Installing the Wireless Array 61
Wiring Considerations
Before using the Xirrus-supplied Power over Gigabit Ethernet modul
es (PoGE) to
distribute power, see “Power over Gigabit Ethernet (PoGE)” on page 13.
Once you have determined the best location for your Wireless Array, you must
run cables to the location for the following services:
Power
 No separate power cable to the Array is required when using
PoGE modules. The PoGE module requires a dedicated AC
power outlet (100 - 240 VAC).
Network
 Gigabit POE1 — the total of all Cat 5e or Cat 6 cable segments
from the Gigabit Ethernet switch to an Array Ethernet port must
be less than 100m long. The Array must be connected to PoGE
networks without routing cabling to the outside plant, to ensure
that cabling is not exposed to lightning strikes or possible high
voltage crossover.
 Gigabit POE2—For Arrays with a second POE port, the same
restrictions listed above apply.
 Serial cable (optional) — cable lengths up to 25’ per the RS-232
specification.
Important Notes About Network Connections
Read the following notes before making any network connections.

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 Array can be managed from any of the
available network connections, either Gigabit 1 or Gigabit 2.

For models with no console port, such as the XR-500, XR-1000, and some
XR-2000 models, the Xirrus Xircon utility may be used locally to set up an
IP address if necessary.
