Re: How to remove the cover

If this is a rackmount style... there are 2 or more torx style screws on the bottom side (I'm looking at a 3C16671A) which you will need to remove. If there is an expansion board which slides into a backside slot, then this board will likely need to be removed first too. Also on the backside may be a couple of plastic hooks which help to clip the top on.

Once all retention screws are removed the cover can be lifted backside up some first, then slide towards front some, then clear off. Don't force anything...

I think the cooling fan is the same size as often used on the old 486, Pentium, Pentium II, and some Pentium III heatsink assemblies.

3com 8 port hub not connecting to 2nd pc

Be sure that when you say its a hub that is indeed a layer 1 device which is just passing the signal and data along to all ports. Be sure to check the cable on the second device. At this point it must a straight cable you use to connect the PCs to the Hub. PCs transmit on pins 1 & 2 and Receive on 3 & 6. Hubs are the opposite. So a crossover will not work. You need PC pin 1 & 2 Tx to Hub Pin 1 & 2 Rx and over to PC pin 3 & 6 Rx to Hub pin 3 and 6 Tx. Tx = transmit and Rx = Receive. Also assign an IP address on each machine that is in the same subnet as each other. Such as PC1 mask and PC2 IP address as Subnet Mask This way the 192.168.1 is the same for 8 PCs and the only change is the last number (octet). Also keep the speeds at either 10/100/1000 what ever the product is rated for but always keep the duplex half. Half is good because on a layer 1 hub, everyone is broadcasting at the same time. So you have to have half of all the ports listening at all times.

I hope this helps. My advice is to buy a layer 2 switch.

Hub not working properly

Maybe your hub port is not using auto sense port.

Limited connectivity

A network hub allows computers to be connected together...up to 12 of them in this case...but it doesn't provided any other network services such as DHCP (automatic address assignment). I may be able to provide better information if you can tell me what operating system you're using.

Here's one way to set up a network for file sharing...if you're using Microsoft Windows1.gif XP:

Connect the computers to the hub and turn them all on. You may need to manually assign addresses to the computers, (ask if you need a detailed procedure) but Windows XP will usually assign itself a default address.

On each computer, click on Start -- Control Panel -- System -- Computer Name -- Network ID -- Now give the computer a name and Workgroup name. In order for the computers to share files1.gif, the workgroup names must be identical on every computer.

Next, click on My Computer and Right-Click on Shared Documents -- Sharing & Security -- Share this folder on the network

Now if you click on My Network Places, it should be possible to see the shared folders on the other computers.

Good luck with this....and I hope this is helpful!!
