OnCell G3111/G3151/G3211/G3251 Series User’s Manual System Management Settings
12-15
For all changes to the OnCell G3111/G3151/G3211/G3251’s password protection settings, you will
first need to enter the old password. Leave this blank if you are setting up password protection for
the first time. To set up a new password or change the existing password, enter your desired
password under both New password and Confirm password. To remove password protection,
leave the New password and Confirm password boxes blank.
ATTENTION
If you forget the password, the ONLY way to configure the OnCell G3111/G3151/G3211/G3251
is by using the reset button on the OnCell G3111/G3151/G3211/G3251’s casing to load the
factory defaults.
Before you set a password for the first time, it is a good idea to export the configuration to a file
when you have finished setting up your OnCell G3111/G3151/G3211/G3251. Your configuration
can then be easily imported back into the OnCell G3111/G3151/G3211/G3251 if you need to
reset the OnCell G3111/G3151/G3211/G3251 due to a forgotten password or for other reasons.
Please refer to the section on Configuration Import/Export earlier in this chapter for more details.
Certificate
Ethernet SSL Certificate Import
SSL certificate is used to ensure the website you are accessing is the one you trust, and to encrypt the
data transmitted between you and the website. The SSL certificate contains unique, authenticated
information about the certificate owner. It is issued by a Certificate Authority (CA), such as Verisign,
that verifies the identity of the certificate owner.
The OnCell G3111/G3151/G3211/G3251 will generate a new SSL certificate whenever a new IP is
used. However, the SSL certificate is issued by the OnCell itself. If you would like to import an SSL
certificate issued by a primary CA, you can do it from the “Ethernet SSL Certificate Import” page.
