Step 17 : Test for binding in the extension of the arm by gently pulling the enclosure out of the rack,
ensuring the cables extend properly and that the system doesn't bind at all. If it does, examine
the point at which the binding occurred and adjust the seating of cables in the baskets, check
the connections to the rails, and examine the joints of the arm to ensure that they are all
functioning properly.
Step 18 : Secure the chassis top cover to the rack using the captive M5 thumb-screws as shown in the
following image. Use a T15 Torx screwdriver, and tighten the screws to 3.38-3.61 Nm / 30-32 in-
lbf.

Step 19 : Now that the chassis is installed, test the installation by sliding the enclosure in and out of the
rack a minimum of three times. If the enclosure binds, catches, or displays any incorrect motion
or behavior repeat the installation.
Step 20 : 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. The safety latches will prevent the
enclosure from coming out of the rack completely and the cover will remain in the rack attached
to the rear alignment brackets.
Note: Adjustments of the vertical rack rails may be required to fix any issues that
may occur.
