incoming connection.
This section describes the hardware installation of MS-PoE. Before
connecting any network device to the MS-PoE, read this section
carefully.
Before Installation
Before your installation, it is recommended that you check your network
environment. If there are any IEEE 802.3af devices that you need to
power, the MS-PoE can provide you a way to supply power for this
Ethernet device conveniently and easily. The MS-PoE works with an AC-
DC adapter (not supplied) with DC 48V input and injects this DC power
into the pin of the twisted pair cable (pair 4, 5 and pair 7, 8 for Fast
Ethernet).
