Chapter 2 
Installing the Hardware
This chapter describes how to install the PA-2000 Series. 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 11
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-2000 Series in a 19-inch
rack.
•Have a Phillips head screwdriver available.
Note: The PA-2050 and PA-2020 firewalls are collectively referred to as
the PA-2000 Series.

Equipment Rack Installation
10 • Installing the Hardware Palo Alto Networks
•Verify that the intended location has adequate air circulation and meets the temperature
requirements. Refer “Environmental Specifications” on page 18.
•Unpack the device.
•Verify that power is not connected to the firewall.
•Allow clear space on both sides of the firewall.
Equipment Rack Installation
Figure 3 shows how rack mounting brackets are attached to the PA-2000 Series. You can attach
the brackets using the holes at the front of the unit.
Figure 3. Attaching Rack Mounting Brackets
The following safety guidelines apply to rack installation:
•Elevated ambient operating temperature—If the PA-2000 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 18.
•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-2000 Series in a grounded 19-inch rack:
1. Screw the rack mounting brackets onto the front of the unit using a Phillips head
screwdriver.
2. Lift the device and position it in the rack.
3. Align the mounting holes on the attached rack mounting brackets with holes in the rack
rail. Make sure that rack rail holes are selected so that the PA-2000 Series is level.
4. Insert mounting screws into the aligned holes. Tighten with a Phillips screwdriver.
Connecting Cables to the Device
Figure 4 shows the PA-2000 Series cable connections. Refer to Table 1 for descriptions of the
front panel interfaces.
Figure 4. Cable Connections for the PA-2000 Series
Connecting Power
To power the PA-2000 Series, attach a power cable to the device (Figure 2) and plug it into a
grounded wall outlet. Flip the switch to power the device.
CAUTION: Fiber Transceivers that are installed by the user shall be Class I and CDRH
certified.

Maintaining the Hardware
This chapter describes how to replace the hard drive, interpret LEDs, and troubleshoot
hardware problems. For more information, refer to the following topics:
•“Cautions and Warnings” in the next section
•“Replacing a Hard Drive” on page 14
•“Interpreting the Port LEDs” on page 15
Cautions and Warnings
CAUTION: Disconnect all power cords before servicing the PA-2000 Series.
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 and/or rear disk drive cover is to be done only by
trained service person(s). Screws on the rear disk drive cover shall be securely tightened so that a tool is
required for removal.
Note: The PA-2050 and PA-2020 firewalls are collectively referred to as
the PA-2000 Series.

Replacing a Hard Drive
14 • Maintaining the Hardware Palo Alto Networks
Replacing a Hard Drive
To remove the hard drive tray:
1. Make sure the firewall has been powered down.
2. Unscrew the hard disk drive tray thumbnail screws on the back of the firewall (Figure 5).
3. Slide the tray out from the chassis.
4. Detach the power and data cables from the hard disk drive.
Figure 5. Hard Disk Drive Replacement
To insert a hard disk drive tray:
1. Power down the firewall.
2. Partially slide the tray into the chassis.
3. Attach the power and data cables to the hard disk drive.
4. Slide the tray fully into the chassis and tighten the thumbnail screws.
Note: Tighten the thumbnail screws more with a tool after initial and subsequent
access to the hard drive tray.
