1. Ensure that your AT-MR908TX is not connected to a power source.
Note
Electrostatic Discharge Precautions. Static electricity can
damage electronic components of a computer or optional equipment.
To prevent electrostatic damage, observe the following precautions:
Avoid hand contact by transporting and storing products in static-
safe containers. Keep electro-sensitive parts in their containers until
they arrive at static-free workstations. Place parts on a grounded
surface before removing them from their containers. Avoid touching
pins, leads, or circuitry and always be properly grounded when
touching a static-sensitive component or assembly.
2. Remove the four screws holding the blank faceplate on the back panel of
each AT-MR908TX hub and store this faceplate for future use.
3. Slide the AT-MR901 Stacking Module into the back panel port opening, as
shown in Figure 9. Ensure that the module is seated in the internal
connector and the module faceplate is flush with the surface of the back
panel.
