Step 2 Use the 1/4-inch nut driver to install the six hexagonal standoffs into the mounting holes that previously held the six panhead screws.
Note You can place the rear cover with either of two offsets from the back plane. Assemble the 6.32x1.75 or the 6.32x3.25 hexagonal standoffs for using either offset option.
