIB CISCO-STP-EXTENSIONS-MIB CISCO-SYSLOG-MIB CISCO-TCP-MIB CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB CISCO-VLAN-MEMBERSHIP-MIB CISCO-VTP-MIB ENTITY-MIB ETHERLIKE-MIB IF-MIB IGMP-MIB IPMROUTE-MIB OLD-CISCO-CHASSIS-MIB OLD-CISCO-FLASH-MIB OLD-CISCO-INTERFACES-MIB OLD-CISCO-IP-MIB OLD-CISCO-SYS-MIB OLD-CISCO-TCP-MIB OLD-CISCO-TS-MIB OSPF-MIB (RFC 1253) PIM-MIB RFC1213-MIB RFC1253-MIB RMON-MIB RMON2-MIB SNMP-FRAMEWORK-MIB SNMP-MPD-MIB SNMP-NOTIFICATION-MIB SNMP-TARGET-MIB SNMPv2-MIB TCP-MIB UDP-MIB标准 IEEE 802.1s IEEE 802.1w IEEE 802.1x IEEE 802.3ad IEEE 802.3af IEEE 802.3x full duplex on 10BASE-T, 100BASE-TX, and 1000BASE-T ports IEEE 802.1D Spanning Tree Protocol IEEE 802.1p CoS Prioritization IEEE 802.1Q VLAN IEEE 802.3 10BASE-T specification IEEE 802.3u 100BASE-TX specification IEEE 802.3ab 1000BASE-T specification IEEE 802.3z 1000BASE-X specification 100BASE-FX 1000BASE-T 1000BASE-SX 1000BASE-LX/LH 1000BASE-BX10-U 1000BASE-BX10-D 1000BASE-ZX 1000BASE-CWDM SFP 1470 nm 1000BASE-CWDM SFP 1490 nm 1000BASE-CWDM SFP 1510 nm 1000BASE-CWDM SFP 1530 nm 1000BASE-CWDM SFP 1550 nm 1000BASE-CWDM SFP 1570 nm 1000BASE-CWDM SFP 1590 nm 1000BASE-CWDM SFP 1610 nm 10GBASE-SR 10GBASE-LR 10GBASE-ER RMON I and II standards SNMPv1, SNMPv2c, and SNMPv3表4、电源供应兼容性矩阵Cisco Catalyst 3750-E Series Switch Type电源模块C3K-PWR-1150WACC3K-PWR-750WACC3K-PWR-265WACC3K-PWR-265WDC48-Port PoE SwitchXX24-Port PoE SwitchXX48-Port SwitchXXXX24-Port SwitchXXXXRPS 2300XX表5、供电参数描述参数C3K-PWR-1150WACC3K-PWR-750WACC3K-PWR-265WACC3K-PWR-265WDCMax Output Power1150W750W265W265WInput-Voltage Range and Frequency115-240VAC,50-60 Hz100-240VAC,50-60 Hz100-240VAC,50-60 Hz-36VDC to -72VDCInput Current12-6A10-5A5-2.5A5A-72VDC 2ms-48VDCPower-Supply Input ReceptaclesIEC 320-C13(IEC60320-C19)IEC 320-C13(IEC60320-C13)IEC 320-C13(IEC60320-C13)Power Cord Rating15A15A15A12A-100VDC表6、电源模块参数产品参数电源模块C3K-PWR-1150WACC3K-PWR-750WACC3K-PWR-265WACC3K-PWR-265WDC物理参数(H x W x D): 1.65 X 6.0 X 14.90 inWeight: 5.6 lb(2.6 kg)(H x W x D): 1.65 X 6.0 X 11.4 inWeight: 3.9 lb(1.8 kg)(H x W x D): 1.65 X 6.0 X 11.4 inWeight: 3.3 lb(1.5 kg)(H x W x D): 1.65 X 6.0 X 11.4 inWeight: 3.5 lb(1.6 kg)合计输入BTU (Note: 1000 BTU/hr = 290W)3924 BTU/hr, 1150W4225 BTU/hr, 765W920BTU/hr, 265W920BTU/hr, 265W工作温度范围23 to 113F (-5 to 45C)储存温度范围-40 to 158F (-40 to 70C)工作湿度范围10 to 85% noncondensing储存湿度范围0 to 95% noncondensing海拔高度10,000 ft.
