10/100/1000BASE-T Ports

The switch contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full

duplex, or at 1000 Mbps, full duplex. Because all ports on the 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 Pin

Assignments” on page B-3.)

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.

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the

RJ-45 ports (ports 21~24). In its default configuration, if an SFP transceiver

(purchased separately) is installed in a slot and has a valid link on its port, the

associated RJ-45 port is disabled and cannot be used. The switch can also be

configured to force the use of an RJ-45 port or SFP slot, as required.
