Equipment Rack Installation
The
WF-500 appliance
ships with a 4-post rack kit with two sets of rail assemblies (one for each side) and the mounting screws needed for installing the system into a 4-post, 19”rack.
This rail kit will fit a rack between 26.5” and 36.4” deep.
Note:
You can also order a 2-post rail kit from Palo Alto Networks for installation
in a 2-post rack. See “2-post Rack Installation” on page 15 for installation
procedures.
The following safety guidelines apply to rack installation:
•
Elevated ambient operating temperature
—If the WF-500 appliance 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 24.
•
Reduced airflow
—Ensure that the airflow required for safe device operation is not compromised by the rack installation and that you allow at least 30” of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.
•
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. See
“Electrical Specifications” on page 24.
•
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 the use of power strips).
Rack Mount Procedures
The following sections describe the steps needed to install the WF-500 appliance in a 2-post or
4-post 19” rack:

4-post Rack Installation
1.
Unpack the rail kit, which contains two rail assemblies (one for each side of the WF-500 appliance). Each assembly consists of three sections: An inner rail that secures directly to the chassis, an outer rail that secures to the rack, and a middle rail that extends from the outer rail. These assemblies are specifically designed for the left and right side of the chassis.
Note:
Each inner rail has a locking tab, which locks the chassis into place when installed and pushed fully into the rack. These tabs also lock the chassis in place when fully extended from the rack to prevent the chassis from coming completely out when servicing.
2.
Pull the inner rail out of the outer rail until it is fully extended and then press the locking
tab down to release the inner rail as shown in Figure 3. Repeat this step on the other rail.

Install the left inner rail on the left side of the chassis and the right inner rail on the right side of the chassis. The inner rails install over the mounting hooks and then slide forward to lock in place. The mounting screw holes will be exposed at which time you can use the
provided screws to secure the inner rail to the chassis as shown in Figure 4.

4.
Attach the outer rail to the rack by pressing upward on the locking tab at the rear end of the middle rail and then push the middle rail back into the outer rail and then hang the hooks of the front of the outer rail onto the slots on the front of the rack as shown in
Figure 5. If necessary, use screws to secure the outer rails to the rack.

5.
Pull out the rear of the outer rail, adjusting the length until it fits within the posts of the rack.
6.
Hang the hooks of the rear portion of the outer rail onto the slots on the rear of the rack. If necessary, use screws to secure the rear of the outer rail to the rear of the rack as shown in
Figure 5.
7.
Repeat these steps for the remaining rail.
8.
Install the chassis into the rack by pulling the middle rail out from the front of the outer rail, ensuring that the ball-bearing shuttle is at the front locking position of the middle rail.
9.
Align the chassis inner rails with the front of the middle rails and slide the inner rails on the chassis into the middle rails, keeping even pressure on both sides until the locking tab

of the inner rail clicks into the front of the middle rail as shown in Figure 6. This will lock
the chassis into the fully extended position.

10. Depress the locking tabs of both sides at the same time and push the chassis all the way
into the rear of the rack as shown in Figure 6.
11. Use rack mounting screws to secure the chassis to the rack. The mounting holes are located on the front handles of the chassis.

2-post Rack Installation
Note:
The WF-500 appliance ships with a 4-post rack kit. You can order a 2-post rail kit from Palo Alto Networks for installation in a 2-post rack.
1.
Unpack the 2-post rail kit, which contains two rail assemblies (one for each side of the
WF-500 appliance). Each assembly consists of two sections: An inner rail that secures directly to the chassis and an outer rail that attaches to the inner rail and screws into the chassis. The inner rail has mounting holes that mount to the front of the rack post and the outer rail has mounting holes that mount to the back of the rack post.
2.
Separate the inner and outer rails by sliding the outer rail until the posts reach the round
holes and then evenly pull the outer rail away from the inner rail as shown in Figure 7.

3.
Slide the inner rails on each side of the chassis over the chassis hooks. There are six hooks; install the inner rail on the middle four hooks and then secure the inner rails on both sides
of the chassis using the flat-head screws as shown in Figure 8.
Note:
You can install the inner rail to the chassis using only one screw since this only prevents the rail from sliding. The chassis hooks and inner rail provide the majority of strength/stability for the rail.

4.
Using at least two people, mount the chassis to the rack securing the front (inner rail) mount holes to the front of the rack with the rack mount screws and washers as shown in
Figure 8.

5.
The chassis will be able to support itself in the rack at this point, but the rear outer rails are required to fully secure the chassis. Align the outer rail holes with the inner rail post and push the outer rail into place and then slide forward until the rack mount holes rest against the rack post. Secure the rail to the post with the provided rack mount screws and washers.

Install the cylinder head screw through the outer rail to the inner rail threaded post as
shown in Figure 9.
CAUTION:
It is important that you secure the outer rail to the inner rail with the cylinder head screw to ensure that the outer rail does not inadvertently become separated from the inner rail.
