Nitek ER8400U - Manual (Page 4)

Installation & Setup
Equipment Requirements & Mounting: The process for installing the ER8400U is rather quick and easy. A com-
mon topology involves up to 8 new or existing UTP cables (not exceeding 2000ft / 600m), up to 8 ET1500U trans-
mitters and up to 8 IP cameras or other peripheral network devices. The wall mounted ER8400U, which can be re-
ferred to as the NITEK Power Sourcing Equipment (PSE), is compliant with both 802.3AF and 802.3AT devices. All
network connections should have RJ45 terminations and be in accordance with 568B pin out standards.
The method for facilitating Ethernet communication and PoE over UTP CAT5e/CAT6 cable starts with connecting
the ER8400U to a series of up to 8 UTP cables via its network ports. Each of the UTP cables interface with the IP
camera via the ET1500U transmitter, located at the camera end of the UTP cable. The IP camera establishes con-
nectivity to ET1500U transmitter via RJ5 jacks and a CAT5e/CAT6 patch cords. For cables shorter than 100 meters
the IP camera may be directly connected to the ER8400U. The ER8400U powers all attached devices within this
system. The Ethernet data from the camera is transmitted over each individual UTP cable through the ET1500U to
the wall mounted ER8400U in either the IDF or MDF. The aggregate Ethernet data is transmitted to the LAN port
via a built-in Layer 2 switch of the ER8400U. The Gigabit LAN port to ensure congestion-free throughput. An illus-
tration of this system is shown below in the “Installment Topology” diagram.
Upon power up the devices will undergo initialization and auto-configuration which may take a number of seconds
(time variations are device, installation and topology dependent) to complete before PoE and Ethernet communica-
tion commences. For optimal performance referring to the PoE Distance Chart later in this manual. Also adhering to
the IP camera operational specifications is recommended. If issues arise during the installation process please see
the “Trouble Shooting Tips” section later in this manual. You may also contact our web based live tech support at:
