3. 10/100/1000BASE-TX Ports Definition
The following sections detail PD9000G ports, and their functions.
3.1 Data Input Ports
Midspan has 6, 12, or 24 10/100/1000Base-T Data In ports, located on PoE front panel ( Figure 3-1 ), configured in a
non-crossover manner (straight-wired).
These ports are designed to carry Ethernet data only (Tx/Rx) over:
• Standard 4-wire pairs (pins 1/2, 3/6, 4/5, and 7/8) (1000Base-T)
• 2-wire pairs (pins 1/2 and 3/6) (10/100Base-T)
3.2 Data and Power Output Ports
Midspan has 6, 12, or 24 10/100/1000Base-T Data & Power Out ports, located on the front panel as shown in the
following figure. These ports are configured in a non-crossover manner (straight-wired) and carry Ethernet data over:
• Standard 4-wire pairs (pins 1/2, 3/6, 4/5, and 7/8) (1000Base-T)
• 2-wire pairs (pins 1/2 and 3/6) (10/100Base-T)
• PD-90xxG series carry DC power over 2-wire pairs (pins 4/5 and 7/8)
Note: Power over Ethernet Midspan is not a repeater. Therefore, the maximum distance from Ethernet switch must
not exceed 100 meters (328 ft). Power over Ethernet Midspan is guaranteed to work only within this distance, as
specified in IEEE 802.3at standard.

3.3 Indicators
A set of indicators displays the status of the PoE Midspan and its ports. For more information about the status
information during operation, see
Table 3-1 and Table 3-2 .
3.3.1 Power Indicator LED
Power Indicator LED on the front panel displays power status of PoE Midspan. When the LED is illuminated in green,
it indicates that the Midspan is receiving AC power. For more information, see
Table 3-1 .
3.3.2 Port Indications
The following sections detail PD-90XXG port indicators.
3.3.2.1 PD-90xxG Midspan Series
One uni-color indicator (green) per port displays port status:
• Green indicates terminal unit (PD) has been identified as Power over Ethernet Enabled , it is active and
receiving power.
• Blinking green indicates port does not supply power and is inactive.
