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°C to 75℃ (-40 to 167 ).  
-The relative humidity should be less than 95 percent, non-condensing.  
-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.  
Connecting to Power  
12VDC DC Jack  
Step 1: Connect the supplied AC to DC power adapter to the receptacle on  
the back of the switch.  
Step 2: Connect the power cord to the AC to DC power adapter and attach  
the plug into a standard AC outlet with the appropriate AC voltage.

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.  
This chapter covers the following topics:

Standards, Protocols, and Related Reading  
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.

Black Box Hardened Managed Ethernet Switch  
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.  
Direct Access  
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]  
♦ 115,200bps  
♦ 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.

Black Box Hardened Managed Ethernet Switch  
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 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.  
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.  
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.

Black Box Hardened Managed Ethernet Switch  
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.  
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 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.

SNMP & RMON Management  
This chapter describes the switch’s Simple Network  
Management Protocol (SNMP) and Remote Monitoring  
(RMON) capabilities.  
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  
1757, which defines how networks can be monitored  
remotely.  
RMONs typically consist of two components: an RMON probe  
and a management workstation:  
- The 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.  
- The 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.  
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.  
- Generating 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

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.  
RMON MIB (RFC 1757) 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.  
RMON Groups Supported  
The switch supports the following RMON MIB groups defined in RFC 1757:  
- RMON Statistics Group – maintains utilization and error statistics for the  
switch port being monitored.

- RMON History Group – gathers and stores periodic statistical samples from  
the previous Statistics Group.  
- RMON 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 a threshold, falls below a threshold,  
or 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.  
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.  
- The 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.  
- The 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 which performs destination-address filtering.

function will allow members of a multicast group to leave the group  
immediately when an IGMP Leave Report Packet is received by the  
Switch.  
IGMP querier:  
1. Query-interval: Click in the “query-interval” textbox and specify a new  
number from 1 ~ 18000. The query-interval field is used to set the time  
(in seconds) between transmitting IGMP queries. Entries between 1 and  
18000 seconds are allowed. Default = 125.  
2. Max-response-time: Click in the “max-response-time” textbox and  
specify a new number from 1 ~ 124. This determines the maximum  
amount of time in seconds allowed before sending an IGMP response  
report. The max-response-time field allows an entry between 1 and 124  
(seconds). Default = 10.  
IGMP passive snooping:  
1. Report suppression: Click “report suppression” drop-down menu from  
“report suppression” drop-down list to choose “Enable” or “Disable” for  
the switch. Use this command to enable report suppression for IGMP  
version 1 and version 2. Report suppression does not apply to IGMP  
version 3, and is turned off by default for IGMP versionn1 and IGMP  
version 2 reports. The switch uses IGMP report suppression to forward  
only one IGMP report per multicast router query to multicast devices.  
When IGMP router suppression is enabled, the switch sends the first  
IGMP report from all hosts for a group to all the multicast routers. The  
switch does not send the remaining IGMP reports for the group to the  
multicast routers. This feature prevents duplicate reports from being  
sent to the multicast devices.

Command Line Console 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 later, you must specify an IP address for the  
switch first.  
This chapter describes how to configure the switch using its  
console by Commend Line.  
Administration Console  
Connect the DB9 null-modem or cross over 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]  
115,200bps  
8 data bits  
No parity
