Installing or Replacing the Cables in the UCH2
Caution
Torquing the lead screw to more than the maximum of 20 in-lbs can cause the lead screw to fail.
Note
For the UCH2, as you turn the lead screw clockwise, the outer shroud on the UCH moves to cover the
red line on the top and the black line on the bottom of the UCH. The half circles on the edge of the shroud
close as the shroud fits down over the UCH. Full engagement is indicated by visible metal-to-metal
contact between the UCH and the faceplate (check the half circle cutouts).
Step 5
Repeat Step 1 through Step 4 for the remaining 11 UCH to RF switch card interconnects.
Note
The RF switch cards connect orthogonally across all Universal RF line cards in the system picking up
one connector off each card. It is required to install all the 12 UCH to all the 12 RF switch cards so that
the coaxial cables can be connected even if only one RF line card is installed in the system.
Installing or Replacing the Cables in the UCH2
This section describes how to install and replace the UCH2 cables. The UCH2 universal cable holders
must be used with the Cisco RFGW-10 RF switch line cards. The UCH is designed to stabilize the cables
and hold them in place.
Note
Do not use heat-shrink wrap on quad-shielded cables.
Installing the Cables in the UCH2
Note
Customers who have the new UCH2 cable kits can skip performing this task since the cable kit consists
of coaxial cables clamped to the cable headers.
Cisco cables are color-coded for easy reference and installation. The cable color corresponds to a
specific port on the card.

Note
Other color options for precision miniature video coaxial cables may be available with the RF cable
vendors. You can use any cable color combination but
