To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings。
Warning：When installing the unit, the ground connection must always bemade first And disconnected last.1.2 在机架上固定交换机l Attaching Brackets (Front Panel Forward)l Attaching Brackets (Rear Panel Forward)l Mounting the Switch in a Rackl Attaching the Optional Cable Guide1.3 安装GBIC模块l Installing a 1000BASE-X GBIC Module in the Switchl Installing a 1000BASE-T GBIC Module in the Switchl Installing a GigaStack GBIC Module in the Switch1.4 安装连接线缆注意：交换机端口速率、双工的设置Ø Let the ports autonegotiate both speed and duplex.Ø Set the port speed and duplex parameters on both ends of the connection.When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through Category 5 cable to an RJ-45 connector on the front panel.When connecting to switches or repeaters, use a crossover Category 5 cable。
l Connecting to a 10/100/1000 Switch PortThe port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This takes about 30 seconds, and then the port LED turns green.If the port LED does not come on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device.l Connecting to a 1000BASE-X PortCaution ： Do not remove the rubber plugs from the fiber-optic port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the fiber-optic port and cable from contamination and ambient light.l Connecting to a 1000BASE-T Portl Connecting to a GigaStack Portl Connecting to the Console PortAttach the supplied RJ-45-to-DB-9 female DTE adapter to a PC, or attach an appropriate adapter to the terminal.Insert the other end of the supplied rollover cable in the attached adapter.Boot the terminal-emulation program if you are using a PC or terminal.第二部分交换机基本配置CISCO2950-24/48 EI 交换机配置涉及到加电后首次配置、通过浏览器进行配置以及通常的基于CLI命令行配置等方面。
2.1 加电后首次配置Use the supplied rollover cable and DB-9 adapter to connect a PC to the switch console port. If you want to connect the switch console port to a terminal, you need to provide a RJ-45-to-DB-25 female DTE adapter.The PC or terminal must support VT100 terminal emulation. The terminal-emulation software—frequently a PC application such as Hyperterminal or Procomm Plus—makes communication between the switch and your PC or terminal possible during the setup program.Configure the baud rate and character format of the PC or terminal to match these console port default characteristics:Ø 9600 baudØ 8 data bitsØ 1 stop bitØ No parityUsing the supplied rollover cable, insert the RJ-45 connector into the console port。
Note：If the switch will be a cluster member managed through the IP address of the command switch, it is not necessary to assign IP information or a password. If you are configuring the switch as a standalone switch or as a command switch, you must assign IP information.Would you like to enter the initial configuration dialog? [yes/no]: yesWould you like to enter basic management setup? [yes/no]: yesEnter host name [Switch]: xxxxOn a command switch, the host name is limited to 28 characters; on a member switch to 31 characters. Do not use -n, where n is a number, as the last character in a host name for any switch. Enter enable secret: xxxxThe password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spacesEnter enable secret: xxxxEnter virtual terminal password: xxxxEnter interface name used to connect to the management network from the above interface summary: vlan 1Configuring interface vlan 1:Configure IP on this interface? [yes]: yesIP address for this interface: xxxxSubnet mask for this interface [255.0.0.0]: xxxxWould you like to enable as a cluster command switch? [yes/no]: 视具体情况定，一般，一个堆叠中仅有一台交换机需要配置为命令交换机Enter cluster name: xxxxThe cluster name can be 1 to 31 alphanumeric characters, dashes, or underscores.2.2 通过浏览器配置交换机例如，通过CMS可以方便的配置集群，方便全网连入集群的交换机的管理。
