Chapter 3: Installation

3. Installation
3.1 Selecting a Site for the Switch
As with any electric device, you should place the switch where it will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select should meet the following requirements:
• The ambient temperature should be between -40 to +167° F (-40°C to +75° C).
• The relative humidity should be less than 95 percent, noncondensing.
• Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards.
• Make sure that the switch receives adequate ventilation. Do not block the ventilation holes on each side of the switch.

3.2 Connecting to Power
Use redundant DC terminal block power inputs or 12-VDC jack.

3.2.1 12-VDC Jack
Step 1: Connect the supplied AC to DC power adapter to the receptacle on the top side of the switch.
Step 2: C
onnect the power cord to the AC to DC power adapter and attach the plug to a standard AC outlet with the
appropriate AC voltage.

3.2.2 Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources. You only need to have one power input connected
to run the switch.
Step 1: Connect the DC power cord to the pluggable terminal block on the switch, and then plug it into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the switch.

Chapter 4: Switch Management

4. Switch Management
This chapter explains the methods that you can use to configure management access to the switch. It describes the types of
management applications and the communication and management protocols that deliver data between your management
device (workstation or personal computer) and the system. It also contains information about port connection options.

4.1 Management Access Overview
The switch gives you the flexibility to access and manage the switch using any or all of the following methods.
The Web browser interface and administration console (CLI) support are embedded in the switch software and are available for
immediate use.

4.2 Administration Console (CLI)
The administration console is an internal, character-oriented, Command-Line Interface (CLI) for performing system administration
such as displaying statistics or changing option settings.
Using this method, you can view the administration console from a terminal, personal computer, Apple® Macintosh´®, or
workstation connected to the switch’s console port.
There are two ways to use this management method: direct access or modem access. The following sections describe these
methods.

4.2.1 Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a terminalemulation program (such as HyperTerminal) to the switch console port.
When using the management method, configure the terminal-emulation program to use the following parameters (you can
change these settings after login):
Default parameters:
• 115,200 bps
• 8 data bits
• No parity
• 1 stop bit
This management method is often preferred because you can remain connected and monitor the system during system reboots.
Also, certain error messages are sent to the serial port, regardless of the interface through which the associated action was
initiated. A Macintosh or PC attachment can use any terminal-emulation program for connecting to the terminal serial port.
A workstation attachment under UNIX® can use an emulator such as TIP.

Page 20

724-746-5500 | blackbox.com

Chapter 4: Switch Management

4.2.2 Modem Access
You can access the switch’s administration console from a PC or Macintosh using an external modem attached to the console
port. The switch management program provides the Console Port screen, accessible from the Basic Management screen that lets
you configure parameters for modem access.
When you have configured the external modem from the administration console, the switch transmits characters that you have
entered as output on the modem port. The switch echoes characters that it receives as input on the modem port to the current
administration console session. The console appears to be directly connected to the external modem.

4.3 Web Management
The switch provides a browser interface that lets you configure and manage the switch remotely.
After you set up your IP address for the switch, you can access the switch’s Web interface applications directly in your Web
browser by entering the IP address of the switch. You can then use your Web browser to list and manage switch configuration
parameters from one central location, just as if you were directly connected to the switch’s console port.

4.4 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the switch. This management method requires the
SNMP agent on the switch and the SNMP Network Management Station to use the same community string. This management
method, in fact, uses two community strings: the get community string and the set community string. If the SNMP Network
management station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get
community string, it can only read MIBs. The default get and set community strings for the switch are public.

4.5 Protocols
The switch supports the following protocols:
Virtual terminal protocols, such as Telnet
A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a management session from a
Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on the
switch before you can establish access to it with a virtual terminal protocol.
NOTE: Terminal emulation is different from a virtual terminal protocol in that you must connect a terminal directly to the console
port.
Simple Network Management Protocol (SNMP)
SNMP is the standard management protocol for multivendor IP networks. SNMP supports transaction-based queries that allow
the protocol to format messages and to transmit information between reporting devices and data-collection programs. SNMP
runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode service.

4.6 Management Architecture
All of the management application modules use the same Messaging Application Programming Interface (MAPI). By unifying
management methods with a single MAPI, configuration parameters set using one method (e.g., console port) are immediately
displayed by the other management methods (e.g., SNMP agent of Web browser).
The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that the switch
is compatible with, and will interoperate with, other solutions that adhere to the same open standard.

Chapter 5: SNMP and RMON Management

5. SNMP and RMON Management
This chapter describes the switch’s Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON) capabilities.

5.1 Overview
RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base). RMON is a system defined by the
Internet Engineering Task Force (IETF) document RFC 2819, which defines how networks can be monitored remotely.
RMONs typically consist of two components: an RMON probe and a management workstation:
• T he RMON probe is an intelligent device or software agent that continually collects statistics about a LAN segment or VLAN.
The RMON probe transfers the collected data to a management workstation on request or when a pre-defined threshold is
reached.
• T he management workstation collects the statistics that the RMON probe gathers. The workstation can reside on the same
network as the probe, or it can have an in-band or out-of-band connection to the probe.
The switch provides RMON capabilities that allow network administrators to set parameters and view statistical counters defined
in MIB-II, Bridge MIB, and RMON MIB. RMON activities are performed at a Network Management Station running an SNMP
network management application with graphical user interface.

5.2 SNMP Agent and MIB-2 (RFC 1213)
The SNMP Agent running on the switch manager CPU is responsible for:
• Retrieving MIB counters from various layers of software modules according to the SNMP GET/GET NEXT frame messages.
• Setting MIB variables according to the SNMP SET frame message.
•G
enerating an SNMP TRAP frame message to the Network Management Station if the threshold of a certain MIB counter is
reached or if other trap conditions (such as the following) are met:
WARM START
COLD START
LINK UP
LINK DOWN
AUTHENTICATION FAILURE
RISING ALARM
FALLING ALARM
TOPOLOGY ALARM
MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-II covers all manageable objects
from layer 1 to layer 4, and, as a result, is the major SNMP MIB supported by all vendors in the networking industry. The switch
supports a complete implementation of SNMP Agent and MIB-II.

5.3 RMON MIB (RFC 2819) and Bridge MIB (RFC 1493)
The switch provides hardware-based RMON counters in the switch chipset. The switch manager CPU polls these counters
periodically to collect the statistics in a format that complies with the RMON MIB definition.

5.4 RMON Groups Supported
The switch supports the following RMON MIB groups defined in RFC 2819:
• RMON Statistics Group – maintains usage and error statistics for the switch port being monitored.
• RMON History Group – gathers and stores periodic statistical samples from the previous Statistics Group.

Page 22

724-746-5500 | blackbox.com

Chapter 5: SNMP and RMON Management

•R
MON Alarm Group – allows a network administrator to define alarm thresholds for any MIB variable. An alarm can be
associated with Low Threshold, High Threshold, or both. A trigger can trigger an alarm when the value of a specific MIB
variable exceeds or falls below a threshold.
• RMON Event Group – allows a network administrator to define actions based on alarms. SNMP Traps are generated when
RMON Alarms are triggered. The action taken in the Network Management Station depends on the specific network
management application.

5.5 Bridge Groups Supported
The switch supports the following four groups of Bridge MIB (RFC 1493):
• The dot1dBase Group – a mandatory group that contains the objects applicable to all types of bridges.
• T he dot1dStp Group – contains objects that denote the bridge’s state with respect to the Spanning Tree Protocol. If a node does
not implement the Spanning Tree Protocol, this group will not be implemented. This group is applicable to any transparent only,
source route, or SRT bridge that implements the Spanning Tree Protocol.
• T he dot1dTp Group – contains objects that describe the entity’s transparent bridging status. This group is applicable to
transparent operation only and SRT bridges.
• The dot1dStatic Group – contains objects that describe the entity’s destination-address filtering status. This group is applicable
to any type of bridge that performs destination-address filtering.

7. Command-LIne Management
The switch provides a command-line console interface for configuration purposes. The switch can be configured either locally
through its RS-232 port or remotely via a Telnet session. For the latter, you must specify an IP address for the switch first.
This chapter describes how to configure the switch using its console by Command Line.

7.1 Administration Console
Connect the DB9 straight cable to the RS-232 serial port of the device to the RS-232 serial port of the terminal or computer
running the terminal emulation application.
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal) to the switch console port.
When using the management method, configure the terminal-emulation program to use the following parameters (you can
change these settings after login):
Default parameters:
115,200 bps
8 data bits
No parity
1 stop bit
