Unpacking and Mounting the QFX5110

Unpacking a QFX5110

The QFX5110 is a rigid sheet-metal structure that houses the hardware components. A QFX5110 is shipped in a cardboard carton, secured with foam packing material. The carton also contains an accessory box and a Documentation Roadmap card.

CAUTION:

The QFX5110 is maximally protected inside the shipping carton. Do not unpack the switch until you are ready to begin installation.

To unpack a QFX5110:

  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 QFX5110.
  5. Pull out the packing material holding the switch in place.
  6. Verify the chassis components received:

    • Two power supplies

    • Five fan modules

    The QFX5110-32Q-CHAS is shipped without power supplies or fan modules.

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

Note:

We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

Register Products—Mandatory to Validate SLAs

Register all new Juniper Networks hardware products and changes to an existing installed product using the Juniper Networks website to activate your hardware replacement service-level agreements (SLAs).

CAUTION:

Register product serial numbers on the Juniper Networks website. Update the installation base data if any addition or change to the installation base occurs or if the installation base is moved. Juniper Networks is not responsible for not meeting the hardware replacement service-level agreement for products that do not have registered serial numbers or accurate installation base data.

Mounting a QFX5110 in a Rack

You can mount a QFX5110 on a four-post 19-in. rack using the mounting kit provided with the switch.

Space the front and rear rack rails between 23.5 in. (59.7 cm) to 30.6 in. (77.7 cm) front-to-back.

Before You Begin Rack Installation

Before you begin mounting a QFX5110 switch in the rack:

  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 QFX5110 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, and the QFX5110 Installation Safety Guidelines.
  5. Remove the switch from the shipping carton.
  6. Ensure that you have the following parts and tools available to mount the switch in a rack:

    • ESD grounding strap (not provided).

    • Rack Mount Kit (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 (not provided).

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

    Note:

    We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

Optional equipment: grounding cable kit with bracket, lug, and two screws and washers.

CAUTION:

All QFX5110 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 QFX5110 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.

Mount a QFX5110 in a Rack or Cabinet by Using the JNP-4PST-RMK-1U-E Rack Mount Kit

You can mount the QFX5110 switches on a square hole or threaded hole four-post 19-in. racks using the partial tool less JNP-4PST-RMK-1U-E rack mount kit which is available as a spare.

JNP-4PST-RMK-1U-E rack mount kit consists of the following parts:

  • A pair of front and rear mounting rails

  • A pair of mounting brackets

  • 16 flat head M4 x 6mm Phillips screws

A four-post installation evenly supports the device by all four corners.
