Instruction Manual
3.1.4 Power over Ethernet (PoE) Option
On models with the PoE feature (see Table 1), UTP Port A (the left port on the
front of the chassis) can be configured as a PoE Powered Device (PD). It
accepts power from a UTP-based Power Sourcing Equipment (PSE) and
supports the following PoE standards:
1. IEEE 802.3af-2003 Alternative A – power over data wires
2. IEEE 802.3af-2003 Alternative B – power over spare wires
3. Pre-Standard Cisco PoE – power over spare wires, with reversed polarity
(older Cisco switches)
The following table summarizes the UTP pinouts for each of the three
PoE Standards supported by this product.
