7. Installation
1
Make sure that power to all the devices you will be connecting—including all preexisting devices on the
installation—has been turned off.
2
Use the provided cable sets (HDMI cable, USB 3.0 cable, and audio cable) to connect the First Stage unit to the
console ports of the Second Stage unit.
Note:
Plug the USB Type-A connector into the lower USB (keyboard) port in the Console section (they are both marked with a
similar icon to remind you of the correct USB port).
3
Using another provided cable set (HDMI cable, USB 3.0 cable and audio cable), plug the HDMI connector into any
available HDMI in the KVM Ports Section of the second stage switch, then plug the accompanying USB Type-B
cable and audio cable into their corresponding USB and audio jacks.
Notes:
• Verify all connectors are in the same KVM Ports Section (all in CPU 1, all in CPU 2, etc.) and that each port is marked with an
appropriate icon to indicate itself.
• The KVMs only support audio speakers. Do not connect a KVM cable’s microphone connector to the speaker ports.
4
At the other end of the cables from step 3, plug the HDMI cable, USB 3.0 cable and audio cables into their
respective ports on the computer.
5
Repeat steps 3 and 4 for any other PC systems you are installing.
6
For each Second Stage unit, plug the power adapter cable into its Power Jack, then plug the power adapter into an
AC source.
7
Plug the First Stage unit’s power adapter cable into its Power Jack, then plug the power adapter into an AC source.
8
Power on the computers.
Notes:
• The power-on sequence requires that Second Stage units be powered on first. After they are all powered on, the First Stage units
must be powered on next. Only after all KVM switches have been powered on in this sequence can the computers be powered on.
• The USB 3.1 hub cannot be accessed through the switch by computers on the second level of a cascaded installation.
• Make sure the computers and devices connected to the KVMs are also properly grounded.
7.3.3 Three-Stage Cascade Installation
The procedures for setting up a three-stage installation are essentially the same as for a two-stage installation. Using
the B024-H4U08 in a three-stage setup, as many as 512 computers can be controlled in a complete installation. A table
showing the relation between the number of computers and the number of switches needed to control them can be
found in section
14.1 B024-H4U08 and B024-H4U16 Connection Tables.
Notes:
• The B024-H4U08 cannot be cascaded beyond the third level and the B024-H4U16 cannot cascaded beyond the second level.
• The B024-H4U08 can only be cascaded with other B024-H4U08 units. The B024-H4U16 can only be cascaded with other
B024-H4U16 units
