5. Re-install the left and right end caps (See Figure 24 on page 46).
The left end cap has indicator windows that align with the status LEDs (light-emitting diodes) on the
edge of the enclosure.
a) Ensure that the serial number on the left end cap matches the serial number on the left flange
("ear") on the front of the enclosure.
b) Fit the slot on the top of the end cap over the tab on the flange.
c) Rotate the end cap down until it snaps into place.
d) Ensure that the inside surface of the end cap is flush with the flange.
