2 I NSTALLING THE S WITCH This chapter contains the informat ion you need to install and set up the Switch 4200 Series. It covers the following topics: ■ Package Contents ■ Choosing a Suitable Site ■ Rack-mounting ■ Placing Units On T op of Each Other ■ The Power -up Sequence ■ GBIC Operation WARNING: Safety Information.
20 C HAPTER 2: I NSTALLING THE S WITCH Package Contents ■ Switch unit ■ CD-ROM ■ Getting Started Guide (this guide) ■ Management Quick Reference Guide ■ Release No tes ■ Unit Information L.
Rack-mount ing 21 ■ The air is as free fr om dust as possible. ■ The switch is situated away from sources of conductive (electrical) dust, for example, laser printers.
22 C HAPTER 2: I NSTALLING THE S WITCH Figure 5 Fitting a bracket for rack-mounting 3 Insert the two screws and tighten with a suitable screwdriver . Y ou must use the screws supplied w ith the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty .
Placing Units On Top of Each Other 23 Placing Units On T op of Each Other If the Switch units ar e free-standing, up to eight units can be placed one on top of the other . If you ar e mixing a variety of SuperStack ® 3 Switch and Hub units, the smaller units must be positioned at the top.
24 C HAPTER 2: I NSTALLING THE S WITCH When another Switch 4200 Series unit is added to the top of an established stack, no stack renumbering occurs. If however the unit being added takes the stack height above 4 then the ‘u p’ port on the top unit of the existing stack will be disabled and its LED will flash green.
The Power-up Sequence 25 Ta b l e 6 Power/Self T est LED colors In addition, check the Unit LEDs on all Switches in the stack. If a Unit LED is off, initialization is not complete . 3Com r e commends that you do not use the Switch's management interface until the Unit LED is green.
26 C HAPTER 2: I NSTALLING THE S WITCH port, you need a cross-over cable. Many ports on workstatio ns and servers are configur ed as MDI (straight-through). If you want to make a connection to an MDI port, you need to use a standard straight-thro ugh cable.
GBIC Operation 27 GBIC Operation The following section describes how to insert a GBIC transceiver into a GBIC port. This section applies to the SuperStack 3 Switch 4228G on ly . GBIC transce ivers are hot -insertable an d hot-swappa ble. Y ou can remove them from and insert them into any GBIC po rt without having to power down the Switch.
28 C HAPTER 2: I NSTALLING THE S WITCH Use this transceiver to connect the Switch directly to a single-mode fiber - optic cable or to mult imode fiber using a con ditioned launch cable.

3 S ETTING U P FOR M ANAGEMENT Y our Switch can operate in its default state, that is, you can install it and it will work straight away (plug-and- play). However , to make full use of the features of fered by the Switch, and to change and monito r the way it works, you have to acce ss the management software that r esides on th e Switch.
32 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Setting Up Overview This section gives an overview of what you need to do to g et your Switch set up and rea dy for manage ment when it is in its default state. The whole setup process is summarised in Figur e 8 .
Setting Up Overview 33 IP Configuration Y ou can use one of the following meth ods to allocate IP information to your Switch (essential if you wish to manage your Switch across the network). Manual IP Configuration Y ou can choose to config ure the IP information yourself.
34 C HAPTER 3: S ETTING U P FOR M ANAGEMENT However , as soon as a DHCP or BootP se rver is detected, the Switch will configure itself with the IP address allocated by that server .
Manually Configuring IP Informatio n 35 Manually Configuring IP Information Y ou can man ually configure the Switch IP information in the following ways: ■ Connecting to a front panel port — Connect a works tation using an Ether net cable to a front panel port of the Switch.
36 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Connecting the W orkstat ion to the Switch 1 Connect the workstation to a front panel port using an Ethernet cable as shown in Figure 9 .
Manually Configuring IP Informatio n 37 If there is no response, wait for one minute then re-enter the default IP address. 3 At the login and password prompts, enter admin as your user name and press Return at the p assword pr ompt (default user n ame and pass word).
38 C HAPTER 3: S ETTING U P FOR M ANAGEMENT top-level menu of the co mmand line i nterface is displayed as shown in the example in Figure 10 . Figure 10 Example top-level command line interface menu 4 At the Select menu option prompt you can either: ■ enter the protocol ip basicConfig command.
Manually Configuring IP Informatio n 39 Pre-r equisites ■ A workstation with terminal emulation soft ware installed, such as Microsoft Hyperterminal. This software allows you to communicate with the Switch via the console port directly , or through a modem.
40 C HAPTER 3: S ETTING U P FOR M ANAGEMENT 2 Open your terminal emulation software and configure the COM port settings to which you have connected the cable.
Manually Configuring IP Informatio n 41 Figure 12 Example top-level command line interface menu 3 At the Select menu option prompt you can either: ■ enter the protocol ip basicConfig command. At the Enter configuration method prompt enter manual . The screen prom pts you to e nter IP in formation.
42 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Viewing Automatically Configured IP Information If you allow the Switch to automatica lly configure its own IP information you need to discover and view the IP information before you can begin to manage the Switch.
Viewing Automaticall y Configured IP Informatio n 43 ■ A suitable cable: ■ A standard null modem cable — if you ar e connecting directly to the console port, or ■ A standard modem cable — if y ou are connecting to the console port using a modem.
44 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Viewing IP Information via the Console Port Y ou are now r eady to view the auto matically allocate d IP information using the command line interface. 1 Connect your Switch to the network using an Ether net cable.
Methods of Managing a Switch 45 pr ompt en ter all . A summary of the automatically allocated IP information is displayed. Make a note of the Network IP Ad dre ss. The initial set up of your Switch is now complete and the Switch is r e ady for you to set up your chosen man agement method.
