Rear Panel of C-100
The rear panel of the C-100 provides an PoE Ethernet port that enables you to connect the device to a wired LAN through a
switch or a hub and power the device by using the 802.3af standard.

The Reset Pin Hole resets the C-100 device to factory defaults. To reset the device, press and hold the Reset Pin Hole for 10
sec until all LEDs go off which indicates that the device has rebooted. Pressing the Reset Pin Hole while the device is booting
up will not have any effect. You should perform this operation only when the device is running.
When you reset the device, the following settings are reset:
•Config shell password is reset to config.
•Server discovery value is erased and changed to the default, redirector.online.spectraguard.net (primary) and wifi-
security-server (secondary).
•All the VLAN configurations are lost.
•If static IP is configured on the device, the IP address is erased and DHCP mode is set. The factory default IP address of
the device is 169.254.11.74.
Chapter 4. Install the C-100
This chapter contains the stepwise procedure to install the C-100 device.
Zero-Configuration of C-100 as Access Point
Zero-configuration is supported under the following conditions:
•The device is in AP mode with background scanning on with 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 device looks for the DNS entry wifi-security-server.
•The device is placed on a subnet that is DHCP enabled.
Important: If the device is placed on a network segment that is separated from the server by a firewall, you must
first open port 3851 for User Datagram Protocol (UDP) and Transport Control Protocol (TCP) bidirectional traffic on
that firewall. This port number is assigned to Arista Networks. If multiple devices are set up to connect to multiple
servers, zero-configuration is not possible. In this case, you must manually configure the APs. See the Access Point
Configuration Guide on our website at https://www.arista.com/en/support/product-documentation.
Take a configured C-100, that is, ensure that a static IP is assigned to the device or the settings have been changed for DHCP.
Note down the MAC address and the IP address of the device in a safe place before it is installed in a hard-to-reach location.
The MAC address of the device is printed on a label at the bottom of the product.
Note: You should label the devices using MAC addresses or at least your own convention. For example, use serial
numbers, so that you can easily identify the devices.
The steps to install the device with no configuration (zero-configuration) are as follows:
1. Mount the device. (page 7)
2. Power On the device. (page 8)
3. Connect device to the network. (page 9)
Mount the C-100
The C-100 mounting procedure can be divided into two parts:
1. Affix the bracket to the T -grid: Use the mounting bracket to install the C-100 on the ceiling. Fix the bracket to the T-
grid and rotate the bracket so that it snaps on the T-grid. The bracket is now parallel to an arm of the T-grid. Ensure that
the bracket is properly snapped to the T-grid. Refer to the images given below.

2. Mounting C-100 on the bracket: Place the first mounting post on the rear-side of the device on to the lower notch of the
bracket. Rotate the device such that the center mounting post fits in to the center notch on the bracket. Ensure that all the
mounting posts on the rear-side of the device are snapped in to the respective notches on the bracket. The mounting posts
on the rear-side of the device are now properly fit in the respective notches of the bracket and device is mounted properly.
Mounting Instructions using the Silhouette/Interlude Bracket Mount: The Silhouette/Interlude mounting bracket
is not a part of the standard package and must be procured separately. The mounting instructions for the Silhouette/
Interlude Bracket Mount are very similar to the Standard Package Content's mounting instructions.
Power On the C-100
The C-100 device can be powered on by plugging one end of the Ethernet cable into the PoE (802.3af) switch or injector and
the other end into the Ethernet/PoE port on the C-100. Ensure the PoE source you are using is turned ON.
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 C-100.
C-100 | 4 - Install the C-100 | 9
Note: If you are not using PoE, ensure that you use only an AC power adaptor supported by the C-100 access
point (AP).
Connect the C-100 to the Network
To connect C-100 to the network, perform the following steps:
1. Ensure that a DHCP server is available on the network to enable network configuration of the C-100.
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. See
the Access Point Configuration Guide on our website at https://www.arista.com/en/support/product-
documentation.
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.
Connect the C-100 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.
Using the C-100 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.
