The transceivers for Juniper Networks devices 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.
Before you begin removing a transceiver from a device, ensure that you have taken the necessary precautions for the safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Ensure that you have the following parts and tools available:
An antistatic bag or an antistatic mat
Rubber safety caps to cover the transceiver and fiber-optic cable connector
A dust cover to cover the port or a replacement transceiver
Figure 1 shows how to remove a QSFP+ transceiver . The task is the same for all types of transceivers except the QSFP28 and CFP transceivers.
To remove a transceiver from a device:
1.Place the antistatic bag or antistatic mat on a flat, stable surface.
2.Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
3.Label the cable connected to the transceiver so that you can reconnect it correctly.
4.Remove the cable linked to the transceiver (see Disconnecting a Fiber-Optic Cable). Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety cap immediately after disconnecting the fiber-optic cables.
5.To eliminate an SFP, SFP+ , XFP, or a QSFP+ transceiver:
a.By using your fingers, pull open the ejector lever on the transceiver to unlock the transceiver.
b.Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port.
To remove a CFP transceiver:
a.Loosen the screws on the transceiver by using your fingers.
b.Grasp the screws on the transceiver and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight from the port.
6.By using your fingers, grasp the body of the transceiver and pull it straight out of the port.
7.Place the transceiver in the antistatic bag or on the antistatic mat placed on a set, stable surface.
8.Place the dust cover over the empty port or install the replacement transceiver.
Installing a Transceiver
The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can replace them without powering off these devices or disrupting the device functions.
Before you start to install a transceiver in a device, make sure that you took the required precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Make sure that you possess a rubber safety cap available to cover the transceiver.
1.Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
2.Take away the transceiver from its bag.
3.Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.
4.If the port in which you need to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you should cover the port later. If you are hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver from the port before installing a new transceiver.
5.Using both hands, carefully place the transceiver in the empty port. The connectors must face the chassis.
6.Slide the transceiver in gently until it is fully seated. If you are installing a CFP transceiver , tighten the captive screws on the transceiver through the use of your fingers.
7.Remove the rubber safety cap when you are ready to connect the cable to the transceiver.
