ClearCube C/Port & MVX - Manual (Page 12)

2 • ClearCube C/Port Overview
C/Ports are connected via standard twisted-pair copper networking cables: CAT5, CAT5e,
CAT6, or CAT6e. Table 1 lists the distance limits for C/Port installations.
Note: When configuring an Admin Daisy Chain connecting 9 or more R4300 chassis, the
Admin C/Port must be located within 100 meters of the equipment rack if using CAT5
or CAT5e cable, or within 50 meters of the equipment rack if using CAT6e. When the
Admin Daisy Chain has 8 R4300 chassis or fewer, or is composed entirely of R4200
chassis, the standard distance lengths for C/Port cabling apply.

Cable Type Distance
CAT5 660 feet (200 meters)
CAT5e 660 feet (200 meters)
CAT6 * C7130: 330 feet (100 meters)
CAT6, CAT6e * * C7120 or earlier: 330 feet (100 meters)
C7130: 660 feet (200 meters)
* Cable certified for 45 nS / 100 meters delay skew or less.
