Connecting the GRP to an Ethernet Network
This section provides information for connecting the GRP to an Ethernet network.
Figure 3-11 shows the RJ-45 and MII Ethernet ports on the GRP.
Figure 3-11 RJ-45 and MII Ethernet Connections
The GRP has one Ethernet port, which uses either of these port connectors:
• RJ-45 receptacle—An 8-pin media-dependent interface (MDI) RJ-45
receptacle for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u
100BASE-TX (100 Mbps) connection.
• MII receptacle—A 40-pin media independent interface (MII) receptacle that
provides additional flexibility in Ethernet connections. This connector can
also be used for either an IEEE 802.3 10BASE-T (10 Mbps) or an
IEEE 802.3u 100BASE-TX (100 Mbps) connection.
