# Powering Down

If you need to power down or remove the SRP module, first enter the halt command to temporarily suspend the system's operation. See JunosE System Basics Configuration Guide, Chapter 5, Managing the System for more information.

| Caution: If you do not use the halt command before removing or powering down an SRP module, the system's NVS card might become corrupted.

If you shut down the system improperly, it runs an investigation of the file allocation table (FAT) the next time it reboots.
