According to what I read, 2 regular ports on seperate switches would need to be connected with crossover cable and a computer connected to an uplink port would need to be connected with crossover cable.
I am confused by that because that is not what I done with my cabling but it works perfectly. Picture at

The port on the far right of the switch is an uplink port and is connected to a computer with straight through cable. The cable between the regular ports on the router and switch is also straight through but it all works!???

So now you have learnt what an uplink port is for you can forget about it again!
In the past there was usually a reversal toggle switch which reversed the polarity of the uplink port so you could use whatever cable you had to hand (straight or X-over).
I'm surprised it actually mentions an uplink port on such a device. They are still used on commercial switches where you may have 1 or 2 gigabyte uplink ports to connect the switches together on a high speed network with the ports themselves only working at 10/100Mbs.

Thats because the switch you have (which is exactly the same as mine) DOES autosense. It's a good little switch (got mine for £3 on ebay!).
The manual clearly states that it doesn't autosense and that you MUST use patch cables instead of crossover yet in another part (actually might be the .pdf from sitecom's website) clearly states that it does support the protocol which autosenses (can't remember the name of it now).
In short, your switch will use anything (beleive me, I've used crossovers, patch in all combinations and my switch is identical to yours).
Also, the uplink port IS NOT the only one. All 5 of those ports will work as uplink. Look at the lines on the switch a bit more carefully and follow the line from where it says uplink - you will notice it actually points to all 5 ports.
Can I ask how you fixed yur switch to that board? - Did you remove the magnetic feet or something?

If you have exactly the same model as me it will have magnetic feet for attaching it to a computer case. You can put 4 screws in the wall and it will stick to them. Even without the screws it would be supported by the cables I have going in.
If you are curious about the other hardware the Linksys access point has a very useful wall mounting bracket. The Netgear router however has no wall mounting facility. The weight of it is supported by 2 small tacs at the bottom just about visible in the photo and the back of it is covered with blu-tac!

I'm also thinking of upgrading to GB switches at some point but at the moment I've got a mini-itx system I'd like to build first.
If you decide to sell your sitecom 5 port, let me know what sort of price your looking for - I might be interested.
Nice tip about the magnetic feet holding onto screws on the board! - Didn't think of that! (But yes it is currently stuck on the side of one of my beasts)

I would be unlikely to sell that switch as I always horde things and I know if I sold it I would have a use for it a week later, sorry.
Could be a while befor I change to GB ethernet. It is not top of my list. A UPS at least 1400VA is needed before that.

Quote from: seanbranagh Yeah. I bought that switch in Maplin and they are still selling strong for £27.99. I know cos I am a manager in one of their stores.

Yeah I know what you mean about hording old IT stuff - I'm the same and yes, a week later, you'll have a need for it! I'm not really in a rush for GB ethernet either. While I'll admit the speed would be nice for moving vmware images around I'm not desperate for it.
Manager of a Mappers store eh? - Can you do discounts?
I went to the Maidstone branch recently, found myself spending a few (60) quid up there.
Incidentally I'm building a double sided UV light box out of an old double sided SCSI scanner I just got off ebay.

All Maplin staff get discount, depends on different products but it is usually very good.
I spent lots of money in Maplin for years before I started working there but the Maplin range is not as exciting now that I am looking at it everyday!

Maplin has changed its product range over the years to cater more for the average person on the street. No longer just a shop for geeks. Thay sell lots of toys and stuff that they didn't when I first became a custommer.

How come they don't put catalogues in WHSmiths now?

Didn't know the catalogues were ever in WHSmith. The website is better anyway, Products and prices change so much the catalogue is always out of date.
That store in Maidstone must be a new store. Their picture on the Maplin site has the new company colours like our store (opened in March.) Personally I prefer the old Maplin look and staff uniform!

UV box is basically a box with a glass panel inside and UV lights. You put a photoresistive board in it with your circuit board design (printed on tracing paper) and close the lid.
Turn on, expose the board to UV light which breaks down the etch resistant photo cover - Except for that covered by the black lines on the print. You then remove it from the box, chemically remove the exposed resistant, then etch the circuit board as normal in ferric chloride.
Mappers have UV boxes but they ain't cheap (small 1 sided £105 - See YA36P).
Yes I preferred the old red colour scheme. The light blue just doesn't look right for mappers. Makes them look a bit wishy washy if you know what I mean..
