Cautions and Warnings
CAUTION: Disconnect all power cords before servicing.
WARNING: Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries
according to the battery manufacturer’s instructions.
WARNING: Removal of equipment top cover is to be done only by trained service person(s).
Replacing a Power Supply
The PA-4000 Series firewall has two hot-swappable power supplies. Both power supplies should be
connected during normal operations. If the system detects a loss of power, either due to loss of power
connection or failure of the power supply, the power supply LED located above the power plug and the
front panel PWR LED both turn red, and a continuous audible alert is generated.
To replace the PWR1 or PWR2 power supply:
1. While the PA-4000 Series is running, unplug the power cord from the power supply that you need
to replace, and unscrew the screw knob.
2. Use the handle to slide the power supply out of the device, as shown in Figure 8.
3. Slide a replacement power supply into the device, and attach with the screw knob. Tighten the
screws more with a tool after initial and subsequent access to the power supply.
4. Connect the power cable to the power supply and to an AC power source.
