Two Stage Installation
To control even more servers, up to 16 additional KVM switches can be
cascaded from the KVM ports of the original KVM over IP switch. As many
as 128/256 servers can be controlled in a complete two stage installation.
In a cascaded installation, the KVM over IP switch is considered the
First
Stage
unit, the cascaded switches are considered
Second Stage
units.
Note:
The cascaded KVM switch shown in the example is the KH1516.
See
, page 272, for a list of other switches.
To set up a two stage installation, refer to the diagram on page 23, and do the
following:
1. Make sure that power to all the devices you will be connecting, including
all preexisting devices on the installation, are properly grounded and have
been turned off.
2. Use Cat 5e cable to connect any available KVM Port on the First Stage
unit (the KVM over IP switch) to a KVM Adapter Cable (as described
under
3. Plug the adapter cable’s KVM connectors to the Keyboard, Video, and
Mouse Console ports of the Second Stage unit.
Note:
The distance between the
First Stage
unit and the
Second Stage
unit
must not exceed 40m or 50m based on the KVM adapter cable used.
4. Use KVM cable sets (as described in the Cables section of the cascaded
KVM switch’s User Manual), to connect any available KVM port on the
Second Stage
unit to the Keyboard, Video, and Mouse ports of the servers
you are installing.
5. Plug the power cord that came with the cascaded KVM switch into its
Power Socket, and then into an AC power source.
6. Repeat these steps for any additional
Second Stage
units you wish to
connect.
7. Power on the
Second Stage
unit(s), then power on the
First Stage
unit.
8. Turn on the power to all the servers.
Note:
The Power On sequence requires that all
Second Stage
switches be
powered on first. After all
Second Stage
switches are powered on,
