QSFP+ optical transceiver
The QSFP+ ports accept supported QSFP+ transceivers. The QSFP+ optical
transceiver provides an MTP cable connector for connecting to external ports.
CAUTION:
CAUTION:
To install a QSFP+ optical transceiver in a QSFP+ port, complete the following
steps.
Note: To avoid damage to the cable or the SFP transceiver, do not connect the
cable before you install the transceiver.
1. Remove the safety cap and pull the locking lever into the down (unlocked)
position.
2. Insert the transceiver into the port until it clicks into place. Use minimal pressure
when you insert the transceiver into the slot. Do not use excessive force when
you insert the transceiver; you can damage the transceiver or the QSFP+ slot.
The transceiver has a mechanical guide key to prevent you from inserting the
transceiver incorrectly.
3. Pull up the locking lever to lock the transceiver into place.
4. Connect the fiber-optic cable.
To remove a QSFP+ optical transceiver, disconnect the fiber-optic cable, and
pull down the locking lever to release the transceiver. After you remove the
transceiver, replace the safety cap.
