Step 1: Determine installation 
location

The 3Com X5 is a compact device that does not require rack 
installation. It should be placed in a location with adequate ventilation 
and should not be blocked or covered by any other devices or objects.

Step 2: Connect the power

Use only the 3Com-supplied 5V DC power supply. Do not use other 
power supplies with the X5 device.

Plug the power supply into the input on the front of the X5 device.

2

Plug the power supply into an AC outlet, power strip, or UPS.

Note: 

The X5 may take several minutes to boot up. When the top 

Status LED is solid green, the device is powered up and ready to use. 

Step 3: Complete initial setup 
configuration

Gather your network information. Use the Network Information 
Table (
Table 1) to record the required IP addresses for reference 
during setup.

2

Configure your computer’s network connection to receive an IP 
address by DHCP.

3

Use an Ethernet cable to connect your computer to the X5 LAN port. 
Your computer will receive an IP address from the X5 device.

4

With your computer’s internet browser, connect to the X5 default 
LAN address (

https://192.168.1.254

).

5

The Out of Box Experience (OBE) wizard opens.

A

Accept the default security level of Level 2.

B

Specify the SuperUser account information at the prompt:

User  Name

Password

Confirm password

C

Accept the default settings in the rest of the Setup Wizard by 
clicking 

No

 when prompted.

D

You may need to update your WAN settings on the Virtual Inter-
faces setup screen.

If you use DHCP to connect to your Internet provider, accept 
the default WAN settings.

If you use PPPoE, enter your ISP user name and password.

If your ISP assigns a static IP address, select 

Static

 as the 

external interface type and enter the IP address, subnet 
mask, and default gateway information.

E

Define additional user accounts if desired.

At this point, your initial configuration of the X5 is complete. You can 
use the LSM to change settings in the future.

Note:

 When you connect to the LAN address, your browser may 

display a security certificate warning. Accept the certificate and 
continue with the configuration procedure.

Step 4: Connect the X5 to the Internet

Use an Ethernet cable to connect the X5 WAN port to your router. If 
the X5 is configured to receive its WAN IP address by DHCP, PPPoE, 
PPTP, or L2TP, the device connects to your service provider. This 
may take a minute or more.

2

Check the status of the external virtual interface with the LSM. If 
active, the interface will be in “Up” status, and will have an IP 
address.

3

Use your web browser to connect to an external URL, such as 

http://www.3Com.com

. If you can see the web site, your Internet 

connection is active, and you can register your device and configure 
other features of the X5.
