Symmetricom ND-CLK User Manual page 7

AC Versions:
AC models of the ND-CLK are supplied with an IEC power cord
POE Versions:
Power Over Ethernet (POE) models will require an IEEE 802.3af compliant POE
injector, or switch with +48VDC output on spare pairs of the network cable conductor 4
& 5 with corresponding 48 VDC returns on pins 7 & 8, or by sharing the data pins and
their returns.
[Important Note: the ND-CLK with an installed POE (Power Over Ethernet) option, will
obtain its power directly from a POE powered source using the spare wires of a standard
network cable with RJ45 connector for input power. The POE source must be a fully
compliant IEEE 802.3af PSE operating at +48VDC. POE sources not IEEE 802.3af
compliant might damage the clock and void the warranty. ]
