Three Stage Installation
The procedures for setting up a three stage installation are essentially the same
as for a two stage installation. With 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 KH98 units
needed to control them is provided on page 51.
Note: 1. See Notes 1 and 2 at the beginning of the Two Stage Installation
section.
2. KH98 units cannot be cascaded beyond the third level.
To set up a Three Stage installation, do the following:
1. Complete a Two Stage installation. See page 10 for details.
2. Turn off the power to all the devices you will be connecting up, including
all devices on the Second Stage installation.
3. Use a KVM cable set (described in the Cables section, page 3), to connect
any available KVM Port on the Second Stage unit to the Console Port
connectors of the Third Stage unit.
4. Use KVM cable sets (described in the Cables section, page 3), to connect
any available KVM port on the Third Stage unit to the Keyboard, Video,
and Mouse ports of the computers you are installing, as shown in the
diagram on the next page.
5. Plug the Cat 5 cable that connects the KH98 to the IPMI management
LAN or IPMI enabled server.
6. Plug the power cord that came with this package into the KH98's Power
Socket, and then into an AC power source.
7. Repeat the previous steps for any other Third Stage units you wish to
connect.
8. Power on the monitor.
9. Power on the First Stage unit(s); next, power on the Second Stage units;
finally, power on the Third Stage unit.
