Remove and Replace the Lamphouse
The lamphouse (505-1514-xx) fastens to the bottom case. It provides an alignment mechanism for the
lamp module to ensure precise beam focus into the optical path.
The lamphouse includes the safety switch and thermal switch.
Two cooling fans fasten to the rear side of the lamphouse. If you need to replace a fan, refer to Remove
and Replace the Cooling Fans on page 27. If you're removing the lamphouse to access another FRU,
you don't need to remove the fans.
