Bottom Panel of O-105
The bottom panel of the O-105 has LAN/PoE connectors that enable you to connect the device to a wired LAN
through a switch or a hub. The ports provide power for the device by using the 802.3at standard.

Install the Access Point
This chapter contains the stepwise procedure to install the access point (AP).
Zero-Configuration of O-105 as Access Point
Zero-configuration is supported under the following conditions:
• The device is in AP mode with background scanning on and no SSID configured.
• A DNS entry wifi-security-server is set up on all the DNS servers. This entry should point to the IP address
of the server. By default, theAP looks for the DNS entry wifi-security-server.
• The AP is on a subnet that is DHCP enabled.
Important: If the AP is on a network segment that is separated from the server by a firewall, you must
first open port 3851 for bidirectional User Datagram Protocol (UDP) and Transport Control Protocol
(TCP) traffic on that firewall. This port number is assigned toArista Networks. Zero-configuration cannot
work if multiple APs are set up to connect to multiple servers. In this case, the APs must be configured
manually. For details on how to configure an AP manually, see the Access Point Configuration Guide on
our website at https://www.arista.com/en/support/product-documentation .
Take a configured AP; that is, ensure that a static IP is assigned to the AP or the settings have been changed for
DHCP. Note the MAC address and the IP address of theAP in a safe place before it is installed in a hard-to-reach
location. The MAC address of the AP is printed on a label at the bottom of the product.
The steps to install the AP with no configuration (zero-configuration) are as follows:
1. Wall Mount the O-105 on page 12 or Pole Mount the O-105 on page 10
2. Power On the O-105 on page 15
3. Connect the O-105 to the Network on page 15
Pole Mount the O-105
Use the pole-mount bracket and pole strap to install the O-105 device on a pole. Standard accessories include
two metal clamps.:
Use the mounting base to install the O-105 device on the wall. To mount the device:
1. Attach the device to the mounting base.
Quick Start Guide: Access Point10

2. Attach the pole-mount bracket to the mounting base.You can position the pole-mount bracket for use on a
vertical or horizontal pole. Insert the pole strap in to the pole-mount bracket.
3. Mount the device securely to the pole by using the pole strap and a Philips #2 screwdriver.

Wall Mount the O-105
Mounting the access point (AP) on the wall consists of the following steps:
1. Affix the expansion bolts on the wall such that the holes on the mounting base can be perfectly placed over
them.

Quick Start Guide: Access Point14

Power On the O-105
An O-105 device can be powered on by plugging one end of the Ethernet cable into the 802.3at Power Over
Ethernet+ (PoE+) switch or injector and the other end into the Ethernet/PoE part on O-105 of nominal input
voltage 48V DC.
Note: If you are not using PoE, ensure that you use only an AC power adaptor supported by the O-105
access point (AP).
Connect the O-105 to the Network
To connect the access point (AP) to the network, perform the following steps:
1. Ensure that a DHCP server is available on the network to enable network configuration of the AP.
2. Add the DNS entry wifi-security-server on all DNS servers. This entry must point to the IP address of the
server.
3. Ensure that DHCP is running on the subnet to which the AP is connected.
4. Check the LEDs on the AP to ensure that it is connected to the server.
5. Log on to the server using ssh and run the get sensor list command.
You will see a list of all Arista devices that are recognized by the server. Single Sign-On users can go to the
Monitor tab in CloudVision WiFi and check whether the device is visible under the Monitor tab.
The AP is connected and operational.
Note: If zero configuration fails, the AP must be configured manually.
Important: If DHCP is not enabled on a subnet, the AP cannot connect to that subnet with
zero-configuration. If the DNS entry is not present on the DNS servers, or if you do not have the DHCP
server running on the subnet, you must manually configure theAP. For details on configuring an AP
manually, see the Access Point Configuration guide on our website at
https://www.arista.com/en/support/product-documentation .
Connect the O-105 using PoE
If you are using a PoE injector, make sure the data connection is plugged into a suitable switch port with proper
network connectivity.

Access PointTroubleshooting
The table below lists some of the troubleshooting guidelines for the access point (AP).
SolutionProblem
Ensure that the DHCP server is on and available on theVLAN/subnet
to which the AP is connected. If the AP still fails to get a valid IP
address, you can reboot it to see if the problem is resolved.
The AP did not receive a valid IP address via the DHCP.
Unable to connect to the server. •Ensure that the server is running and is reachable from the network
to which the AP is connected. If a firewall or a router hasAccess
Control Lists (ACLs) enabled between theAP and the server, ensure
that traffic on UDP port 3851 is allowed.
•Use the IP-based server discovery method and ensure that you have
correctly entered the DNS name, wifi-security-server , on the DNS
server.
• Ensure that the DNS server IP addresses are either correctly
configured, or are provided by the DHCP server.
• The AP might fail to authenticate with the server. In this case, an
'Authentication failed ' event is raised on the server. Refer to the
event for recommended action.
The AP has encountered a problem. •If you are usingArista 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 you are using a Proxy, WebAccelerator, or URL Content Filter
between the AP and the Internet, ensure that 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
support-wifi@arista.com.
Quick Start Guide: Access Point16

Appendix A: AP-Server Mutual
Authentication
TheAP-server communication begins with a mutual authentication step in which theAP and server authenticate
each other using a shared secret. TheAP-server communication takes place only if this authentication succeeds.
After the authentication succeeds, a session key is generated. From this point on, all communication between
the AP and server is encrypted using the session key.
TheAP and server are shipped with the same default value of the shared secret. Both the server and theAP have
CLI commands to change the shared secret.
Note: After the shared secret (communication key) is changed on the server, allAPs connected to the
server will automatically be set up to use the new communication key.You must manually configure the
new communication key on anAP if it is not connected to the server when the key is changed on the
server.
Note: Although the server is backward compatible—that is, older version APs can connect to a newer
version server—this is not recommended.
