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.
The following is a recommended procedure for surface mounting the analog
clock:
1.
Determine the clock mounting location.
2.
Mark the Mounting Point location.
Note that the Mounting Point is located 2½” (6.35 cm) below the top of the clock
rim.
3.
Refer to Figure 2 to install the junction box for the data cable (if required)
centered 2 ½” (5 cm) to the right of the Mounting Point.
4.
Insert a flat-head fastener suitable for the wall surface at the marked point
and tighten.
5.
Withdraw the fastener until there is a ¼” (or a little more than ½ cm) gap
between the mounting surface and the back of the fastener head.
6.
Insert the data cable into the jack located at the back of the OnTime Clock.
7.
Position the keyhole slot located on the rear of the clock over the fastener
head.
8.
Pull the clock slightly downward until the unit is seated securely.
