Juniper QFX5240 - Connect a Fiber-Optic Cable

1. Disable the port in which the transceiver is installed by issuing the following command:
[edit interfaces]
user@device# set interface-name disable
LASER WARNING: Do not look directly into a ber-opc transceiver or into the ends
of ber-opc cables. Fiber-opc transceivers and ber-opc cables connected to
transceivers emit laser light that can damage your eyes.
2. Carefully unplug the ber-opc cable connector from the transceiver.
3. Cover the transceiver with a rubber safety cap.
LASER WARNING: Do not leave a ber-opc transceiver uncovered except when
inserng or removing a cable. The rubber safety cap keeps the port clean and protects
your eyes from accidental exposure to laser light.
4. Cover the ber-opc cable connector with the rubber safety cap.
Connect a Fiber-Opc Cable
Before you connect a ber-opc cable to an opcal transceiver installed in a device, ensure that you
have taken the necessary precauons for safe handling of lasers (see Laser and LED Safety Guidelines
and Warnings ).
To connect a ber-opc cable to an opcal transceiver installed in a device:
LASER WARNING: Do not look directly into a ber-opc transceiver or into the ends of
ber-opc cables. Fiber-opc transceivers and ber-opc cables connected to
transceivers emit laser light that can damage your eyes.
1. If the ber-opc cable connector is covered with a rubber safety cap, remove the cap. Save the cap.
2. Remove the rubber safety cap from the opcal transceiver. Save the cap.
3. Insert the cable connector into the opcal transceiver (see Figure 42 on page 108).
