CHAPTER 5

COM PORT AND TELNET CONNECTIONS

This chapter provides information about the following items:

• Connecting and configuring a management terminal to the COM port of the 8H02-16 to access Local Management

• Connecting an Uninterruptible Power Supply (UPS) to the COM port of the 8H02-16 for UPS applications

• Establishing a Telnet connection

5.1

LOCAL MANAGEMENT TERMINAL CONNECTION

Connecting a terminal to access Local Management involves the following:

• Configuring the terminal so it can communicate with the 8H02-16

• Connecting the terminal to the COM port of the 8H02-16 with an RJ45 console cable

5.2

CONFIGURING THE TERMINAL

The following instructions outline how to configure your terminal to communicate with Local Management. Refer to your specific terminal manual for more instructions if necessary.

Use one of the following systems to access Local Management:

• A Digital Equipment Corporation VT100 terminal

• An IBM or compatible PC running a VT100 emulation program

To access the Setup Directory on a VT series terminal, press F3. Table 5-1

lists the required terminal setup for a VT series terminal.

Connecting a Management Terminal to the 8H02-16

5.3

CONNECTING A MANAGEMENT TERMINAL TO

THE 8H02-16

The 8H02-16 comes with a Console Cable Kit that provides a cable and

RJ45-to-DB9 adapter. The adapter allows the 8H02-16 RJ45 COM port to connect to an IBM or compatible PC running a VT series emulation software package. For detailed instructions regarding the connection of the console cable to the 8H02-16, refer to the instruction sheet provided in the Console Cable Kit.

Optional adapters are available to connect the 8H02-16 to Local

Management through a VT type terminal or a modem. Refer to the RJ45

Console Cable Kit Instruction Sheet for installation instructions and adapter specifications.

5.4

CONNECTING THE UPS TO THE 8H02-16

The following hardware is needed to connect the 8H02-16 to the UPS:

• An RJ45 console cable

• An RJ45 to DB9 adapter

To connect a cable from the UPS to the 8H02-16 COM port, perform the following steps:

1. Plug the RJ45 console cable into the 8H02-16 COM port.

2. Plug the other end of the console cable into the adapter and connect the adapter to the UPS.

With the cable connection complete and with a valid IP address entered into the 8H02-16 through Local Management (see Chapter 6) or through

Runtime IP Address Discovery (refer to Section 5.5, Runtime IP

Address Discovery), use one of the following management tools to

configure the 8H02-16 COM port for the UPS application:

• 8H02-16 Local Management through Telnet. The General

Configuration screen described in Chapter 6, Section 6.6.12, provides

the instructions to set up the COM port for the UPS application.

• Graphical user interfaces (GUIs) provided by SPECTRUM Element

Manager for Windows, SPECTRUM Portable Management

Applications (SPMAs), or SPECTRUM software packages.

8H02-16 User’s Guide 5-3

Chapter 5: COM Port and Telnet Connections

5.5

RUNTIME IP ADDRESS DISCOVERY

Upon power up, the 8H02-16, through a function called Runtime IP

Address Discovery, sends out a RARP and BootP request over the network to determine its IP address. This function allows the loading of an IP address into NVRAM on the 8H02-16 without using Local

Management. For information on setting up a workstation to act as a server to respond to a RARP or BootP request, refer to the specific workstation documentation.

5.6

COM PORT AND TELNET CONNECTIONS

Once the 8H02-16 has a valid IP address, establish a Telnet session with

Local Management from any TCP/IP based node on the network. Telnet connections to the 8H02-16 require the community name passwords

assigned at the SNMP Community Names screen. Refer to Section 6.7,

SNMP Community Names Screen, of this manual for additional

information about community names.

NOTE

Refer to the instructions included with the Telnet application for information about establishing a Telnet session.
