Chapter3 Basic Installation
3.1 Connecting the Hardware
1. Make sure that your USB devices are switched off and that the Server’s Power Adapter is disconnected.
2. Connect the USB devices to the USB ports with the USB cables.
3. Connect the Server to the network with a twisted-pair category 5 cable, 10baseT or 100baseTX.
4. Turn on the USB devices and make sure they are ready for use.
5. Connect the Power Adapter to the Server. The power indicator will light up and USB1 and USB2
indicators will flash in turn. When the Link indicator lights up, the Server is correctly connected to the
network. When the USB1 and USB2 indicators stop flashing, the Server is ready to work.
6. If you connect USB HP printers to the Server, please press the Init button for 3 seconds on the Server
once to print a page of Server configuration report.

3.2 Assigning an IP Address to the Server
3.2.1 Preliminary
• If you have a DHCP server on your network, your Server will receive an IP address automatically. The IP
address will then appear on the Control Center or on the page of configuration report that you printed
earlier. If your DHCP server does not give an IP address to the Server, the Server will use the Factory IP
address: 192.168.1.100.
• If you are not working in a DHCP network, you need to manually set the Server’s IP address.
• If you are connecting multiple MFP Servers, and not using a DHCP server on your network, you will need
to disconnect the other MFP Servers if they are using the default IP Address (192.168.1.100) to avoid IP
conflicts and configure the server.
3.2.2 Ethernet Address
You do not need to know the Ethernet address of your Server to assign an IP address to it. The Control Center
will automatically search for Servers and list their Ethernet addresses.
3.2.3 IP Address
Unless you are assigning an IP address using DHCP, you must obtain an unused IP address from your
network administrator.
3.2.4 Methods for Setting the IP Address
You can set the IP address of your Server using one of the following methods, depending on your network
operating environment:
• Automatic IP Address Assignment
• Manual IP Address Assignment
3.2.5 Host Names and Host Name Rules
The Host Name of the Server defaults to be “NP3680” (for NP3680). If you put two or more Servers in your
local area network, to avoid using the same Host Names you have to change the Host Names by using the
Control Center or the Server’s web pages. If your Host Name is longer than 15 characters, the Server uses
only the first 15 characters.

NP3680 User Guide 11
YML838 Rev 2
3.2.6 Setting the IP Address Using DHCP
Follow the instructions below to get an IP address using DHCP:
1. Edit or create a scope in the DHCP manager of the DHCP daemon. The entries included in this scope
should contain the following parameters:
• range of IP addresses
• subnet mask
• default router IP address
• DNS server IP address
• lease duration
2. Activate the scope. The Server automatically gets the DHCP parameters. If you are using DNS, you may
include at least one DNS server IP address in the DHCP scope or manually set the DNS server IP address
using Server’s web pages or the Control Center.
3.2.7 Setting the IP Address Using the Control Center
1. Install the Control Center. The Control Center is available on the Product CD.
2. Start the Control Center and Auto-searching Server window will appear.

12 NP3680 User Guide
YML838 Rev 2
3. If the tool finds multiple Servers in your local area network, then you have to select one Server from the
Server List.
4. Double click the server in the list and enter the Server’s administrator (default: admin) and password
(default: admin).
5. After you have logged in successfully, select the TCP/IP tab. The Set IP Address dialog appears.
6. Click the button corresponding to your choice of IP setting method (static or dynamic using DHCP). When
assigning a static IP address you also have to define Subnet Mask and Default Gateway. If you choose
Automatically get IP by DHCP, you can use desired DNS by clicking the Manual DNS button and manually
assigning a DNS.
7. Click Apply to save your settings and the Server will reboot.
8. You have now finished the procedure of setting the IP address.

3.2.8 Setting the IP Address Using the Server’s Web Pages
1. If you don’t know the current IP of you Server, follow Step1~Step4 of Set the IP Address Using the
Control Center.
2. You can see the IP address of you Server in the Server List. Open a Web Browser and enter the Server’s
IP address or click the Home Icon of the Control Center.
3. Go to the web page and click the CONFIG menu icon.
4. Enter administrator (default: admin) and password (default: admin).
