Attach And Adjust The Strain Relief Ferrule - HP 27115A Installation Manual

Attach and Adjust
the Strain Relief
Ferrule
Note
Once the
PCA,
with the attached cable, is in the
CIO
card cage, you will need to
install a strain-relief ferrule (unless it is already installed on the cable). When
properly connected to the
CIO
grounding bus (part of the
CIO
card cage), it
provides strain relief and guides the fiber-optic cable out of the card cage. The
computer power should be switched off for this procedure. Figure 2-5 illustrates
installing a strain relief ferrule.
If the strain-relief ferrule is pre-assembled on the cable, you may still need to
adjust it for proper distance from the cable end. Reverse the ferrule in the
grounding bus (as in step 1) and proceed to step 2 below.
Note the twist in
the fiber-optic
cable.
