For the appropriate switchtype entry, see the below chart for description of the switch:
switchType – <model_type>.<motherboard_revision_level> The model types are as follows:
1.x = Brocade SilkWorm 1000 series
2.x = DS-16B / Brocade SilkWorm 2800 series
3.x = DS-8B / Brocade SilkWorm 2400 series
4.x = Brocade SilkWorm 20x0;
5.x = Brocade SilkWorm 22x0;
6.x = DS-16B / Brocade SilkWorm 3800 Series (Includes parity checking on all paths)
7.x = SCB
9.x = DS-16B2 / Brocade SilkWorm 3800 series

SwitchBlade: If the model type shows up as switchblade this is the Blade Server sold by IBM,
which is a 4.x OS switch on a blade that is installed into and IBM server. We have qualified this but do not sale it directly.
The motherboard revision level varies per type. ex: switch
And it's not difficult to see that the output above is Brocade Silkworm 48000.
