Kaleido-X (7RU)
Hardware Description & Installation Manual
• XML Gateway operations are unaffected, except for operations involving video, audio
or metadata exchange between frames.
• If router expansion is enabled, then the Router manager can be used to change
crosspoints on Frame B.
Losing Expansion Cards
Failure of an expansion card only impacts the exchange of sources and data between
frames. It does not impact the display of sources and data that are within the same frame. If
one or both expansion cards are lost (e.g. a card is removed from one of the frames), the
result is identical to that of losing inter-frame connectivity, as described above.
Expansion cards are hot swappable. A complete reboot of the card takes approximately 10
seconds.
Recovering From a Failed Downgrade
If you downgrade a Kaleido-X expansion system to version 2.20 without first splitting the
frames as described on
page 67 , neither frame will reboot properly or be accessible via
XAdmin (the frames will have an invalid frame type and duplicate IP addresses).
To recover from a failed downgrade
1 Power down both frames, and remove expansion cards and cables.
2 Power up Frame A.
3 Open XEdit, and then export a version 2.20 Kaleido-X (7RU) database to Frame A.
4 Reboot Frame A, and then power it down.
5 Power up Frame B with only one KXO card installed
6 Open XEdit, and then export a version 2.20 Kaleido-X (7RU) database to Frame B.
7 Reboot Frame B.
8 Open XAdmin from Frame B, and change its IP address and System name.
9 Reboot Frame B, and then reinsert any KXO cards you had removed in step 5 .
10 The firmware on these cards will be automatically downgraded to version 2.20.
11 Power up Frame A. Its KXO cards will have already been downgraded to version 2.20 by
the original attempt (i.e. before splitting the frames).
Recovering an Expansion Frame
There are some situations where a Kaleido-X (14RU) expansion system may stop working
normally, or become partially unresponsive. It is possible to recover from such situations by
first splitting the two frames, and then rejoining them in an expansion configuration.
IMPORTANT
The following procedure applies to the splitting of an expansion frame
that is in an error condition or otherwise not working normally.
If the expansion system to be split is working normally, then refer to
Recovering From a Failed Downgrade , on page 71.
