8 Port IP Video Extender Over UTP
With Built-In Gigabit PoE Switch with EtherStretch
ER8500U
The ER8500U is another component of NITEK cutting edge EtherStretch line. Our EtherStretch solution
allows for the utilization of existing cable infrastructure (coax or UTP) to transmit data from IP cameras and
other network devices along with power (PoE & PoE+) to operate these networked devices over the given
wire media well over the 100m/328ft networking distance limitation.
The ER8500U is a Ethernet & PoE extending rack mounted eight (8) port power sourcing receiver unit with
built-in gigabit switching capabilities. The unit requires very little installation time and absolutely no set up or
configuration. The ER8500U and associated ET1500U transmitters (up to 8) can quickly turn ordinary CAT5e/
CAT6 UTP cables into a series of high speed network communication and PoE pathways. The ER8500U is a
fully functional PoE+ network switch with a 802.3AT power output on each of the eight (8) network ports and
can operate with any standard Ethernet device up to 100m. Additionally, when used with the ET1500U trans-
mitters the system allows for cable runs of 600m/1,960ft supplying both a network connection and PoE+ pow-
er.
The ER8500U is completely transparent to the network thus requiring no IP and MAC addressing. Simply con-
nect your network devices to the transmitter LAN ports along with the existing cables to the receiver and the
system quickly begins communicating. LED indicators show the status and data speed of network communi-
cations along with PoE power confirmation.
NITEK EtherStretch ER8500U reliably extends network communications to overcome cable distance limita-
tions offering connectivity to devices in locations traditional networking does not allow. The ER8500U is ideal
for retro-fitting existing installations or for use in lieu of fiber for long distance transmission with the additional
PoE over the link capability. The rack mounted unit is robustly constructed of molded steel casing with appro-
priate built in cooling and ventilation.

Installation Considerations
Wire and Cable Recommendations: The ER8500U is designed for use with up to sixteen ANSI/TIA/EIA defined
CAT5e or CAT6 Unshielded Twisted Pair (UTP) cables. These UTP cables shall be able to accommodate TCP/IP
data operating speeds of 10/100 Mbps and gigabit rates. The RJ45 termination pin out schemes shall be in accord-
ance with the 568A or 568B standard. The quality of which must be consistent with any reasonably serviceable ca-
ble condition. That is free from damage as in cuts, breaks, or cracks to the outer covering and insulated shielding
which may compromise the signal conductivity of the cables.
For more specific information regarding wire types, gauges, and proper installation techniques please call Tech
Support at 1-[phone].
Ethernet & PoE: The ER8500U is designed to receive up to 100Mbps (per port) of Ethernet TCP/IP data and
transmit up to 2 Gigabits of aggregate LAN traffic. Additionally, the ER16500U provides per port sourcing PoE to
operate the ET1500U transmitters and any attached network devices while supporting 15.4W (802.3af) to 25.4W
(802.3at) powering schemes at a maximum distance of 600 meter / 2000 feet. Before considering this solution be
sure that the cable involved do not exceed the recommended maximum length. If the cable length value is indeter-
minate at the time of installation, we recommend the use of an Ohm meter which measures electrical resistance to
determine unknown cable distances.

The ER16500U can be rack mounted, wall mounted or used as desk top unit. Use the included mounting ears in the
front or back of the unit depending on your needs. The mounting ears can also be turned to the bottom of the unit
for wall mounting if needed. When mounting the unit, be sure to follow these guide lines.
a. Operating Ambient - Do not install the unit in an assembly where the ambient temperature could exceed
52°C (125°F). NOTE: the ambient temperature in a closed or multi-unit rack assembly could greatly exceed
the ambient temperature outside that assembly.
b. Air-Flow – Leave space on the sides of the unit for airflow into the cooling fans and some space on top of the
unit for air to exit the unit. Adequate air flow is required for safe operation.
c. Mechanical Loading – The mounting ears were designed for two ears to support one unit. Other
configurations, such as mounting other equipment directly on top of the unit or using only one mounting ear,
could cause a hazardous condition due to uneven or excessive mechanical loading.

Installation & Setup
Installment Topology
Up to eight (8) NITEK ET1500U’s interface with an assortment of network peripherals providing both power (PoE)
and Ethernet data connectivity over up to eight (8) UTP “Link” cables at the maximum distance of 1,960ft/600m.
The 1Gigabit LAN port on the ER8500U provides congestion-free connectivity to network switches and other LAN
devices for data sorting, storage, and processing. Each port of the ER8500U outputs a max of 25.5W (PoE+)
power and 100Mbps of data bandwidth throughput.
Equipment Requirements & Mounting: The process for employing the ER16500U is rather quick and simple. A common
topology involves up to sixteen (16) existing UTP cables (up to but not exceeding 600m/1,960ft), up to sixteen (16) ET1500U
transmitters, up to sixteen (16) IP cameras or other peripheral network devices (referred to as the Power Device or PD), and
the rack mounted ER16500U (which can be referred to as the NITEK Power Sourcing Equipment/PSE). The ER16500U
NITEK PSE is both 802.3af and 802.3at compliant. That is it produces 15.4W 48VDC @ 350mA of 802.3af as well as 25.4W
54VDC @ 600mA of 802.3at PoE+ power for proper attached device operation.
The method for facilitating Ethernet communication and PoE flow over CAT5e/CAT6 UTP cable starts with connecting the
ER8500U NITEK PSE with up to eight (8) UTP “link” cables via the RJ45 connectors. The CAT5e/CAT6 cables interface
with the IP camera or other PD via the ET1500U transmitters. The IP camera / PD establish connectivity to ET1500U via
RJ45 jacks and a CAT5e/CAT6 patch cords. The ER8500U powers itself and all attached devices within in this local net-
work/system. The IP data from the PD is transmitted over each individual UTP “link” cable through the ET1500U to the rack
mounted ER16500U in either the IDF or MDF. The aggregate PD data is transmitted to the greater LAN or WAN via a giga-
bit LAN ports labeled and located on the front of the NITEK PSE. Also commonly done is to use the LAN port to chain two or
more ER8500U units together via a separate network switch. This will provide a way of bring greater numbers of cameras
into a single NIC of a NVR unit. The ER8500U has special LED indicators to inform you if there are network loops. If the
Trouble LED is flashing slowly it will indicate that the network has a loop in it and data is cascading. It is recommending to
remove the LAN jack if this occurs and try to locate the physical loop if this problem occur.
Upon power up the devices will undergo initialization and auto-configuration processes (see LED Indicator chart on pg.#7)
which may take a number of seconds (time variations are device/installation/topology parameter dependent) to complete
before PoE and Ethernet communication commences. For optimal performance referring to the PoE/distance chart and ad-
hering to the IP camera/PD operational specifications is recommended. If issues arise during the installation process please
see the “Trouble Shooting Tips” section. You may also contact our web based live tech support at: www.nitek.net or call 1-
[phone] in order to speak with one of our engineers directly.
The diagram below shows a common network topology.

At the camera location securely mount the transmitter.
Find the Link cable from the head-end and make sure it is properly terminated. Connect Link cable to the “Link Port”
of the transmitter. If the head-end unit is powered up it will sense the connection to the transmitter and turn on the
power. This will be indicated by the green POWER LED on the “Network Port”. After about 15 to 30 seconds the
orange 10/100Mb LED on the “Link Port” will turn-on to tell you that the system is connected. An Ethernet device
does not need to be connected for the transmitter to communicate with the head-end.
Finally, connect an Ethernet device to the transmitters “Network Port”. If the device requires PoE power, the POE
OUT, green LED on the “Link Port” will turn on followed by the LINK STATUS LED on the “Network Port”. The IP
camera or other Ethernet device should now be ready to operate. Continue installing the remaining transmitters as
needed.

In some cases the PoE device connected to the transmitter needs more power than can be supported over a long
cable run. You can usually identify these cases by watching the POWER LED of the transmitter, located on the
“Network Port”. If the power light cycles ON for less then 1 second and then is off for 3 or 4 seconds when the PoE
device is connected, but it turns ON and operates normally without a PoE device connected, this would indicate you
are having a current limit problem.
You should first check the power requirements of the PoE device. Also check the length of the Link cable from head
-end to transmitter. The POE POWER CHART on the previous page will indicate the maximum power available for
your length of cable.
If the needed level of power is not available for the length of cable, used alternate options are available. One meth-
od is to directly power the transmitter with a 48VDC power supply as shown below (Nitek# PS48). When powered
directly from a 48VDC supply the transmitter can deliver full 802.3AT power regardless of the cable length plus an
additional length of up to 100 meters of network cable.
