3.2 Fiber optic link
Each pair of LRXI Industrial Fiber Extenders are supplied together with SFP fiber optic units of your choice (single or multi-mode).
The fiber optic cable used must match the SFP type and also be of a suitable type for the distance being covered. See
for details.
Note: In order to maintain a high level of confidence in the fiber optic link, the SFP’s used must be those supplied by Black Box.
If alternative parts are used, the system will detect this and will flash the front panel LNK indicator.
3.2.1 To make the fiber optic link
IMPORTANT: Ensure the power supply is off/disconnected before inserting or removing an SFP module.
1 Remove the SFP module from its protective packing and insert it fully into the empty slot on the LRXI unit. The LRXI local
unit slot is located on the front panel; the LRXI remote unit slot is situated on the rear panel.
