QFX5700 Transceiver and Fiber Optic Cable Installation and Removal
The transceivers for the QFX5700 switch are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.
To understand how to install or remove a transceiver of a QFX5700 switch, read the following sections.
QFX5700 Transceiver Installation
Before you begin to install a transceiver in a QFX5700 line card, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Ensure that you have a rubber safety cap available to cover the transceiver.
To install a transceiver in the QFX5700 line card or the RCB:
To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.
QFX5700 Transceiver Removal
Before you begin to remove a transceiver from the QFX5700 line card or RCB, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Ensure that you have the following parts and tools available:
Antistatic bag or an antistatic mat
Rubber safety caps to cover the transceiver and fiber-optic cable connector
Dust cover to cover the port

How to Connect a Fiber-Optic Cable from a Transceiver on a QFX5700 Switch
Before you connect a fiber-optic cable to an optical transceiver installed in the QFX5700 switch, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
To connect a fiber-optic cable to an optical transceiver installed in the QFX5700 switch:
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.
Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.
How to Disconnect a Fiber-Optic Cable from a Transceiver on a QFX5700 Switch
Before you disconnect a fiber-optic cable from an optical transceiver installed in the QFX5700 switch, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Ensure that you have the following parts and tools available:
Rubber safety cap to cover the transceiver
Rubber safety cap to cover the fiber-optic cable connector
To disconnect a fiber-optic cable from an optical transceiver installed in the QFX5700 switch:
Fiber-Optic Cable Maintenance for a QFX5700 Switch
To maintain fiber-optic cables in the QFX5700 switch:
When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver and on the end of the cable.
Anchor the fiber-optic cable to avoid stress on the connectors. When you attach a fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it is not supporting its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.
Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments.
Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.
To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions in the cleaning kit you use.
After you clean the transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such as the Cletop-S® Fiber Cleaner. Follow the directions in the cleaning kit you use.
