Replacing an Interposer PCA (Upper and/or Lower)

Note: IF YOU ARE REPLACING AN UPPER INTERPOSER PCA, CHECK TO SEE IF THERE IS A

INSTALLED, TRANSFER THE MODULE TO THE REPLACEMENT PCA.

1. Remove the lower and middle right-side access panels (see “Access for 3800ux/7100ux

cables are oriented properly when reattaching them, in order to avoid damage.
