Introduction
Power over Ethernet (PoE) provides an accurate synchronized time source. PoE and Simple Network Time Protocol (SNTP) are
used to make installation and setup as simple as possible. All you need to do is connect the clock to a PoE enabled Local Area
Network (LAN) Ethernet drop.
PoE
Power over Ethernet (PoE) describes a system that passes electrical power, along with data, on Ethernet cabling. Power may
come from a power supply within a networking device such as a PoE switch or it may be injected into the Ethernet cable using a
midspan injector.
There are several advantages for using PoE. PoE eliminates the need to run AC power cables for certain devices. Instead, the
more cost effective category 5 or 6 cable is run for PoE devices. Also, since PoE is symmetrically distributed, the power source
may be determined after the cables are ran.
PoE clocks require connection to a PoE enabled LAN. In a typical installation, a PoE switch or a PoE injector would be used to
power your PoE clock.
Network
These Power over Ethernet Clocks are plug and play on networks with Dynamic Hosting Conguration Protocol (DHCP). A
NIST time server is used for the default time server but may be changed using the Network Clock Connect application or the
conguration web page.
The clocks may also be congured using static IP addresses.

Analog Clock Installation
Before installing, verify the network infrastructure with the Network Administrator. The Power over Ethernet (PoE) power solution
and Dynamic Host Conguration Protocol (DHCP) settings should be determined. The PoE clock locations and cabling routes
should also be determined prior to installation.
1. Apply power to the clock by connecting a CAT 5 (A) or higher Ethernet patch cable from a PoE switch (Fig. 1) or single
injector (Fig. 2) to the PoE receiver (F).
• PoE Switch: Check with the Network Administrator for infrastructure needs. This part is not supplied by American Time.
• PoE Injector (TMA200): This is an optional power source that may be purchased from American Time
2. The Status LED (B) will indicate the clocks status as follows:
• Flashing Orange: Acquiring an IP address using DHCP
• Flashing Red: Attempting SNTP sync
• Continuous Red: Failed SNTP sync
• Flashing Green: Received SNTP sync
• Continuous Green: Successful SNTP sync
Note: When a DHCP network is not present at initial start-up, the PoE clock will default to a random Static IP in the range of
169.254.1.0 to 169.254.254.255. The IP address may be reset by restoring the clock factory defaults by holding in the Default
Button (D) for 10 seconds and releasing. Both Status and Buzzer LEDs will ash for 5 seconds to conrm the defaults setting.
Please reference the DHCP troubleshooting section if you are experiencing DHCP issues.
3. The Buzzer LED (C) designates if the Buzzer is enabled. The Buzzer is an optional feature.
4. Place the clock on the wall using the keyhole hanger (E) on the back of the clock or the optional security bracket.
Note: If hanging your clock over an Ethernet jack, see Figure 3.

Digital Clock Installation
Before installing, verify the network infrastructure with the Network Administrator. The Power over Ethernet (PoE) power solution
and Dynamic Host Conguration Protocol (DHCP) settings should be determined. The PoE clock locations and cabling routes
should also be determined prior to installation.
1. Apply power to the clock by connecting a CAT 5 (A) or higher Ethernet patch cable from a PoE switch (Fig. 1) or single
injector (Fig. 2) to the rear panel of the PoE clock. The time should display in less than one minute.
• PoE Switch: Check with the Network Administrator for infrastructure needs. This part is not supplied by American Time.
• PoE Injector (TMA200): This is an optional power source that may be purchased from American Time
Note: When a DHCP network is not present at initial start-up, the PoE clock will default to a random Static IP in the range of
169.254.1.0 to 169.254.254.255.
If DHCP is enabled and the clock does not receive a DHCP IP or loses the IP, the following symptoms will occur:
–For 6 digit clocks, the seconds digits on the far right hand side of the clock will ash.
–For 4 digit clocks, the AM/PM indicators on the left side of the clock will ash
2. Upon startup the clock Firmware version and IP address will scroll across the display.
3. To adjust the Time Zone, push the Set button (B). Each button push will adjust the time by -1 hour. Example: If set to
Central Standard Time, push the button once for Mountain Standard Time.
4. Place the clock on the wall using the keyhole hanger (C) on the back of the clock. A mounting template is included with the
Quick Start Installation Guide.
Default Settings can be restored to the clock by:
1. Remove power to the clock for at least 2 seconds (disconnect the patch cable (A) from the back of the clock).
2. Hold down the Set button (B) on the back of the clock.
3. Apply power back to the clock (connect the powered patch cable to the clock) while continuing to hold down
the Set button.
4. 888 should scroll across the clock display.
5. Release the Set button.
Note: The IP address set to the clock can be checked by quickly pressing the Set button (B) twice. The Set button is located on
the back of the clock next to the patch cable (A) plug-in. Once pressed the clock IP address will scroll quickly across the display.
