1. Wear an ESD-preventive wrist or ankle strap to prevent ESD damage to
the transceiver.
2. Disconnect the network ber-optic cable from the transceiver.
4. Reinstall the protective dust plug into the transceiver’s optical bores
and place it on an antistatic mat or in a static-shielding bag.
3. Pull the safety latch backwards to release the transceiver, and then pull it
out from the slot.
Note:
1. Do not touch the output pins on the transceiver with your hand.
2. Always keep the protective dust plug on the transceiver’s optical bores until you are ready to make a connection.
Caution:
DO NOT look into the beam or the optical port of an operating transceiver. This may cause eye injury.
Keep the device away from water, re, humidity or hot environments.
Do not attempt to disassemble, repair, or modify the device. If you need

Note: When plugged into a 100G QSFP28 slot, the module operates at 100 Gbps. In a 40G QSFP+ slot, set byte 98 on page 00h from FF to 00 to run at 40 Gbps. When
plugged into a TP-Link device's 40G QSFP+ slot, the module auto-downgrades to 40 Gbps—no action required.
