A valid system software image for the port adapter has been downloaded successfully.
•
The system recognizes the PA-2FEISL or a VIP2 with a PA-2FEISL.
If any of the above conditions are not met, or if the initialization fails for other reasons, the enabled LED
does not go on.
lists port LED colors and indications.
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.
shows the RJ-45 cable connectors. Cisco does not supply Category 5 UTP RJ-45 cables; these
cables are available commercially. lists the pinouts and signals for the 2FEISL-TX RJ-45 connectors.
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.
