10/100 Mbps Ports
The ER52000 Hardened PoE Switch has 10/100 Mbps PoE ports (M12 D-Coding Female
4-Pin Connector) (see Figure 2-1). This port is auto-sensing, auto-MDIX 10/100 Mbps port.
When you insert a cable into a 10/100 Mbps PoE port, the Hardened PoE Switch:
Determines whether the cable is a straight-through or crossover cable.
Automatically ascertains the maximum speed (10 or 100 Mbps) and duplex mode (half- or
full-duplex) of the attached device.
After determining this information, the Hardened PoE Switch configures the 10/100 Mbps
PoE port automatically to enable communications with the attached device, without requiring
user intervention.
10/100/1000 Mbps Ports
The ER52000 Hardened PoE Switch has 10/100/1000 Mbps ports (M12 A-Coding Female

Preparing the Site
Before you install your Hardened PoE Switch, be sure your operating environment meets the
operating environment requirements in Table 2-2.
Table 2-2. Site Requirements
Characteristics
Requirements
Mounting
Desktop installations:
Wall-mount installations:
Provide a flat table or shelf surface.
Mount on a flat wall surface.
Access
Locate the Hardened PoE Switch in a position that lets you access the front panel Ethernet port,
view the front panel LEDs, and access the front panel power connector.
Power source
Provide a power source within 6 feet (1.8 meters) of the installation location. Power specifications
for the Hardened PoE Switch are shown in Appendix A.
Environmental
Temperature:
Install the Hardened PoE Switch in a dry area, with ambient temperature between -40 and 75ºC (-40
and 167ºF). Keep the Hardened PoE Switch away from heat sources such as direct sunlight, warm
air exhausts, hot-air vents, and heaters.
Operating humidity:
The installation location should have a maximum relative humidity of 95%, non-condensing.
Ventilation:
Do not restrict airflow by covering or obstructing the top and side panels of the Hardened PoE
Switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling.
Be sure there is adequate airflow in the room where you intend to install the Hardened PoE Switch.
Operating conditions:
Keep the Hardened PoE Switch at least 6 ft (1.83 m) away from nearest source of electromagnetic
noise, such as a photocopy machine.
Installing the Hardened PoE Switch
You can install your Hardened PoE Switch on a flat surface or Wall-mount with other
equipment.
If installing the Hardened PoE Switch on a desktop or shelf, allow sufficient ventilation
space between the device and the objects around it.
ER52000 Hardened PoE Switch Dimensions: 140mm (W) x 65.8mm (D) x 228mm (H)
(5.5”(W) x 2.59”(D) x 8.98”(H))
Connecting to the 10/100 Mbps Port
The front panel of the Hardened PoE Switch provides 10/100 Mbps ports (see “10/100 Mbps
Ports” on page 11). To prevent ESD damage, follow normal board and component handling
procedures.
To connect devices to the Hardened PoE Switch’s 10/100 Mbps port:
1. Insert one end of the cable into a 10/100 Mbps port.

15
ER52000 PoE Switch User Guide
2. Insert the other cable end into the Ethernet port of a computer, printer, network storage, or
other network device.
Connecting to the 10/100/1000 Mbps Port
The front panel of the Hardened PoE Switch provides 10/100/1000 Mbps ports (see
“10/100/1000 Mbps Ports” on page 11). To prevent ESD damage, follow normal board and
component handling procedures.
To connect devices to the Hardened PoE Switch’s 10/100/1000 Mbps port:
1. Insert one end of the cable into a 10/100/1000 Mbps port.
2. Insert the other cable end into the Ethernet port of a computer, printer, network storage, or
other network device.
Checking the Installation
Before you apply power:
Inspect the equipment thoroughly.
Verify that all cables are installed correctly.
Check cable routing to make sure cables are not damaged or create a safety hazard.
Be sure all equipment is mounted properly and securely.
Applying DC Power
1. Connect the female end (M12 S-Coding Female 4-Pin Connector) of the supplied DC
power cord to the power receptacle on the switch front panel.
2. Connect the other end to a grounded DC outlet.
When you apply power:
All green Link/Activity LEDs blink momentarily.
The green Power LED goes ON.
The Link/Activity LEDs for every port connected to a device flash, as the Hardened PoE
Switch conducts a brief Power On Self-Test (POST).
After the Hardened PoE Switch passes the POST, the Link/Activity LEDs for every port
connected to a device go ON. The Hardened PoE Switch is now functional and ready to pass
data.
If the Power LED is not ON, check that the power source is plugged in correctly and that the
power source is good.
