4.1.4 Username and Password
Each time the switch is accessed by a web browser, the Login screen of Figure 8 will
appear. You are strongly encouraged to change the Username and Password.
Figure 8 — Login Screen
On models with a Console Port, you can reset login strings to
their default (blank) values by shorting pins 2 and 3 of the
Console Port (Figure 9) for
10 seconds during boot. This resets
only the Username and Password and only for the current
login session — other parameters are unchanged. Then login
strings should be changed and
saved to overwrite the old values,
or the reset must be repeated when a power cycle occurs.

4.1.5 Restoring Factory Default Settings
On models with a Console Port, this can only be done via Console Access. See the
Main Menu options in the Software Manual for Console Access for the procedure. The
Software Manual for Console Access available at:
On the EISK_M Series, you can reset the switch to ALL of its factory default settings
via a hole on bottom of the unit. Use a paperclip or similar tool to press the recessed
button for at least 3 seconds while the unit is powered. Then release the button and
remove power for 3 seconds. Restore power and the unit will now use its factory default
values of IP address, subnet mask — and Username and Password, both of which will
be blank.
CAUTION:
This action erases ALL user-configured information.
