Security Considerations: Ports, Certificates
The HC 404 system communicates using SSH protocol via port 4523 rather than Telnet
on port 23. This provides for more secure access to the unit and reduces the likelihood of
changes to configurations or operation. Port 23 is not supported by the HC 404 system.
Security certificates allow greater privacy and security by allowing communications between
the server and the device to be encrypted. You can use the default security certificate
that is factory-installed on the HCR 102, or you can replace it with one provided by your
organization (see
Secure Sockets Layer (SSL) Certificates
Things to Do After Installing GC and Before Starting a Project
•
Read the
Global Configurator Help
file for details and step-by-step procedures on
how to start a GC Professional or GC Plus project and perform basic setup tasks for a
HCR 102 receiver. The help file provides a wealth of information on settings and how
to use the software. It includes examples of how to use the features of GC and step by
step instructions for typical configuration tasks.
•
Obtain network addresses and related information from your network administrator.
•
Set up the IP address for the HCR 102. See
page 22 for an overview of how to set up the network properties of the unit. For
details, see the GC help file or Toolbelt help file, which contains instructions on how to
set the IP address, gateway IP address, subnet mask, mail server IP address, domain
name, Web port, SMTP username, and SMTP password so that the HCR 102 is able to
communicate with the network.
Using GC: Helpful Tips
Resources and Notes
•
The
HC 404 Setup Guide
, shipped with the unit, includes a quick reference to the front
and rear panel features, and covers basic hardware installation.
•
on page 10 in the “Hardware Features and Installation” section of this
guide for features and settings for the ports you are configuring.
•
If you plan to configure the system at the installation site, Extron recommends
downloading drivers for all the devices in the installation
before
you go out to the site
•
The Global Configurator project file (*
.gcpro
or *
.gcplus
) contains configuration
settings and it can be saved to a directory or folder for backup or for installation on
another HCR 102. Saving a configuration is recommended before you perform a
firmware upgrade.
•
The HCR 102 can be set up to allow configuration access only to administrators to
prevent other users from making changes to settings, events, and controls.
•
IP address, subnet mask, and gateway address are required during network setup of
the unit.
•
The unit name is any name (for example, Room730-HCR102 or ConfRmSystem) that
you want to use to label a specific HCR 102 unit. The default is a combination of the
product name and part of the hardware (MAC) address. This can be changed to your
choice of alphanumeric characters and hyphens (-). The following rules apply:
•
Spaces are not permitted within the name of a unit or at the start or the end of a
name.
•
Underscores ( _ ) are not permitted.
