Fan assembly
The three fan assemblies are hot-swappable if replaced one at a time. They are identical and fit
into any fan slot.
Fabric OS identifies the fan assemblies as follows (viewing the switch from the port side):
• Fan assembly 1 is on the left.
• Fan assembly 2 is in the center.
• Fan assembly 3 is on the right.
To determine if a fan assembly requires replacing, do any of the following:
• Check the system status LED ( Figure 11 ). If the fan status LED is not on, verify that the fan is
seated correctly. If the light does not turn green, the fan assembly may need to be replaced.
• In 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 9507 RPM
Fan 2 is OK, speed is 9246 RPM
Fan 3 is OK, speed is 9337 RPM
