POE-48iD
Power-Over-Ethernet Midspan
POWER OVER ETHERNET MIDSPAN
Power Supply / Inserter
The POE-48iD is an advanced 802.3af compliant device with Midspan Intelligent Detection. The
device does not turn on power until it detects a valid Power-Over-Ethernet (POE) signature from
the devices attached downstream on the Ethernet cable. This protects against damage to non-
compliant equipment which may be connected to the Ethernet cable. Because of this intelligent
detection, only an 802.3af compliant device can be powered with the POE-48iD. Because of its 48
V inserter, the installer doesn’t need to worry about voltage drops due to cable length. Typically
in 100 MB networks, the maximum allowable CAT5 cable run is about 100 meters. This is not a
limitation of the POE equipment, but rather a limitation of the Ethernet standards. The POE-48iD
is not a proprietary unit. It will function with any equipment which is fully compliant with the
IEEE 802.3af POE standards. Note: The equipment being powered must be fully 802.3af
compliant in order for the power supply to be able to sense the devices signature and apply
power. Power is supplied on Ethernet pins 4/5 (V+) and 7/8 (GND).
Using POE to power remote devices has several advantages including:
• The power supply can be centrally located, where it can be attached to an
uninterruptible power supply.
• The user has the ability to easily power on reset the attached equipment
from a remote location.
• There is no need to run additional power cabling to the device, as power can
be supplied over the CAT5 Ethernet cable.
