Switch Installation

Installing the Switch Without the Rack

1.

Install the switch on a level surface that can safely support the weight of the switch

and its attached cables. The switch must have adequate space for ventilation and for

accessing cable connectors.

2.

Set the switch on a flat surface and check for proper ventilation. Allow at least 5 cm (2

inches) on each side of the switch and 15 cm (6 inches) at the back for the power

cable.

3.

Attach the rubber feet on the marked locations on the bottom of the chassis.

4.

The rubber feet, although optional, are recommended to keep the unit from slipping.

Figure 2-1. Install rubber feet for installations with or without a rack

Installing the Switch in a Rack

You can install the switch in most standard 19-inch (48.3-cm) racks. Refer to the illustrations

below.

1.

Use the supplied screws to attach a mounting bracket to each side of the switch.

2.

Align the holes in the mounting bracket with the holes in the rack.

Gigabit Combo Ports

In addition to the 24 10/100/1000 Mbps ports, the Switch features four Mini-GBIC Combo

ports. These four ports are 10/100/1000BASE-T copper ports (built-in) and Mini-GBIC ports

(optional). Please note that the Mini-GBIC ports are used instead of the built-in

10/100/1000BASE-T ports. The Mini-GBIC ports will not work simultaneously with its

corresponding 10/100/1000BASE-T port. For example, if port 24x is used on the Mini GBIC

module, port 24 is not available for the 10/100/1000BASE-T built-in port, and vice versa.

Redundant Power System

The switch supports dual, current-sharing, redundant power supplies.

Connecting the Console Port

The switch provides an RS-232 serial port that enables a connection to a computer or terminal

for monitoring and configuring the switch. This port is a DB-9 connector, implemented as a

DCE connection.

To use the console port, you need the following equipment:

•

A terminal or a computer with both a serial port and the ability to emulate a terminal

•

A RS-232 cable with a female DB-9 connector for the console port on the switch

To connect a terminal to the console port:

1. Connect the RS-232 cable directly to the console port on the switch, and tighten the

captive retaining screws.

2. Connect the other end of the cable to a terminal or to the serial connector of a

computer running terminal emulation software. Set the terminal emulation software as

follows:

1.

Select the appropriate serial port (COM port 1 or COM port 2).

3.

Set the data rate to 115200 baud.

4.

Set the data format to 8 data bits, 1 stop bit, and no parity.

5. Set flow control to

none

.

6. Under

Properties

, select

VT100 for Emulation

mode.

7. Select

Terminal keys

for

Function, Arrow, and Ctrl keys

. Ensure that you

select

Terminal keys

(

not

Windows keys

).

NOTICE:

When you use HyperTerminal with the Microsoft

®

Windows

®

2000

operating system, ensure that you have Windows 2000 Service Pack 2 or later

installed. Windows 2000 Service Pack 2 allows you to use arrow keys in

HyperTerminal’s VT100 emulation. See

www.microsoft.com

for information on

Windows 2000 service packs.

8. After you have correctly set up the terminal, plug the power cable into the

power receptacle on the back of the switch. The boot sequence appears in the

terminal.

9. After the boot sequence completes, the console login screen displays.

10. If you have not logged into the command line interface (CLI) program, press

the Enter key at the User name and password prompts. There is no default user

name and password for the switch, user names and passwords must first be

created by the administrator. If you have previously set up user accounts, log in

and continue to configure the Switch.

11. Enter the commands to complete your desired tasks. Many commands require

administrator-level access privileges. Read the next section for more

information on setting up user accounts. See the

Command Line Reference

on

the documentation CD for a list of all commands and additional information on

using the CLI.

12. When you have completed your tasks, exit the session with the

logout

command or close the emulator program.

Password Protection

The DES-6500 does not have a default user name and password. One of the first tasks when

settings up the switch is to create user accounts. If you log in using a predefined

administrator-level user name you have privileged access to the switch’s management

software.

After your initial login, define new passwords for both default user names to prevent

unauthorized access to the switch, and record the passwords for future reference.

To create an administrator-level account for the switch, do the following:

1.

At the CLI login prompt, enter

create account admin

followed by the <user

name> and press the Enter key.

2.

You will be asked to provide a password. Type the <password> used for the

administrator account being created and press the Enter key.

3.

You will be prompted to enter the same password again to verify it. Type the

same password and press the Enter key.

4.

Successful creation of the new administrator account will be verified by a

Success

message.

User names and passwords can be up to 15 characters in

length.

6

The sample below illustrates a successful creation of a

new administrator-level account with the user name “newmanager”.

NOTE:

Passwords are

case sensitive.

DES-6500:4#create account admin newmanager

Command: create account admin newmanager

Enter a case-sensitive new password:********

Enter the new password again for confirmation:********

Success.

DES-6500:4#

NOTICE:

CLI configuration commands only modify the

running configuration file and are not saved when the switch

is rebooted. To save all your configuration changes in

nonvolatile storage, you must use the

save

command to copy

the running configuration file to the startup configuration.

SNMP Settings

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer)

function designed specifically for managing and monitoring network devices. SNMP enables

network management stations to read and modify the settings of gateways, routers, switches,

and other network devices. Use SNMP to configure system features for proper operation,

monitor performance and detect potential problems in the switch, switch group or network.

Managed devices that support SNMP include software (referred to as an agent), which runs

locally on the device. A defined set of variables (managed objects) is maintained by the

SNMP agent and used to manage the device. These objects are defined in a Management

Information Base (MIB), which provides a standard presentation of the information controlled

by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and

the protocol used to access this information over the network.

The DES-6500 supports the SNMP versions 1, 2c, and 3.

You can specify which version of

the SNMP you want to use to monitor and control the switch.

The three versions of SNMP

vary in the level of security provided between the management station and the network

device.

In SNMP v.1 and v.2c, user authentication is accomplished using ‘community strings’, which

function like passwords.

The remote user SNMP application and the switch SNMP must use

the same community string. SNMP packets from any station that has not been authenticated

are ignored (dropped).

The default community strings for the switch used for SNMP v.1 and v.2c management access

are:

public

- Allows authorized management stations to retrieve MIB objects.

private

- Allows authorized management stations to retrieve and modify MIB objects.

SNMP v.3 uses a more sophisticated authentication process that is separated into two parts.

The first part is to maintain a list of users and their attributes that are allowed to act as SNMP

managers. The second part describes what each user on that list can do as an SNMP manager.

The switch allows groups of users to be listed and configured with a shared set of privileges.

The SNMP version may also be set for a listed group of SNMP managers. Thus, you may

create a group of SNMP managers that are allowed to view read-only information or receive

traps using SNMP v.1 while assigning a higher level of security to another group, granting

read/write privileges using SNMP v.3.

Using SNMP v.3 individual users or groups of SNMP managers can be allowed to perform or

be restricted from performing specific SNMP management functions. The functions allowed

or restricted are defined using the Object Identifier (OID) associated with a specific MIB. An

additional layer of security is available for SNMP v.3 in that SNMP messages may be

encrypted. To read more about how to configure SNMP v.3 settings for the switch read the

next section, Management.

Traps

Traps are messages that alert network personnel of events that occur on the Switch. The

events can be as serious as a reboot (someone accidentally turned OFF the Switch), or less

serious like a port status change. The Switch generates traps and sends them to the trap

recipient (or network manager). Typical traps include trap messages for Authentication

Failure, and Topology Change.
