10/100/1000BASE-T Ports

The switches contain 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 these switches 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 the ES4625 and ports 45~48 in the ES4649). 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.

Stacking Ports

Each unit includes two stacking ports that provide a 40 Gbps high-speed serial stack

backplane connection. Up to eight 24-port or 48-port switches can be connected

together using optional stacking cables. Note that the 24-port and 48-port switches

can be mixed in the same stack. The Stack Master button enables one switch in the

stack to be selected as the Master.
