Fan Assembly Features

The Catalyst 4500-X series switch chassis has five fan assemblies located in individual bays at the back of the chassis. Each fan assembly can be removed and replaced individually. The Catalyst 4500-X switch normally operates with all five fans running. In the event of a single fan assembly failure, the chassis can continue to operate normally for extended periods of time. However fan redundancy is no longer available. In the event that another fan fails, the chassis shuts down. We recommend that you replace a failed fan assembly as soon as possible in order to maintain fan redundancy. Figure 1 shows the major features of a fan assembly.

The fan assembly has one unlabeled LED mounted on the lower right corner of the fan assembly front panel. (See Figure 1.) The LED provides the status of the individual fan assembly.

Removing a Fan Assembly

---

Note The chassis can operate normally for extended periods of time on four fan assemblies. However, the chassis no longer has fan redundancy. An additional fan assembly failure (two fan assemblies inoperative) will shut the system down. We recommend that you replace a faulty fan assembly as soon as possible in order to maintain five operating fan assemblies and fan redundancy.

---

To remove a fan assembly, follow these steps:

---

Step 1 Grasp the two fan assembly release levers between your thumb and forefinger and squeeze to release the fan assembly from the chassis. (See Figure 2.)

Step 2 Slide the fan assembly out of the chassis and set it aside.

Figure 2 Removing a Fan Assembly

Step 3 Install the replacement fan assembly following the procedure in the next section.

---

Installing a Fan Assembly

To install a fan assembly, follow these steps:

---

Step 1 Remove the fan assembly from the shipping packaging and discard the packaging.

Step 2 Verify that the new fan assembly has the correct airflow direction (front-to-back or back-to-front) for your situation. The fan assembly release levers (see Figure 1), are color-coded burgundy for front-to-back airflow or blue for back-to-front airflow.

---

Note The chassis determines which airflow direction is correct by polling all of the fan assemblies and the power supplies. The airflow direction for all of the devices must be the same. If the airflow direction of the replacement fan assembly does not match the other fan assemblies airflow direction or the power supply airflow direction, the system software shuts down the power supply and generates an error message to the console.

---

Step 3 Position the fan assembly in front of the chassis fan assembly bay so that the fan assembly connector block is on top at the back of the assembly and the fan status LED is in the lower right corner of the fan assembly front panel. (See Figure 3.) Slide the fan assembly into the chassis.

---

Note The fan assembly is keyed to prevent incorrect insertion.

---

Figure 3 Inserting the Fan Assembly into the Chassis

Step 4 Press your thumb firmly on the pad between the fan assembly release levers to seat the fan assembly in the chassis. (See Figure 4.)

Figure 4 Seating the Fan Assembly in the Chassis

Step 5 The fan automatically starts once it is fully seated in the chassis. Visually verify that the fan is operating correctly by monitoring the fan assembly LED.
