Page 12: About The Documentation
Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshooting for the EX4500 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 13: Merging A Full Example
xiii 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 14: Merging A Snippet
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.

Grounded Equipment Warning | 289 Connecting AC Power to an EX4500 Switch The AC power supply in an EX4500 switch is a hot-removable and hot-insertable field-replaceable unit (FRU). After you have installed at least one power supply, you can connect power to the switch.
Page 129 305. Install power supplies in the switch. See “Installing an AC Power Supply in an EX4500 Switch” on page 201. Ensure that you have the following parts and tools available to connect power to the switch: Electrostatic discharge (ESD) grounding strap Power cords appropriate for your geographical location.
Page 130 2. Ensure that the power supply is fully inserted in the chassis. See “Installing an AC Power Supply in an EX4500 Switch” on page 201. 3. Squeeze the two sides of the power cord retainer clip, and insert the L-shaped ends of the clip into the holes in the bracket on each side of the AC appliance inlet.

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 137 3. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap. 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.

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.
Page 139 To connect a fiber-optic cable to an optical transceiver installed in a device: WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables.

Prevention of Electrostatic Discharge Damage Device components that are shipped in antistatic bags are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets.
Page 306: Ac Power Electrical Safety Guidelines
Figure 79: Placing a Component into an Antistatic Bag CAUTION ELECTROSTATIC SENSITIVE DEVICES DO NOT OPEN OR HANDLE EXCEPT AT A STATIC-FREE WORKSTATION CAUTION: ANSI/TIA/EIA-568 cables such as Category 5e and Category 6 can get electrostatically charged. To dissipate this charge, always ground the cables to a suitable and safe earth ground before connecting them to the system.
