ThinLAN Cable Requirements
The thin coaxial cables used with the HP AdvanceStack 10Base-T Hubs
must comply with the IEEE 802.3 Type 10Base2 requirements. Some
RG-58 A/U or RG-58 C/U cables meet these requirements.
The maximum length of a single thin coaxial cable segment is 185 meters.
The minimum length (for example, to connect adjacent hubs in a rack)
is 0.5 meter.
