Wi-Fi Array
Installing the Wi-Fi Array 53
Wiring Considerations
Unless you are using the Xirrus Power over Gigabit Ethernet modules (PoGE)
wit
h an Array that supports PoGE, an AC power outlet must be available to the
Array. If you are using PoGE to distribute power, see “Power over Gigabit
Ethernet (PoGE) (Optional)” on page 10.
Once you have determined the best location for your Wi-Fi Array, you must run
cables to the location for the following services:
Power
One of the following options:
z No power cable is required if using PoGE modules.
z Dedicated AC power if PoGE is not in use. You must use a UL-
approved cord. Order the power cord from the Xirrus product
list—Xirrus supplies only UL-approved power cords.
Network
z Gigabit 1—If using PoGE modules, the Cat 5e or Cat 6 cable from
the Gigabit Ethernet switch to the Array 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.
z Gigabit 2 (optional)
z Fast Ethernet (optional)
z Serial cable— 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 Fast Ethernet, Gigabit 1 or Gigabit 2.
