Configuring a Telnet Connection

You can access the terminal interface through a Telnet connection via the SCM

 LAN 

port. 

One SCM supports a terminal interface for up to 15 units in a single SC5000 shelf. A management 
session is active as soon as a valid login sequence is completed.

Making a Telnet Connection

1. Establish a Telnet connection to the SCM using a PC. Refer to the SpectraComm Manager 

Card Installation and Operation Manual as needed. When connection is made, the following 
screen appears. 

2. Enter the login password (

scmadmin

). 

Note

There is a 10-minute timeout programmed at the terminal interface. If you allow 10 minutes to pass with no 
activity, that is without pressing any key on the keyboard, the unit will terminate the session.

3. After the SCM verifies the login password, the Shelf Inventory screen appears (

Figure 2-3

). 

This is the point of access for any network element via its shelf slot number. 

Note

The SCM will display an alarm tag at the slot of any device with an alarm condition in effect.

Figure 2-3

Shelf Inventory Screen

4. Select a slot number to access the terminal interface of the SRM-6 or other device, and then 

press

 Enter

. The Main Menu appears for the selected device appears. 

5. For a description of all SRM-6 menu items, refer to Chapter 3, SRM-6 Operation & 

Diagnostics . For other elements in the shelf, refer to the associated manuals.
