 Baseline Switch 2426 PWR Plus is a 

versatile, easy-to-use configurable Power-over-Ethernet 
(PoE) Switch. It is ideal for users who want the 
high-speed performance of 10/100 switching with the 
added functionality of Gigabit fiber links, but do not 
need sophisticated management capabilities. The Switch 
is shipped ready for use. No configuration is necessary.

The Switch has 24 shielded RJ-45, 10/100 Mbps 
auto-negotiating ports and 2 Gigabit combo ports 
(which comprised of a RJ-45 port and a Small Form 
Factor Pluggable (SFP) transceiver slot) on the front 
panel for easy, flexible connection to fiber-based Gigabit 
media. 

All ports on the Switch can autosense both medium 
dependent interface (MDI) and medium dependent 
interface crossover (MDIX) connections. This allows you 
to connect network devices to each port using either a 
normal straight-through TP (twisted pair) cable or a 
‘crossover’ TP cable. 

Any port can therefore be used to connect to another 
switch port, server, or workstation without additional 
configuration.

Each 10/100 Mbps port automatically determines the 
speed and duplex mode of the connected equipment 
and provides a suitable switched connection. The 
10/100 Mbps ports can operate in either half-duplex or 
full-duplex mode.
