Cisco IE 3000 Switch Hardware Installation Guide
Chapter 1 Overview
Front-Panel Description
100BASE-X SFP Port LEDs
The 100BASE-X SFP port LEDs are located on the two SFP expansion modules. The LED colors have
the same meanings as described in
Table 1-7 .
PoE Status LED
The PoE status LED on the front panel of the IEM-3000-4PC and the IEM-3000-4PC-4TC PoE
expansion modules displays the functionality and status of the PoE ports. The LED colors and meanings
are listed in
Table 1-9 .
10/100BASE-T PoE and Non-PoE Port LEDs
The 10/100BASE-T PoE and non-PoE port status LEDs on the front panel of the IEM-3000-4PC and the
IEM-3000-4PC-4TC PoE expansion modules display the functionality and status of the individual ports
on the expansion modules.
Table 1-9 PoE Status LED Colors and Meanings
Color PoE Status
Off PoE is off. If the powered device is receiving power from an AC power source,
the port LED is off even if the powered device is connected to the switch port.
Green PoE is on. The port LED is green only when the switch port is providing power.
Alternating green
and amber PoE is denied because providing power to the powered device will exceed the
power capacity of the expansion module.
Flashing amber PoE is off due to a fault.
Caution Noncompliant cabling or powered devices can cause a PoE port fault.
Use only standard-compliant cabling to connect Cisco prestandard IP
Phones and wireless access points or IEEE 802.3af-compliant devices.
You must remove any cable or device that causes a PoE fault.
Amber PoE for the port is disabled. (PoE is enabled by default.)
