Important:
All four fans must be installed at all times to ensure proper ventilation. If a fan fails, replace it
as soon as you can but leave it in place until you do. Leaving a fan bay unpopulated impairs
the ability of the remaining fans to cool the chassis.
Procedure
1. Check the Fan LED on the front of the chassis. Solid green indicates that all fan modules
are operating normally. Blinking amber indicates that a fan module failed.
2. Enter the following command to determine which fan module failed.
show sys-info fan
This command shows the status of each fan module:
up
,
down
, or
Not Present
when a
fan is removed.
3. Remove the fan module that failed by loosening the two thumb screws and pulling the fan
module out of the chassis.
4. Insert the new fan module into the chassis.
Important:
You can hot swap fan modules while the switch is operational.
5. Verify that the fan module is fully seated in the chassis and secure it with two thumb
screws.
6. Enter the following command to check the temperature sensors inside the switch.
