Header Blocks

The header blocks are installed on the Cisco uBR 3x10 RF Switch. Individual cables are attached to the MCX connectors in the header blocks (see Figure 5-4). The header blocks used in this cabling solution are slightly beveled at the top for easy identification. In addition, the alignment pins on the header blocks are offset, preventing you from accidentally connecting the header block upside down.

MCX Connectors and F-Connectors

MCXFP—75-ohm MCX connector available from WhiteSands Engineering or alternate. This connector is attached to the end of the cable that terminates at the Cisco uBR 3x10 RF Switch.

ASFP or alternate—F-connectors available from WhiteSands Engineering. This connector is attached to the end of the cables that terminate at the upstream and downstream ports on the cable interface line cards. The output cabling kit includes 13 F-connectors to use for modification or repair.

Note An extraction tool used to remove MCX connectors from the header blocks is shipped with the RF switch.
