K PowerDsine PowerDsine 6500 Series 2 About the Power over Ethernet Midspan PowerDsine's family of Power over Ethernet Midspans, series 3500 & 6500, injects power over data-carrying Ethernet cabling. The PD6506/6512/6524 Midspans, support 6, 12 and 24 ports respectively in a 10/100BaseTx Ethernet network, over TIA/EIA-568 Category 5/5e/6 cabling. DC operating power, for data terminal units, is fed over unused pairs of the cabling (7/8 and 4/5). The Power over Ethernet Midspan normally powers devices that are `Power over Ethernet Enabled'or are equipped to receive power over Ethernet. These devices are called Powered Devices (PDs). Devices that are not can receive power over Ethernet, may require an external power adapter in order to be powered. Power over Ethernet Midspan main features: Safe and reliable power over existing Ethernet infrastructure Eliminates the need for AC outlets, local UPS & AC/DC adapters near PDs Remote Management using Web control and/or SNMPv3 Highest level of Network Security Safe solution that protects network infrastructure Standards compliant. 2. 1 Power Management When establishing a network, the total power required by the PDs may exceed the total power available from the Midspan. The built-in Power Management feature does not allow total power output to exceed maximum power available (refer to the Technical Specifications). When total power available is near maximum, attempts to connect an additional PD to a free port cause the corresponding LED of the port to blink orange, indicating an out-of-power state. Power distribution is based on "first come, first served" logic. Sometimes, connected and operating PDs significantly increase or suddenly raise their power requirements. If the power required exceeds the power available, the Midspan starts turning off ports, starting from the last port down, until the total power is once again under the maximum PowerDsine 7 The Power over Ethernet Pioneers PowerDsine 6500 Series available limit. 2. 2 10/100BASE-TX Ports Definition 2. 2. 1 Data Input Ports The Midspan has 6, 12 or 24 x 10/100Base-T Data In ports, located on the PoE rear panel (Figure 2-1), configured in a non-crossover manner (straight-wired). These ports are located on the PoE's rear panel designed to carry Ethernet data only (Tx/Rx) over the standard 2-wire pairs (pins 1/2 and 3/6) and are typically connected to an existing Ethernet switch. 2. 2. 2 Data & Power Output Ports The Midspan has 6, 12 or 24 x 10/100Base-T Data & Power Out ports, located on the front panel (Figure 2-2). These ports are configured in a non-crossover manner (straight-wired) and are designed to carry Ethernet data over the standard 2-wire pairs (pins 1/2 and 3/6) and DC power over the spare pairs (pins 4/5 and 7/8). Each output port corresponds to an opposite input port located on the PoE rear panel. . The Power over Ethernet Midspan is not a repeater. As such, the maximum distance from the Ethernet switch must not exceed 100 meters (328 ft). As specified in the IEEE 802. 3 standard, the Power over Ethernet Midspan is guaranteed to work up to this distance.

Refer to Table 2-1 and Table 2-2 for status information during operation. 2. 3. 1 Primary Power Indicators The "Main" LED on the front panel provides the Power over Ethernet Midspan power status. When the Main indicator is illuminated in green, the Midspan receives AC power. [. . . ] Remove and re-apply power to the device and check the indicators during power up sequence. . 1. The Midspan did not detect a PD and therefore the port is not enabled. A port indicator is not lit and the corresponding PD 2. Verify that the PD is designed for Power over Ethernet operation.
