This document covers installing the IE 3000 65 W DC-input power supply (PWR-IE65W-PC-DC). This DC-input power supply is designed to power the Cisco IEM-3000-4PC and IEM-3000-4PC-4TC Power over Ethernet (PoE) expansion modules with the following caveats:
- The 65 W DC-input power supply can support only one PoE expansion module.
- Each power supply is capable of supporting a maximum of four PoE ports or two PoE+ ports on the PoE expansion module.
Note
For complete list of translated safety warnings and compliance information, see the Regulatory Compliance and Safety Information for the Cisco IE3000 for the Cisco IE 3000 Switch on cisco.com

Safety
Warning statements in the document use the following conventions:
Statement 1071—Warning Definition
Tools and Consumables Required
The following tools and consumables are required to install the power supply:
Before You Begin
The DC-input power supply does not contain a fan. The power supply relies on the ambient air for cooling. Make sure that the temperature surrounding the power supply does not exceed 140°F (60°C).
Note When the switch, PoE expansion modules, and the DC-input power supply are installed in an industrial enclosure, the temperature within the enclosure is often greater than normal room temperature outside the enclosure. Temperature measurements should be made within the enclosure.
Installation Warning and Caution Statements
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of:
140°F (60°C) Statement 1047
Airflow around the switch must be unrestricted. To prevent the switch from overheating, there must be the following minimum clearances:
– Top and bottom: 1.0 in. (25.4 mm)
– Sides: 1.0 in. (25.4 mm)
– Front: 1.0 in. (25.4 mm)
Contact your Cisco Technical Assistance Centre (TAC) if tighter spacings are required.
Installing the Power Supply
To mount the DC-input power supply to a DIN rail, follow these steps:
Step 1 Remove the power supply from the shipping packaging.
Step 2 Position the rear panel of the power supply directly in front of the DIN rail, making sure that the DIN rail fits in the space between the two hooks near the top of the power supply and the spring-loaded latch near the bottom of the power supply chassis.
Step 3 Holding the bottom of the power supply chassis away from the DIN rail, place the two hooks on the back of the power supply over the top of the DIN rail. (See Figure 2.)
Step 4 Pivot the power supply toward the DIN rail so that the spring-loaded latch snaps into place on the underside of the DIN rail.
Figure 2 Installing the Power Supply on the DIN Rail
Connecting the DC-Input Power Supply
You need to connect the DC-input power supply first to the expansion module and then to source DC.
Note The DC-input power supply can support only one PoE expansion module.
Note The DC-input power supply can support up to a maximum of four PoE ports or two PoE+ ports. If you intend to operate all four PoE ports on the expansion module in PoE+ mode, you can not use the power supply; you must use site source DC power.
If used in a hazardous location provision be made external to the apparatus, to prevent the rated voltage being exceeded by transient disturbance of more than 40 percent.
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045
Warning Use twisted-pair supply wires suitable for 86°F (30°C) above surrounding ambient temperature outside the enclosure. Statement 1067
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
Connecting the Power Supply to the PoE Expansion Module
To connect the DC-input power supply to the PoE expansion module, follow these steps:
Step 1 Measure a length of twisted-pair copper wire long enough to connect the power supply’s DC OUT terminal block to the PoE expansion module’s Input DC terminal block.
For DC connections from the power supply to the PoE expansion module, use 18-AWG twisted-pair copper wire, such as Belden part number 9344 or the appropriate type, wire size, and color-code for your country.
Step 2 Using a wire-stripping tool, strip both ends of the twisted pair wires to 0.25 in. (6.3 mm) ± 0.02 in. (0.5 mm). Do not strip more than 0.27 in. (6.8 mm) of insulation from the wires.
Step 3 Insert the twisted-pair wire leads into the power supply’s DC OUT terminal block positive (+) and negative (-) connections. Verify that only insulated wire extends from the connectors. (See Figure 3.)
Step 4 Secure the twisted-pair leads to the terminal block connectors using the torque ratchet screwdriver to tighten the terminal block screws.
Note Do not overtighten the terminal block screws. The recommended tightening torque is 2.2 in-lb (0.25 N-m).
Figure 3 Connecting the Power Supply’s DC Out Leads
Step 5 Connect the other end of the twisted-pair wire leads to the Input DC terminal block connectors on the PoE expansion module making sure that only insulated wire extends beyond the terminal block.
Verify that the positive (+) wire goes from the positive (+) connector on the power supply to the positive (+) connector on the expansion module and that the negative (-) wire goes from the negative (-) connector on the power supply to the negative (-) connector on the expansion module.
Step 6 Secure the twisted-pair leads to the terminal block connectors using the torque ratchet screwdriver to tighten the expansion module terminal block screws.
Note Do not overtighten the terminal block screws. The recommended tightening torque is 2.2 in-lb (0.25 N-m).
Connecting Source DC to the Power Supply
Note Use copper conductors only.
To connect the power supply to source DC, follow these steps:
Step 1 Verify that power is off to the DC circuit that you are going to attach to the DC-input power supply. As an added precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on the circuit.
Step 2 Measure and cut a length of twisted-pair copper wire long enough to connect the power supply to the DC source power.
For connections from the power supply to the source DC, use 18-AWG twisted-pair copper wire, such as Belden part number 9344 or the appropriate type, wire size, and color-code for your country.
Step 3 Using a wire-stripping tool, strip the insulation from both ends of the ground wire and both ends of the twisted pair wires to 0.25 in. (6.3 mm) ± 0.02 in. (0.5 mm). Do not strip more than 0.27 in. (6.8 mm) of insulation from the wires.
Step 4 Insert the twisted-pair wire leads into the DC IN terminal block positive (+) and negative (-) connections. Ensure that only insulated wire extends from the connectors. See Figure 4.
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the power and relay connector. Statement 122
Step 5 Secure the twisted-pair leads to the terminal block connectors using the torque ratchet screwdriver to tighten the expansion module terminal block screws.
Note Do not overtighten the terminal block screws. The recommended tightening torque is 2.2 in-lb (0.25 N-m).
Figure 4 DC Source Cable Connections on the Power supply
Step 6 Connect the other end of the twisted-pair wire leads into the source DC positive (+) and negative (-) connectors.
Step 7 Remove the safety flags from the source DC circuit breaker and set the circuit breaker to the on position.
There is no power switch on the DC-input power supply. As soon as source DC is turned on, the power supply is energized and DC voltage is fed to the expansion module. The LED on the power supply front panel should be lit green indicating that the unit is operating normally. The LED is off when the unit is not powered on or is not operating normally.
Hazardous Locations Installation
This section provides a set of warnings and cautions governing the installation of the DC-input power supply in hazardous locations. You should read and understand the following warnings and cautions prior to installing the power supply in a hazardous location.
