The Inova OnTime Clock brings all the advantages of Power over Ethernet (PoE)
technology to the marketplace in a real-time synchronized system of clocks.
PoE is an exciting and relatively new technology that allows devices to get both
power and data over standard network cabling. It is the same technology that
powers Voice over Internet Protocol (VoIP) phones.
Delivering both data and power over one set of wires simplifies installation,
saves space, and eliminates the need for electrical outlets at the clock mounting
locations. Additionally, the option of centralized Uninterrupted Power Supply
(UPS) backup allows PoE devices to continue running even in the event of a
power failure.
Note: The local area network must support IEEE 802.3af PoE for the OnTime
clocks to operate.

Before installing any display, you should:
Obtain all necessary permissions from facilities managers or property
owners.
Develop a LAN diagram showing the desired location of each display
unit.
Plan the Power over Ethernet (PoE) power solution.
Select a mounting method for the clock.
Acquire tools and materials including assorted screwdrivers, power drill,
and other materials necessary to ensure that mounting brackets are
installed in compliance with building codes and restrictions.
When the clock shipment arrives, inspect all packing boxes for damage. Unpack
all clocks and inspect them so that you can report any damage to Inova
Solutions.
The OnTime clocks require connection to PoE enabled network equipment that
can source power in compliance with IEEE 802.3af. PoE power is commonly
used to power devices such as wireless Access Points and IP telephones; it is
usually injected into the LAN using either PoE enabled Ethernet switches or Mid
Span power injectors. Consult with your IT Group to make sure that the
required PoE equipment is in place.
Single port PoE power injectors are the best means of powering PoE devices for a
demonstration system or a small scale deployment. Inova Solutions offers a
single port PoE injector for sale to support these systems (see Figure 1). Refer to
Inova OnTime™ Online Store for more information on this part.
A power injector is typically installed in the communications room, and passes
Ethernet communications through while also injecting power in accordance with
the IEEE 802.3af standard. The 48 VDC power is only supplied to devices that
request it through a handshake mechanism, so normal Ethernet devices are not

damaged if connected to a standard PoE port. Note that a power injector
requires a connection to AC power, and may be connected to a battery backed
uninterruptable power supply (UPS).
Figure 1: PoE Cabling Plan
Sites that are already equipped with PoE enabled network equipment are most
likely already compatible with the OnTime clock. The OnTime clock will
automatically request and receive power from a PoE enabled switch that
conforms to the IEEE 802.3af standard.
If the site plan calls for a significant number of clocks to be powered from a
single piece of network equipment, it may be useful to verify that that piece of
equipment can deliver the necessary power. Some PoE enabled switches cannot
deliver the full IEEE 802.3af power of 15.4 Watts per port or may require certain
power options to do so. Refer to the specifications in Table 1 for the actual power
consumption of all of the units and to the manual for your particular PoE
enabled power sourcing equipment.

Sites that are not currently equipped with PoE enabled network equipment are
typically best served by Midspan Power Injectors. The Midspan Power Injector
is a multi-port rack mounted device that looks a lot like an Ethernet Switch.
Typically it is installed in the rack near the existing Ethernet switch, and any
ports that require PoE service are routed through the Midspan Power Injector.
These units are typically available in 6 port, 12 port, 24 port, or 48 port
configurations. The Inova OnTime™ Online Store offers a single port PoE
injector for sale to support demonstration systems. Note that Midspan Power
Injectors can also be configured for battery backup.
The OnTime clocks require connection to a PoE enabled LAN. PoE power is
usually injected into the LAN using either PoE enabled Ethernet switches or Mid
Span power injectors. Consult with your IT Group to make sure that the
required PoE equipment is in place.
