Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Appendix G – Fiber Transceiver Replacement
Applicability Notice
This appendix pertains to replacement of SFP+ fiber optic transceivers for the DXLink Fiber Transmitters and Receivers
listed in the table on page 12.
The process for removing and replacing transceivers is the same in Enova DGX DXLink Fiber Boards as it is in the
DXLink Fiber units and the same for multimode transceivers (black latch) as it is for single mode transceivers (bright
blue latch).
Items Required
Replacement SFP+ fiber optic transceiver
DXLink Fiber unit or DXLink Fiber board
ESD wristband and cord with alligator clip
ESD shielded bag for storage of removed transceiver
Compatibility Note: In Enova DGX systems using DXLink Fiber technology – the DXLink Fiber Input Board
and its DXLink Fiber TX, Duplex must have the same type of fiber optic transceivers: either multimode or
single mode. The same holds true for DXLink Fiber Output Boards and the DXLink Fiber RX, Duplex units.
Important Information for Fiber Transceiver Replacement
Replacement transceivers must match those replaced: either single mode or multimode.
Adding or replacing SFP+ transceivers should be done only by personnel trained to handle ESD sensitive
parts and assemblies.
If disposal of transceivers is necessary, dispose of them as mandated by your area or country guidelines.
Note: When fiber optic transceivers are not cabled (e.g., for shipping or storage), replace the dust plugs that
originally shipped with the product.

Warning: DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive on page 13).
ESD Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are
properly grounded before touching any internal DXLink Fiber TX/RX materials. Use an ESD wristband and
cord with an alligator clip attached to a good ground source.
