...wall-mounted a Cisco switch larger than 8 ports? Am I missing any consequences from such an installation?
It sounds like they are saying you can only mount the 8-port one on the wall, the other ones should not be, whether you have hardware or not. The reason most likely has to do with heat dissapation, due to component density.
Notice how all the other switches in the series have double rows of ports, except the eight, which has one. Even more telling notice how the 8 port one is the only which has an external power supply, removing the heat from the chassis. Let's see what they say; maybe if you can mount it with a half-inch offset for air-flow they will be "cool" with that.
Lastly, why would having the ports facing to the side be an issue? (see manual page below)
Not sure why but the 200 series manuals have the same verbage but with one extra sentence, shown here:
You think that ports facing up would cause a simliar amount of strain. Though I could see avoiding either and going ports down... Still, I wonder why they took the dependent clause out of the that sentence?

Anything heavier than an 8-port switch would likely pull the included drywall anchors out of the wall.
sg300's are a consumer / soho grade switch and have IIRC fewer mounting bracket options. Try using a 2960 or other (actually Cisco not Linksys) Cisco switch. and I agree there are likely cooling issues if you put it in a small enclosed shelf vertically with too little venting.
Just to play devil's advocate here: how would Cisco know where and how you mounted their switch? It's not like you would be screwing the bottom of the switch to the wall.
I've seen many devices mounted in vertical, wall-mounted racks. If you mount the switch in a vertical rack, which have horizontal rack rails, the switch is still correctly mounted to the rails.
Okay, I talked to Cisco this morning & they did not have an issue with rack-mounting the switch vertically. Not sure why they have that verbage in their manual then. Like a fool though, I forgot to ask them why wall-mounting was a no-no. I imagine it must have to do with weight to housing strength issues.
I've put plenty of larger switches on the wall, including SG300-28Ps. Just turn the rack ears 90 degrees and screw into the switch normally (so the ears are parallel to the top or bottom of the switch), then screw to the wall. I've put them with ports up, down, and to either side, never had an issue - usually it's whatever orientation suits that particular installation. And for the life of me, I can't find any pics of one of these installations...
If there's a stud handy, one ear can screw into that, and an anchor on the other end to "stabilize" the whole thing; usually, I use EZ-Anchors rather than drywall plugs - most versions are rated minimum 50lbs., more than enough for a couple of them to support a 24-port PoE switch.
I've also built a custom vertical "wall rack" with some plywood and 2x4s/2x6s/2x8s (depending on the depth needed - at 3.5" width, a 2x4 fits 2U perfectly; in this pic, 4U = 7" which fits a 7.5" 2x8 with a little room to spare):
switches larger than 8 ports have genuine cooling requirements. make sure there's cooling. the raid array photo in the mesage thread looks scary because with all that plywood there's no apparent airflow. yes, a sound fan/venting arrangement would make the plywood deal reasonable.
I wouldn't use the SG, it's soho-grade (fails quicker, bad management, good way to get hassled by the local IT staff, genetically it's a Linksys (read: junk) design.
I'm guessing the keyhole slots on the back of the switch are perpendicular to the sides with the ports. Thus the recommendation is for mechanical reasons--in theory it could fall off the wall if gravity is not holding the switch down in a narrow end of a slot. I've seen other devices with the same recommendation (for the same reason) such as an APC UPS I was wallmounting recently. I've got a little Cisco SF100D in my garage I had wanted to mount "sideways" for cleaner cable management, but needed to mount up/down as recommended due to the arrangement of the keyhole slots.
I doubt it has anything to do with convection/heat dissipation.
With good quality anchors, this is a wonderful product for what you need (the 2U is cheaper yet).
I have used it in a few installations already without issue. As others have said, make sure the fans can do their thing to keep the inside cool.
I don't know if this was mentioned but just use the Middle Atlantic DBLX/VBLX wall mount lock boxes. You can vertically rack mount the patch panel and switch or just the switch and pull everything into the enclosure. It comes with accessories like temp controlled fans etc. I've put all sorts of gear in these, switches, NVR's, UPS's, etc. in all orientations with no issues. If you want a more cost effective option, VMP makes a lower quality one that will fit the bill. I don't believe it has rack rails but just turn the rack ears 90 degrees on the switch and screw it into the back of the box.

We don't do any residential. We do everything we can to install a purpose-built 19" data rack or cabinet on a fire-rated and painted plywood backboard. We always terminate cabling on patch panels, too. There are tons of options for wall mount cabinets/racks, to include low profile, side mount rails and top mount rails. Your customer and all competent IT professionals will appreciate the quality install. It will cost more, though. We've installed Cisco small business series and Catalyst switches vertically and in side mount configurations. We've had no issues whatsoever. Ensure cabling is supported and there is airflow.

I am late to the discussion and haven't read all of the replies, but this is a simple misunderstanding. Cisco simply meant that they only provided a wall mounting option for the 8-port model. Anything larger is intended to be rack mounted. This has nothing to do with heat or directional mounting. It is just the way they designed the chassis.
If you need to vertically wall mount the switch, they make simple brackets for that.
