 3 Baseline 10/100 Switch 48-Port 

10BASE-T/100BASE-TX plus 2-Port Gigabit is a versatile, easy-to-use 
unmanaged switch. It is ideal for users who want the high-speed per-
formance of 10/100 switching with the added functionality of two 
Gigabit links, but do not need sophisticated management capabilities. 
This Baseline Switch is shipped ready for use; no configuration is nec-
essary.

The Baseline Switch has 48 shielded RJ-45, 10/100 Mbps 
auto-negotiating ports and two shielded RJ-45, 10/100/1000BASE-T 
ports on the front panel. Each port automatically determines the 
speed and duplex mode of the connected equipment and provides a 
suitable switched connection. Each port also supports automatic 
MDI/MDI-X detection.

The Baseline Switch is suited for office use where it can be free 
standing, or rack mounted (in a wiring closet or equipment room).

The Baseline Switch comes with:

„

One power cord

„

Four self-adhesive rubber pads

„

One mounting kit

The Baseline Switch provides high performance switched connections 
to 10 Mbps and 100 Mbps hubs, servers and workstations that need 
a dedicated switched link and two 10/100/1000 BASE-T ports that 
can connect to other 10/100/1000 BASE-T ports or servers and 
workstations.
