7.1.2. AU Connections

Prior to attempting the AU connections, read Section 4 thoroughly.

The AU has eight optical ports, designated by eight silk-screened images: AU1, AU2, OP1/AU, OP2, OP3,

OP4, OP5 and OP6. The ports OP1~OP6 all have the same functionality, providing connections to lower

level EU-Es. Insert the optical module into any one of the OP1~OP6 ports, then insert the tail of the optical

fiber into the optical module and connect the other end to the lower level EU-E. After the AU and EU-E are

connected and powered on, the optical interface indicator LED will turn green, which indicates that the

devices are synchronized. If the optical indicator LED stays red, check whether the connection direction of

the optical fiber is correct and the optical module is inserted tightly.

The AU1 and AU2 optical ports are for connecting to the slave AU. Before connecting a Slave AU to Master

AU, access to Slave AU independently (see Section 3.2 for instructions how to access the WebOMT of

Slave AU). Ensure the Device Type of this AU is Slave AU and then plug optical fiber module.

Note: The connection between the Master AU and the Slave AU can only be from the OP1/AU port on the

Slave AU to the AU1 (or AU2) port on the Master AU; other optical ports are invalid for Master-Slave AU

connections.

7.1.3. EU-E Connections

Prior to attempting the EU-E connections, read Section 5 thoroughly.

The EU-E has 2 optical ports, 12 GE ports and 12 10GE ports. The optical SLAVE port should be connected

to Master AU or an upper level EU-E and the optical MASTER port should be connected in a cascading

manner to a lower level EU-E in a daisy chain. (Refer to the networking definition of a daisy chain.) The

10GE1~12 ports have the same functionality and are all used for connections to NPRUs. After an EU-E is

connected to a upper level device and powered on, the device are synchronized when the optical indicator

LED turns green.

Each EU-E has 12 GE ports, GE1~GE12, which support 12 LAN signals. Each GE port corresponds to a

specific 10GE port, for example, port GE1 corresponds to port 10GE1 and port GE12 corresponds to port

10GE12.

7.1.4. NPRU Connections

Prior to attempting the NPRU connections, read Section 6 thoroughly.

The NPRU has 10GE and GE ports. The 10GE port is connected to an upper level EU-E with CAT-6 STP

whose length shall be up to 100 meters and GE port is connected to a PC or monitor with CAT-5. After the

NPRU has been connected to the upper EU-E and powered on, the device are synchronized when the

optical indicator LED turns green.
