Install the EX4000 Switch

This topic guides you through the steps to install EX4000 switches.

Unpack the EX4000 Switch

Juniper Networks ships EX4000 switches in a cardboard carton, secured with foam packing material. The carton has an accessory compartment.

CAUTION:

The shipping carton completely protects EX4000 switches. Leave the switches safely in the carton until you are ready to begin installation.

To unpack the switch:

  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 parts received against the inventory on the label attached to the carton (see Packing List for an EX4000 Switch).
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Packing List for an EX4000 Switch

The switch shipment includes a packing list. Check the parts you receive with the switch against the items on the packing list. The packing list specifies the part number and provides a description of each part in your order. The parts shipped match the switch model you ordered (see EX4000 Models and Specifications).

If any part on the packing list is missing, contact your customer service representative or contact Juniper customer care from within the U.S. or Canada by telephone at 1-888-314-5822.

  • The ferrous wall on which the switch is mounted shall not be close to any area where vibration or impact may occur. The product shall not be mounted in a place where direct sunlight occurs. Also, mounting the product near any heat generating area can cause the mounting to malfunction.

  • Allow sufficient space of 6 inches all around the switch for cooling. Insufficient space can lead to overheating of the switch chassis.

  • The ferrous wall on which the switch will be mounted shall be flat and the surface shall be without any undulation. The ferrous wall shall be well supported and strong enough to support the switch.

To mount the switch on a surface made of ferrous material:

  1. Turn the chassis upside down.
  2. Use the Phillips (+) screwdriver (number 2) to assemble the magnet tray on the bottom side of the switch by using four M4 screws.
