Servicing Filler Panels
Unused I/O module slots ship with installed filler panels. These filler panels do not contain active components, so you can replace them while the switch is powered on.
 | Caution - To maintain the proper air flow when the switch is powered on, all filler panels and I/O modules must remain in the switch unless you are in the process of installing or servicing an I/O module or filler panel. |
| Caution - Remove only one filler panel or I/O module at a time, and replace the filler panel or I/O module within one minute. |
