2. Quick Installation You may follow the quick installation steps if the following conditions are true: ❑ There will only be one RangeLAN2 7500 on this network ❑ You will use all the software default values (MASTER, domain 0, IP address 192.0.1.2) ❑ You will not be setting security IDs on your network ❑ All RangeLAN2 computers are configured as STATIONs or ALTERNATE MASTERs If your installation meets the preceding criteria, proceed with the following instructions: 1.
Figure 2 Attachment of the RangeLAN2 7500 Antenna 3. Attach an Ethernet cable to the Ethernet port on the back of the RangeLAN2 7500. 4. Plug the power cable into the back of the RangeLAN2 7500 and into an AC power outlet. 5. Turn the RangeLAN2 7500 on. The power switch can be found on the back of the bridge. 6. Watch the floppy drive LED to see that the disk is being accessed when power is applied. 7. Install the floppy drive cover.
3. Network Topologies Network operating system consist of servers and clients. Servers store the information and clients access it. The way these computers are configured and communicate depends on the type of network operating system. Client/Server Network Operating Systems In a client/server network operating system, one machine is the dedicated file server. Typically, it cannot be used for any other functions while acting as the file server. NetWare is an example of a client/server operating system.
Peer-to-Peer Network Operating Systems In a peer-to-peer network operating system, each machine can be configured as both a server and a client. Servers are typically non-dedicated and can, therefore, be used as someone's desktop machine. In the peer-to-peer environment, all stations can communicate with all other stations directly provided they have the same cabling type. In the wireless arena, this means that all wireless stations can talk to all other wireless stations.
4. Understanding RangeLAN2 RangeLAN2 radios use a radio technology called frequency hopping spread spectrum. This means that the radio signal is constantly moving from one frequency to another while sending packets of data. This hopping technique allows for multiple hopping patterns to be used in the same area and minimizes interference. RangeLAN2 Software Parameters default=2 Station_Type In order for this system to work, in each subnetwork there must be one unit that coordinates the hops.
There must be at least one station on the network designated the Master station. For most network operating systems, the RangeLAN2 7100 card in the server or RangeLAN2 7500 should be the Master and all clients are defined as Stations. In a roaming environment, all RangeLAN2 7500 Access Points will be configured as Masters. The RangeLAN2 7100 and RangeLAN2 7200 clients are all configured as Stations and roam from one Master to another.
The Domain is a number between 0 and 15 with 0 being the default setting. default=1 Channel Each Master can select one of 15 Channels to establish communications with Stations. Each Channel number sets a unique frequency hopping sequence allowing for multiple subnetworks with higher data rate transmission capability in the same air space. You may think of the Channel as a pipe.
For example, you can use Channel 1, Subchannel 1 for Network A and Channel 1, Subchannel 2 for Network B. The two networks will not communicate with one another. They are, however, still sharing the 1.6 Mbps pipe since they are both using Channel 1. The Subchannels are designated 1 through 15 with 1 being the default setting. You need only set the Subchannel on a Master or Alternate Master. Stations will ignore the parameter if it is set.
default=1 MAC_Optimize This parameter can help improve throughput for small networks. If you have 8 or fewer wireless nodes communicating with a RangeLAN2 7500 at the same time, set this parameter to Light. (You can have more than 8 nodes synchronized to a RangeLAN2 7500 but only 8 or fewer communicating at the same time for the Light parameter setting.) In networks with more than 8 concurrent wireless users, set the parameter to Normal.
You need only set the Roam_Config parameter on a Station or Alternate Master. Masters will ignore the parameter if it is set. The Roam_Config settings are as follows: ❑ Slow =0 ❑ Normal =1 ❑ Fast =2 RangeLAN2 Roaming In order to enhance our wireless solutions, Proxim offers roaming capability to break the wireless distance barrier. To accomplish this, install RangeLAN2 7500 Access Points throughout your building.
The user can move freely between the RangeLAN2 7500 Access Points in the network. When the roaming PC leaves the transmission range of one RangeLAN2 7500, the software automatically polls the other RangeLAN2 7500 in the same Domain to continue the network connection. See the following illustration for an example of a network set up with a RangeLAN2 roaming domain. Note that the cells must overlap to ensure that there are no gaps in coverage, and that the roaming PC will always have a connection available.

Guidelines for Roaming ❑ Roaming occurs between RangeLAN2 7500 Access Points (not RangeLAN2 7100s in file servers) ❑ All RangeLAN2 7500s are configured as Masters ❑ All RangeLAN2 7500s have the same Domain and Security ID ❑ All RangeLAN2 7500s have a unique Channel/ Subchannel pair. Preferably, they should have unique Channels. Only use the Subchannel once you have used all 15 Channels in the same coverage area.
Spanning Tree Protocol Support RangeLAN2 7500 meets the IEEE 802.1d Spanning Tree Protocol specification. This protocol was designed to handle cases in a complex bridged network (multiple bridges) where loops are created either unintentionally or to provide redundancy in the network. The bridges will configure themselves into a spanning tree topology removing any loops within the network.
The network's bridges determine who should become inactive based on several parameters which you may configure on RangeLAN2 7500 using the configuration program CFG.EXE or a network management station which supports the IEEE 802.1d Bridge MIB (RFC 1493). Spanning Tree Priority This parameter sets the priority of RangeLAN2 7500 in the spanning tree created on the network.
Bridge Forward Delay This parameter specifies the amount of time it takes to transition between port states after reset of the RangeLAN2 7500. The state transitions are as follows: disabled; blocking incoming packets; listening for other bridges; learning the addresses of other bridges; and forwarding data. It is specified in seconds between 4 and 30 with a default setting of 15. Aging Time This parameter specifies the time after which the learned physical address of the network node is discarded.
RangeLAN2 Port Path Cost and Ethernet Port Path Cost These parameters specify the cost that will be added to the spanning tree for this port of the RangeLAN2 7500. This applies only when the RangeLAN2 7500 is not the root of the tree and when the port you are setting is the root port of the 2 RangeLAN2 7500 ports. The parameter range is 1 to 65535 with a default value of 100 for the Ethernet port and 625 for the RangeLAN2 port.

1. Connect the null modem RS-232 cable between the RangeLAN2 7500 Local Management Port and a free serial port on your PC. 2. If you are running the CFG tool from a DOS prompt in Windows, load WINPKT.COM before entering Windows using the command: C:\> WINPKT 0X60 3. Copy the software from the RangeLAN2 7500 Configuration Tool diskette to a directory on your PC's hard disk. C:\AP> COPY A:*.* (or B:) 4. One of the files you copied is a batch file called SLIP.BAT.
where and refer to the Interrupt and I/O Port Address of the COM port: Port COM1 COM2 COM3 COM4 4 3 4 3 0x3F8 0x2F8 0x3E8 0x2E8 For example, if your PC's available serial port is COM1, the batch file would look like: SLIP8250 0x60 SLIP 4 0x3F8 9600 5. Move to the directory which contains the batch file and the RangeLAN2 7500 Configuration Software and run the batch file: C:\> CD\AP C:\AP> SLIP 6.
7. Choose Local Access Point and press
C:\> WINPKT 0X61 3. Copy the software from the RangeLAN2 7500 Configuration Tool diskette to a directory on your PC's hard disk. C:\AP> COPY A:*.* (or B:) 4. Edit the CFG.CFG file. This file assigns an IP address to the machine being used to configure the RangeLAN2 7500. If this is the first time you are configuring the RangeLAN2 7500, leave the default setting in CFG.CFG. Once the RangeLAN2 7500 has been assigned an IP address, re-edit the CFG.
5. Load a packet driver for your Ethernet card. A packet driver usually has parameters that are set on the driver load line. It does not require LSL or a NET.CFG configuration file like an ODI driver does. Skip to step 8. Alternatively, you may use the Ethernet card's ODI driver rather than a packet driver. In this case, proceed with step 6. 6. To use the Ethernet card's ODI driver, copy this driver into the same directory as the RangeLAN2 7500 Configuration Software. 6. Edit the NET.
C:\AP> LSL C:\AP> ETHDRVR C:\AP> ODIPKT 9. Start the configuration software: C:\AP> CFG 10. Choose Default from the list of Access Points if this is an initial configuration and press
Note: You may not run IP protocol stacks while the CFG program is loaded. You may run non-IP protocol stacks while the configuration software program is loaded. In order to do this, you will need to create entries for those stacks in the NET.CFG file and bind to the proper frame type. Using an SNMP Management Package You may choose to manage the RangeLAN2 7500 by any SNMP management package. The RangeLAN2 7500 supports the following managed objects: ❑ MIB-II (RFC 1213) ❑ IEEE 802.
You may choose to configure the RangeLAN2 7500 through the Configuration Tool (in-band or out-of-band) to set SNMP parameters before using an SNMP manager. Choose the button labeled . System Description names the RangeLAN2 7500 you are managing and displays the version of software it is running. This field is not editable. System Uptime shows the amount of time since the system was last initialized. This field is not editable.
The Read-Only Community parameter specifies a community supported by the RangeLAN2 7500. Actions permitted by this community are “read-only.” Only GET and GET-NEXT operations are supported within the scope of this community. SET attempts using this community will result in rejection of the attempt with a general error response and the generation of an authentication trap (if so enabled). The Read-Write Community parameter specifies the a community supported by the RangeLAN2 7500.
Authorization - Sent to the network manager when someone tries to manage a RangeLAN2 7500 with an invalid community No Traffic - Sent when set to a non-zero value and when the RangeLAN2 7500 does not receive any traffic from other radios for the configured period of time. The time may be configured in the screen.

6. Using the Configuration Software At any point in the configuration software, you can use either a mouse or keyboard to make selections. If using a keyboard, press followed by the highlighted letter to make a selection. Pressing the key cycles through the buttons displayed. Pressing the key displays information about the parameters you are setting. You may use the CFG program to either locally or remotely manage the RangeLAN2 7500.
The button allows you to change all radio options including Station_Type, Master_Name, Channel, Subchannel, Security ID, etc. The No Traffic Warn Interval field specifies the amount of time that must elapse with no traffic before a trap is sent to the configured “Trap Target.” You also have the option to enable or disable repeating.
If you have multiple RangeLAN2 7500s on your network and want to give wireless clients roaming capabilities, all RangeLAN2 7500s should be configured as Masters in the same Domain with unique Channel/Subchannel combinations. For more information on the RangeLAN2 software parameters, see chapter 4. Configure Bridge The button is used if you have other kinds of bridges on your network and will be relying on the Spanning Tree Algorithm.
You also have the option to enable or disable spanning tree support. If you have no other bridges on the network, or you have some method other than the IEEE 802.1d Spanning Tree Protocol to prevent loops on the network, you can choose to disable this feature. Configure TCP/IP The button is used to change the IP address, Subnet Mask, and Default Gateway of the RangeLAN2 7500.
IP Address indicates the IP address that will be assigned to the RangeLAN2 7500. It must be a unique number on the network. Subnet Mask indicates the mask that will be used to determine what network the RangeLAN2 7500 is on. If a packet is destined for an IP host or node that needs to cross a router, the RangeLAN2 7500 will look for the Default Gateway to indicate where a router is that can send the packet to its proper destination.
Configure Filters The filter configuration allows you to customize the type of traffic which is forwarded from the Ethernet network to the RangeLAN2 network. When a box is checked, this indicates that traffic that meets the corresponding filter characteristic (e.g., Protocol Type) will be filtered OUT, and will NOT be forwarded.
The PROTOCOL TYPE FILTERS prevent traffic of a particular protocol type from being forwarded from Ethernet to RangeLAN2. When “Other Types” is checked, all types other than those listed will be filtered out. DO NOT filter out the types of packets you know RangeLAN2 nodes will need to receive. For example, if you use TCP/IP as a protocol on your network, do not filter IP/ARP traffic.

7. Performance Hints This section gives the user some ideas as to how to increase performance and network satisfaction on a wireless network. Running Large Executable Files Efficiently You may notice that certain executable files like Novell's LOGIN program can take a long time to start up. You can make this more efficient if you copy the file to your local hard disk. This way the server is only accessed to read data files, which will allow for better performance.
This configuration leaves the system administrator for the network with the task of configuring each wireless station on the network as Master station, Alternate Master station or just a Station. In most cases, using the default configurations for each of the drivers will work fine. But there may be times when the administrator wants to change the configuration for performance, or other issues. Here are several factors to consider: 1.
Microwave Ovens Microwave ovens operate in the same frequency band as RangeLAN2. Therefore, if you use a microwave within range of RangeLAN2 you may notice network performance degradation. However, both your microwave and your RangeLAN2 network will continue to function. Range Every environment is unique with different obstacles, barriers, materials, etc. and therefore, it is difficult to determine the exact range that will be achieved with testing.
Proper antenna placement can help improve range. Here are some guidelines: ❑ The antenna should be placed in a vertical position. It can be mounted upside down to the ceiling or beam. ❑ Place the antenna as high as possible. In an office environment, try to place it above cubicle walls. ❑ Do not place a sheet of metal (like a filing cabinet) between two antennas. ❑ Two antennas that are communicating should be in the same plane.
8. Troubleshooting RangeLAN2 7500 is designed to be very easy to install and operate. If you do experience difficulties, however, use the information in this chapter to help diagnose and solve the problem. If you cannot resolve the problem, contact Proxim, as described in Appendix F, “How to Reach Technical Support.” How to Obtain Help with Your LAN Installation If you require assistance to install your LAN, Proxim can put you in touch with a RangeLAN2 Reseller in your area.
C) Verify that you are not duplicating IP addresses on your network. D) Verify the Access Point diskette is seated properly inside the RangeLAN2 7500. 2. No response from the RangeLAN2 7500 when configuring locally. There are several possible solutions for this problem: A) Verify that SLIP.BAT is configured for the correct I/O port address and IRQ interrupt of the configuration PC's COM port. B) Verify that there are no IRQ conflicts between the configuration PC's COM port and other cards in the computer.
A) Use remote management to access the RangeLAN2 7500. If this fails, check the Ethernet cabling. B) Use the RL2SETUP program on a wireless client and perform a site survey. If you cannot see the RangeLAN2 7500, you may be using the wrong domain. C) Check the filter settings on the RangeLAN2 7500. Verify that you are not filtering out the kind of traffic you are trying to send. For example, on a Novell network, you do not want to check the IPX protocol box.
POWER LAN 1 LAN 2 RangeLAN2/Access Point proxim There are four LEDs on the RangeLAN2 7100 card that are visible on the back of the RangeLAN2 7500: ❑ The red LED in the bottom right is on steady when the RangeLAN2 7500 is acting as the Master station. There should be only one card on the subnetwork with this light on at any time. ❑ The yellow LED in the upper right is lit when the RangeLAN2 7100 card is synchronized to a Master. ❑ The upper left yellow LED indicates the card is transmitting.
RangeLAN2 7500 Audio Aids As the RangeLAN2 7500 is booting and initializing you will hear several tones. Soon after the machine is turned on, you hear a single beep. Later there are two separate beeps as the machine is initializing. Wait until you hear a multi-tone beep which indicates the RangeLAN2 7500 is now in the forwarding state before attempting to attach to a network. Commonly Asked Technical Support Questions Q.Why can’t I log into the network? A.You may not be in range of the Master.
Q. What do the LAN1 and LAN2 LEDs do? A. LAN1 indicates the RangeLAN2 7500 is transmitting out its wireless side. LAN2 indicates it’s transmitting out the Ethernet side. Q. How do I know if the RangeLAN2 7500 booted up properly? A. Listen for the tones ending with the “Happy” beep. If you don’t hear all the tones, it probably didn’t boot up successfully. Q. What should I do if there are no tones and no LEDs? A. Verify that you’ve put a diskette inside the RangeLAN2 7500 and that it’s labeled “Access Point.
tion to the RangeLAN2 7500. Finally, check the filters to make sure they are not excluding the kind of traffic you need to pass through the RangeLAN2 7500. Q. What does an “X” in a filter box mean? A. It means that kind of traffic will NOT pass through the RangeLAN2 7500. So, if you are using NetWare for example, DO NOT put an “X” in the IPX protocol box. Other If there is additional information that becomes available after the printing of this manual, there will be a README file on the diskette.
A. Setting the RangeLAN2 Security ID As an added security measure, RangeLAN2 allows you to set a Security ID for each RangeLAN2 product installed on a network. All RangeLAN2 products must have matching security IDs in order to communicate. To set the RangeLAN2 Security ID, use the CFG program that came on the driver diskette. Select the correct RangeLAN2 7500 from the list.
B. Upgrading the Software At some point in the future, you may need to upgrade the RangeLAN2 7500 software. To do this, use the CFG tool in the same way in which you would configure the RangeLAN2 7500. In the screen, type the name of the file you would like to be downloaded to the RangeLAN2 7500 in the “Download File” field and also indicate the method you are using to communicate with the RangeLAN2 7500 in the “BOOTP Interface” field.

RangeLAN2 7500 Access Point Addendum Congratulations on your purchase of the RangeLAN2 7500. There are some additional features of this Access Point model that are not described in the User's Guide. Using Across a Router You can use a RangeLAN2 7500 for wireless communication through network routers. In order to use the CFG tool, send pings, or perform any network function through a RangeLAN2 7500 across a router, configure the SNMP parameters for IP Address, Subnet Mask, and Default Gateway.
In the example below, there is a RangeLAN2 7500, a router, and an Ethernet node. The IP Address of the Ethernet node is 192.0.3.7. The router is configured with 2 IP Addresses of 192.0.1.6 and 192.0.3.6. The RangeLAN2 7500 is configured with an IP Address of 192.0.1.5, a Subnet Mask of 255.255.255.0 and a Default Gateway of 192.0.1.6. Your network administrator can help you fill in these fields. Upgrading the Software At some point in the future, you may need to upgrade the RangeLAN2 7500 software.
If you are running the CFG tool with an Ethernet link, enter this command: C:\> WINPKT 0X61 Filters The filter configuration allows you to customize the type of traffic which is forwarded from the Ethernet network to the RangeLAN2 network. When a box is checked, this indicates that traffic that meets the corresponding filter characteristic (e.g., Protocol Type) will be filtered OUT, and will NOT be forwarded.
The ARP FILTER enables IP ARP broadcast filtering. When this filter is enabled, ARP broadcasts will be forwarded from Ethernet to RangeLAN2 only if the destination IP address is on the IP network defined by the IP Network Address and Subnet Mask fields. BROADCAST BANDWIDTH ALLOCATION allows you to specify the maximum percentage of broadcast packets that will be sent from the Ethernet network to the wireless clients. There may be cases when you want to limit broadcast traffic.
Repeating Enabled / Disabled When configuring the RangeLAN2 7500 via the CFG tool, as one of the RangeLAN2 configuration options, you can choose to enable or disable repeating. When repeating is enabled and the RangeLAN2 7500 is configured as a Master, it will repeat any signal coming from one Station and destined for another Station, if the two Stations are both within range of the Master but not within range of one another.
RangeLAN2 7500 Power Cord The RangeLAN2 7500 is provided with power cord that is intended for use in the United States of America only. For continued compliance with harmonized standards, an appropriate approved HAR power cord should be used with the RangeLAN2 7500 in countries other than the United States of America. P/N 7630.
