Reach PoE Tester Manual V1.4

Page 8

NOTE: with high power loads, the DC balance of the patch cables used is important to

avoid DC saturation of the Ethernet transformers. DC Balance (DC resistance per side

of the power carrying pair) should be within 3%. The standard patch cable

specifications of Cat 5, 5e, and 6 do not specify DC balance.
