Accessing the Control Terminal Port

Accessing the Control Terminal Port

Introduction

Once you have powered on the PathBuilder S21x switch, you can access the Control

 

Terminal Port from the PC or terminal attached to the CTP port.

This section does not provide all information about accessing the CTP. For more

 

 

 

information on accessing and using the CTP refer to the Basic Configuration

 

 

 

Manual (Part Number T0113).

Procedure

 

 

 

Follow these steps to access the PathBuilder S21x switch CTP Main menu:

 

 

 

Note

 

 

 

 

 

 

 

 

 

This procedure assumes that a PC or terminal is connected to the PathBuilder

 

 

 

S21x switch using the CTP access cable.

Step

Action

1

Set your terminal, or terminal emulation software, to VT100, 9600 bps,

 

8 bit, no parity, 1 stop bit.

 

 

2

Type <CR> until either an asterisk (*) or the OK prompt appears.

 

 

3

When you see OK, type atds0 <CR>. When you see the asterisk (*) type

 

.ctp.

 

The CTP banner will appear. If this banner does not appear, verify that

 

these steps have been followed correctly.

 

 

4

Type <CR> at the password prompt, if no password has been set.

 

 

CTP Access Via

Another way to connect to the CTP, after the node is configured and operational, is to

Remote Telnet

access remotely via your established IP network by telneting into the node from an

 

IP network-based personal computer or workstation. You can connect to the CTP by

 

entering atds0 <CR> after the PathBuilder S21x switch outputs the OK prompt.

CTP Access Via

 

If the PathBuilder S21x switch is operating in an X.25 network, or if Frame Relay

Remote X.25 or

Annex-G is used to connect with other 3Com PathBuilder S200 series switches, you

Frame Relay

can access the PathBuilder S200 series switch CTP remotely by making a Switched

Network

Virtual Circuit (SVC) call to the node and specifying subaddress 98.

The S21x supports both Fast Ethernet and Gigabit Ethernet connections, providing flexibility for different networking demands.

In addition to its port capabilities, the 3Com S21x incorporates advanced Power over Ethernet (PoE) technology. This feature enables the switch to deliver power to connected devices such as IP cameras, VoIP phones, and wireless access points directly through the network cable. This not only reduces the need for external power sources but also simplifies installation and lowers overall costs.

Another significant characteristic of the S21x is its Layer 2 switching capabilities. This means the device is equipped to handle basic data switching tasks efficiently, including VLAN support for network segmentation and traffic management. VLANs enhance security by isolating sensitive data traffic within specific segments, providing an additional layer of protection for network resources.

The 3Com S21x is also designed with ease of management in mind. It utilizes a user-friendly web-based interface that allows IT staff to configure and monitor the switch effortlessly. This accessibility ensures that even those with minimal networking experience can manage the device effectively, reducing the likelihood of configuration errors and downtime.

Furthermore, the S21x series is built with reliability at its core. The hardware is designed to withstand typical operating conditions in an office environment, minimizing the risk of failure and ensuring consistent performance. Coupled with a focus on energy efficiency, this series helps businesses reduce their operational costs while maintaining a green footprint.

In summary, the 3Com S21x series stands out in networking solutions for small to medium-sized enterprises, featuring a robust combination of port capacity, PoE support, Layer 2 functionality, easy management, and reliability. Organizations looking to enhance their network performance will find the S21x to be an invaluable asset, capable of growing with their needs while ensuring efficient and secure connections.
