No DC voltage is present on the spare pairs. 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.

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.

If an external power splitter is in use, replace it with a known-good splitter. Verify that for this link, you are using standard UTP/FTP Category 5 straight (non-crossover) cabling, with all four pairs. [. . . ]
