Installing a Transceiver in a QFX Series Device

Before you begin installing a transceiver in a QFX Series device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the QFX Series).

Ensure that you have a rubber safety cap available to cover the transceiver.

The transceivers for the QFX Series 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 install a transceiver in the QFX Series:


To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

  1. Remove the transceiver from its bag.
  2. Check to see whether the transceiver is covered by a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.
    Laser 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.

  3. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later.
  4. Using both hands, carefully place the transceiver in the empty port. The connectors must face the device chassis.

    Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. Note that on QFX5100-48T devices, the QSFP+ top and bottom ports have the same orientation for inserting and removing transceivers. On all other QFX Series devices, the ports are designed belly-to-belly, which requires you to turn the transceiver over on the bottom port row. See Figure 1 through Figure 4 for the correct orientation for your device.

  5. Slide the transceiver in gently until it is fully seated. See Figure 1 for an example of inserting an SFP transceiver. Figure 2, Figure 3, and Figure 4 are examples of inserting QSFP+ transceivers into different QFX Series product SKU devices.
  6. Remove the rubber safety cap when you are ready to connect the cable to the transceiver.
    Laser 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.
