120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors
(all current-carrying conductors).

2.1.3 Cabling Rules to Remember
This section will help you understand the physical configuration restrictions for
the CrossFire 8720 Switch. In brief, you must remember the following rules when
planning to install the switch:
•
For shared-media LAN segments, acceptable distances are defined by the hub
or concentrator attached to the switch port.
•
Use cross-over cables for connecting between switch ports.
•
Use straight-through cables for connecting end-stations and switch ports.
•
If you create parallel paths directly between switches, be sure that you have
either use them as CrossLinks or verify that the Spanning Tree protocol is
enabled on that ports (see CrossLinks and Spanning Tree sections in the
Olicom CrossFire 8720 Fast Ethernet Layer 3 Switch Reference Guide). Note
that the Spanning Tree protocol is globally enabled by default.
