The switches are designed to be connected to 10, 100, or 1000 Mbps
network cards in PCs and servers, as well as to other switches and hubs. It
may also be connected to remote devices using optional 1000BASE-SX,
1000BASE-LX, 1000BASE-LH, or 100BASE-FX SFP transceivers.
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. Use Category 5, 5e, or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and
Category 3 or better for 10BASE-T connections.
The ES-3026P switch automatically detects a PoE-compliant device by its
authenticated PoE signature and senses its required load before turning on
DC power to the port. This detection mechanism prevents damage to other
network equipment that is not PoE compliant.
Power-over-Ethernet connections work with all existing Category 3,

4, 5, 5e, or 6 network cabling, including patch cables and patch-panels,
outlets, and other connecting hardware, without requiring modification.
The switch delivers power to a device using the wire pairs in UTP or STP
cable (RJ-45 pins 1, 2, 3, and 6). The switch can provide up to 30 W of
power continuously on each of the first six ports. If a device tries to draw
more than 30 W from a port, an overload condition occurs and the port
disables the power. The rest of the ES-3026P's 24 10/100 Mbps ports
(ports 7 ~ 24) support the normal PoE (802.3af), which can provide up to
15.4 W of power.
The switch controls the power and data on a port independently. Power can
be requested from a device that already has a data link to the switch. Also,
the switch can supply power to a device even if the port's data connection
has been disabled. The power on a port is continuously monitored by the
switch and it will be turned off as soon as a device connection is removed.
