3.3.3 10/100 BaseT Ethernet Connections
3.3.3.1 10/100 BaseT Ethernet M
anagement (M&C) Port, RJ-45 (Standard)
The 10/100 BaseT Ethernet connection is a standard 8-pin RJ-45 modular port.
This connector is present on the base modem assembly and is used for M&C
purposes. It is used to connect a UTP cable to an Ethernet hub, router, switch,
PC, etc., and to upgrade CDM-570L base modem firmware.
See Table 3-4 for the t
ypical port pinouts.
3.3.3.2 10/100 BaseT Ethernet Traffic Port, RJ-45 (with Optional IP Module
only)
This second 8-pin RJ-45 modular port is present only if the optional IP Module
is installed. It is used to connect a UTP cable to an Ethernet hub, router, switch,
PC, etc., and for Ethernet traffic, management of CDM-570L and IP Module
functions via Telnet/HTTP/ SNMP, and to upgrade CDM-570L IP Module
firmware.
