Rack-mount ing 21 ■ The switch is situated away from sources of conductive (electrical) dust, for example, laser printers. ■ The unit is installed in a clean, air conditioned environment.
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 s upplied with 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 are 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 Stack renumbering occurs when another Switch 4200 Family unit is added to the bottom of an established stack except when the stack is already 4 units high. In this instance the ‘down’ port on the bottom unit of the existing stack will be disabled and its LED will flash green.
The Power-up Sequence 25 When the POST has complete d, check the Power On Se lf Te s t L E D t o make sure that your Switch is oper ating correctly . Ta b l e 6 shows possible colors for the LED. Ta b l e 6 Power/Self T est L ED colors In addition, check the Unit LEDs on all Switches in the stack.
26 C HAPTER 2: I NSTALLING THE S WITCH If auto-negotiation is disabled, all the Switch ports ar e configur ed as MDIX (cross-over). If you want to make a connection to another MDIX port, you need a cross-over cable. Many ports on workstatio ns and servers are configur ed as MDI (straight-through).
GBIC Operation 27 If you wish to connect a 1000BASE-SX MT -RJ port to a fiber port with a different type of connector , for exampl e, SC or ST please contact your network supplier for a suitable patch cable. GBIC Operation The following section describes how to insert a GBIC transceiver into a GBIC port.

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 monitor th e way it works, you have to acce ss the management software that r esides on the 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 get your Switch set up and r eady for man agement when it is in i ts default stat e. 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 choo se to configure 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 workstat ion 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 name and password).
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 th e 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 th e protocol ip basicConfig command. At the Enter configuration method prompt enter manual . The screen prompts you to enter IP information.
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 ready to vi ew 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 eady for you to set up your chosen management method.
