ABOUT THIS MANUAL
ADC’s Midspan Power over Ethernet (PoE) Controller eliminates the need to run power for IP telephones, wireless LAN Access Points, webcams and other Powered Data Terminal Equipment
(PDTE) at the end of the LAN line, without modifing existing Ethernet infrastructure. Installers need to run only a single Ethernet Cat 5, 5E, or 6 cable to carry both power and data to each device. This allows greater flexibility in locating of network devices and significantly decreases installation costs in many cases. ADC’s Midspan Power over Ethernet (PoE) Controller is
IEEE802.3af compliant. ADC’s Midspan Power over Ethernet (PoE) Controller is designed for use within a building not for use with a MAN (Metropolitan Area Network). To assure continued operation in the unlikely chance that a power supply should fail the Midspan Power over Ethernet
(PoE) Controller is available with an optional redundant power supply.

1 INTRODUCTION
ADC’s PoE is not a data hub or switch. ADC’s PoE adds 48VDC to the pairs (4/5 and 7/8) of the
Ethernet data path that is then fed to power devices. ADC’s PoE is designed for use with standard
10Base-T, 100Base-TX, or 1000Base-T Ethernet over 8-wire Cat 5, 5E, or 6 cable. ADC’s PoE
Midspan Controller is available with 8-, 16-, or 24-ports. An optional CPU is available for use when
SNMP is required. CPU card is hot-swappable allowing card to be inserted into a powered chassis.
ADC’s PoE normally powers devices that are enabled for power over LAN or are equipped to receive power over Ethernet. These devices are called Powered Devices (PD) or Powered Data Terminal
Equipment (PDTE). Devices not equipped to receive power over Ethernet must have local power.
1.1
Power over Ethernet Midspan Controller Features
• Supply power to remote Ethernet terminals
• Eliminates the need for AC power at remote Ethernet terminals
• Universal power input (100-240 VAC 50/60 Hz)
• 15.4 Watts (48 VDC) available to each port
• Optional SNMP management
• Redundant power supply option (Hot swappable)
• Up to five chassis may be daisy-chained together using a single IP address for SNMP communications
• Independent overload and short-circuit protection on each channel
• Individual port status indicators
• Standard 19-inch rack mounting (Optional extender brackets for 23-inch rack mounting)
• Replaceable AC-DC power supplies
1.2
Power over Ethernet Front View Detail
Data and power output ports are the upper ones as shown in Figure 1 . Each PoE has 8, 16, or 24
data and power ports configured as Media Dependent Interface (MDI) non-crossover. These ports are designed to carry 10Base-T or 100Base-TX Ethernet data over the standard 2-wire pairs (RJ-45 pins 1/2 and 3/6) or 1000Base-T Ethernet data over all four pairs. DC power is carried over wire pairs (RJ-45 pins 4/5 and 7/8).
Data input is through the lower ports as shown in
Figure 1 . All ports are designed to carry
10Base-T and 100Base-TX Ethernet data (TX/RX) over the standard 2-wire pairs (RJ-45 pins 1/2 and 3/6) or 1000Base-T Ethernet data over all four pairs.
The Com IN port provides two functions. First it is used as a Console port for configuration of the CPU-SNMP linecard. Second it is used as the Com IN port for chassis daisy-chaining. This connector is an industry standard DB-9 receptacle. Com IN port may be used to obtain port status information when there is no CPU SNMP linecard installed.
Com OUT port is an industry standard DB-9 plug used for chassis daisy-chaining only. Any combination of up to five PoE Chassis may be controlled using one IP address and one CPU.

2 INSTALLING THE POWER OVER ETHERNET CHASSIS
2.1
Unpacking and Inspection
Unpack and inspect the various components as follows:
1. Inspect the exterior of the shipping container(s) for evidence of rough handling that may have damaged the components in the container.
2. Unpack each container while carefully checking the contents for damage and verify with the packing slip.
3. If damage is found or parts are missing, file a claim with the commercial carrier and notify
ADC Customer Service. Save the damaged cartons for inspection by the carrier.
4. Refer to Section 12, Customer Information and Assistance if you need to contact ADC.
5. Save all shipping containers for use if the equipment requires shipment at a future date.
The following procedures provide the necessary instructions for installing and wiring a Power over Ethernet Chassis in an equipment rack.
2.2
Rack Installation
Mounting brackets and mounting screws are shipped loose. Mounting brackets are positioned for 19-inch rack installation (Optional extender brackets available for 23-inch rack mounting.)
Adjustable mounting brackets allow chassis to be installed flush with the equipment rack face or at a depth of two-inches. Do not obstruct ventilation vents on the chassis.
Caution: When mounting the PoE chassis in the rack make sure mechanical loading is even to
avoid a hazardous condition, such as loading heavy equipment in the rack unevenly. The rack should safely support the combined weight of all equipment installed in it.
Warning: To prevent electrical shock, never install chassis in a wet location or during a lightning
storm. Before making any connections verify that input power source is off (switch in the OFF position or AC plug removed).
If PoE chassis is installed in a closed or multi-rack assembly, operating temperature of the rack environment may be greater than the ambient temperature. Install PoE chassis in an environment that is compatible with the maximum rated ambient temperature. See
Caution: Installation of the PoE chassis in a rack without sufficient air flow may result in
unsafe operation.
Note: Install PoE chassis in the equipment rack so that forced air by the chassis does not compromise safe operation.
This procedure provides instructions for installing the chassis in an EIA or WECO 19 or 23inch equipment rack. Check the work order to determine the chassis location in the rack and the mounting, flush or recessed.

5 COMMUNICATION/DAISY-CHAIN PORTS
Com IN communications port on the front panel may be connected to a terminal or PC for local communications to the chassis. When more than one chassis are connected together all Com IN ports (chassis) after the first one become Com IN ports used to support the daisy-chain.
5.1
Com IN Port
Figure 1 shows the Com IN port position on the chassis. Com IN port is a DB-9 receptacle style
connector providing an RS-232 DCE interface for local communications. Pins two and three are used for data communications and pins one, six, and nine are used for chassis daisy chaining.
When connecting a terminal to the COM IN port for local communications, use a DB9 straight through cable. When this port is connected to a terminal it is called a Console (CON) port. If the chassis is number two, three, four, or five in a daisy-chain this port is referred to as Com IN.
This port does not support a modem. This port is used for local access to the chassis and is used to set the initial communication parameters. Shielded cable is recommended and the maximum cable length is 25 feet. A 1:1 cable is required to connect this port to the DTE com port of a PC.
Pin out information is shown in Table 7 and Figure 6 .

9 OPERATION
These instructions describe the user interface found on the COM IN serial port of the ADC PoE
Midspan Controller with legacy support. Interface provides status information for all Ethernet ports and power supplies as well as alerts for any status changes. Legacy PoE equipment may require power pins to be reversed (crossed) to provide power over the span. ADC PoE Midspan Controller may be set to support IEEE-802.3af or legacy equipment through one or more ports.

Start Up
The on-board PoE micro-controller features a minimum command-line interface over the serial
DB-9 receptacle COM IN port. Chassis status may be viewed by connecting a computer or terminal to this port. Connect a VT-100-compatible host computer to the COM IN port.
Set up communications with the chassis. A communications software program or terminal is required to communicate with PoE chassis. Use a DB9 straight through cable to connect the
COM IN port to the host terminal or computer. Use a straight through cable, when connecting a terminal to the COM IN port for local communications. Communication parameters must be set to 9600 baud, 8 Data bits, 1 stop bits, no parity and no flow control.
LED's indicate port and power status, see Section 1.3, LEDS for descriptions.
Upon boot-up, the unit briefly sets all Ethernet port LEDs to yellow then green and displays the following over the COM IN port (See
Type <ENTER> to show status
'?' to show usage
‘TL’ to test LED’s
'Xnn' to toggle power pins for Ethernet port n (01-24)

Figure 10. Unit Status
The first block of information briefly describes the user commands available over the COM IN port:
• Type <ENTER> to refresh the midspan unit status,
• Typing a question mark ‘?’ displays Help Menu,
• The ‘TL’ command repeats the LEDs test performed upon boot-up (all port LEDs yellow then green) to verify all port LEDs,
• The ‘Xnn’ command allows crossing of the power-over-Ethernet power pins of a port to support legacy equipment requiring this setting.
The second block of information shows the midspan firmware version.
The third block (starting at ‘Cat#’) shows:
• The midspan inventory information (catalog number, part number and serial number),
• For each power supply, its status and inventory information.

ADCP-92-055 • Issue 6 • January 2006
The fourth block of information shows PoE port status:
• Port numbers from 1 to 24,
• Crossover of the power-over-Ethernet power pins indicated by an ‘X’ for a port,
• Port status: ‘D’ for disable, blank when no device is attached to the port, ‘L’ for a detected legacy PoE device at the port, the 802.3af power classification number (from 0 to 3) for
802.3af-compliant PoE devices detected at a port, or one of the following lowercase characters for error conditions causing the port to be left unpowered:
‘-’: non-PoE device attached,
‘b’: power budget exceeded,
‘e’: external voltage source applied to the PoE device,
‘f’: succession of overloads and underloads detected,
‘g’: discharged load detected,
‘h’: hardware fault,
‘o’: overload,
‘s’: short condition,
‘t’: over-temperature,
‘u’: underload,
‘?’ or ‘!’: unknown state for the port.
• Power status: a ‘P’ is displayed for powered ports (with a corresponding green LED), while an asterisk ‘*’ is shown for ports with one of the error conditions listed above.
The last block of information shows the number of ports powered, the ports wattage consumption, and midspan unit uptime.
On the midspan unit status example shown
• Both power supplies are inserted and functioning correctly,
• PoE port 12 has its power pins crossed over,
• Ports 2 and 19 detected and are powering legacy PoE devices,
• Port 24 detected an 802.3af class 2 device and is powering it,
• 3 out of 24 ports are powered and consume 8 watts,
• The midspan unit has been up 7 hours, 54 minutes and 10 seconds.
Power pins for port 12 were crossed with an ‘X12’ command issued over the COM IN port. The
‘Xnn’ command (where nn is the port number from 01 to 24) toggles the crossover setting of the
PoE port power pins. Hence entering this command twice in a row for a particular port will place the power pins back to the original setting. Every time the crossover setting is changed for a port, it is saved in the permanent PoE configuration of the midspan unit and does not need to be entered again if the chassis is powered down.

The ADC PoE midspan unit also sends alerts over the COM IN port upon PoE port status changes, such as:
- Port 24: ON [802.3af]
- Port 02: ON [legacy]
- Port 13: OFF
802.3af compliant device found and powered on port 24,
Legacy PoE device found and powered on port 2,
PoE device removed from port 13.
The ADC PoE midspan unit sends alerts over the COM IN port upon power supplies status changes, such as:
- Unit: ** Power supply #1 A/C FAILURE !!
- Unit: ** Power supply #1 A/C restored
A/C feed failure for supply #1,
A/C feed restored for supply #1.
The on-board PoE micro-controller controls and monitors only the local unit. It does not provide control or status for other midspan units that may be daisy-chained to it. In addition:
• In a daisy-chain environment, only the first unit will feature this command-line (other units down in the daisy-chain have the command-line disabled). Use the optional CPU card in a daisy-chain environment to provide status and control for all daisy-chained units.
• When optional CPU card is plugged in, it takes over the serial COM IN port from the on-board micro-controller. The command line interface is disabled. Refer to the CPU command manual.
10 TROUBLESHOOTING
This section helps you locate problems related to the PoE setup and functionality.
Troubleshooting provides a problem and possible resolutions to assist in locating minor operating problems. If the provided resolutions do not solve your problem, call ADC for further assistance.
If you encounter problems, make sure:
• Power is applied to the chassis.
• An input Ethernet cable is connected to the Data port.
• An output Ethernet cable is connected to the Data & Power port.
• The input and output cable pairs are attached to corresponding ports.
Table 10. Troubleshooting
PROBLEM
PoE is plugged into a main AC outlet, but does not power up.
PoE is plugged in and running, but fan is not working.
RESOLUTION
Verify that a correct and functional AC power cord is used, including a good solid ground connection.
Verify that AC outlet is supplying power (test with another device) and that voltage is between 100VAC and 240VAC (50Hz/60Hz).
Reconnect PoE to AC outlet and verify the LEDs power up sequence.
See
Verify all fan openings in chassis are clear of any obstructions.
If fan is not working, there may be an internal power supply fault.
Replace power supply.

PROBLEM
PoE operates, but AC LED is off.
PoE has powered up and ON
LED is red.
Power supply is operating and rear LED is amber.
RESOLUTION
If internal fan is working, there is a possible internal circuitry fault.
If fans are not working, there may be an internal power supply fault.
Replace power supply.
Check self-test sequence. If LEDs light in the correct sequence, PoE is fully operational.
If problem remains following self-test sequence, PoE self-test detected an internal fault. Contact ADC.
Power supply has exceeded the maximum operating temperature and will shut down.
• Verify all fan openings in chassis are clear of any obstructions.
• If fan is not working, there may be an internal power supply fault.
• If internal fan is working (that is, air flows in to the chassis or can be heard), there is a possible internal circuitry fault.
Replace power supply.
Port LED on one port is not lit and the corresponding remote device does not operate.
PoE did not detect a connected remote device, therefore port is not providing power. Verify that:
• Remote device is Power Over LAN enabled.
• Verify that you are using a standard UTP Category 5, 5E, or 6 cable, including all 8 wires (4 pairs).
• If an external splitter is in use, replace it with a new splitter. Discard faulty splitter.
• Remote device is connected to the Data & Power port (upper RJ-45 connector).
In addition, try to:
• Re-connect the same remote device to a different port on the same unit. If it works, there is probably a faulty port or RJ-45 connection.
• Bypass the long twisted pair cable and move remote device closer to
PoE and connect to one of the ports using a short cable. If this works, most likely there is a faulty connection or short on the long cable, or a bad RJ-45 connection in the line.
Try powering it up again and verify a correct power-up LED sequence.

PROBLEM
Remote device operates, but there is no data link.
One of the ports is powering a remote device without turning
Port LED on.
Is it safe to keep PoE running while the rear LED is Amber?
RESOLUTION
Verify that:
• Port LED on PoE front panel is lit continuously.
• Data and Data & Power ports correspond.
• Verify that you are using a standard UTP Category 5, 5E, or 6 cable, including all 8 wires (4 pairs), and is 100m or less in length between switch and remote device.
• PoE is connected to a switch or hub with a good RJ-45 patch cord connection.
In addition, try to:
• Bypass the long twisted pair cable and move remote device closer to
PoE and connect to one of the ports using a short cable. If this works, most likely there is a faulty connection or short on the long cable, or a bad RJ-45 connection along the line.
• Connect a different remote device to the port. If this works and link is established, there is probably a faulty data link in the remote device.
• Re-connect remote device to a different Data & Power port and remember to move the Data port of the switch or hub accordingly. If this works, there is probably a faulty Data & Power or Data port in the PoE or a bad RJ-45 connection.
Re-connect remote device to a different Data & Power port. If the
LED turns on, there is a fault in the previous output port (probably a faulty LED).
Yes, this condition is safe for a short period of time.
11 SNMP – WEB MANAGEMENT
Use of optional CPU linecard provides a 10/100Base-T Ethernet connection through a RJ-45 jack.
