Unpacking and Mounting the QFX5220

 

Unpacking a QFX5220

The QFX5220 chassis is a rigid sheet-metal structure that houses the hardware components. A QFX5220 is shipped in a cardboard carton, secured with foam packing material.

Caution

The QFX5220 is maximally protected inside the shipping carton. Do not unpack the switch until you are ready to begin installation.

To unpack a QFX5220:

  1. Move the shipping carton to a staging area as close to the installation site as possible, but where you have enough room to remove the system components.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Pull out the packing material holding the switch in place.
  5. Verify the contents against the inventory included in the box. Table 1 lists the inventory of components supplied with a QFX5220-32CD and Table 2 lists the inventory of components supplied with a QFX5220-128C.
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Mounting a QFX5220 in a Rack or Cabinet

You can mount QFX5220 switches only 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 four-post rack-only or a rack and cabinet installation. A four-post installation evenly supports the switch by all four corners.

For four-post rack or cabinet installations, the mounting kit contains two front mounting rail assemblies and two rear mounting blades that match the front mounting rails. This configuration allows either end of the switch to be mounted flush with the rack and still be adjustable for racks with different depths.

The front and rear rack rails must be spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm) front to back.

Before You Begin Rack Installation

Before you begin mounting a QFX5220 switch in the rack or cabinet:

  1. Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
  2. Verify that the site meets the requirements described in QFX5220 Site Preparation Checklist.
  3. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
  4. Read Chassis and Component Lifting Guidelines.
  5. Remove the switch from the shipping carton (see Unpacking a QFX5220 ).
  6. In addition to the items in Table 1 and Table 2, ensure that you have the following parts and tools available that are not normally provided with the device to mount the switch in a rack:
    • ESD grounding strap

    • Appropriate screwdriver for the mounting screws

    • Screws to attach the device to the rack

    • Management host, such as a PC laptop, with a serial port

    • Grounding lug, grounding wire, screws and washers

    • Dust covers for unused ports

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.
