configuration will be lost. This can be offset
in a positive way by returning the Model
5401A to a known configuration, a point that
might aid in troubleshooting an issue. Refer
to Appendix F for a list of the default values.
Lost User Name and/or
Password
As is covered in detail in other sections
of this guide, gaining access to the Model
5401A’s configuration menu webpages
requires entering the correct user name
and password. If the default entries, both
of which are guest, are stored for use then
they will display on the Login menu web-
page. Pressing the Log In button on that
webpage will then access the Main configu-
ration webpage. If either or both the user
name and the password have been config-
ured to be something other than guest (the
default) then nothing will show in the fields
associated with the login menu webpage.
If knowledge of the stored user name and/or
password is “lost” then the Model 5401A
includes a “backdoor” to allow access. But
as a security measure physical access to
the unit is required to utilize that access
method; there is no means to access the
unit via an Ethernet port without knowledge
of the user name and password. The exact
process of accessing the Model 5401A’s
configuration webpages without knowledge
of the user name and/or password is de-
tailed in Appendix H, located at the end of
this guide.
