Okay - quick but important question!

Is it okay to install an unmanaged switch vertically? (model SG100-24)

And what about a small business router? (model RV042G)

I am guessing that it's fine for the switch but not the router.

I ask because I have to do an install in a VERY small area and I have to build a custom cage with built-in fans to put AV receivers and sky decoders in along with a few network components so anything I can put on its side is useful! It's going to be a 3D maze-cum-birds nest but there is no-where else I can install this stuff in the house sadly.

I wish I could install the sky decoders vertically but apparently the hard disks are made so badly that they can't be installed upright which is very unusual for a hand with disk!
