Unpacking and Installing Your ELS100-16TX

To connect the LCM:

1.Connect your ASCII terminal or terminal emulator to the out- of-band management RS232C port on the front panel of the ELS100-16TX using the standard RJ-45 twisted pair cable shipped with the unit. (Only three wires are necessary: Receive Data, Transmit Data and Ground.)

2.Set the terminal to 9600 baud, 8N1: 8 data bits, 1 stop bit, no parity, and no ﬂow control.

3.Press the Enter key several times. If the ELS100-16TX and terminal are operational, LCM responds with the ELS100-16TX > prompt.

4.LCM is now ready to use.

Refer to Section 1.6, Local Console Manager, for a general overview of LCM and the command syntax. LCM commands for conﬁguring, monitoring, and managing the ELS100-16TX are provided in the chapters dealing with those topics.

2.6 CONNECTING TO THE NETWORK

This section provides the procedures for connecting UTP and multimode ﬁber optic segments from the network or other devices to the ELS100-16TX.

The ELS100-16TX is conﬁgured with 16 IEEE 802.3 10/100 BASE-T autosensing RJ45 Ethernet ports. The ELS100-16TX provides the option of substituting RJ45 ports 15 and 16 (either or both) with two EPIM ports. These ports accept the EPIM-100FX, which have SC style MMF connectors.

Refer to Section 2.6.1 to make UTP connections.

Refer to Section 2.6.2 to make a ﬁber optic connection to an EPIM-100FX.
