Wireless Access Point
52 Installing the Wireless AP
When you add IAPs to an AP or replace 802.11n IAPs with 802.11ac
modules, the Access Point determines its model number based on the
count and types of radios. For example, if you add four 1300 Mbps (3X3
MIMO) IAPs to an XR-4420, the AP will display its model number as XR-
4836 because it now has eight 3x3 IAPs including 802.11ac radios.
Failover Planning
This section discusses failover protection at the unit and port levels. To ensure
that service is continued in the event of a port failure, you can utilize two Gigabit
Ethernet ports simultaneously as a bonded pair (on APs with two or more Gigabit
ports).
Figure 24. Port Failover Protection
Xirrus highly recommends that the upgraded Array have a radio count that
matches one of our standard Arrays (e.g., XR-4000 with 4 or 8 radios, XR-
2000 with 2 or 4). The Array may have more of one type of radio than
another. For example, an upgraded XR-4830 may have six 802.11n radios
and two 802.11ac radios, or vice versa.
