Feature 
Description 
Forwarding Modes
 
Store and Forward. 
Duplex Modes 
Half and full duplex on all front panel ports. 
Auto MDI/MDIX 
Supported on all ports. If fiber SFP transceivers are used, 
Auto MDIX is not supported. 
Flow Control 
In full duplex operation all ports are supported. 
Traffic Prioritization 
Four traffic queues per port. 
Ethernet Ports 
10/100 Mbps ports. 
Each 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. 
Gigabit Combo Ports 
The 2 Gigabit combo ports support fiber Gigabit Ethernet 
short-wave (SX) and long-wave (LX) SFP transceivers in 
any combination. This offers you 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. 
Mounting 
19-inch rack or standalone mounting. 
Fanless design (supported by 
Baseline Switch 2226-SFP Plus and 
Baseline Switch 2250-SFP Plus) 
Silent operation whether used in a rack or desktop situation.
PoE (Only supported by Baseline 
Switch 2426-PWR Plus) 
Each RJ-45 port supports the IEEE 802.3af 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.
