Lantronix TN-QSFP-40G-xx User Guide QSFP+ Installation Cautions • The QSFP+ tranceiver module is keyed to only be installed one way. However, if forced the wrong way, damage may occur. • Avoid getting dust or other contaminants into the fiber bore of the QSFP+ transceiver module. • Clean the optic surfacees of the optical fiber before you plug them back in to the optical bores of another QSFP+ tranceiver module. • Each port must match the wavelength specifications on the other end of the cable, and the cable must not exceed the specified cable length for reliable communications. Installing a QSFP+ Module 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis. 2. Remove the QSFP+ transceiver module from its protective packaging. Note: Do not remove the optical bore dust plugs until directed to do so in a later procedure. 3. Check the slot orientation. Note that for some devices (e.g., S4224) some slots are "upside down" compared to other slots. 4. Position the QSFP+device at the desired installation slot, with the label facing correctly. 5. Carefully slide the QSFP+ device into the slot, aligning it with the internal installation guides.

Ensure that the QSFP+device is firmly seated against the internal mating connector. To verify that the QSFP+ is seated and latched properly. a) Grasp the QSFP+ by the sides and try to remove it without releasing the latch. b) If the QSFP+ can not be removed, it is installed and seated properly. If the QSFP+ can be removed, reinsert it and press harder with your thumb; repeat if necessary until it is latched securely into the socket. 7. Connect the fiber cable to the fiber port connector of the QSFP+ device. Make sure the QSFP+ release latch is in the up (closed) position when you insert the cable connector into the QSFP+. 8. Remove the dust plug from the connector. Save the dust plug for future use. 9. Attach an appropriate cable into the QSFP+ module port. 10. Attach the other end of the cable into the other device. 11. Observe the status LED(s). See the related manual for details. 33684 Rev. D https://www.lantronix.com/ Page 8 of 16
