Cables, Connectors, and Pinouts
The two interface receptacles on the PA-2FEISL are a single RJ-45 connection (on the PA-2FEISL-TX)
or a SC-type optical-fiber connection (on the PA-2FEISL-FX). Each connection supports IEEE 802.3u
interfaces compliant with the 100BASE-X and 100BASE-T standards. The RJ-45 connection does not
require an external transceiver.

Tip
Ports labeled "Ethernet," "10BASE-T," "Token Ring," "Console," and "AUX" are safety extra-low
voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the
Basic Rate Interface (BRI) circuits are treated like telephone-network voltage, avoid connecting the
SELV circuit to the telephone network voltage circuits.

Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
