4.0 PORT AND CABLE ASSIGNMENTS
OTEB-CL-B series provide the following management ports:
RS-232 port: Suitable for examining OTEB-CL-B parameters and some system configuration.

Before connecting to one of the OTEB-CL-B series ports, please read the following
instructions and port connectivity requirements.
4.1 Management Port (RJ-45)
4.1.1 Port Description
The OTEB-CL-B series management port connector type is RJ-45.
Figure 4.1.1 RJ–45 Connector Plug and Socket
The Management port (RJ-45) can be connected to any device that uses a standard network
interface (e.g., a workstation, server, bridge or router). The RJ-45 connector can be
connected with similar network equipment (i.e. a network Hub). Use unshielded twisted-pair
(UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-Ohm Category 3, 4 or
5 cable for 10 Mbps connections or 100-Ohm Category 5 cable for 100 Mbps connections. The
maximum allowable cable length is 100 meters.
4.1.2 Pin assignment
When the network management cable (RJ-45 connector in each side) connects NMS PC and
OTEB-CL-B series directly, use a straight cable. See Figure 4.1.2.
