To make longer cable lengths than those shown in the above table, use over 4-pair shielded CPEV cable. (For
the cable connection, see p. 3-70.)
The relationship of the CPEV cable conductor diameter to the maximum cable distance is as follows:

• When the VX-3000DS or the VX-3150DS is operating on AC power
The maximum distance of power cable between the RM-300X or RM-500 and the VX-3000DS or the VX-
3150DS is as follows.
The following table shows the maximum cable distance when STP Category 5 straight cable (with RJ45
connectors) is used.
