Page 11: About The Documentation
Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshooting for the EX4550 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 43: Expansion Modules In Ex4550 Switches
Configuring the LCD Panel on EX Series Switches (CLI Procedure) | 175 Expansion Modules in EX4550 Switches EX4550 switches support three optional expansion modules—an 8-port 10-Gigabit SFP+ expansion module, an 8-port 10GBASE-T expansion module, and a 2-port 40-Gigabit QSFP+ expansion module. Expansion modules are hot-insertable and hot-removable field replaceable units (FRUs).
Page 44 You must order them separately. You can install up to two expansion modules in an EX4550 switch—one in each of the module slots on the front panel and the rear panel of the switch. By installing an expansion module, you add more ports to your switch, thereby increasing the port density of the switch.
Page 45 Each expansion module has an LED on the faceplate (labeled ST). It indicates the status of the expansion module. Figure 11 on page 45 shows the location of LEDs on the SFP+ expansion module.

Page 91: Signal Loss In Multimode And Single-Mode Fiber-Optic Cable
To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. EX Series switches use various types of network cable, including multimode and single-mode fiber-optic cable. Signal Loss in Multimode and Single-Mode Fiber-Optic Cable Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).
Page 92: Calculating The Fiber-Optic Cable Power Budget For Ex Series Devices
An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications.

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 149 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.
