Inserting a New Fan Assembly

Use the following steps to install a fan assembly in the RUCKUS ICX 7550 switch.

Installing a Fan Assembly

1. Fan assembly slot
2. Fan assembly
3. Captive screw

1. If replacing a fan assembly:
   1. Using a Phillips screwdriver, unscrew the captive screw on the fan assembly.
   2. Remove the fan assembly from the chassis by pulling the handle on the fan assembly out and away from the chassis.
   3. Ensure that the replacement fan assembly has the same part number and airflow label as the fan assembly being replaced.
2. If installing a new fan assembly into a slot covered with a filler panel:
   1. Using a Phillips screwdriver, unscrew the captive screw on the filler panel.
   2. Remove the filler panel.
3. Before opening the package that contains the new fan assembly, touch the bag to the switch casing to discharge any potential static electricity. It is recommended that you wear an ESD wrist strap during installation.
4. Remove the fan assembly from the anti-static shielded bag.
   Caution: Do not force the installation. If the fan assembly does not slide in easily, ensure that it is correctly oriented before continuing.
5. Holding the fan assembly level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector.
6. When you are sure the fan assembly has properly engaged the connector, tighten the captive screw to secure the fan assembly in the slot.
   Note: The fans are controlled automatically by the device.
7. Verify correct installation by running the show chassis command.

When a fan assembly is installed in a slot, the power LED on the fan assembly lights up green to confirm that the fan assembly is correctly installed and running. Refer to LED Patterns.
