The Ethernet ports are autosensing and can automatically adjust to transmit and receive data over straight-through or cross-over
Ethernet connections. For a diagram showing T568A and T568B wiring, see Section 3.2, Ethernet and Console Ports.
NOTE: The default IP address/netmask for the MGT interface is 192.168.2.10/24. For the LAN interface, the default IP address/net-
mask is 192.168.3.10/24. The IP address of the default gateway is 192.168.2.1.
The pin assignments in the male DB9 console port follow the Electronic Industries Alliance (EIA) RS-232 standard. To make a serial
connection between your management system and the console port on the SmartPath EMS, you can use a null-modem serial
cable, use another serial cable that complies with the RS-232 standard, or refer to the pin-to-signal mapping shown in Table 5-3
to make your own serial cable. Connect one end of the cable to the console port on the SmartPath EMS and the other end to the
serial (or COM) port on your management system. The management system must have a VT100 terminal emulation program,
such as Tera Term Pro (a free terminal emulator) or Hilgraeve Hyperterminal (provided with Windows operating systems).
