Hardware Description
5
• 4 RJ-45 ports for connection to a 10BASE-T/100BASE-TX
Ethernet Local Area Network (LAN). These ports can
auto-negotiate the operating speed to 10/100 Mbps, the mode
to half/full duplex, and the pin signals to MDI/MDI-X
(i.e., allowing these ports to be connected to any network
device with straight-through cable). These ports can be
connected directly to a PC or to a server equipped with an
Ethernet network interface card, or to a networking device
such as an Ethernet hub or switch.
• One RJ-45 port for connection to a DSL or cable modem
(WAN). This port also auto-negotiates operating speed to
10/100 Mbps, the mode to half/full duplex, and the pin signals
to MDI/MDI-X.
• One RS-232 serial port to connect to an ISDN Terminal
Adapter (TA) or to a PSTN analog modem.
• One parallel printer port that can be connected to a printer.
This printer can then be shared by any LAN users.
