Removing a Transceiver from a J-EX Series Switch
The transceivers for J-EX Series switches are hot-removable and hot-insertable
field-replaceable units (FRUs): You can remove and replace them without powering off
the switch or disrupting switch functions.
Before you begin removing a transceiver from a J-EX Series switch, ensure that you have
taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety
Guidelines and Warnings for J-EX Series Switches” on page 165).
Ensure that you have the following parts and tools available:
•
An antistatic bag or an antistatic mat
• Needlenose pliers
• Rubber safety caps to cover the transceiver and fiber-optic cable connector
•
A dust cover to cover the port
Figure 59 on page 138 shows how to remove an SFP transceiver. The procedure is the
same for all transceiver types.
To remove a transceiver from a J-EX Series switch:
1.
Place the antistatic bag or antistatic mat on a flat, stable surface.
2.
Label the cable connected to the transceiver so that you can reconnect it correctly.
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.
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. An arc smaller than a few inches in diameter can damage the cables
and cause problems that are difficult to diagnose.
3.
Remove the cable connected to the transceiver (see “Disconnecting a Fiber-Optic
Cable from a J-EX Series Switch” on page 136). Cover the transceiver and the end of
each fiber-optic cable connector with a rubber safety cap immediately after
disconnecting the fiber-optic cables.
4.
Using your fingers, pull the ejector lever on the transceiver to unlock the transceiver.
