Known issues
FW 0.50
The Network Module enables the DHCP Server automatically when a factory default is performed on the
system. The DHCP Server may present network conflicts.
See Disabling the Network Module’s DHCP Server procedure below.

Disabling the Network Module’s DHCP Server
The CA300’s Network Module can operate as a DHCP Server to make setup easier. This server is enabled by default,
whenever the system is factory defaulted, to streamline the network configuration process. However, this may create
unintended network conflicts. To avoid this, we recommend that the DHCP Server be disabled by following the
procedures below:
1. Perform a factory default to the CA300 system.
2. Login to the Network Module to disable the DHCP Server.
Factory Defaulting the CA300
NOTE: Make sure the system is not connected to the wired network when the system is factory defaulted. When the
system is defaulted, this will enable the Network Module’s internal DHCP Server.
To remove ALL CA300 system configuration settings, press and hold the following buttons at the same time for 5
The source selections LED’s will light up one by one and blink three times before the entire system reboots. Once the
system has fully booted up (approximately 2.5 minutes), it is ready for setup and configuration.
