Note: 10/100Base-Tx interface has HP auto-MDIX function and it can check the transmission and
receiving sequence and make configuration. So both MDI and MDI-X interfaces are supported and both
cross line and direct line can be selected.
The Ethernet optical port uses an SFP optical transceiver. Different transceivers are available to suit
multimode, single mode, distance and fiber connector requirements. The input and output side of the
transceivers are marked on the transceiver itself. Refer to the Ordering Information section for
compatible transceivers available form RLH.
