6�4�3 LPS in OSP Cabinet Application
For operations where ambient temperature reaches 65°C maximum, forced air cooling is required. The LPS36 mod-
ule has some flexibility to operate in high ambient temperature without using the standard LPS fan tray by utilizing
the internal airflow inside the OSP cabinet.
Thermal testing must first be conducted on the cabinet with test results reviewed and approved by Alpha.
To determine the external airflow required for a given load, follow the graph below.

THERMAL MANAGMENT WITH FAN TRAY
A MINIMUM OF 1/2 RU (7/8") AIR GAP ON BOTH AIR INTAKE AND EXHAUST
SIDES OF THE SHELF ARE REQUIRED FOR PROPER COOLING.
THIS APPLIES TO ALL INSTALL ORIENTATIONS.
