Two Catalyst 3560-X switches - anything required to connect the two together?

I have one 3560-X switch currently in production. I bought another one to expand. Can I simply install it in the same rack and connect the two with a standard patch cable? Is a crossover cable required? Any special port configuration required? My "manual" for the 3560 keeps referencing the 3750-X. I don't have any "Stackwise" or "Stackpower" ports on the back. I'm sorry for posting such a simple question but what surprises me even more is I cannot find any information online in the last hour about this. I called support and they told me to come here.

 

Thanks!

To confirm though, a straight

To confirm though, a straight-through OR crossover cable will work to connect the two switches and no settings need to be configured on the two ports I use? 

You can connect using either cables because, by default, MDI/MDI-X is enabled.  However, if someone hard-codes the speed and/or duplex settings, MDI/MDI-X is disabled, hence, my recommendation you use cross-over cable instead.

It is better to use a cross-over cable so in case someone likes to get pedantic and hard-code the speed/duplex setting you won't panic.

You have a 3560-X and like the 3750-X you should have StackPower.  StackPower will depend on whether or not you have a redundant power supply installed at either one of the units. If you didn't exercise this option, then you don't need to.  

 

As to the accuracy of the documentation, yes, Cisco's been dropping-the-ball lately with documentation ... and from what I've heard, it's going to get worst as more and more people leave.

Thanks Leo. I'm shipping it

Thanks Leo. I'm shipping it across the country and they're hoping to just plug-and-play with it. I will just ship an odd-colored crossover cable with it, and tell them to just connect the two switches with that cable -- any port to any port (there are no VLANS).

If I'm missing anything please let me know. Thanks for the quick reply too!

Oh wow. That's an impressive

Oh wow. That's an impressive how-to! Luckily the switch is just a basic install and nothing fancy. To confirm though, a straight-through OR crossover cable will work to connect the two switches and no settings need to be configured on the two ports I use? Thanks again Leo!

this issue might me the original switch must have been configured if you can share the configuration we can easily resolve this issue if the cable is correct
