HP B-series 16Gb FC Switches Hardware Reference Guide

Determining the need to replace a fan
Use one of the following methods to determine the status of the fans:
• Check the fan status LED. See “LEDs” (page 47) for more information.
• In Web Tools, click the Power Status icon.
• At the command prompt, enter the fanShow command to display the fan status.
NOTE: Fans 4 and 5 are integral to the power supplies. These fans typically operate at
approximately 12,000 RPM; while the system fans typically operate at approximately 2,000 RPM.
If there is a problem with fan 4 or 5, see “ Replacing an HP StoreFabric SN6500B 16Gb FC
Switch power supply” (page 53).
