Quick Installation Guide
For XA4 Models
XA4 Series High Density Convention Center Access Points (CCAPs) are plenum-
rated indoor APs using external antennas. With four 802.11ac Wave 2 radios, a
powerful integrated controller, application-level intelligence, automated
provisioning, and optional cloud management, the APs deliver robust wireless
connectivity in areas of medium to high user density. The XA4-240 has four 4x4
Wave 2 802.11ac radios: radio IAP1 is a dual-band 2.4GHz/5GHz radio, and IAP2
through IAP4 are single-band 5GHz radios.
This Guide describes how to install and start the AP. For detailed configuration information, see the User’s Guide
or online help for the Cambium Xirrus XMS management system for APs (XMS), or the
Wireless Access Point User's
Guide
.
You Need the Following Items
Accessory Kit (included in each AP carton) includes Mounting plate.
Cambium Xirrus-recommended antennas (and cables if needed) for up to four radios. If you are not using
recommended antennas with four connectors, network designers should specify how many antennas to install
for each radio—see the table in
to see which connectors to use. Cables (if needed)
are low-loss coaxial cables terminated with RP-SMA connectors. See
for recommended
antennas.
Power and Ethernet connection(s) to your wired network using Cat 5e/6 cables. The AP has 2 Ethernet ports:
GIG1/POE
—
This 2.5 Gigabit port powers the AP via Power over Ethernet (PoE) using a Cat 5e or Cat 6
cable that also carries data traffic. See below for Power details. Note that the port’s rate is always set by
auto-negotiation with the switch.
(Optional)
GIG2
—
Connection to this second, data-only one-gigabit port provides additional bandwidth.
Use Cat 5E or Cat 6 cable.
AP must be connected to PoE networks without routing cabling to the outside plant. This ensures that cabling is
not exposed to lightning strikes or possible crossover from high voltage lines. AP, PoE Injectors, or Switches must
be installed and used indoors. The total Cat 5e or Cat 6 cable length from the switch to the AP must be no more
than 100 m, including all cable segments.
Power— See the matrix below to select a compatible Cambium Xirrus-supplied injector for your AP. If using
an injector, you must provide a data connection from the switch to the injector as well as another cable from
the injector's OUT port to the AP’s GIGABIT1/PoE port. PoE injectors require an AC outlet.
The models listed above (XP1-MSI-75, XP8-MSI-70M) typically require a dongle to be connected in-line
between the AP and the power injector, as instructed in
Power Dongle for XD4-240/XA4-240
. This document
and the dongle are supplied with your AP if they are needed.
