Configuring mart Management Functions
The 4/5/8 Port 10/100/1000M Gi abit Ethernet Desktop Smart Switch offers you a very
convenient and secure way to configure your Switch for VLAN, Priority and Port-Mirroring
function through a RS-232 cable that connects its console port and the host PC. Using
Windows HyperTerminal (on Windows 9 /98/NT/2000/XP) or utilities such as Telix or
Procomm (on DOS environment), you can easily configure the Switch for VLAN, Priority
and Port-Mirroring function.
But before you can actually configure the smart management functions by your host PC,
you should establish a proper RS-232 cable connection between the console port of your
switch and the COM port of your host PC.
Makin RS-232 Cable Connection to the Host PC
The way to make a RS-232 cable connection is simple. Just prepare a proper RS-232 cable
to connect the console port of your 4/5/8 Port 10/100/1000M Gi abit Ethernet
Desktop Smart Switch and the COM port (either COM1or COM2) of your host PC.

Note:
After you have established a RS-2 2 cable connection between the 4/5/8 Port 10/100/
1000M Gigabit Ethernet Desktop Smart Switch and your host PC, if your 4/5/8 Port 10/
100/1000M Gigabit Ethernet Desktop Smart Switch or the host PC is not powered on,
you should power them up before you can configure smart console functions.
Using Windows HyperTerminal for mart
Configuration of VLAN, Priority ,and Port-
Mirroring
After you have properly established a RS-232 cable connection between the console port of
4/5/8 Port 10/100/1000M Gi abit Ethernet Desktop Smart Switch and the host PC. You can
now begin configuring station ports for the smart console functions. Generally, you can use
Windows HyperTerminal (on Windows 9 /98/2000) or utilities such as Telix or Procomm (on
DOS environment) to access the Switch and perform smart configuration. In the following
section, we will offer you a configuration example using Windows HyperTerminal on Win-
dows 9 /98/2000 platform.
Run Windows HyperTerminal utility
Step 1:
After the RS-232 connection is properly made, you should then run Windows HyperTerminal
by accessing Start menu/Accessory/Communication/HyperTerminal.
Step 2:
The HyperTerminal window appears with a dialog box to prompt you to enter a name
and choose an icon for the connection.
Step :
