Reduced capability indicates that the AP is getting lower than the required maximum power from the
PoE switch, i.e., 802.3af instead of 802.3at.
LAN1 LED: ON when the corresponding interface is up.
LAN2 LED: ON when the corresponding interface is up and either wired guest or link aggregation is
configured.
Radio LEDs: ON when the corresponding radio is operational.
Bottom Panel of O-105E
The bottom panel of the O-105E has LAN or 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.

Chapter 4. Install the Access Point
This chapter contains the stepwise procedure to install the access point (AP).
Zero-Configuration of O-105E 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, the AP 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 to Arista 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 the AP 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-105E (on page 10) or Pole Mount the O-105E (on page 7)
2. Power On the O-105E (on page 13)
3. Connect the O-105E to the Network (on page 14)
Pole Mount the O-105E
Use the pole-mount bracket and pole strap to install the O-105E device on a pole. Standard
accessories include two metal clamps.:
Use the mounting base to install the O-105E device on the wall. To mount the device:

O-105E | 4 - Install the Access Point | 8
1. Attach the device to the mounting base.
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-105E
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.

Connect External Antennas to O-105E
Connect the external antennas to their respective ports using "N Type" connectors.

Power On the O-105E
An O-105E 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 PoE port on O-105E of
nominal input voltage 48V DC.

O-105E | 4 - Install the Access Point | 14
Note: If you are not using PoE, ensure that you use only an AC power adaptor supported by the
O-105E access point (AP).
Connect the O-105E 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 the AP. 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-105E 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.

Chapter 5. Access Point Troubleshooting
The table below lists some of the troubleshooting guidelines for the access point (AP).
Problem Solution
The AP did not receive a valid IP address via the
DHCP. Ensure that 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, you can reboot it to see if the problem is
resolved.
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
has Access Control Lists (ACLs) enabled
between the AP 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 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 you are using a Proxy, Web Accelerator,
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-
[email protected].

Chapter 6. Appendix A: AP-Server Mutual
Authentication
The AP-server communication begins with a mutual authentication step in which the AP and server
authenticate each other using a shared secret. The AP-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.
The AP and server are shipped with the same default value of the shared secret. Both the server and
the AP have CLI commands to change the shared secret.
Note: After the shared secret (communication key) is changed on the server, all APs connected
to the server will automatically be set up to use the new communication key. You must manually
configure the new communication key on an AP 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.
