Interfaces and Connectors

Connect the LAN to connector X3. Table 3-23 contains the connector assignments.

The board has a 50-pin edge connector to the system, two MW jacks (8-pin and 10-pin, shielded) to the LAN, and one shielded Mini-DIN jack (6-pin) for the V.24 interface.

X1: 50-pin to system
X2: 6-pin shielded Mini-DIN jack for V.24, see Section 3.4.16

The following connections are pre-installed for connecting a LAN:

X3: 8-pin MW jack for LAN 10/100 BaseT, RJ45 jack (twisted pair)

Figure 3-22 HXGS Interfaces (S30810-Q2931-X/X100)

The transmission medium for 10/100 BaseT" is a twisted pair cable.

To physically connect the cable to Hicom Xpress @LAN HXGS (OfficeCom and OfficePoint), use the 8-pin MW jack X3 provided on the MDF side of the board; see Figure 3-22.
