OUTCLASS
Power over Ethernet class and power correction adapter
OUTCLASS is a simple passive adapter which corrects problems that
are frequently found with Power over Ethernet powered devices. It gives
low-power devices a Class 2 signature to solve power budgeting issues,
and can be used to modify or upgrade legacy devices to meet the
IEEE 802.3af standard.
IEEE 802.3af compliant PoE-powered devices must be capable of receiving their electrical power on either the"spare" or "data" pairs of their Cat 5 or similar network cable. However some devices will only receive sparepair
power. OUTCLASS routes the PoE power to the spare pairs of the network cable, allowing such devices
to be used with all IEEE-compliant PoE sources.
Some PoE-powered devices are not IEEE-compliant and require "always-on" or "dumb" PoE injection.
OUTCLASS gives these devices a PoE signature and power class (class 2 as standard),
allowing them to be
used safely with regular IEEE 802.3af/at switches and midspan injectors.
The adaptor may be used to make the following PoE devices Class 2 IEEE 802.3af compatible:
- Non-compliant devices, such as most 48V always-on implementations
- Partly-compliant devices, such as spare pair-only implementations
- IEEE compliant devices that do not implement power classification
