rack switch ports on back JR 04-13-2007

I am looking for a gigabit ethernet switch for a rack mount unit. For
some reason most of the rack mount switches I see have the ethernet
connections on the front. Not sure why that is as how many rack units
want to run the cables for all their computers to the front of the
rack? Perhaps they are just meant for either desktop units or rack
and some people prefer desktop units to have the connections where
they can be reached from the front. Is there models that have the
ports on the back? Any suggestions would be appreciated. Need only 8
ports per rack but more is fine.

Thanks.

JR

That's for the simple reason to be able to patch them easily when the front
door is open.

Every single one that I know.

You might just mount your switch on the backside profile rails of your
rack. Given that your rack has those, of course. But it is generally a
better idea to leave the switch and all of its controls and jacks facing
the front side. What exactly is your problem with this idea - the routeing
of the patch cable?

The racks in common use it large facilities have rails front and rear
in the cabinet. I've faced the RJ45 field and the switch on the rear
rail, facing to the back. (because that's where the cable bundle was).
The servers faced front.

The front and rear rails exist because servers can be heavy and need
support front and rear.

Most everything from Cisco can be mounted either way just by attaching
the ears to the other side. Usually you have to move one extra screw
per side to do this.

If you have a rack of network gear, the front is much more convenient
than the back. If you have a rack of servers, the back is probably
more convenient.

Most rack mounted switches allow you to fix the mounting brackets to the
back of the switch ... effectively mounting the switch with the switchports
facing inward.
