Replacing Frame Ventilation Fans
Put the multiviewer into operation and confirm that the critical temperature and fan alarms
remain inactive.
Replacing Frame Ventilation Fans
The main cooling fans on the rear of Kaleido-MX (1RU) frames may be replaced in case of
failure. Replacement part number is #0969-2100.
To replace a frame ventilation fan in a Kaleido-MX (1RU)
1 Remove the two screws that secure the fan assembly to the frame, and pull the fan
assembly straight out of the frame.
Retain the screws, as they will be used with the replacement fan.
2 Slide the new fan assembly into the opening on the rear panel, pushing it straight in,
and ensuring that the connector on the assembly mates with the socket in the frame.
The two ventilator fans are mounted at different angles, as shown in the above figure.
3 Align the circuit board on the fan assembly with the
notches in the edge of the rear-panel opening (see
arrows in figure at right) to ensure the correct
alignment.
The socket into which the circuit board connects is
hidden from view by the fan assembly during
installation and there is no guide to ensure that
they are aligned. The easiest way to make sure that
the connector and socket have mated properly is to
install the fan with the frame power turned on. You
will hear the fan start up when the connection is
made.
4 Use the two screws you retained from the old fan, to
secure the new fan assembly to the rear panel.
