❑RangeLAN2 754x Extension Point extends the coverage area of an existing
RangeLAN2 network.
❑RangeLAN2 791x Serial Adapter is a wireless serial device which acts as a
replacement for an RS-232 cable.
❑RangeLAN2 792x Ethernet Adapter converts any Ethernet-ready device into
a wireless node on a RangeLAN2 network.
❑There are three choices of the RangeLAN2 Ethernet Access Point -- the 7510,
the 7520, and the 7521. The 7520 and 7521 are identical units, except that the
7521 has 500 mW of output power and the 7520 has 100 mW of output power.
Since the 7520 and the 7521 have an identical feature set, the two models are
collectivelyreferred to as 752xwithin this manual. Thefeature differences
between the 7510 and the 752x are described in the following table:

2. Quick Installation
You may follow the quick installation steps if the following conditions are true:
❑There will only be one Access Point on this network
❑You will use all the software default values
❑You do not need to configure an IP address for the Access Point and do not
intend to manage it via telnet or a Web browser
❑You will not be setting security IDs on your network
Iftheabove conditionsarenot true,moredetailed configurationinformationis described
in Chapter 5.
Ifyourinstallationmeetstheprecedingcriteria,proceedwiththefollowinginstructions:
1. Firmly screw in clockwise the antenna onto the antenna connector on the back
panel of the Access Point.
Note
Governmentregulatoryagenciesmandatethatthe antennanotbealterable.
Therefore, RangeLAN2 Access Point uses a custom antenna connector. Do
not attempt to use a different antenna or you may damage the connector and
the Access Point unit.

2. Attach an Ethernet cable to the Ethernet port on the back of the RangeLAN2
AccessPoint.
3. Plug the power cable into the back of the RangeLAN2 Access Point and into
an AC power outlet. Since there is no On/Off switch on the Access Point box,
the unit will turn on as soon as power is applied.

3. Installation
Ethernet Installation
The RangeLAN2 Access Point is attached to the wired LAN backbone via an Ethernet
cable. Two types of Ethernet connection are supported: 10BaseT and 10Base2.
10BaseT Cabling
The RangeLAN2 Access Point 10BaseT cable is typically connected between the
device and a 10BaseT hub or wiring rack. It will use the same cable that would other-
wise be plugged into a 10BaseT workstation on the Ethernet LAN. If you are using a
functional cable, the LED nearest the connector will light. Standard 10BaseT specifica-
tions apply to the 10BaseT interface of the RangeLAN2 Access Point. No segment can
exceed100 meters.
10Base2 Cabling
When using 10Base2 cabling with the RangeLAN2 Access Point, the cable must be
properly terminated on each end. Standard 10Base2 specifications apply to the 10Base2
interface of the RangeLAN2 Access Point. Each coax cable segment can support up to
30 devices and the cable itself cannot exceed 185 meters.
Antenna Options
The RangeLAN2 Access Point is shipped with a standard directly-connected antenna.
To install the antenna, screw it clockwise onto the antenna connector. Proxim sells
severalantenna alternatives includinghigher gain anddirectional antennas. Each of
theseantennasships withinstallationand mountinginstructions. Forinformation on
additionalantennaoptions,pleasecontactyourProximSalesRepresentative.
Mounting Options
The RangeLAN2 Access Point may be placed on a desktop or mounted to a wall. An
optional mounting hardware bracket is available for purchase in order to attach the unit
to a cubicle or a wall. Figure 3 and Figure 4, below, display these different mounting
options.
