Unpacking and Mounting the QFX5200

 

Unpacking a QFX5200

The QFX5200 switch chassis is a rigid sheet-metal structure that houses the hardware components. A QFX5200 is shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box and quick start instructions.

Caution

The QFX5200 is maximally protected inside the shipping carton. Do not unpack the switch until you are ready to begin installation.

To unpack a QFX5200:

  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. Remove the accessory box and verify the contents against the inventory included in the box. Table 1 lists the inventory of components supplied with a QFX5200.
  5. Pull out the packing material holding the switch in place.
  6. Verify the chassis components received:
    • Two power supplies

    • Five fan modules for QFX5200-32C or QFX5200-32C-L and six fan modules for QFX5200-48Y

  7. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Mounting a QFX5200 in a Rack or Cabinet

You can mount all QFX5200 switches on a four post 19-in. rack or cabinet using the mounting kit provided with the switch.

For four post rack or cabinet installations, the mounting kit contains two front mounting rails with two matching rear mounting blades. 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 remainder of this topic uses “rack” to mean “rack or cabinet.”) The front and rear rack rails must be spaced between 23.5 in. (59.7 cm) and 30.6 in. (77.7 cm) front to back.

This topic describes:

Before You Begin Rack Installation

Before you begin mounting a QFX5200 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 QFX5200 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 General Site Guidelines, with particular attention to QFX5200 Installation Safety Guidelines.
  5. Remove the switch from the shipping carton (see Unpacking a QFX5200).
  6. Ensure that you have the following parts and tools available to mount the switch in a rack:
    • ESD grounding strap (not provided).

    • Blades, rails, or brackets (provided).

      • For four-post installations:

        • One pair of rear mounting blades. These mounting blades support the rear of the chassis and must be installed (provided).

        • One pair of front mounting rails. The mounting blades slide into the mounting rails to support the switch (provided).

        • Screws to secure the mounting rails to the chassis (provided).

          • Twelve screws for QFX5200-32C or QFX5200-32C-L

          • Twenty screws for QFX5200-48Y

        • Eight screws to secure the chassis and rear installation blades to the rack (not provided).

    • Appropriate screwdriver for the mounting screws (not provided).

    • Two power cords with plugs appropriate to your geographical location (provided).

    • RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided).

    • Management host, such as a PC laptop, with a serial port (not provided).

Optional equipment: Grounding cable kit with bracket, lug, and three nuts with integrated washers.

Warning

A QFX5200 switch must be supported at all four corners. Mounting the chassis using only the front brackets will damage the chassis and can result in serious bodily injury.

Caution

All QFX5200 switches require two people for installation, one person to lift the switch into place and another person to attach the switch to the rack. If you are installing the QFX5200 switch 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 switch.

Caution

If you are mounting multiple switches on a rack, mount the switch in the lowest position of the rack first. Proceed to mount the rest of the switches from the bottom to the top of the rack to minimize the risk of the rack toppling.

Four Post Installation Procedure for QFX5200-32C or QFX5200-32C-L

To mount the QFX5200-32C or QFX5200-32C-L on four posts in a rack using the provided mounting 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 switch 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 to see the proper alignment for the QFX5200-32C or QFX5200-32C-L switch.
