Connecting to the Network

Making the UTP Connections

Caution: To prevent damage to the equipment, do not connect the PoE supported ports (1 through 48) to segments running between buildings. Keep connections to equipment within the building.

Precaución: Para evitar que el equipo se dañe, no conecte los puertos PoE

(1 a 48) a segmentos que vayan de un edificio a otro. Mantenga las conexiones de los equipos dentro del edificio.

To connect and verify UTP cable connections to RJ45 ports (1 through 48), refer to Figure 3‐4 and proceed as follows:

1.Ensure that the device connected to the other end of the segment is powered ON.

2.Insert the RJ45 connector on the twisted pair segment into the appropriate RJ45 port connector.

3.Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing amber, blinking green, or solid green). If the RX LED is OFF and the TX (Transmit) LED is not blinking amber, perform the following steps until it is on:

Note: If the RX and TX LEDs of a port do not indicate a link and the end-point device is a PD, you may have a port without 48 Vdc to operate the PD. To check the PoE Port Status, refer to “Verifying PoE Port Status” on page 3-19.

a.To view the receive and transmit activity on a group of segments, press the GROUP SELECT button for less than one second (see Figure 3‐4) to step to the group of interest (Groups 1 through 4).
