Filler Panels
A filler panel is an empty metal or plastic enclosure that is installed at the factory or in the field into a server component slot that does not contain a functioning component. The filler panels ensure proper airflow through the system. Depending on the component configuration, the server can include the following types of filler panels:

 | Caution - When you remove a server component while the server is connected to power, insert a new component or filler panel within 60 seconds to ensure proper system chassis cooling. After you complete cold-servicing, ensure that all fillers are in place before connecting the server to power. |
