  If the yellow LED flashes 6 times on your DSC Cell Phone, this indicates an Ethernet trouble. First, check with your ISP to confirm that Internet service is active in your area. Ensure your Ethernet cable is securely inserted into the RJ45 jack of the communicator and the hub/router/switch. Also, check the link light on the hub/router/switch is ON. If the link light is OFF, restart the hub/router/switch. If DHCP is used, ensure that the unit has an assigned IP address from the server. In Section [851] [992] verify a valid IP address is programmed. If not, contact the network administrator. If the problem persists, replace the Ethernet cable and RJ45 connector.
