6.2.3 914-EX Power
Power to the 914-EX card is provided via the expansion connector J9. Power input connect J2
should not be used
during normal operation with the 914-EX. It can optionally be used for standalone operation during firmware updates
or configuration.
If the 914-EX is to be self-powered, this is accomplished via connector J2, Molex P/N 09-75-2024. The mating plug
is Molex P/N 26-03-4020 with crimps P/N 08-52-0113. The pinout is provided in the table and figure below.
Figure 6-16: Factory Power Input Connector Location
The recommended input voltage range is 4.5 VDC to 13.0 VDC (typically +5 VDC regulated). Nominal power
consumption is 3.5 W, increasing to 4.2 W at 60
o
C ambient temperature with both ports linked at 1000 BASE-T.
Power leads should be AWG 18
– 20.
The onboard surface mount fuse, F1, is rated to 2A and is not intended to be field replaceable. If the power fuse
is blown, the card should be evaluated for damage by the factory or trained service personnel prior to any repair.
