APPENDIX B

DELTX-UI, DELFX-UI AND DELF3-UI

SPECIFICATIONS

The DLE2X-MA supports three Fast Ethernet Interface Modules:

•DELTX-UI

•DELFX-UI

•DELF3-UI

This appendix provides the specifications for these modules.

B.1 DELTX-UI

The DELTX-UI uses an RJ45 connector supporting Unshielded Twisted Pair (UTP) cabling.

The slide switch on the DELTX-UI determines the crossover status of the cable pairs. If the switch is on the X side, the pairs are internally crossed over. If the switch is on the = side, the pairs are not internally crossed over. Figure B-1 shows the pinouts for the DELTX-UI in both positions.
