| 4 - Install the W-118 | 15
As an alternative to PoE, you can insert a compatible power adaptor plug into an AC power outlet
and the other end into the power input port on the W-118.
Note: If you are not using PoE, ensure that you use only an AC power adaptor supported by the
W-118 access point (AP).
Using the W-118 with Power Adapter
To power up the device with power adapter, perform the following steps:
1. Plug the power cable into the DC power receptacle at the rear of the device.
2. Plug the other end of the power cable into an 110V~240V 50/60 Hz AC power source.
3. Wait until the device is ready. Refer to the LED details table.
Connect the W-118 to the Network
To connect W-118 to the network, perform the following steps:
1. Ensure that a DHCP server is available on the network to enable network configuration of the
W-118.
2. Add the DNS entry wifi-security-server on all DNS servers. This entry should point to the IP
address of the server.
3. Ensure that DHCP is running on the subnet to which the device will be connected.
4. Check the status LEDs on the device. If all LEDs glow green, then the device is operational and
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 Devices tab in Wireless Manager and check whether the device is visible under the
Devices tab.
The device is connected and ready to go operational.
Note: If the zero configuration is not successful, the device must be configured manually.
Important: If DHCP is not enabled on a subnet, the device 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 device. See the Access Point
Configuration guide on our website at
