902FX/FXE & 904FX /FXE HALF DUPLEX SETUP
All 900 series fiber modules are factory configured for full duplex operation. The setting is controlled
by jumper JP1 on the backplane.

operation is desired, then follow these steps using proper wrist strap grounding techniques:
1. Remove the power & power plugs from the unit.
2. Loosen all thumbscrews & remove all modules.
3. Remove the six screws holding the backplane
4. Remove the backplane.
5. Move the jumper JP1 from position 1-2 to 3-4
6. Re-install the backplane & modules & power plugs.
902/904 Note:
Rev. C & D boards are hard wired for Port1 = HDPLX,
Rev. B & E boards are hard wired for Port1 = FDPLX.
