Install the EX4100 Switch

SUMMARY This topic guides you through the steps to install EX4100 switches.

Unpack the EX4100 Switch

Juniper Networks ships EX4100 switches in a cardboard carton, secured with foam packing material. The carton has an accessory compartment.

CAUTION:

The shipping carton completely protects EX4100 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 EX4100 Switch).
  6. Save the shipping carton and packing materials in case you need to move or ship the switch later.

Packing List for an EX4100 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 EX4100 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. For international-dial or direct-dial options in countries without toll-free numbers, see https://www.juniper.net/support/requesting-support.html.
