Using a Splitter with the 20-Port and 10-Port
Mid-Span Power Hubs
Some products require a BL-89705ENT or BL-89712ENT splitter (sold separately) that
splits power and data into separate cables, and converts the ~48 VDC into 5.0 VDC or
12.0 VDC for input power. To ensure compliance with class A requirements, use category
5, 5e, or 6 shielded twisted pair straight-through cables.
Figure 2-3 shows a typical configuration for the Enterasys 20-port Mid-Span Power Hub
operating with a splitter.
