3 Managing the Brocade 5100 2. Use one of the following methods to determine whether a fan requires replacement: • Check the system status LED (see Figure 4 on page 18 for location of system status LED). If the system status LED is flashing amber and green, it could mean the fan has failed. The green power supply/fan LED will also flash in the event of failure. Check the management interface and the error log for details on the cause of status. • In Advanced Web Tools, check the Fan Status icon background color. It will be either yellow or red if the fan has failed. When the fan is functioning correctly, the background color is green. • Type the fanShow command at the command prompt to display fan status as shown below: switch:admin> fanshow Fan 1 is OK, speed is 7105 RPM Fan 2 is OK, speed is 7258 RPM For further information on replacing the power/fan units, see the Brocade 5100 Power Supply and Fan Assembly Replacement Procedure. Managing the Brocade 5100 You can use the management functions built into the Brocade 5100 to monitor the fabric topology, port status, physical status, and other information to help you analyze switch performance and to accelerate system debugging.
