Part 1: Mount the Switch into a 4-Post Rack

CAUTION : A QFX5220 requires two people for installation, one person to lift the device into place and another person to attach the device to the rack. If you are installing the QFX5220 above 60 in. (152.4 cm) from the floor, you can remove the power supplies and fan modules to minimize the weight before attempting to install the device.
CAUTION : If you are mounting multiple devices on a rack, mount the device in the lowest position of the rack first. Proceed to mount the rest of the devices from the bottom to the top of the rack to minimize the risk of the rack toppling.

You can mount QFX5220 switches on a four-post 19-in. rack or cabinet using the rack mount kit provided with the switch. The rack mount kit can be adapted for either a 4-post rack-only or a rack and cabinet installation. A four-post installation is the preferred installation method because the switch is evenly supported by all four corners. Using the two-post mounting method, the switch is two-thirds cantilevered in the rack.

To mount the QFX5220-32CD on a four post rack using the provided rack mount kit:

1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.

2. Decide whether the Field Replaceable Unit (FRU) end of the switch or the port end is to be placed at the front of the rack. Position the device in such a manner that the AIR IN labels on components are next to the cold aisle and AIR OUT labels on components are next to the hot aisle.

3. Align the holes in the mounting rail with the holes on the side of the chassis. See Figure 1 on page 3 to see the proper alignment for the QFX5220-32CD.
   Figure 1: Attaching Mounting Rails to the QFX5220-32CD

4. Attach the mounting rail to the switch using six flathead screws. Tighten the screws using a Phillips # 2 screwdriver.

5. Repeats steps 3 and 4 on the opposite side of the switch.

6. Have one person grasp both sides of the switch, lift it, and position it in the rack so that the front rail is aligned with the rack holes.

7. Have a second person secure the front of the switch to the rack using four mounting screws (and cage nuts and washers if your rack requires them.) Tighten the screws. See Figure 2 on page 4 for an example of connecting the mounting rails and mounting blades to a QFX5220-32CD.
   Figure 2: Attach QFX5220-32CD to Rack

8. Continue to support the switch while sliding the mounting blades into the channel of the mounting rails and securing the blades to the rack. Use the four mounting screws (and cage nuts and washers if your rack requires them) to attach each blade to the rack. Tighten the screws. See Figure 3 on page 4.
   Figure 3: Slide Mounting Blade into Mounting Rail

9. Ensure that the switch chassis is level by verifying that all the screws on the front of the rack are aligned with the screws at the back of the rack.

10. We recommend that you insert dust covers in any unused ports.

Ground the Chassis and Connect Power

To connect earth ground to a QFX5220-32CD:

1. Use two 10-32 x 0.25 screws with #10 split-lock washers to secure the grounding lug and attached cable to the chassis. Attach the lug through the left rail and blade assembly to the chassis. The posts on the grounding lug should point to the left. See Figure 4 on page 5.
   Figure 4: Connecting a Grounding Cable to a QFX5220-32CD

2. Connect the remaining end of the grounding cable to a proper earth ground, such as the rack in which the switch is mounted.

3. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.

Connect Power to the Switch

The QFX5220 is shipped from the factory with two power supplies. Each power supply is a hot-removable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install a replacement power supply in either of the two slots next to the fan modules without powering off the switch or disrupting the switching function.

To connect AC power to a QFX5220:

1. Attach the grounding strap to your bare wrist and to a site ESD point.

2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. .

3. Locate the power cords shipped with the switch; the cords have plugs appropriate for your geographical location. See AC Power Cord with Type C15 Coupler Specifications.
   For each power supply:

4. Ensure the loop on the power cord retainer is open and there is enough space to insert the power cord coupler into the inlet. If the loop is closed, press the small tab on the retainer to loosen the loop.

5. Thread the power cord coupler through the power cord retainer loop.

6. Insert the power cord coupler firmly into the AC inlet on the power supply faceplate.

7. Slide the power cord retainer loop towards the power supply until it is snug against the base of the coupler.

8. Press the tab on the loop and draw out the loop to enclose the power cord. See Figure 5 on page 6.
   Figure 5: Attaching the Power Cord Retainer
   WARNING: Ensure that the power cord does not block access to device components or drape where people can trip on it.

9. If the AC power source outlet has a power switch, set it to the OFF (O) position.
   NOTE : The switch powers on as soon as power is provided to the power supply. There is no power switch on the device.

10. Insert the power cord plug into an AC power source outlet.

11. If the AC power source outlet has a power switch, set it to the ON (|) position.

12. Verify that the AC and DC LEDs on each power supply are lit green.
    If the amber fault LED is lit, remove power from the power supply, and replace the power supply (see How to Remove a Power Supply from a QFX5220). Do not remove the power supply until you have a replacement power supply ready: the power supplies must be installed in the switch to ensure proper airflow.
    CAUTION : Replace a failed power supply with a new power supply within three minutes of removal to prevent chassis overheating.

Connect the QFX5220-32CD to the Network and Perform the Initial Configuration
