Page 11: About The Documentation
Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshooting for the EX4200 switch. After completing the installation and basic configuration procedures covered in this guide, refer to the Junos OS documentation for information about further software configuration.
Page 12: Merging A Full Example
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command. If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command.
Page 13: Merging A Snippet
xiii Merging a Snippet To merge a snippet, follow these steps: 1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform. For example, copy the following snippet to a file and name the file ex-script-snippet.conf.

Page 45: Ex4200 Cooling System
IN THIS SECTION Fan Tray | 46 Airflow Direction in the EX4200 Switch Chassis | 46 The cooling system in an EX4200 switch consists of a field-replaceable unit (FRU) fan tray with three fans (see Figure 15 on page 46). All the EX4200 switch models, except the EX4200-24F-S and EX4200-48T-S switches are shipped with one fan tray pre-installed in the rear panel of the switches.
Page 46: Fan Tray
Fan Tray The fan tray is located at the rear of the chassis. Figure 15: Fan Tray Used in an EX4200 Switch Airflow Direction in the EX4200 Switch Chassis The fan tray located at the rear of the chassis provides side-to-rear chassis cooling (see Figure 16 on page 46).
Page 47: Ex4200 Power System
The fan tray used in an EX4200 switch comes with load-sharing redundancy that can tolerate a single fan failure at room temperature (below 45° C/113° F) to still provide sufficient cooling. Temperature sensors in the chassis monitor the temperature within the chassis. The system raises an alarm if the fan fails or if the temperature inside the chassis rises above permitted levels.
Page 48: Ac Power Supplies
This topic uses the term PoE to refer to both PoE and PoE+ unless there is a need to distinguish between the two. EX4200 switches use power supplies that provides two DC output voltages: 12 V for system and logic power and 48–51 V (or higher, to compensate for voltage drops along the path from the power supplies to the RJ-45 connector) for PoE ports.
Page 49: Dc Power Supplies
All the EX4200 switches that are powered by DC power supplies except the EX4200-24F-S and EX4200-48T-S switches are shipped with one DC power supply pre-installed in the rear panel of the switches. EX4200-24F-S and EX4200-48T-S switches are not shipped with pre-installed power supplies;...

Page 144 Juniper Networks with your Juniper Networks device. CAUTION: If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.
Page 145 WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light. 4. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later.
Page 146: Connect A Fiber-Optic Cable
CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point. CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
