Belkin F5D8231-4 - N1 Wireless Router Quick start guide

F5D8231-4 Operational Principle
1. FUNCTION DESCRIPTION
The Belkin F5D8231-4 Wireless-11N Router is a next generation Router with
built-in wireless access point (AP), 4-port Fast Ethernet (10/100Base-T) switch for
LAN, and 1 Fast Ethernet port for WAN connection. The Router operates on
2.4GHz frequencies, which conforms to the IEEE 802.11b/g wireless standards,
and the draft 802.11n specification. The router features Atheros’s
draft-802.11n-compliant radio in 2x3 (TX/RX) configuration offering breakthrough
performance and enhanced coverage to it’s WiFi network. The Router is to be
used with either a Broadband ADSL or Cable Modem via the WAN port to share
broadband connections with up to 4 computers via the LAN ports and 32
computers via the WLAN. Each LAN port supports 10/100 Base-T Networks with
auto sensing and switching compatibilities. The Router’s Next Gen EZ install
software operates on Microsoft’s Windows 2000 and XP, and on Mac OS X. The
Router can be configured through a web-browser interface. The product is
designed for the home and small office and will be available through major
retailers and online retailers.
The F5D8231-4 uses the Marvell 88F5180N CPU as the micro-controller and
it offers a memory configuration of 4M Bytes Flash and 32MBytes DDR RAM
This device derives its power from a 12V DC power adapter which needs to
be converted to 3.3V, 2.5V, 1.5V, 1.4V and 1.2V.
The functional requirements of the system are as follows:
1. CPU Marvell 88F5180n 333MHz
2. CODE SIZE 4Mbyte
3. SDRAM 32Mbytes
4. Switch Marvell 88E6061
5. WAN Port One RJ45 port with auto negotiation
6. LAN Port Four RJ45 port with LED and auto negotiation
7. Power Adapter DC 12V/1.2A
8. LEDs Refer to Table 1
9. Reset button Reset to factory default by pressing 5 seconds
11. EMC Class–B
12. PCB Layout 4 layers

Status
Blinking Amber Problem with wireless computer connecting properly
to the Router (Pending feasibility confirmation with
ODM) Our suggestion now is
when there is at least one wireless computer cannot
access the router, then blinking amber.
Need marvell’s support to see if marvell driver can
report some of wireless computer is power on, but
has problem to associate. This may be not doable.

Operating Frequency in Europe: 2412-2472 MHz

3. Operational Principle
1). Power on the DUT, then connect WAN port with PC1 and LAN port with PC2.
2). Set PC1(Connected with WAN) IP as:
IPAddress:10.10.10.11;
Subnet Mask:255.255.255.0;
Gateway:10.10.10.1.
3). PC2(Connected with LAN) can get IP address from F5D8231-4 and the default
IP subnet is 192.168.2.0. So PC2’s IP address may be 192.168.2.x.

4). Open the Internet Explorer and type theAddress: 192.168.2.1. Then press
“Enter”.
