[. . . ] rate, indicating an out-of-power budget, thus, this port will not deliver power. The power distribution method is based on "First Come, First Served" logic. Sometimes, connected operating PDs significantly increase or suddenly raise their power requirements. If the required power exceeds the available power, the Power over Ethernet Midspan starts to turn off ports in accordance with their priority (the first turned off port is the lower priority port) until the total power is once again under the maximum limit. Default priority is establishid by port number: the higher the port number is, the lower priority it gets.

No. : 06-6860-056 PD-6548 Table 2-1: Power Status Indications Indicator Color Off AC Symptom Internal power supply unit is unplugged or faulty Remarks Internal power supply voltage is too low. Green Orange Indicates AC power Internal power supply voltage input active is within tolerance. Internal problem alarm Built in Test (BIT) failed. Table 2-2: Port Status Indications Port LED Color Off Port Load Conditions Non-active load or unplugged port. Power to the port is not connected or, if previously connected ­disconnected at the moment. No DC voltage is present on the spare pairs. Green Green blinks at a 1 sec. Total aggregated power exceeds pre-defined power budget (400w by default). Power over Ethernet Solutions 13 Cat. No. : 06-6860-056 PD-6548 2. 4 Connectors The Midspan's front panel includes a Console port (RJ-45 connector) that supports two communication types: 1. Standard DTE Ethernet connector only at the web managable version of the midspan. This connector is a standard 10/100BaseTX port that is used for remote management of the device (see Table 2-3). For connecting the port to a switch output, use a straight-through ethernet cable. for connecting the port directly to a PC port, use a crossed-over ethernet cable. Table 2-3: Console Ethernet Connector Pin # 1 2 3 4 5 6 7 8 Label TX+ TXRX+ spare spare RXspare spare Description Plus signal, transmit from midspan Minus signal, transmit from midspan Plus signal, received to midspan Minus signal, received to midspan 2. Proprietary RS232 connector for console purposes: The user may connect a terminal and perform software loading via the connector, using the console cable included in the supplied kit. The console port is set to 38, 400-baud, 8 data bits, no parity and 1 stop bit. The RJ-45 connector of the cable should be connected to the Midspan's console terminal and the D-type 9 pin should be connected to the PC. Pin connections for the D-type connector are as follows: Power over Ethernet Solutions 14 Cat.

[. . . ] Remove and re-apply power to the device and check the indicators during power up sequence as described in Para. The Midspan did not detect a PD and therefore the port is not enabled. Verify that you are using a standard Category 5/5e/6, straight-wired cable, with four pairs. If an external power splitter is in use, replace it with a known-good splitter. [. . . ]
