10/100 Mbps ports can operate in either half-duplex or
full-duplex mode.

Power-over-Ethernet Capability

The Switch 2426-PWR Plus (3CBLSF26PWR) 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.
The Switch also supports a pre-standard implementation
of 802.3at, delivering up to 29.6 W per port (measured
at the PD, assuming 100 m Cat 5E cable connected
between the PD and the Switch 2426-PWR), subject to
the maximum power budget available.

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 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.
