Power-over-Ethernet Capability

The Switch provides 24 front panel RJ-45 ports that
support the IEEE 802.3af Power-over-Ethernet (PoE)
standard. Any 802.3af compliant device attached to a
port can directly draw power from the switch over the
Ethernet cable without requiring its own separate power
source. This capability gives network administrators
centralized power control for devices such as IP phones
and wireless access points, which translates into greater
network availability.

Gigabit Combo Ports (RJ-45/SFP)

The 2 Gigabit combo ports support fiber Gigabit
Ethernet short-wave (SX) and long-wave (LX) SFP
transceivers in any combination. This offers you the
flexibility of using SFP transceivers to provide
connectivity between the Switch and a 1000 Mbps core
network.
When an SFP port is in operation, the corresponding
1000BASE-T port is disabled. The 1000 Mbps
connections can only operate in full duplex mode.
