Revision 2.4 WebRelay-Quad™ Users Manual
Installation Guidelines (Read Before Installing)
Do not open the WebRelay-Quad™ enclosure. This will void the warranty.
━ This unit must be installed by qualified personnel.
━ This unit must not be installed directly outdoors.
━ This unit must not be used for medical, life saving purposes, or for any purpose where its
failure could cause serious injury or the loss of life.
Notes about security:
By design, WebRelay-Quad™ is very secure. It does not support terminal or file transfer programs
such as telnet, ftp, ssh, etc. This means that it is not possible for someone to ‘break in’ to
WebRelay-Quad™ and access other devices on your local network. WebRelay-Quad™ does not
support remote firmware updates which means that it is not possible for someone to remotely
install malicious software. The simplicity of WebRelay-Quad™ makes it a very secure device. As
with any device to be installed on a network, there are some security precautions that should be
observed. If WebRelay-Quad™ is installed on the Internet, it is recommended that passwords be
enabled for the control page. Make sure secure passwords are used. Passwords should be at
least 8 characters in length and should be a combination of upper case letters, lower case letters,
and numbers. Don’t use passwords that would be easy to guess. For additional security, a
firewall may be used to limit access only to selected IP addresses. Another option may be to set
up a Virtual Private Network (VPN) between the network where WebRelay-Quad™ resides and
the client machine (web browser, second WebRelay-Quad™, etc.).
Final installation note. This ControlByWeb™ product supports connection to 10Mbps and
100Mbps networks. Although 100Mbps networks are faster, the amount of data transferred to and
from this device is very minimal and little if any performance increase will be gained by setting it to
100Mbps. There are advantages however, to operate this device at 10Mbps. At 10Mbps, less
power is required, the unit runs cooler, and the lifetime of the product will be extended.
