Install the SFP

1. Wear an ESD-preventive wrist or ankle strap to prevent ESD damage to the transceiver.
2. Insert the SFP into the SFP slot and firmly press it into place.

3. Remove the protective dust plug from the SFP.

4. Plug a fiber-optic cable into the SFP. Note that the SFP works without any additional configuration.

Remove the SFP

1. Wear an ESD-preventive wrist or ankle strap to prevent ESD damage to the transceiver.
2. Disconnect the network fiber-optic cable from the SFP.

3. Pull the safety latch downwards to release the SFP, and then pull it out from the slot.

4. Reinstall the protective dust plug in the SFP’s optical bores and place it on antistatic mat or a static shielding bag.

Note:

1. Do not touch the output pins on the transceiver with your hand.
2. Always keep the protective dust plug on the SFP’s optical bores until you are ready to make a connection.

Caution:
DO NOT point or stare directly into the beam or into the optical port of the transceiver when it is operating, as this can injure your eyesight.

Connection

Use only the SM321A&SM321B together, and SM321A-2&SM321B-2 together for fast and reliable connectivity between switches.

For simplicity, we will take SM321A&SM321B as an example.

1. Switch
2. SM321A
3. SM321B
4. Fiber
