Ag8100
Power-Over-Ethernet Module
5. Functional Description
5.1. Inputs
The Ag8100 has a single input that can be connected to two external bridge rectifiers (see
Figure 1). This allows the Ag8100 to be compatible with equipment that use the different
power options, see Figure 3. It is important that the PSE does not apply power to both
bridge rectifiers at the same time (Refer to IEEE802.3af for more information).

5.2. PD Signature
When the Ag8100 is connected to the Cat 5e cable, it will automatically present a Powered
Device (PD) signature to the Power Sourcing Equipment (PSE) or Midspan Equipment,
when requested. The equipment will then recognise that a powered device is connected to
that line and supply power.
5.3. Isolation
The Ag8100 series conforms to the IEEE 802.3af standard except for the 1500V isolation,
which must be done externally. This is usually achieved without additional components, by
using a plastic insulated enclosure. Contact Silver Telecom for further details.
