Fans

Each power supply is capable of providing all of the switch’s power needs. During normal operation, each power supply provides half of the demand. If one power supply goes offline, the second power supply steps up and provides the difference.

The power supplies are hot swappable and interchangeable. Hot swappable means that you can remove and replace one power supply while the switch is in operation without disrupting service.

Each power supply has two status LEDs: an Output Power LED (green) and an Over Temperature LED (amber):

The Output Power LED illuminates to indicate that the power supply is producing DC voltage at the proper levels.

The Over Temperature LED illuminates to indicate that the power supply is overheating. When a power supply overheats, the switch extinguishes the Output Power LED and shuts down the power supply. Refer to

Section 5 Diagnostics/Troubleshooting for information about troubleshooting over temperature conditions.

Fans

The switch is equipped with two fans as shown in Figure 2-10. If one fan should fail, the other fan is capable of providing the necessary cooling until the failed fan can be replaced. The fans are hot swappable and interchangeable. Refer to ”Fans” on page 6-4for information about removing and replacing the fans. Air flow can be front-to-back or back-to-front depending on the switch model.
