Replace a Fan Spinner
The following sections describe how to remove or install a Fan Spinner:
Remove a Fan Spinner
• You must wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling
modules.
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
Caution
Ensure to complete the Fan Spinner replacement within 3 minutes as removing a Fan Spinner also removes
the fan modules.
We recommend that you remove or replace the Fan Spinner and fan modules as a single unit to save the
replacement time.
1. If you are replacing a Fan Spinner, open the packaging for the new module and inspect it for damage.
Note
2. Remove the Fan Spinner that you are replacing by following these steps:
a. Loosen the captive screws on both sides of the Fan Spinner.
b. Rotate the handles outwards until they stop (see Callout 2 in the following figure).
c. Use the ejector handles to pull the module a couple of inches (about 5 cm) out of the slot until it stops.
Note
Ensure to close both the ejector levers at the same time so that the SC sits properly in the SC slot.
Tighten the captive screws on the SC within 10 seconds. If you can't replace an SC within three
minutes, we recommend that you leave the SC in the chassis until you are ready to replace it.
If the Fan Spinner is damaged, contact your customer service representative and stop this replacement process
until you have an undamaged Fan Spinner to install.
Hold the front of the Fan Spinner with one hand and place your other hand under the Fan Spinner to support
its weight.
