Xirrus Wi-Fi Array XN16 User manual

Wi-Fi Array™
812-0004-001A
Quick Installation Guide
This Guide covers the steps required to install the Xirrus XN16 or XN8 Wi-Fi Array on a T-bar
ceiling and execute the initial power up of the Array. If installing the Array with a wall bracket
(XS-BKT-WALL-3900-3700), indoor enclosure (XE-2020), or outdoor enclosure (XE-4000,OUT),
refer to the accompanying Quick Installation Guide shipped with those products.
Product specifications start on page 9. For additional information and advanced installation
instructions, see the Wi-Fi Array User’s Guide (part number 800-0006-001).
You Need the Following Items:
wWi-Fi Array Accessory Kit (included in the Wi-Fi Array shipping carton).
wOptional serial console cable (included). Cable lengths up to 25’ are supported, per the
RS-232 specification
wDedicated AC power source adjacent to each unit, or remote AC outlet(s) if using the
optional Xirrus Power over Gigabit Ethernet (PoGE) single port or eight port modules.
If using PoGE, the Array must be connected to PoGE networks without routing cabling to the
outside plant—this ensures that cabling is not exposed to lightning strikes or possible cross
over from high voltage lines.
wCopper Ethernet connection(s) to your wired network.
wWorkstation with a Web browser to configure the Wi-Fi Array.
wFlat screwdriver and 7/16” nut driver for attaching the T-bar clips to the ceiling grid.
wKnife for cutting an access hole in the ceiling tile.
Choose a Suitable Location
wThe best location is ceiling-mounted within an open plan environment.
wChoose a location that is central to your users. Refer to the Wi-Fi Array User’s Guide for
placement details—part number 800-0006-001.
wKeep the unit away from electrical devices or appliances that generate RF noise—at least
3 to 6 feet (1 to 2 meters).
wMaintain a distance of 50 feet between additional Wi-Fi Arrays.

Attach the T-Bar Clips to the Template
Refer to Figure 1.
wPre-load the 4 T-bar clips through the holes in the mounting template and twist the clips
until they are correctly aligned with the markings on the template.

Secure the T-Bar Clips to the Ceiling Support Grid
Refer to Figure 2.
wThe mounting template should be oriented in such a way that the Array’s abg2 omni-
directional monitoring IAP (radio) is pointing in the direction of the least required
wireless signal coverage—for example, a nearby exterior wall or entrance.
wUse the mounting template to find the correct location for all four T-bar clips (step a),
then twist the T-bar clips onto the metal ceiling support grid and tighten the screw posts
to 10-12 lbf.ft (1.38-1.66 kgf.m)—steps b and c. Do not overtighten the screw posts.
wCut an access hole for the cables in the ceiling tile (step d).
wDisengage the template from the screw posts (4 places) and remove the template from
the ceiling.

Install the Mounting Plate
Refer to Figure 3.
wAlign the Array’s mounting plate and secure it to the four T-bar clips using the nuts
provided (steps e and f). Tighten the nuts to 10-12 lbf.ft (1.38-1.66 kgf.m), but do not
overtighten.

Connect the Cables
Refer to Figure 4.
wFeed the power and Ethernet cable(s) through the access hole in the ceiling tile and the
mounting plate, then connect the cables to the Array (steps g and h). The Ethernet
cable(s) should be connected as follows:
zGigabit 1 (mandatory)—used for the primary data and management connection
to the Array.
zGigabit 2 (optional)—used as a redundant connection to Gigabit 1.
zFast Ethernet (optional)—used for a management-only connection to the Array.
wTurn ON the power switch.
wVerify that the Ethernet link LED lights and the LED boot sequence begins—the IAP
LEDs on the front of the Array will illuminate in rotation.

Attach the Wi-Fi Array to the Mounting Plate
Refer to Figure 5.
wAlign the keyed slot in the center of the Array with the key post on the mounting plate.

wTurn the Wi-Fi Array to the right to lock the unit into place—similar to the assembly of a
smoke detector.

Log In to the Wi-Fi Array
Refer to Figure 6.
wEstablish a network connection to the Array. Be aware of the following:
zBy default, the Array's Ethernet interfaces use DHCP to obtain an IP address.
zOpen a Web browser. In the URL field, enter the IP address assigned by your
DHCP server.
zIf the assigned IP address is unknown, it can be read via the Array's serial port
from the Command Line Interface (refer to the Wi-Fi Array User’s Guide for more
information—part number 800-0006-001).
To connect directly to the Array console port, your computer must be equipped
with a male 9-pin serial port and terminal emulation software (for example,
HyperTerminal). Use the following settings when establishing a serial connection:
zIf a DHCP server is not being used, you may connect using the Array’s default IP
addresses (10.0.2.1 for Gigabit 1 and Gigabit 2, and 10.0.1.1 for Fast Ethernet).
zYour workstation must be configured to be on the same subnet as the Array.
wAt the Security window, click on the Continue or Yes button.
wAt the login prompt, enter the default user name and password (the default is admin for
both).

wEnter your basic configuration data, then click on the Save button to save your settings.
wClick on the Execute button to configure and enable all IAPs (radios) automatically.
wWith a basic configuration established the Wi-Fi Array is now functional. Refer to the
User’s Guide (part number 800-0006-001) for additional configuration information.
