4.1.3 Username and Password
With a null-modem cable connecting the switch to a suitable configuration device, a
login screen similar to that of Figure 1 is displayed. However, your screen will identify
your specific switch model number and the version of your firmware.

By default, both of the Username and Password strings are “blank”. To retain a blank
Username, press the “arrow down” button while the cursor is in the Username box. To
use a blank Password, press “Enter” while the cursor is in the Password box.
Both Username and Password are case sensitive and the number of characters in each
string can range from 0 (blank) through 10. Once these strings have been modified,
future access to the management features of the switch will be denied unless the user
re-enters the correct information. However, should either of these strings be forgotten,
a means exists to reset them to their default values. The “reset” process consists of
shorting pins 2 and 3 of the Console Port (Figure 2) for 10 seconds during boot. This
will reset ONLY the Username and Password and ONLY for this current login session
— the remaining parameters are not changed. After logging in, the username and
password should be changed and saved to EEPROM to overwrite the forgotten
username and/or password. If the username and password are not changed, the reset
process must be repeated on power cycle.

After the Username and Password are accepted, the Main Menu (Section 4.2) appears.
