Installing the XS-3900
This section provides instructions for installing the XS-3900 unit.
Choosing a Location
Based on coverage, capacity and deployment examples discussed earlier in this
chapter, choose a location for your XS-3900 that will provide the best results for
your needs. The XS-3900 was designed to be mounted on a ceiling where the unit
is unobtrusive and wireless transmissions can travel unimpeded throughout open
plan areas. Choose a location that is central to your users.
Wiring Considerations
Unless you are using the Xirrus Remote DC Power System (XP-3100) with the DC
version of the XS-3900, an AC power outlet must be available to the XS-3900 (an
AC power cord is provided with each unit). If you are using the XP-3100 to
distribute DC power to multiple XS-3900 units, go to “Remote DC Power System
(Optional)” on page 8.
Once you have determined the best location for your XS-3900, you must run
cables to the location for the following services:
Power
z Dedicated AC power
z DC power (if using the XP-3100)
Network
z Gigabit 1
z Gigabit 2 (optional)
z Fast Ethernet (optional)
z Serial cable (see note)
#
When the unit’s IP address is unknown or a network connection has not been
established, the serial cable is used for connecting directly with the Command
Line Interface (CLI) via HyperTerminal. When a network connection is
established, the XS-3900 can be managed from any of the available network
connections, either Fast Ethernet, Gigabit 1 or Gigabit 2.
