Chapter 4
Installing the Access Point
This chapter contains the stepwise procedure to install the access point (AP).
Zero-Configuration of the Access Point The AP supports zero-configuration under the following conditions: · The device must be in AP mode with background scanning on and without a configured SSID. · Set up a DNS entry fo wifi-security-server on all the DNS servers. This entry should point to the server IP
address. By default, the AP looks for the DNS entry wifi-security-server. · Place the AP on a DHCP-enabled subnet.. Refer to these articles to understand how the APs communicate with the server, and the ports you need to open to enable the communication: · Wi-Fi Access Points-Server Communication · TCP Ports and UDP Ports Used by Access Points
Important: If placing the device on a network segment separated from the server by a firewall, you must first open port 3851, the port assigned to Arista Networks, for User Datagram Protocol (UDP) and Transport Control Protocol (TCP) bidirectional traffic on the firewall. Zero-configuration does not support setting up multiple devices to connect to multiple servers. In this case, you must manually configure the APs. See the Access Point Configuration Guide at Arista Product Documentation. Assign a static IP address to the AP or change the settings to DHCP. Make a note of the AP MAC address and the IP address in a safe place before installing it in a hard-to-reach location. Locate the AP MAC address on a label at the bottom of the product. Use the following steps to install the AP with zero-configuration: 1. Pole Mounting the AP 2. Connecting the Access Point to the Network 3. Powering on the Access Point
4.1 Pole Mounting the AP
Use the mounting bracket and metal clamps to install the AP on a pole. Standard accessories include the mounting bracket and two metal clamps. To mount the AP on a pole: 1. Insert the two metal clamps into the bracket. You can insert the clams either in the horizontal or vertical
slots depending on the position the pole-mount bracket for use on a vertical or horizontal pole.

Powering on the Access Point Warning - The O-435E AP requires a UL-listed PoE power source suitable for use at 45ºC. The power output should meet LPS requirements or PS2, with a rating of 48V DC (1A minimum). The current supplied by PoE+ + should be 850mA. If not using PoE++, ensure that you use only an AC power adapter supported by the AP. The power adapter should be suitable for use at 45ºC. Use this product with a Listed Direct Plug-In Power Unit marked as Class 2, Listed Power Adapter, or DC power source marked L.P.S. (or Limited Power Source) and rated from 12 V DC, 4A minimum. The maximum altitude of operation for the power adapter is 5000m. To power up the device with power adapter, perform the following steps: 1. Plug the power cable into the DC power receptacle on the back of the AP. 2. Plug the other end of the power cable into an 110V~240V 50/60 Hz AC power source. 3. The LED lights turn on when ready. Refer to the LED status table.

Chapter 6
Connecting the Access Point to the Network
To connect the AP to the network, perform the following steps: 1. Be sure to install the AP on a network with a DHCP-enabled server. 2. Add the DNS entry wifi-security-server on all DNS servers. This entry must point to the server IP
address. By default, the AP looks for the DNS entry, wifi-security-server. 3. Verify the AP LED status as ON. 4. Log on to the server using SSH and run the get sensor listcommand.
The command returns a list of all Arista devices recognized by the server. Single Sign-On users can go to the Monitor tab in CloudVision WiFi and check if the device appears on the tab.
Note: If zero configuration fails, the AP must be configured manually. Important: If the subnet does not have DHCP enabled, the AP cannot connect to that subnet with zero-configuration. If no DNS entry exists on the DNS servers, or if you do not have a DHCP server running on the subnet, you must manually configure the AP. For details on configuring an AP manually, refer to the Access Point Configuration Guide on Arista Product Documentation.
6.1 Connecting the Access Point using PoE
If using a PoE injector, plug the data connection into a suitable switch port with proper network connectivity. Figure 6-1: LAN Port
The figure shows the LAN cable inserted to the LAN1 Port. Label l points to the relative position of the grounding screw on the AP. For PoE port details, see the Bottom Panel section.

Chapter 7

Access Point Troubleshooting

The table below lists some of the troubleshooting guidelines for the access point (AP).

Problem The AP did not receive a valid IP address via the DHCP.
Unable to connect to the server.

Solution
Be sure you have an active DHCP server on the VLAN or subnet with the connected AP. If the AP fails to get a valid IP address, reboot it to see if that resolves the problem.
· Be sure you have an active server reachable from the network with the connected AP.. If a firewall or a router has Access Control Lists (ACLs) enabled between the AP and the server, be sure to allow traffic on UDP port 3851.
· Use the IP-based server discovery method and be sure you have correctly entered the DNS name, wifi-security-server, on the DNS server.
· Be sure that the DNS server has correctly configured IP addresses or the DHCP server provides the IP addresses.
· The AP might fail to authenticate with the server. In this case, an 'Authentication failed ' event logs to the server. Refer to the event for recommended action.

The AP has encountered a problem.

· If using Arista Cloud Services, then open the TCP port 443 (SSL). If you have an on-premises installation, then open UDP port 3851 and port 80.
· If using a Proxy, Web Accelerator, or URL Content Filter between the AP and the Internet, be sure the settings allow communication between the AP and Arista Cloud Services.
· If your configuration requires you to specify an exact IP address or IP range for Arista Cloud Services, please contact [email protected].

Chapter 8 Appendix A: AP-Server Mutual Authentication
The AP-server communication begins with a mutual authentication step where the AP and server authenticate each other using a shared secret. If this authentication succeeds, the AP-server communication takes place. After the authentication succeeds, the server generates a session key and encrypts all communication between the AP and server using the session key. The AP and server ship with the same default value of the shared secret. Use CLI commands on the server and the AP to change the shared secret.
Note: After changing the shared secret on the server, all APs connected to the server automatically use the new communication key. You must manually configure the new communication key on an AP if not connected to the server when the key changes on the server. Note: Arista Networks does not recommend installing older versions of APs on newer versions of servers. For more information on the AP-server communication process, see the Wi-Fi Access Point Server Communication Workflow article.
