Replacing the front panel
You may need to replace the front panel of a node if the font panel become damaged or if there is an issue with the
integrated LCD.
Note: Removing a front panel does not require powering down the node. However, you may need to restart the
LCD on the front panel through the command-line interface when you replace the front panel.
1. Place one hand on each side of the front panel and gently pull forward to remove the front panel.
2. Align the new front panel with the ear brackets on the node and snap the front panel into place.
