that depends if the switches port is an autodetect MDI/MDI-X port, if not you will need to use a crossover, but most SOHO switches/routers will autodetect this so you can use a straight cable. but a lot of managed switches ala cisco or HP will not so you will need a crossover cable.

You must use a  straight through cable.

Switch to switch is crossover (fuzzysb is right, jcdesign4u is wrong) unless the switchport is MDI/MDI-X port

If you are using a normal port in one switch and an uplink port in the second switch then you are going to want a straight through cable in most cases.  The uplink port on most SOHO switches is MDI-X port so that you don't need a crossover cable to make the connection.

On many newer SOHO switches the ports are auto MDI/MDI-X so the cables really don't matter that much since the swtiches will figure it out for themselves.

So in summary : either, it depends - the little green light or lack of each end is a good clue :-)

(Agree, always traditionally need a crossover unless one switch has an option for MDI-X (which effectively is just a built-in crossover of the wires on one port) or is auto MDI/MDI-X which means each port automatically sorts it out...)

Net gear FS516 It has auto uplink on port 16 so maybe strandard cat 5 is fine.  But for future if there is no uplink port should I use cross over or standard.

Thanks

With the uplink port standard cat5 is what you want to use, just don't connect to an uplink port on the second switch.  

The only time you need a crossover cable these days is if you are going from a standard port without auto MDI/MDIX capability to another standard port without auto MDI/MDIX capablitiy.
