2. Using two data cables, connect both the data INPUT and data plus POE OUTPUT port of the Rajant
POE to an unmanaged switch.
3. Confirm that a data link is formed by inspecting the link lights on the Ethernet switch ports.
4. If the POE does not form a data link on both ports of the Ethernet data switch, replace the POE with
a new one.
Mitigation:
The recommended best practice is to only connect the Rajant POE IN port to a non-POE Ethernet switch.
Always connect the OUT port of a Rajant POE power supply to a BreadCrumb.
If only a POE switch is available, a data isolation transformer, such as L-COM BT-CAT6-P1 may be used
with Rajant POE power supplies. Connect the data port of the L-COM BT-CAT6-P1 to the POE switch port,
and connect the DATA+POWER port of the L-COM BT-CAT6-P1 to the Rajant POE power supply data input
port.

G.6 Installation Constraints for Rajant AC Powered Accessory POE Power Supplies
Product TSB Notice No.: 03-100163-001
TECH SERVICE BULLETIN
The approved use of Rajant supplied AC powered mid-span POE power supplies (as shown in the photo)
is limited to indoor, environmentally sheltered, non-damp locations that are isolated from shock or vi-
bration. The AC powered POE power supplies are not sealed for dust or water ingress, and are not intend-
ed to operate in an environment with condensing humidity. The construction of these POE models is not
ruggedized for exposure to mechanical shock or vibration.
Failure to observe the recommended installation restrictions may result in network outages and poor
network performance as POE device failure is likely, and will void the Rajant warranty of the accessory
POE. Damage to a Rajant BreadCrumb resulting from misuse of the AC powered POE may not be covered
by the BreadCrumb warranty.
Rajant Corporation does offer DC powered midspan POE models – namely the VHDC series – that are suit-
able for use in non-environmentally sheltered locations, such as vehicles and outdoor trailers. Verify the
ingress performance of the specific Rajant VHDC model on the product datasheet when selecting a mid-
span POE for a specific application.
