Enable or Disable the DHCP Client
This mode toggles between DHCP enabled and DHCP disabled. This can also be carried out
from the
screen of the Setup menu (see page 27) or the Network screen of Toolbelt
(see the
Toolbelt Help File
at
Activation
To enable or disable the DHCP client for the LAN port:
1.
Press the
Reset
button five times (consecutively).
2.
Release the button. Do not press the button within 3 seconds, following the fifth press.
Result
•
If DHCP was enabled, it is now disabled. The Reset LED blinks three times.
•
If DHCP was disabled, it is now enabled. The Reset LED blinks six times.
NOTES:
•
DHCP toggle mode is supported on firmware version 3.0 or higher.
•
By default DHCP is off and the unit uses a static IP address.
•
When you disable DHCP, the unit reverts to using the previously-set static IP address.
Secure Sockets Layer (SSL) Certificates
Extron TouchLink Pro control systems ship with factory-installed SSL certificates created by
Extron. If you want or are required to use a different SSL certificate at your installation site, then
you can use system utilities in the Toolbelt software to change the SSL certificate at any time.
The Toolbelt Help File provides instructions on how to apply an SSL certificate to a controller.
NOTES:
•
You must run Toolbelt as an administrator.
•
Some certificates require a passphrase that is created when the certificate is created. If
a passphrase is required, you must enter that passphrase before uploading and applying
the certificate.
These devices support standard OpenSSL certificate encodings such as .pem (Privacy-
enhanced Electronic Mail) and .der (Distinguished Encoding Rules) file types. PEM file types are
ASCII encoded and are the required format for uploading to the Extron control product. DER file
types are binary encoded and can typically have several file extension variations, such as .crt and
.cer. There are many standard tools that can convert from DER to PEM file encodings if needed.
NOTE:
A DER format file must be converted to PEM encoding before uploading it to the
button panel, control processor, or collaboration receiver.
To properly create the certificate for uploading to Extron control devices, ensure that the
certificate file meets the following requirements:
•
contains X.509 certificate information
•
contains public and private keys
•
uses PEM encoding
NOTE:
ITU-T standard X.509 covers aspects of public key encryption, digital cryptography,
certificates, and validation.
Contact your IT administrator for more information on what tools and policies are required to
obtain or create the SSL certificate and, if necessary, the corresponding passphrase.
