To install the ears:
1. There are screws that secure each side of the SWE-8 top cover. Using a #1
or #2 Phillips screwdriver, remove the three screws closest to the front
panel from one side of the unit. Refer to the diagram following step 3 for a
detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
by the screws in step 2.
3. Secure the ear to the unit with the three screws from step 2 as shown in the
following diagram.
Ear Attachment for Rack Mounting
Stacking
Four “feet” are provided with the SWE-8 so that if the unit is not rack mounted, the
rubber feet can provide stability when the unit is placed on a flat surface or stacked.
