Mounting
Rack
• Secure L-shaped mounting bracket vertically to both sides of each unit, using the provided
screws.
• Carefully slide each unit into the rack mount bracket. Secure with screws. The rack mount
bracket may provide up to two bays.
Only the standard mounting brackets are NEBS compliant. The recessed brack-
ets are not NEBS compliant.
To conform to the NEBS Seismic Zone 4 requirements, the bracket must be
secured, using screws specified by the rack manufacturer, to a NEBS Seismic
Zone 4 compliant rack. Such screws are not provided with the bracket kit.
Note:
For more information, refer to the Skylight LX User Manual.
• Attach the included rubber feet to the bottom of the unit for added stability when placing it
on a desktop or other flat surface.
•
Ensure the fan airflow is not blocked.
