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 207).
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 77 on page 170 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 170). 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.
CAUTION: Before removing the transceiver, make sure you open the ejector
lever completely until you hear it click. This prevents damage to the
transceiver.
5.
Using the needlenose pliers, pull the ejector lever out from the transceiver.
