3.1. KVM Switch Operation
3.1.1. Password Security
When you power on the U8/16 it will ask you for a user name and a password. The default
user name and default password for both is eight zeros –“00000000”. Please key in eight
zeros in the password field. You may use the “0” from the standard keypad but not from the
numeric keypad.
Note:
Please don’t change the password until you are familiar with the operation of the OSD
menu – i.e. keep the default password “00000000”. Otherwise, if you forget the password, you
will need to send the switch back to LINDY for maintenance to clear the password.
The U8/16 OSD security feature offers up to 8 users + 1 SUPERVISOR.
A user specific access control list is available from the OSD of the KVM switch and can be
configured by the supervisor.
3.1.2. Hot Plug Support
The U8/16 supports a “Hot Plug” function for easy addition or removal of computers. The user
can arrange or maintain the computers and daisy chained KVM Switches as follows:
a. A computer can be disconnected and reconnected to the same or a different port of the KVM
switch without having to power it off as long as it is currently not connected to the console. In
most cases the PS/2 mouse and keyboard signals will be maintained and will not be lost.
b. The mouse driver of the computer has to support the hot plug function or the computer may
need to be rebooted when it is reconnected.
c. You can unplug your mouse or keyboard from the console port and plug it back in at any
time. You should not use different types of mice when performing this.
d. A SLAVE KVM switch can be added or removed at any time, but after adding or removing a
switch it may be required to reset all of the KVM switches. But you DO NOT need to reboot
the computers.
Please note:
Some Operating Systems such as certain Unix versions are unable to
support the “Hot Plug” function. If you Hot Plug when using this kind of O.S., it may cause
unpredictable operation or may shut down the computer. Before attempting to use the Hot
Plug feature, please check that the O.S. and mouse driver support this function.
Important note:
Your monitor will only display one PC signal at any one time. All
keyboard and mouse commands are sent to this PC only. After initial power up, port 1 is
active by default.
When a PC is connected to the currently selected port and it is not switched on,
or is in sleep mode, the monitor will not display any signal.
