Port Configuration; Status - Black Box 12-Port 1000BASE-TX L2 Managed PoE Switch User Manual

12-Port 1000BASE-TX L2 Managed PoE Switch with 2 SFP Dual Media Ports
an SNMP or Telnet user interface, VSM is only available in a Web user interface (UI). While one switch is the
Master, two rows of buttons for a group device will appear on the top of its Web UI. Press the buttons to
connect the group devices' Web UI in the same window without logging in to the corresponding devices.
The top-left button is only for the Master device. The background color of the button you press will be changed
to represent that the device is under your management.
If you log into the switch via the console, the grouping will be removed temporarily.
The group device is shown as station address (the last number of IP Address) + device name on the button (for
example, 196_LPB200A); otherwise it will display "----"if no corresponding device exists.
Once the devices join the group successfully, then they can only be managed via the Master device, and a user
won't be able to manage them individually via Telnet/console/Web.
Up to 16 devices can be grouped for VSM; however, only one Master is allowed to exist in each group. For
Master redundancy, you may configure more than two devices as the Master device; however, the Master device
with the smaller MAC value will be the Master one. All 16 devices can become a Master device and back up each
other.
