Universal Cable Holders

Universal cable holders (UCH) are used to attach the cables to the Cisco uBR10-MC5X20S/U/H cable interface line cards (see Figure 4-5). There are two types of UCH for use with these line cards: UCH1 and UCH2. (For more information, see the Cisco uBR10-MC5X20S/U/H Cable Interface Line Card document.)

Note Universal cable holders are not included in the RF switch cable kits. The UCH are shipped with the Cisco uBR10-MC5X20S/U/H cable interface line card cable.

Caution The Cisco uBR10-MC5X20S/U/H cable interface line card must be used with a UCH for all cable connections to the line card. Failure to use the UCH may cause permanent damage to the line card connectors, resulting in low or no RF output in the downstream or low or no RF input in the upstream.

Header Blocks

See the “Header Blocks” section on page 4-5. An extraction tool ships with the

Cisco uBR 3x10 RF Switch to remove MCX connectors from the header blocks and UCH, if necessary.
