3.7.3 User Account Settings
The user account settings page provides you a facility to change the user
names and passwords. The total of user accounts available are three, the
followings are the default settings:
1. “superuser” with default password of “12345678”. This login
account will have all the privilege to change and setup the system
parameters, including the system firmware upgrade.
2. “admin” with default password of “123”. This login account will
have all the privilege to change and setup the system parameters,
except the system firmware upgrade.
3. “guest” with default password of “123” ”. This login account will not
have the privilege to change and setup the system parameters.
It is highly recommended that you should change the password
immediately when the system is in the field and carries the data traffic, and
keep the password in a safe place.
If you somehow forget the password, you can change them back to the

frames to the remote converter and then check if the loopback frames are
successfully looping back. If there is no CRC error for all the loopback frames
and the frame number is the same as what it is sent, “Pass” will be shown as
the “Loopback Status”. The loopback test will interrupt the normal traffic path,
it will recover the normal traffic path after the loopback has completed.

display the card status, card present, card information and card location
information, respectively, as shown in the following figures. While the rest of
the commands are used to configure the system. It is important to note “#” in
the above command represents card number or slot number, where 1 ~ 15
will correspond to the converter in the slot. Number “0” is a global selection for
the slots, i.e. if number “0” is used in these commands, it means that slots 1 ~
15 will be selected at the same time.
The converter’s downstream and upstream rates are controlled by the
“card bw” command. The command requires three parameters, the first
parameter refers to the slot number where the converter resides in, and the
second and third one are the downstream and upstream rate setting,
respectively, for example “1+200” means the rate setting of “1M + 200 *128K”.
