SMC Barricade - Win2000 ICS Network Mystery
alohapat Sep-10-01 10:20 PM
I understand that the SMC Barricade 7004BR should be able to function as a switch. I am attempting to replace an ailing hub (that is acting as a...repeater?) with the 7004BR, but cannot seem to detect/see any PC from any other. This is frustrating, since my primary goal is file sharing with internet access being secondary.

The set-up in a nutshell:

OLD Set-up (internet & file sharing works fine):
3 900mhz Win2K Dell PCs connected to a Linksys EF2H16 16-port 10/100 Hub with ICS activated on PC#1
D-Link DSH-5 10/100 Hub (acting as a...repeater?)between Linksys (main hub) and PC#3. Connection from main hub leads into uplink port on the D-Link.
*Dial-Up internet connection

NEW Set-up (Internet okay, but can't see other PC's):
Simply replaced D-Link DSH-5 with SMC7004BR Barricade. Since there is no uplink port, tried to connect it WAN port.

Any ideas?

A repeater is used to extend the distance limits for network cables. Don't really see why you need it unless the pc is farther than 328 ft from the others.

I am not sure I understand your setup or the need for a "repeater" switch in the old one. To cascade hub/switches simply connect a regular port to an uplink port with a straight-thru cable or connect two regular ports with a crossover cable (for more information see What is an uplink port and what are the ways to connect two hubs/switches together? at http://duxcw.com/faq/network/uplink.htm). However, in this case all you have to do is retire the 16-port hub and DSH-5 switch and plug all of your PCs directly into the Barricade. The PCs should have their IP/TCP Properties set to obtain their IP addresses automatically from the DHCP server in the Barricade. Any other DHCP servers should be disabled. IP addresses should be refreshed using ipconfig. Larry

Larry & BBates,

Thank you for the quick response on such a tragic day. I guess I should clarify the situation furter and rephrase my question(s):

My reason for doing this is to enable my laptop to connect to our office network for file and internet sharing.

The problem is that the main hub is so far away from my workstation, >200-250 ft. or so, that our cost to install a second cable to allow me to connect my laptop to the network hub directly is prohibitive. Basically, I am trying to allow 2 PCs to share the single cable that connects the hub to my work area. To do this, I thought I'd try to "split" the connection from the existing cable by plugging it into the Barricade's WAN port, and then connecting my desktop and laptop to the standard ports in front.

1) Can the Barricade's WAN port be used as an uplink port?

2) If not, would a crossover cable do the trick?

3) If a crossover cable is the answer, would I be able to use an RJ-45 coupler on one end of the 200 ft.+ straight-through and a short length of crossover on the other to achieve the crossover effect? Remember, I am trying to avoid the hassle & expense of purchasing, crimping, and laying another cable.

Thanks in advance!

Use a regular port on the Barricade and the uplink port on the hub or another combination of cables and regular/uplink ports described at http://duxcw.com/faq/network/uplink.htm. That is, plug everything related to the local network, which includes the hub, into the front of the Barricade.

>3) If a crossover cable is the answer, would I be able to use an RJ-45 coupler on one end of the 200 ft.+ straight-through and a short length of crossover on the other to achieve the crossover effect?

See above link first. Yes, if the cables, especially the long cable, are made correctly and with the right kind of cable and plugs. The maximum, total length cannot exceed 100 meters. Be sure the coupler is rated CAT 5 or higher.

Consider swapping location of the hub and Barricade. A switch is faster than a hub. If you have broadband (cable/DSL) access, use the barricade (WAN port) to connect everyone to the Internet, including those on the hub. Change that face to a smile. Larry
