Out of Band Operation

Overview

In case the network goes down, or the SN0108 / SN0116 cannot be accessed with the usual browser based method for some other reason, the SN0108 / SN0116 can be reached via several additional Out of Band (OOB) methods. These include HyperTerminal, PPP, Telnet, and SSH. Each of these is described in the sections that follow.

HyperTerminal

HyperTerminal is a program included with Windows. It can be used to establish either a direct terminal connection, or an indirect (phone in) terminal connection. Both configurations are discussed below.

Direct HyperTerminal Connection

Setup:

To set up a direct HyperTerminal connection, do the following:

1.Use Ethernet cable and a DTE-to-DTE adapter to connect one of the SN0108 / SN0116's serial ports to a COM port on a PC (see the Installation section, pages 9 and 10).

Note: 1. See RJ-45 to Serial Adapters, page 78, for details on choosing the appropriate adapter. The usual choice for connecting to a PC is SA0141.

2.In the examples that follow we use COM1. If you use a different COM port, change the settings accordingly.

3.Be sure that the port you specify as the Console Port in the OOBC dialog box (see OOBC, page 22) matches the port that you are connecting the PC to. Change the setting, if necessary.

2.On your PC, run the HyperTerminal program:

Start → Programs → Accessories → Communications → HyperTerminal → Hypertrm.exe
