Cisco Cisco uBR-MC3Gx60V-RPHY Broadband Processing Engine Installation Guide

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 

 for a list of the cable ports and associated cable color applicable when using 

MC5X20 dual-shielded cables or quad-shielded cabling.

The recommended cable colors are the same for the UCH1 and UCH2.

Precision miniature video coaxial cables come in various colors, and you can use any cable color 
combination. However, when you are connecting the Cisco uBR10-MC5X20S/U/H cable interface card 
to the Cisco RF switch, we recommend that you install the cables in the UCH as shown in 

listed in 

. 

To replace cables or install new cables in a UCH2, complete the following steps:

Use the T-10 TORX driver tool to loosen the lock bar on the side in which you want to install a cable. 
(See 

Use a flathead screwdriver as a lever to slide open the lock bar. (See 

Remove 

the ESD cap from a cable (see 

 and 

) an

d place it into the hole in the UCH2. 

(See 

 to determine the correct color and location for each colored 

cable.

Insert and wiggle the connector into the hole. 

The cables fit loosely in the holes, and are not locked into place until the lock bar is closed in 

.

Repeat 

 and 

 for the remaining cables you are installing.

Make sure the cables are aligned correctly and inserted completely or the slide bar will not close.

Slide the lock bar closed completely, and use the T-10 TORX driver tool to tighten the screws clockwise 
(torque 10 in-lbs, 1.13 Newton meters (Nm)).

Clamp bar maximum torque 15 in-lbs (1.70 Nm).
