Overview
– 24 –
devices such as IP phones and wireless access points, which translates into
greater network availability.
For each attached PoE-compliant device, the switch automatically senses the
load and dynamically supplies the required power. The switch delivers power to a
device using the wire pairs in UTP or STP cable. Any RJ-45 port on the switch can
provide up to 30 W of power, but only two ports can deliver 30 W simultaneously
to attached devices without exceeding the switch power budget.
DESCRIPTION OF HARDWARE
10/100/1000BASE-T PORTS
The switch contains 8 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or
full duplex, and 1000 Mbps full duplex. Because all ports on this switch support
automatic MDI/MDI-X operation, you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. (See
"1000BASE-T Cable Requirements" on page 49.)
Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10, 100, or 1000 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.
SFP TRANSCIEVER SLOTS
The Small Form Factor Pluggable (SFP) transceiver slots are independent ports.
The following table shows a list of transceiver types that have been tested with
the switch. For an updated list of vendors supplying these transceivers, contact
your local dealer. For information on the recommended standards for fiber optic
cabling, see "Fiber Optic SFP Devices" on page 47.
