1000BASE-T/SFP Ports

These are combination Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. If an SFP transceiver (purchased separately) is
installed in a slot and has a valid link on the port, 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-3.)

Port and System Status LEDs

The ES3526XA includes a display panel for key system and port indications that
simplify installation and network troubleshooting. The LEDs, which are located on
the front panel for easy viewing, are shown below and described in the following
tables.
