Install the EX4100-H-12T Switch

This topic guides you through the steps to install the EX4100-H-12T switch on walls, desks, two-post racks, four-post racks, and in cabinets.

CAUTION:

For all mounting options:

  • For installing the switch in outdoor environment (to protect from dust, corrosion, moisture, salt fog, pollutants, rain), a sealed enclosure certified to IP 65 or equivalent must be used.

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.

Before mounting the switch in a rack:

Ensure that you have the following parts and tools available:

  • One rack mounting bracket

  • Eight M5 L8 screws

  • An EX4100-H-12-RMK kit

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

You use the EX4100-H-12P-MMK1 mounting kit. 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.
  1. Attach the magnet tray onto the rear of the switch.
    Note: Recommended torque for mounting bracket to the switch and PSU：22 +/- 0.5 Lb.in

Mount an EX4100-H-12T Switch on a Desk or on a Flat Surface Within a Cabinet

You can mount the switch on a desk or any other level surface within a cabinet. The surface or the area must not be an inclined.

Note:

Allow a sufficient space of 2 in. all around the switch for cooling. Insufficient space can lead to overheating of the switch chassis.
Place the switch on a flat surface or a desk within a cabinet and connect to power. See Connect the EX4100-H-12T Switch to Power.

Mount an EX4100-H-12T Switch Using DIN Rail Mount Kit Within a Cabinet

You use the EX4100-H-12P-DRK1 mounting kit. Ensure that you have the following parts and tools available:

  • DIN mounting bracket for the switch

  • Four M5 L8 screws

Note:

  • The product can be mounted onto a standard 35 mm DIN Rail

  • Allow a sufficient space of 2 in all around the switch for cooling. Insufficient space can lead to overheating of the switch chassis.

Mount an EX4100-H-12T Switch on a Wall Within a Cabinet

Before mounting the switch on a wall:

You use the EX4100-H-12P-WMK1 mounting kit. Ensure that you have the following parts and tools available:

  • Wall-mounting bracket (provided in the wall-mounting kit)

  • Wall-mounting bracket screws (provided in the wall-mounting kit)

  • Mounting screws to attach the switch using M5 x 8 mm (provided in the wall-mounting kit)

  • Hollow wall anchors (provided in the wall-mounting kit)

  • A number 2 Phillips (+) screwdriver (not provided)

You can mount an EX4100-H-12T switch on a wall by using the separately orderable wall-mounting kit.

To mount the switch on a wall within a cabinet:

  1. Attach the wall-mounting bracket to the switch.
    Note: Recommended torque for mounting bracket to the switch and PSU：22 +/- 0.5 Lb.in
    Figure 18: Attach wall-mounting bracket to the switch Assembly diagram showing how to mount a device onto a bracket or wall mount. Labels include AGENCY LABEL and SYS INFO LABEL. Screws with dashed lines indicate placement. Green arrow shows bracket attachment direction.
  2. Drill holes as per the measurements in the following figure to install the mounting screws for the wall-mounting brackets of the switch. If the mounting screws are inserted in a wall board with no stud behind it, you must use dry wall anchors rated to support 75 lb (34 kg). Insert the screws into wall studs wherever possible to provide added support for the switch chassis.Tighten the screws only partway in, leaving about 1/4 in. (6 mm) distance between the head of the screw and the wall.
