The CheetahAccess Internet Gateway includes an LED display on the front panel for 
system power and port indications that simplifies installation and network 
troubleshooting. It also provides 4/8 RJ-45 LAN ports on the front panel, as well as 
one RJ-45 WAN port, one RS-232 serial port and one parallel printer port on the rear 
panel. These ports are described below.
• 4/8 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. Port 8 on the Accton CheetahAccess Internet Gateway offers an MDI-X 
or MDI option by way of separate RJ-45 sockets.
• One RJ-45 port for connection to an xDSL or Cable modem. This port can auto- 
negotiate the operating speed to 10/100 Mbps and the mode to half/full duplex. 
This port only supports MDI-X pin signals, so you will have to use either straight- 
through or crossover cable depending on the port type used on the modem.
• 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.
