Enable or Disable the DHCP Client
This mode toggles between DHCP enabled and DHCP disabled. This can also be carried
out from the
Network
screen of the Setup menu (see page 12) or the
Network
screen of
Toolbelt (see the Toolbelt Help File at
www.extron.com
).
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 Power LED blinks three times.
•
If DHCP was disabled, it is now enabled. The Power LED blinks six times.
NOTES:
•
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.
