As the access point attempts to connect to the controller, the LEDs cycle through a green-red-amber sequence, which can
take up to 5 minutes.
Note
•
If this connection takes longer than five minutes, the access point cannot find the
master
Cisco Wireless
LAN Controller. Check the connection, and ensure that both are on the same subnet.
•
To prevent Ethernet port bottlenecks due to wireless traffic speeds exceeding 10/100 Ethernet port transmit
speeds, the Cisco IW3702 access point requires a Gigabit Ethernet link.
•
If the access point shuts down, check the power source.
After a successful connection, the access point compares operating system code versions with the Cisco Wireless LAN
Controller. If versions differ, it downloads the newest version. The Status LED blinks dark blue during this process. On
a successful download, the access point reboots.
Step 3
(Optional) Configure the access point.
Use the controller CLI, controller GUI, or Cisco Prime Infrastructure to customize access-point-specific IEEE 802.11ac
network settings.
On successful access point priming, the Status LED is green indicating normal operation.
Step 4
Disconnect the access point and mount it in location.
•
If the access point LEDs do not indicate normal operation,
turn it off and repeat the access point priming procedure
(see
Performing a Pre-Installation Configuration, on
page 55
).
•
When installing a Layer 3 access point on a different
subnet than the Cisco Wireless LAN Controller, ensure
that:
◦
a DHCP server is reachable from the subnet on
which you are installing the access point and that
subnet has a return route to the Cisco Wireless LAN
Controller.
◦
the return route to the Cisco Wireless LAN
Controller has destination UDP ports 5246 and 5247
open for CAPWAP communications.
◦
the return route to the primary, secondary, and
tertiary Cisco Wireless LAN Controllers allows IP
packet fragments.
◦
if using address translation, the access point and
the Cisco Wireless LAN Controller have a static
1-to-1 NAT to an outside address. (Port address
translation is not supported.)
