Inova Solutions OnTime 4-Digit Digital Clocks, Installation And User Manual

Page: 9 / 42

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
