Section 1 – Introduction and Network Planning
Simplex PoE clocks operate with the IEEE standard for Power Over
Ethernet. The power for the clock is provided by a PoE injector or a
PoE Switch.
After you connect the clock, it will display the IP address associated
with the device.
The Simplex Ethernet clocks are linked together only in that they are
connected to the network and use the same time source. By updating
the clocks from the same time source, the clocks will remain accurate
to 200ms of that source.
There are four things that the clocks need from the network
1. A standard Ethernet connection using minimum CAT5 Cabling
minimum up to 300’ from the switch/router
2. Power over Ethernet using the IEEE 802.3AF standard (48v
DC). If the switch does not have this feature, it can be added
with single or multi port midspan injectors at the switch.
3. An IP address, fixed or provided by network DHCP service
4. SNTP (Simple Network Time Protocol) service from an internal
of external NTP server.
Section 2 contains System Integration information.
Sections 3, 4, and 5 cover the physical installation.
Section 6 contains instructions on how to configure your device using
Telnet commands.
