4.1
Background Information
As shown in the following figure, Midspan is connected in series to an Ethernet switch/hub. Switch’s data output
terminals are connected to Midspan. Midspan delivers power over the spare twisted pairs (pins 7/8 and pins 4/5)
in PD-90XXG series of Category 5 cabling, without degrading data quality. Most installations require Midspan to be
rack-mounted.
