6 Maintenance
6.1 Cleaning the air filter
Occasionally, the air filter has to be removed and properly cleaned in order to maintain proper ventilation. To
remove and clean the air filter, follow these directions:
1. Remove the front panel door by first removing the locking screws using a philips screwdriver and rotating
the quarter-turn latch toward the center of the front panel.
2. Remove the air filter located at the bottom of the front panel.
3. Use warm running water to clean the air filter. Make sure the air filter is dry before reinstalling it.
4. When replacing the air filter, make sure it completely covers the front panel air vents.
5. Replace the front panel door and replace the locking screws to prevent unauthorized access.
6.2 Replacing a defective power supply
In the event of a power supply failure, the unit will switch to the redundant power supply for its power source. An
alarm will appear on the Kaleido-K2 output screen, until it is manually reset through the Kaleido software. It is not
neccessary to turn off the unit before replacing the defective power supply.
To replace a defective power supply, follow these steps:
1. Switch off the defective power supply and disconnect the power cord.
2. Remove and keep the screw that retains the defective power supply (item 4 on figure 3.3.1).
3. Pull on the handle and remove the defective power supply.
CAUTION! The power supply may be very hot. Wear gloves if necessary.
4. Replace the new power supply, making sure to insert it the correct way (the retaining tab must be on
the left-hand side).
5. Replace the screw and power cord.
6. Switch on the new power supply.
6.3 Replacing a defective fan
Kaleido-K2 uses a cross flow fan for cooling the modules. This fan may be replaced even if the unit is installed in
the equipment rack. To replace the fan, refer to figure 6.3.1 and follow these steps:
1. Turn off the unit using the front On/Off switch.
2. Remove all the connector panels at the rear. It is not necessary to unplug the cables from the connector
panels.
3. Unscrew the fan bracket and pull gently to access the power connectors situated at the rear of the midplane.
4. Unplug the fan connector.
