Cisco IE 3000 Switch Hardware Installation Guide
Appendix B Installation In a Hazardous Environment
Connecting the Switch to the Power Converter
If an LED is off, the target device might not be turned on, there might be a cable problem, or there might
be a problem with the adapter installed in the target device. See
for
solutions to cabling problems.
Step 5
If necessary, reconfigure and restart the switch or target device.
Connecting to a PoE Port
Two expansion modules, the IEM-3000-4PC and the IEM-3000-4PC-4TC, provide 10/100BASE-T ports
with PoE capability. The IEM-3000-4PC expansion module provides four PoE ports, or the four ports
can be used as two PoE+ ports and two non-PoE ports. The IEM-3000-4PC-4TC expansion module
provides four PoE ports and four non-PoE ports or the eight ports can be used as two PoE+ ports and six
non-PoE ports. The PoE expansion modules each require a separate power supply to operate.
Note
Both the AC-input and the DC-input power supplies can support only two ports configured as PoE+
ports. If you want to operate all four PoE expansion module ports as PoE+, you must connect the
expansion module directly to the site’s source DC.
The expansion module PoE ports support either the IEEE 802.3af standard (PoE) which provides up to
15.4 W of power per port (4 ports total) or the IEEE 802.3at standard (PoE+) which provides up to 30 W
of power per port (2 ports total)
Connecting the Switch to the Power Converter
The Cisco IE 3000 switch can be used with an optional AC/DC power converter (PWR-IE3000-AC).
These sections describe the steps required to connect the switch to a power converter:

Warning
Explosion Hazard—Do not connect or disconnect wiring while the field-side power is on; an
electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure
that power is removed or that the area is nonhazardous before proceeding. Statement 1081
