Figure 180: Inner Rail Safety Latch Release
Step 20 : Push the chassis back into the rack.
Step 21 : Locate the M5 thumb-screws on the top cover of the enclosure that keep it in place when the
drawer is extended, and unscrew them using a T15 Torx screwdriver. This will allow the top cover
to move freely with the enclosure when the enclosure is removed.
Step 22 : Grasp both handles at the front of the enclosure and pull with even pressure to extend the
chassis out of the rack until it is stopped by the safety latches. Make sure that the top cover
comes with the chassis as it is extended out of the rack. The safety latches will prevent the
enclosure from coming out of the rack completely.
Step 23 : Remove the chassis from the rack.
a. Be prepared to support the enclosure once it is free of the rails by having a second person
or a lift to support the enclosure
b. Grasp both handles at the front of the enclosure and pull with even pressure until the
enclosure will not extend further.
