Power Supply Installation and Replacement
The Firebox has two redundant hot-swappable power supplies. If a power supply fails, you can replace it
while the Firebox is powered by the other power supply.
To replace a power supply:
1. Use the power indicator to identify the failed power supply. If the device is powered on, the
indicator on the failed power supply flashes red after you reset the audible alarm.
2. Disconnect the power cable from the power supply you want to replace.
3. Find the release tab, located on the left side of the power supply.
4. Firmly push the release tab to the right, while you use the power supply handle to pull the power
supply out of the slot.
5. Slide the replacement power supply into the open slot.
6. Press firmly on the face of the power supply until it is flush with the back of the Firebox. If the
replacement is successful, the power indicator light for the new power supply is green.
You can purchase a replacement power supply from an authorized WatchGuard reseller.
