Install the EX4100-H Switch

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

Unpack the EX4100-H Switch

We ship the EX4100-H switches in a cardboard carton, secured with foam packing material. The carton has an accessory compartment.

CAUTION:

The shipping carton completely protects the EX4100-H 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-H 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-H 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-H 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.

CAUTION:

For all mounting options:

  1. The EX4100-H switch (with PSU if using external PSU) must be installed in cabinet or enclosure to prevent any personal injury due to access to live parts. The enclosure shall be accessible by using a tool. The access to the switch shall be restricted. Only instructed and skilled person must access the switch.

  2. The cabinet or enclosure must meet the fire enclosure requirements of UL, EN 62368-1 to ensure no foreign objects fall into the switch (and PSU if using external PSU) and no flaming particles fall out from the switch (and PSU if using external PSU) to outside.

  3. User shall assess the climatic/environmental conditions at installation site to select the cabinet/enclosure to ensure that the switch (and PSU if using external PSU) is protected from dust, rain, salt fog, pollutants to prevent any damage. Below are few examples.

    • For indoor and indoor non office installation with very low dust/moisture – cabinet/enclosure must be certified to minimum IP 54 (defined in EN60529) or TYPE 4 (defined in UL 50).

    • For installing the switch (and PSU if using external PSU) in outdoor environment (to protect from dust, corrosion, moisture, salt fog, pollutants, rain) enclosure or cabinet must be certified to IP65 or higher (IP code defined in EN 60529) or TYPE 4 (defined in UL 50E, UL50)

Update Base Installation Data

CAUTION:

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 SLA for products that do not have accurate installation base data.

Mount an EX4100-H-12MP Switch on a Ferrous Wall or Surface Using Magnet Pads Within a Cabinet

Before mounting the switch on a wall. ensure that you have the following parts and tools available:

  • Two magnet support plates(one for the switch and the other for the PSU)

  • Eight M5 L8 screws

  • Two magnet pads

Note:

Magnet mounting is to be done within the building only, not to be installed outside of building. Switch and PSU has to be mounted in a location where there is no direct sunlight on the switch and PSU. Switch and PSU should not be installed near to heat source as the temperature affects magnet performance.

CAUTION:

If you do not install the magnet and the device correctly, it could lead to a hazard. Use only the magnet kit provided by Juniper to mount your device. You can mount the switches on a ferrous wall in IT or secure room using magnet pads.
Note:

  • You can mount the units on a ferrous wall using magnet pads, at a height of no more than 2 m.

  • Make sure the ferrous wall is smooth and free of any contaminants like oil, grease, dirt, etc., as otherwise the unit may fall.

  • Ensure that the ferrous wall on which the switch is mounted isn’t close to any area where any vibration or impact may occur. Also, you must not mount the product near any heat-generating area as it can cause the mounting to malfunction.

  • Allow a sufficient space of 2 in. 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.
