Getting Started Instructions

Step 3: Check the LED status
After the device is powered ON and connected to
the network, a few minutes will pass until the Power/
Ethernet turns solid GREEN. This indicates that the AP is
online and operational.
The LEDs on the AP are: Power, 2.4 GHz, 5 GHz, Third radio,
LAN1, and LAN2.
For all LEDs, green indicates normal operation and orange
indicates a problem.
Troubleshooting
If Power/Ethernet LED is orange, the device is plugged into a non-Gigabit Ethernet switch port.
Using an 802.11 ax Access Point on a 100Mb or 10Mb Ethernet connection may cause performance issues in
the WLAN. Use Gigabit Ethernet uplinks when possible.
1. Check whether the Ethernet cable is plugged into the correct port (PoE+) on the C-250 and the other end
of the cable is plugged into an Ethernet jack or port on a switch that is turned ON.
2. If the C-250 did not receive a valid IP address from the DHCP server, check wether the DHCP server is
ON and available on the VLAN/subnet to which the AP is connected. If the AP still fails to get a valid IP
address, reboot the device once to see if the problem get resolved.
3. If you are using Arista Cloud Services, then open the TCP port 443 (SSL). If you have an on-premises
installation, then open the ports UDP 3851 and port 80. If you are using a Proxy, Web Accelerator or
URL Content Filter in between the AP and the Internet, ensure that the settings allow communication
between the AP and Arista Cloud Services. If your conguration requires you to specify an exact IP
address or IP range for Arista Cloud Services, please contact Technical Support.
Step 2: Connect to the network
If you are using a PoE+ injector, make sure the data connection is plugged into a suitable
switch port with proper network connectivity.
