Hardware components of the Ethernet Routing Switch 2500 Series
27
The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex
mode operation.
The 10BASE-T/100BASE-TX RJ-45 switch ports can connect to 10 Mb/s or
100 Mb/s Ethernet segments or nodes.
ATTENTION
Use only Category 5 copper Unshielded Twisted Pair (UTP) cable connections
when connecting 10BASE-T/100BASE-TX ports.
Auto-MDI/MDI-X
The 10/100BASE-TX port connectors support auto-MDI/MDI-X.
Typical MDI-X ports connect over straight-through cables to the Network
Interface Card (NIC) in a node or server, similar to a conventional Ethernet
repeater hub. However, with the auto-MDI/MDI-X feature, you can still use
straight-through cables while connecting to an Ethernet hub or switch.
The auto-MDI/MDI-X feature is dependent on the autonegotiation feature.
If autonegotiation is enabled on a port, the auto-MDI/MDI-X feature is
automatically enabled on the port as well. If autonegotiation is disabled on a
port, then the port operates as a standard MDI-X port.
Power over Ethernet on Ethernet Routing Switch 2526T-PWR
and 2550T-PWR
The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide IEEE
802.3af-compliant power over the PoE-labeled front-panel RJ-45 ports. The
switches provide power discovery and power management on each port
basis. You can use the PoE ports to provide power to network appliances,
such as IP Phones, wireless access points, and video devices.
You can enable or disable power to individual ports. For information about
configuring PoE, see
"Power over Ethernet for the Ethernet Routing Switch
2526T-PWR and 2550T-PWR" (page 157)
.
