of operation for LAN port 1 is located along the right edge of the router case (see Figure
2-2). Locate the switch and set it to NORMAL mode. Then use an RJ-45 to RJ-45 cable
(not supplied) to connect LAN port 1 to your PC' s Ethernet interface.
If your network contains more than four PC' s, you will need first to connect the majority of
your PC' s to each other with an external hub or switch, and then connect that hub or
switch to LAN port 1 on the AIR-104/204 (see Figure 2-1). In this configuration, LAN
ports 2,3, and 4 on the AIR-104/204 can still directly connect to PC' s as described
above.
Connect your PC' s to the external hub or switch. Consult the manufacturer' s
Step 1
instructions for direction.
Connect a node port (one that would normally be used to connect a PC
Step 2
directly) on the external hub or switch to LAN port 1 on the AIR-104/204,
using an RJ-45 to RJ-45 cable (not supplied). Locate the switch that controls
the mode of operation for LAN port 1 on the AIR-104/204, and set it to
UPLINK (this switch is located along the right edge of the router case). See
Figure 2-2. If you are using a special uplink port on the external hub or switch
to connect to LAN port 1 on the AIR-104/204 , then set the mode of
operation for LAN port 1 on the AIR-104/204 to NORMAL.
You may directly connect a console PC running terminal emulator such as HyperTerminal
to the AIR-104/204. To make the connection, use the special RJ-45 to DB-9 cable (Null
Modem Cable) supplied in the package. One end of the cable is a 9-pin DB-9 SCSI
cable; plug this into either the COM1 or COM2 port of the console PC and turn the
screws until finger-tight to seat. The other end of the connector cable is a standard RJ-45
network-cable plug; plug this into the CONSOLE jack on the AIR-104/204.
You may connect either a telephone handset or a fax machine to the AIR-204 (not the
AIR-104) via the PHONE jack. Use an RJ-11 to RJ-11 cable (only one is supplied) to
make the connection.
