 Baseline Switch 2848-SFP Plus is a versatile, 

easy-to-use configurable Switch. It is ideal for users who 
want the high-speed performance of 10/100/1000 
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 44 shielded RJ-45, 10/100/1000 Mbps 
auto-negotiating ports and 4 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 10/100/1000 Mbps port automatically determines 
the speed and duplex mode of the connected 
equipment and provides a suitable switched connection. 

10/100 Mbps connections on these 1000BASE-T ports 
can operate in either half-duplex or full-duplex mode. 
1000 Mbps connections, on the other hand, only 
operate in full duplex mode.
