Description of Hardware
10/100BASE-T Ports
The PoE switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All ports
support automatic MDI/MDI-X operation, so you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs.
(See “10/100BASE-TX Pin Assignments” on page B-1.)
Each of these ports support auto-negotiation, so the optimum transmission mode (half
or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a
device connected to one of these ports does not support auto-negotiation, the
communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.
1000BASE-T/SFP Ports
These are combination Gigabit RJ-45 ports with alternate Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is
installed in a slot, the associated RJ-45 port is disabled.
The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so you can
use straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. (See “1000BASE-T Pin Assignments” on page B-4.)
Note: The 1000BASE-T RJ-45 ports do not support PoE capability.
Port and System Status LED Indicators
The switch base unit also includes a display panel for key system and port indications
that simplify installation and network troubleshooting. The LED indicators, which are
located on the front panel for easy viewing, are shown below and described in the
following tables.
