Install the C-130E
This chapter contains the step wise procedure to install the C-130E device.
Zero-Configuration of C-130E as Access Point
Zero-configuration is supported under the following conditions:
• The device is inAP 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 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 toArista 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 configuredAP; that is, ensure that a static IP is assigned to the AP or the settings have been changed for
DHCP. Note down 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 device are as follows:
•Mount the C-130E on page 11
•Power the Access Point On on page 14
•Connect Access Point to the Network on page 15
Mount the C-130E
The steps to mount the C-130E involve:
•Mounting Instructions using the Standard Package Contents on page 11
•Mounting Instructions using the Silhouette or Interlude Bracket Mount on page 14
•Mounting Instructions using the Wall Mount Bracket on page 13
Important: To prevent disconnection or tampering by unauthorized personnel, it is extremely important
to install the device such that it is difficult to unplug the device from the network or from the power outlet.
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.
Mounting Instructions using the Standard Package Contents
The mounting procedure can be divided into two parts:
11

1. Affixing the bracket to the T -grid: Use the mounting bracket to install the C-130E 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-130E 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.
C-130E12

Mounting Instructions using theWall Mount Bracket
The Wall mounting bracket is not a part of the standard package and must be procured separately. Attach the
wall-mounting bracket with the help of screws on to the wall. Pull the side latch to unlock the wall mount bracket.
Affix the device on the wall mount bracket by placing the device stubs in the bracket's placeholder. Lock the
side latch and affix the device firmly with the screw.
13

Mounting Instructions using the Silhouette or 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. Refer to the instructions mentioned in Mounting Instructions using the Standard
Package Contents on page 11 .
Power the Access Point On
The C-130E device can be powered on by plugging one end of the Ethernet cable into the PoE+ (802.3at) switch
or injector and the other end into the Ethernet/PoE+ port on the C-130E. Ensure the PoE+ source you are using
is turned ON.
Note: You can also use regular PoE (802.3af). However, there are certain drawbacks to it:
• The USB is disabled.
• The other ethernet port is disabled.
• The 2.4 GHz radio is downgraded to 1x1 TX/RX capability and Tx power of 15 dBm or lower, (or as set in
the device template)
• The 5 GHz radio is downgraded to 2x2 18 dBm or lower, (or as set in the device template)
As an alternative to PoE+, you can insert a power adaptor plug into an AC power outlet and the other end into
the power input port on the C-130E.
C-130E14

Using C-130E 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 HzAC power source.
Wait for few minutes for the device to power on. Further you can refer the LED details table to verify the
functioning of the device.
Connect Access Point to the Network
The device can be connected to the network by connecting through a LAN cable or a POE+ injector. If you are
using a PoE+ injector, make sure the data connection is plugged into a suitable switch port with proper network
connectivity.
To connect C-130E to the network, you should meet the following prerequisites:
•Ensure that a DHCP server is already available on the network to enable network configuration of the C-130E.
•DNS should be able to resolve the server discovery primary: redirector.online.spectraguard.net, secondary:
wifi-security-server).
•AP with valid IP address from DHCP server or a valid static IP address1 to communicate with Wireless Manager.
• Check the LEDs Status on the device to ensure that it is operational and connected to the server.
If the conditions above are true, the device should be connected and ready to go 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 anAP
manually, see the Access Point Configuration guide on our website at
https://www.arista.com/en/support/product-documentation .

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, 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-wifi@arista.com.

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.All communication between the AP and server
from this point on 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, all APs connected to the
server will automatically be set up to use the new communication key. APs that are not connected to the
server at this time must be manually set up with the same communication key to enable communication
with this server.
Note: Although the server is backward compatible—that is, older version APs can connect to a newer
version server—this is not recommended.
