 Baseline Switch 

2816/2824-SFP Plus. It also identifies the contents of the 
Switch package and helps you get to know the physical 
features of the device.

The 3Com Baseline Switch 2816-SFP/2824-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 links, but do not need sophisticated 
management capabilities. The Switch is shipped ready 
for use. No configuration is necessary. 

The Switch has 16 (2816-SFP) or 24 (2824-SFP) shielded 
RJ-45, 10/100/1000 Mbps auto-negotiating ports and 
four Small Form Factor Pluggable (SFP) transceiver slots 
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. 
The 1000BASE-T ports also support automatic 
10/100/1000 Mbps speed detection.

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.

The four SFP ports support fiber Gigabit Ethernet 
short-wave (SX) and long-wave (LX) SFP transceivers in
