Installing the Wireless Bridge Manager Software If any of these items is missing or damaged, please contact the place of purchase or 3Com Customer Support (http://support.3com.com). Installing the Wireless Bridge Manager Software You can install the 3Com Wireless Building-to-Building Bridge Manager on a PC or workstation running Windows 95, 98, Me, Windows 2000, or Windows NT.
Quick Start Guide Configuring the Wireless Bridge Units The 3Com Wireless Building-to-Building Bridge Manager software communicates with each wireless bridge using a non-routable protocol. Therefore, your wireless bridge units must be accessible on the local subnet to communicate with the Bridge Manager. CAUTION: Do not try to batch-configure a set of wireless bridge units by powering up all of your units and connecting them to the same subnet at the same time.
Configuring the Wireless Bridge Units 3 Insert one end of the RJ-45 crossover cable into the bridge 10BASE-T Ethernet port 3 . Insert the other end of the cable into the appropriate port on your Ethernet LAN device (a hub, for example). Starting the Bridge Manager To run the Wireless Bridge Manager, follow these steps: 1 On the Windows taskbar, click Start. 2 Select Programs and then select the Program Group you created when you installed the Wireless Bridge Manager.
Quick Start Guide Setting Network and Security Values You can change network and security settings for the wireless bridge in the Network / Security tab of the Wireless Bridge Configuration screen. Network Values Network settings determine the wireless network with which the bridge can associate. To change the Network / Security tab settings: 1 Enter the name of a WLAN Service Area. The WLAN service area (ESSID) is used to specify a unique wireless network.
Configuring the Wireless Bridge Units 2 Use the Security Setting pull-down menu to select one of the following security settings: ■ No Security (Open System) ■ 40-bit Shared Key for basic encryption ■ 128-bit Shared Key for strong encryption Using either a 40-bit or 120-bit shared key setting, all wireless bridge units in a single wireless LAN service area must share the same security key. The security settings for any associating bridge pair must match exactly.
Quick Start Guide Security Settings 3Com recommends using the strongest encryption setting supported by your wireless bridge. The Bridge Manager offers 128-bit (strong) or 40-bit (basic) shared-key encryption; however, 128-bit encryption may not be available to you, depending on U.S. export restrictions to your country. Both strong and basic encryption make use of Wired Equivalent Protection (WEP) keys, which are expressed in hexadecimal notation.
Configuring the Wireless Bridge Units 3 Select Specify Encryption String. 4 Type the encryption string in the Encryption String field. Retype the encryption string in the Confirm Encryption String field to make sure that you have entered the string correctly. 5 Click OK when finished.
Quick Start Guide Entering the Encryption Keys You can decline to enter an encryption string and instead manually enter the WEP keys. To manually enter the WEP keys in hexadecimal notation, follow these steps: 1 In the Network / Security tab of the Wireless Bridge Configuration screen, select either 128-bit Shared Key or 40-bit Shared Key from the Security setting list. 2 Click Encryption Key Settings. The appropriate Encryption Key Settings screen appears. 3 Select Specify Encryption Keys.
Mounting the Wireless Bridge Mounting the Wireless Bridge Mounting a wireless bridge unit is optional. If desired, you can simply leave the unit standing freely on a table surface. Whether to mount the unit on a wall or ceiling will usually depend on the length of the cable extending from the bridge unit to the antenna. 1 Detach all cables from the wireless bridge so that you can safely and easily mount the unit. 2 Remove the bottom mounting plate, as shown in the following figure.
Quick Start Guide To fine-tune the position of a particular antenna, it can be helpful to use a mobile PC loaded with the Wireless Bridge Manager so that you can use a diagnostic tool, the RSSI monitor, to adjust the angle and direction of the antenna at the antenna site. Perform the following steps for each wireless bridge antenna: 1 Mount the antenna within cable distance (50 ft. max.) of the wireless bridge. Refer to the user guide for detailed information about properly positioning your antenna.
