Maintaining Transceivers on the NFX250

Installing a Transceiver in an NFX250 Device

Before you begin installing a transceiver in an NFX250 device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the NFX250 Devices).

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

The transceivers for the NFX250 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.

To install a transceiver in a NFX250 device:

CAUTION:

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

Remove the transceiver from its bag.
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.
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.
Using both hands, carefully place the transceiver in the empty port. The connectors must face the device chassis.
CAUTION:
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. See Figure 1 for the correct orientation for your device.
Slide the transceiver in gently until it is fully seated. See Figure 1 for an example of inserting an SFP or SFP+ transceiver.
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.

Removing a Transceiver from an NFX250 Device

Before you begin removing a transceiver from the NFX250 device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the NFX250 Devices).

Ensure that you have the following parts and tools available:

Electrostatic bag or an antistatic mat
Rubber safety caps to cover the transceiver and fiber-optic cable connector
Dust cover to cover the port

To remove a transceiver from the NFX250 device:

Place the antistatic bag or antistatic mat on a flat, stable surface.
Label the cable connected to the transceiver so that you can reconnect it correctly.
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.

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.

CAUTION:
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.
Remove the cable connected to the transceiver (see Disconnecting a Fiber-Optic Cable from an NFX250 Device). Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety cap immediately after disconnecting the fiber-optic cables.
Using your fingers, pull the ejector lever away from the transceiver to unlock the transceiver.
CAUTION:
Before removing the transceiver, make sure you open the ejector lever completely until you hear it click. This prevents damage to the transceiver.
Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port (see Figure 2).
CAUTION:
To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.
Using your fingers, grasp the body of the transceiver and pull it straight out of the port.
Place the transceiver in the electrostatic bag or on the antistatic mat placed on a flat, stable surface.
Place the dust cover over the empty port.
