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-2.)
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-5.)
Note:
The 1000BASE-T RJ-45 ports do not support PoE capability.
