not to mention that they also change how much the devices protrude from
the rack when using the mounting kits. I think theres almost an extra
inch of front lost on a 2960 compared to 2950 series. This means moving
the vertical mounting bars backwards in cabs which you were 'okay with' 
before if you still want e.g. your fibre to be okay.
