Tip Alternatively, you can cable the header blocks first, then mount them on the RF switch. Do not fully
tighten the header blocks to the RF switch before gently pulling on the cables to be sure that they are
firmly seated.
Cisco cables are color-coded for easy reference and installation. The cable color corresponds to a
specific port on the card. The tables include a column for users to define ports and color definitions.
See Table 4-11 for a list of the cable ports and associated cable color applicable when using MC5X20
dual/quad-shielded 10-color cables.
