Cisco设备选型

  Catalyst 6506光模块分析
  基于SFP的1000BASE-T端口:RJ-45连接器;两对5类UTP电缆
  基于SFP的1000BASE-SX、-LX/LH、-ZX和CWDM 端口:LC光纤连接器(单模或多模光纤)
  GBIC
  1000M电口模块WS-G5483
  The WS-G5483 GBIC, shown in Figure 2-14, uses Category 5 UTP/FTP cable to provide 1000BASE-T full-duplex connectivity between the Ethernet module or supervisor engine and the network up to a distance of 328 feet (100 m).

  WS-G5487 1000Base-ZX extended reach GBIC(singlemode)
  SFP
  1000M电口模块GLC-T
  The 1000BASE-T (GLC-T) SFP module is compliant with IEEE 802.3:2000 and plugs into a standard Gigabit Ethernet SFP module port. It operates on standard Category 5 wiring and has an RJ-45 connector.

  GLC-SX-MM
  Long Wavelength Modules
  GLC-LH-SM
  Extended Wavelength Modules
  GLC-ZX-SM
  SFP and GBIC Short Wavelength Modules
  The 1000BASE-SX (short wavelength) GBIC module operates on standard multimode fiber-optic link spans of up to 1804 feet (550 m).
  SFP and GBIC Long Wavelength Modules
  The 1000BASE-LX/LH (long wavelength/long haul) GBIC module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles (10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.
  SFP and GBIC Extended Wavelength Modules
  The 1000BASE-ZX (extended wavelength) GBIC module operates on ordinary single-mode fiber-optic link spans of up to 43.5 miles (70 km).
  常用模块:
  WS-X6748-SFP Catalyst 6500 48-port GigE Mod: fabric-enabled (Req. SFPs)
  光纤MOD,需要另外选配SFP
  WS-X6748-GE-TX Cat6500 48-port 10/100/1000 GE Mod: fabric enabled, RJ-45
  WS-X6148A-GE-45AF
  Cat6500 48-Port PoE+ ready 10/100/1000 w/Jumbo Frame
  主要用于VOIP环境
  Cisco3845设备选型
  对于数据E1,可以用选配以下三种模块:
  -1).HWIC-2T
  HWIC-2T 2-Port Serial WAN Interface Card 2
  CAB-ACA AC Power Cord (China/Australia), C13, AS 3112, 2.5m 1
  CAB-SS-V35MT V.35 Cable, DTE Male to Smart Serial, 10 Feet 2
  注意:
  如果是HWIC-2T,则选配CAB-SS-V35MT(Smart Serial,小串口),一条E1,则CAB-SS-V35MT * 1;两条E1,则CAB-SS-V35MT * 2
  如果是HWIC-1T,则选配CAB-V35MT(大串口),一条E1对应一根CAB-V35MT
  参见<<Cisco模块和线缆速查表>>
  如果客户希望2M进行时隙划分,推荐使用VWIC-2MFT-G703,它可以工作在成帧(分时隙)模式,也可以工作在非成帧(2M净通道)模式
  -2).VWIC2-2MFT-T1/E1
  VWIC2-2MFT-T1/E1 2-Port 2nd Gen Multiflex Trunk Voice/WANInt. Card - T1/E1 1
  CAB-E1-RJ45BNC E1 Cable RJ45 to Dual BNC (Unbalanced) 1
  注意:
  VWIC2-2MFT-T1/E1比HWIC-2T价格贵,但是可以承载语音载荷
  如果是VOICE线路,推荐用这种卡。接口有RJ48(RJ45)和BNC两种,项目中需要先跟Teleco协商:如果是电口,就可以用网线互联;如果是BNC口,则用同轴电缆互联
  VWIC2-2MFT-T1/E1插入路由器以后默认不会激活,需要输入以下命令激活:
  card-type e1/t1 0/0
  -3).可以分TS的E1模块价格更高
  HWIC-2CE1T1-PRI
  2 port channelized T1/E1, and PRI HWIC (data only)
  channelized voice E1 card?
  -4).一般配备一根电缆(如客户要求电源冗余,则配置两个电源模块和2根电缆):
  PWR-3845-AC Cisco 3845 AC power supply 1
  CAB-ACA AC Power Cord (China/Australia), C13, AS 3112, 2.5m 1
  -5).如何为Cisco3845选配以太网模块
  在Dynamical Configuration Tools里可以看到有三种模块可供选择,区别如下
  HWIC-4ESW(425$) PUG approved
  Four port 10/100 Ethernet switch interface card
  这个最便宜,先将将端口分配到vlan,然后在Layer3 SVI上创建三层连接。HWIC-4ESW一共有4个ports,每个port放到一个vlan,所以我们可以得到4个三层连接端口。
  关于它的routing capability,可以参看下边的帖子
  https://supportforums.cisco.com/message/113645#113645
  https://supportforums.cisco.com/message/799011#799011
  注意:HWIC-4ESW虽然可以实现三层连接,但是不能用它来做WAN连接,如果是和ISP对接,则需要选用下边的两种模块:
  HWIC-2FE(1450$)
  Two 10/100 routed port HWIC
  FastEthernet,路由端口,天生就是拿来跑IGP的!
  NM-2FE2W-V2(3200$)
  2 port 10/100 Ethernet with 2 WAN Card Slot Network Module
  用起来和HWIC-2FE差不多,都能实现三层连接,但是价钱贵了不少,不知道Cisco推这个东东干嘛用的

  -6).如何选配E3/DS3模块
  一般有两种模块可供选择
NM-1T3/E3(8,500$)One port T3/E3 network moduleclear T3/E3 channel,无需专门的cable,模块上的BNC头可以跟ISP的E1线缆直接对接。下边的帖子有专门的论述:https://supportforums.cisco.com/thread/211196;jsessionid=687CD3202DD2E68B20E0AF968EF68E7A.node0?tstart=3CAB-ATM-DS3/E3ATM Cable, DS-3 and E3, 10NM-1A-T3/E3(6,000$)1-Port T3/E3 ATM network Module  ATM encapsulated E3,需要选配专门的cable
  选配什么样的E3模块,建议提前和ISP沟通

  -7). 韩国和香港用什么power cable
  韩国:European plug, CAB-ACE.
