ETHERNET PORT

Figure 2-4.Dual Hubs

The DNH consists of two identical hub modules in one enclosure. The left side is usually the DataNET ‘A’ Hub and the right side the DataNET ‘B’ Hub. Each hub contains a DataNET Hub board and power supply.

The DNH connects to the Ethernet local area network via the RJ-45 STP connector located on DataNET Hub board. Each of the boards has an Ethernet connection. However, the DNH only the ‘A’ hub Ethernet port is active.

HUB ‘A’

HUB ‘B’’

Active Ethernet Port

Only one Ethernet port is active in the DNH. The wiring connection be- tween the two halves determines which half has the active Ethernet port. A jumper wire visible across pin 1 and pin 2 on the cable connector indi- cates that the side to which it is connected is the active port, which we designate the ‘A’ Hub. The hub that has the inactive Ethernet connection is the ‘B’ hub.

Remember, only one Ethernet port can be active.
