Enabling PoE support on Endura NET5401T and NET5402T video encoders.

Issue

Enabling PoE support on Endura NET5401T and NET5402T video encoders.

Product Line

Pelco Transmission & Power

Environment

  • NET5401T
  • NET5402T
  • NET5404T supports only 24V

Cause

By default, the Power over Ethernet (PoE) feature is disabled on the NET5400T Series video encoder. You must enable PoE manually if you intend to attach a PoE-capable power supply to the encoder.

Resolution

The NET5400T Series encoder includes three base models: NET5401T and NET5402T. Before enabling PoE, please note the following important information:

  1. By design, only the 1 and 2-channel encoders support Power over Ethernet (PoE) and Power over Ethernet Plus (PoE+) respectively.
  2. By default, the 1 and 2-channel encoders are shipped from the factory with PoE support disabled. The user must manually enable PoE support using the instructional guide Enabling POE on the NET5400T (C4671M) before attaching a PoE-capable power supply to the encoder.
  3. Note the different power requirement for the 1 and 2-channel, especially if both models are to share the same power source such as a PoE Ethernet switch. To power the NET5402T, the power source must conform to 802.3at-2009 standard which specifies a maximum load power of up to 25 W. IEEE 802.3af-2003 standard specifies a maximum load power of 15.40 W, but only 12.95 W is available after counting cable losses. For complete power specification for NET5400T Series encoders, reference the A&E documentation Endura NET5400T Intelligent Video Encoder A&E.
  4. If the encoders are to be racked using the RK5200PS-5U chassis, DO NOT enable the PoE support feature because the circuit board will be damaged when connected to both power sources and cause the units to fail.

Enabling PoE on the NET5400T Series

WARNING: You must use a power supply that provides 2 kV ground isolation when PoE is enabled on the encoder. Failure to do so can cause the unit to fail if it is connected to a sheared power supply, such as the RK5200PS-5U

1. Remove the four screws from the side panels.

2. Lift up that back of the lid, and then slide it off the chassis.

3. Remove the PoE switch, rotate it, and insert it over all 20 pins. Make sure that all 20 pins are covered.

4. Slide the lid onto the chassis, and then secure it in place with the screws you removed in step 1.
