Page 28: Expansion Modules For The Ex4600
Expansion Modules for the EX4600 The EX4600 switch has two bays on the port panel in which you can optionally install one or two expansion modules. The EX4600 supports the same two expansion modules as the QFX5100, which increase port density: EX4600-EM-8F, which provides 8 additional 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) ports.
Page 29: Ex4600-Em-8F
Chapter 1: Overview QFX-EM-4Q, which provides 4 additional 40-Gigabit Quad SFP+ (QSFP+) ports. The EX4600 is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down.
Page 30: Qfx-Em-4Q
QFX-EM-4Q The QFX-EM-4Q, provides 4 additional 40-Gigabit Ethernet QSFP+ ports to one of the bays in the EX4600 switch. Port 0 and port 2 can be used for port channelization by configuring the system mode for 104 port mode. Figure 11 on page 30 shows the QFX-EM-4Q ports and LEDs.

(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 98 Remove the rubber safety cap when you are ready to connect the cable to the transceiver. WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes. Copyright © 2019, Juniper Networks, Inc.

If the fiber-optic cable connector is covered with a rubber safety cap, remove the cap. Save the cap. Remove the rubber safety cap from the optical transceiver. Save the cap. Insert the cable connector into the optical transceiver (see Figure 45 on page 100). Copyright © 2019, Juniper Networks, Inc.
Page 100: Disconnecting A Fiber-Optic Cable
Disconnecting a Fiber-Optic Cable Juniper Networks devices have field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables. Before you begin to disconnect a fiber-optic cable from an optical transceiver, ensure that you have taken the necessary precautions for safe handling of lasers.
Page 101: Maintaining Fiber-Optic Cables
Cover the fiber-optic cable connector with the rubber safety cap. Maintaining Fiber-Optic Cables Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices. To maintain fiber-optic cables: When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver and on the end of the cable.

This topic applies only to the J-Web Application package. Alarms alert you to conditions that might prevent normal operation of the switch. Before monitoring alarms on a Juniper Networks EX Series Ethernet switch, become familiar with the terms defined in Table 33 on page 107.
Page 108: Interface Alarm Messages
Fibre Channel alarms are only valid on QFX3500 devices. NOTE: When red alarms or major alarms are issued on QFX5100 and EX4600 switches, the alarm LED glows amber instead of red. By default, major alarms are configured for interface link-down conditions on the control plane and management network interfaces in a QFabric system.
