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.
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:
- 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.
- Position the carton so that the arrows are pointing up.
- Open the top flaps on the shipping carton.
- Pull out the packing material holding the switch in place.
- Verify the parts received against the inventory on the label attached to the carton (see Packing List for an EX4100-H Switch).
- 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.

Mount an EX4100-H-12MP Switch Using Rack Mount Kit (with DIN Rail) Within a Cabinet
- The EX4100-H-12MP with an AC PSU or DC PSU must be installed in an IP 54 or a NEMA 4 enclosure for all outdoor/non-office installation. The switch must be installed in a cabinet or an enclosure regardless of the switch being installed outdoors or indoors.
- The switch and the PSU must be installed in a suitable enclosure to prevent any personal injury due to access to live parts. The enclosure must be accessible by using a tool. The EX4100-H-12MP must have restricted access only.
- Only skilled persons must be allowed to connect or do the wiring of AC PSU to AC mains.
- In all mounting options, the cables must be routed and held in position with suitable cable organizer or holder, so that the cables do not hang from the switch or the PSU which can accidentally pull down the unit.
When the switch is installed in a cabinet, the temperature within the cabinet is greater than the room temperature outside the cabinet. Ensure the temperature inside the cabinet and around the switch conforms to device specification detailed in Table 2.
For railways and power substation installations, use off-the-shelf (OTS) DIN metal stoppers adjacent to the switch and the PSU.
Footpads are preassembled onto the bottom of the switch and the PSU. If you do not require the footpads, you can unassemble them.
Before mounting the switch using rack mount kit (with DIN Rail) within a cabinet:
-
Verify that the site meets the requirements described in Environmental Requirements and Specifications for EX4100-H Switches.
-
Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the building structure.
-
Read General Safety Guidelines and Warnings, with particular attention to Chassis and Component Lifting Guidelines.
Ensure that you have the following parts and tools available:
-
Rack mounting bracket with DIN rail channel (EX4100-H-12-RM-DRK)
-

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.
-
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.
