Installing cable management arms
Perform this procedure to install the cable management arms into the enclosure
brackets and onto the rail brackets.
The DAE rear components are redundantly distributed across two sides, A and B.
When viewed from behind, the right half of the system makes up the A-side of the
DAE, and the left half of the system makes up the B-side.
The cable management arms are dedicated A-side and B-side (respective to the DAE
A-side and B-side), and cannot be interchanged. The A-side cable management arm is
distinguished by the offset enclosure retention latch. The enclosure retention latch on
the B-side cable management arm is straight.
Procedure
1. Install the A-side cable management arm:
a. On the A-side, align the long offset retention latch end of the arm with the
enclosure bracket, and carefully insert it into the enclosure bracket until you
feel and hear an audible click.
Both rails have two attachment brackets for the cable management arms.
The lower bracket is for the A-side, and the upper bracket is for the B-side.
b. Swing the extension arm into alignment with the lower rail bracket.
c. Press the short retention latch onto the lower rail bracket.
d. Make sure that you hear the audible click that indicates that the cable
management arm is in place.
