Installing the Hardware
This chapter describes how to install the PA-4000 Series firewall. For more information, refer to the
following topics:
•“Tamper Proof Statement” on page 9
•“Before You Begin” in the next section
•“Equipment Rack Installation” on page 10
•“Connecting Cables to the Device” on page 11
•“Connecting Power” on page 12
Tamper Proof Statement
To ensure that products purchased from Palo Alto Networks have not been tampered with
during shipping, verify the following upon receipt of each product:
•The tracking number provided to you electronically when ordering the product matches
the tracking number that is physically labeled on the box or crate.
•The integrity of the tamper-proof tape used to seal the box or crate has not been
compromised.
•The warranty seals on the device itself do not show evidence of tampering.
Before You Begin
•It is recommended that two people be available to mount the PA-4000 Series in a 19-inch rack.
•Have a Phillips head screwdriver available.
•Verify that the intended location has adequate air circulation and meets the temperature
requirements. Refer to “Environmental Specifications” on page 19.
•Allow clear space at the front and back of the device.

Equipment Rack Installation
10 • Installing the Hardware Palo Alto Networks
•Unpack the device.
•Verify that power is not connected to the device.
Equipment Rack Installation
Figure 4 illustrates how rack mounting brackets are attached to the PA-4000 Series. You can attach the
brackets using the holes at the front or the midpoint of the unit.
Figure 4. Attaching Rack Mounting Brackets
The following safety guidelines apply to rack installation:
•Elevated ambient operating temperature—If the PA-4000 Series is installed in a closed or
multi-unit rack assembly, the ambient operating temperature of the rack environment may be
greater than the ambient room temperature. Verify that the ambient temperature of the rack
assembly meets the maximum rated ambient temperature requirements listed in “Environmental
Specifications” on page 19.
•Reduced air flow—Ensure that the airflow required for safe device operation is not compromised
by the rack installation.
•Mechanical loading—Ensure that the rack-mounted device does not cause hazardous conditions
due to uneven mechanical loading.
•Circuit overloading—Ensure that the circuit that supplies power to the device is sufficiently rated
to avoid circuit overloading or excess load on supply wiring. Refer to “Electrical Specifications”
on page 18.
•Reliable earthing—Maintain reliable earthing of rack mounted equipment. Pay special attention
to supply connections other than direct connections to the branch circuit (such as use of power
strips).

Connecting Cables to the Device
To install the PA-4000 Series in a grounded 19-inch rack:
1. Screw the rack mounting brackets onto the front or midpoint of the unit using a Phillips head
screwdriver.
2. Lift the device and position it in the rack. It is recommended that two people perform this function.
3. Align the mounting holes on the side of the device with holes in the rack rail. Make sure that rack
rail holes are selected so that the PA-4000 Series is level.
4. Insert mounting screws into the aligned holes. Tighten with a Phillips screwdriver.
Connecting Cables to the Device
Figure 5 shows the cable connections of the PA-4050 and PA-4020. Refer to Table 1 for descriptions of
the front panel interfaces.

Maintaining the Hardware
This chapter describes how to replace power supplies, interpret LEDs, and troubleshoot hardware
problems. For more information, refer to the following topics:
•“Cautions and Warnings” in the next section
•“Replacing a Power Supply” on page 13
•“Interpreting the Device LEDs” on page 14
•“Interpreting the Port LEDs” on page 15
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.
