You can connect the device to the network using PoE or a power adapter. Connect C-75 to the Network To connect C-75 to the network, perform the following steps. 1. Ensure that a DHCP server is already available on the network to enable network configuration of the C75. C-75 Installation Guide 14 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. 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 you do not have the DHCP server running on the subnet, you must manually configure the device. Refer to Manually Configuring C-75 for further details. Using C-75 with PoE To power on and connect C-75 to the network using PoE, do the following: 1. Connect one end of the network interface cable to the Ethernet port at the rear of the C-75. 2. Connect the other end of the network interface cable to the Ethernet jack that provides PoE power. Note: The equipment must be connected to PoE networks, for indoor use only. In other words, the equipment is to be connected only to PoE networks without routing to the outside plant. Figure 3-3. Power Up and Connect C-75 using PoE Using C-75 with power adapter To power up the device, 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. Wait until the device is ready. Refer to the respective LED details table based on the configured device mode. C-75 Installation Guide 15 Figure 3-4. Power Up C-75 To connect C-75 to the network, perform the following steps: 1.

Connect the other end of the network interface cable to an Ethernet jack on the desired subnet. Wait until the device is ready (approx. 10 mins). Figure 3-5. Connect C-75 to network 4. Check the status LEDs on the device. If all LEDs glow green, then the device is operational and connected to the server. C-75 Installation Guide 16 5. Log on to the server through SSH and run the get sensor list command. You would see a list of all AirTight devices that are recognized by the server. AirTight Cloud Services users can go to the Devices tab and check whether the device is visible under the Devices tab. The device is configured and ready to go operational. Note: If the zero configuration is not successful, the device must be configured manually. Refer to Manually Configuring C-75 for details. C-75 Installation Guide 17 4. Manually Configuring C-75 Important: If the installation in the previous chapter was successful, stop! You do not need to configure the device manually. Introduction Manual configuration of C-75 is typically required in the following cases: Devices cannot connect to the server through zero-configuration. The DNS entry for the server has been changed to an entry other than wifi-security-server or a DNS server is not present in the network. This is applicable for multi-server installations. Device is placed on a subnet that is not DHCP enabled. Configuring AP through Config Shell The Config Shell supports a pre-defined set of commands used to configure the C-75 device. Log in to the device console using the SSH shell. The steps to configure the device manually through the SSH shell are as follows: 1. Log in and change the default password 2. Set Server Discovery 3. Configure Network Settings Log in and Change the Default Password Log in to the Config Shell using the user name config and password config. Change the default password using the passwd command. You can change the device password using device templates. Refer to Device Template section under the Administration Tab chapter, in the Users’ Guide for more details. Recommended: Although not mandatory, as a best practice we recommend that you change the default password. Set Server Discovery The next step is to set the server discovery information. The following are the types of server discovery: Server IP based discovery (preferred) Service Location Protocol (SLP) based discovery (if wifi-security-server service has been configured) Use the set server discovery command to point the AP device to the correct server. C-75 Installation Guide 18 Figure 4-1 The set server discovery Command Note: If IP address/ host name based discovery is being used and more than one server is present on the network, then you must enter the IP address of the appropriate server. Configure Network Settings Configure a static IP address in absence of a DHCP server 1. Connect a crossover cable from the computer to the Ethernet port of C-75. 2. Configure the LAN IP address on the computer in the subnet 192.168.1.0/24. 3. SSH to IP address: 192.168.1.245 (factory default) 4. Log in to the CLI of the device using default credentials. 5. Configure server discovery on the device. 6. Configure a static IP address on the device. For example: Untagged VLAN 192.168.2.x/24. After completing this step you will lose the SSH connection. 7. Configure the LAN IP address in the range of 192.168.2.x/24 and again SSH to the address assigned in step 6. 8. Check the configuration settings. 9. Remove the crossover connection to the computer and connect the Ethernet port to the local switch. Configure IPv6 settings C-75 is IPv6 capable. Use the set ipv6 config command to configure advanced options such as DHCP settings, auto negotiation, and manual configuration. Enable auto negotiation to discover IP address automatically. Enable DHCP settings to obtain addressing as well as more information, such as the DNS address from DHCP server in the network. Enable manual configuration to provide manual IPv6 address as well as IPv6 default gateway. How to configure Communication Key or Passphrase C-75 Installation Guide 19 To configure the communication key or passphrase kindly refer to Appendix A: AP-Server Mutual Authentication for further details.

C-75 Troubleshooting Following are the troubleshooting guidelines for C-75. Symptoms Wi-Fi: any Ethernet: fast blink Power: solid orange Diagnosis Solution The device 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 device is connected. If the device still fails to get a valid IP address, you can reboot it to see if the problem is resolved. The Ethernet cable is loose. The device is probably disconnected from the network. Ensure that the Ethernet cable is connected. Ensure that the server is running and is reachable from the network to which the device is attached. If there is a firewall or a router with ACLs enabled between the device and the server, ensure that the traffic is allowed on UDP port 3851. Wi-Fi: any Ethernet: slow blink Power: solid orange Unable to connect to the server Use the server IP-based discovery and ensure that you have correctly entered the DNS name, wifi-security-server, on the DNS server. Also, ensure that the DNS server IP addresses are either correctly configured on the , or are provided by the DHCP server. It is also possible that the AP is unable to connect to the server because it has failed to authenticate with the server. In this case, an 'Authentication failed for ' event is raised on the server. Refer to the event for recommended action. C-75 Installation Guide 24 Appendix A: Access Point (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. All communication between the AP and server from this point on is encrypted using the session key. The AP and server are shipped with the same default value of the shared secret. The CLI commands are provided on both server and AP for changing 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. C-75 Installation Guide 25
