Managing Passwords
Networking allows multiple users in both remote and local locations to use the
EthernetBlaster II communications cable, increasing the productivity in prototyping
and debugging. However, because of this flexibility, it is necessary to limit and control
user access of the provided password service in the EthernetBlaster II
communications cable setup.
The EthernetBlaster II communications cable contains two types of passwords—an
administrative password and a Quartus
® II remote connection password.
■ The administrative password is the master password used to enter the
EthernetBlaster II administrative web page. If you know the administrative
password, you have full control of settings and the ability to modify both the
administrative password and the Quartus II remote connection password.
■ The Quartus II remote connection password allows clients to add the
EthernetBlaster II hardware to their Quartus II Programmer hardware setup. This
password is used to control who has access to the EthernetBlaster II
communications cable. However, they do not have access to the EthernetBlaster II
administrative web page and cannot modify the settings or change passwords.
1 When you change the Quartus II remote connection password, client systems using
the EthernetBlaster II communications cable must remove the hardware from their
Quartus II Programmer hardware setup. For more information, refer to
“Removing
the EthernetBlaster II Hardware from the Quartus II Software” on page 1–12 . The
hardware then must be added back into the Quartus II software. For more
information, refer to
“Setting Up the EthernetBlaster II Hardware in the Quartus II
Software” on page 1–11 .
