CAUTION: Do not bend ber-opc cables beyond their minimum bend radius. An arc
smaller than a few inches in diameter can damage the cables and cause problems that
are dicult to diagnose.
4. Remove the cable connected to the transceiver (see
Disconnect a Fiber-Opc Cable ). Cover the
transceiver and the end of each ber-opc cable connector with a rubber safety cap immediately
aer disconnecng the ber-opc cables.
5. If there is a cable management system, arrange the cable in the cable management system to prevent
it from dislodging or developing stress points. Secure the cable so that it does not support its own
weight as it hangs to the oor. Place excess cable out of the way in a neatly coiled loop in the cable
management system. Placing fasteners on the loop helps to maintain its shape.
CAUTION: Do not bend the ber-opc cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems that
are dicult to diagnose.
6. To remove an SFP56-DD, SFP, SFP+, XFP, a QSFP+, or QSFP56-DD transceiver:
a. Using your ngers, pull open the ejector lever on the transceiver to unlock the transceiver.
Note that QSFP-DD and SFP-DD transceivers don't have ejector levers, they have a pull tab
instead which can be used to unlock and remove the transceiver.
CAUTION: Before removing the transceiver, make sure that you open the ejector
lever completely unl you hear it click. This precauon prevents damage to 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.
CAUTION: To prevent ESD damage to the transceiver, do not touch the connector
pins at the end of the transceiver.
