Make sure that you receive all the items shown in Figure 2-1. If any items are missing or damaged, contact your Cisco reseller.


Figure 2-1: Micro Switch Box Contents

Preinstallation

Before you begin installing the switch:

Note If you plan to connect a PC or workstation that runs at 100 Mbps, make sure it has a 100  Mbps-capable network interface card (NIC) installed.

Installing the Switch

These are the major steps for installing your Micro Switch:

TimeSaver If you are installing more than one Micro Switch, complete the next step. If you are installing only one switch, go directly to "Connecting the Power Cord".
TimeSaver If you plan to use the Micro Switch management features, complete the next two steps. If you do not plan to manage your switch, skip these steps.

Using POST to Pretest the Switch Operation

Before installing and cabling the switch, you might want to power up the switch and verify that it is operational.

To power up the switch, connect one end of the AC power cord to the AC power connector on the switch and the other end of the cord to a power outlet (see Figure 2-5).

The switch begins the POST after power up. POST consists of the eight individual tests in Table 4-1. The port LEDs show which test the switch is executing. As each test executes, a port LED turns green. For example, if the LED for port 4 is green, the boot code test (test  1) is being executed. On the switch, the port LED for port 4 turns green first, followed by ports  3, 2, 1, 8, 7, and so on. The LED turns off after the test completes. The POWER LED is solid amber until POST completes.

When POST completes, the following conditions can exist (if other devices are not connected to the switch):

You should inform your system administrator if one or more nonfatal failures are detected. Contact your Cisco representative or reseller for support if any fatal failures are detected.

The "Understanding POST Results" section provides additional information, including the possible causes of nonfatal and fatal failures.

Installing the Switch in a Stack

Each switch comes with a stacking clip and a screw that are used to keep multiple devices together in a stack. Before using the clip, you must assemble the clip and the screw, as shown in Figure 2-2.

TimeSaver If you are using only one switch and no other Cisco Networked Office devices, skip this step, and go to the "Connecting the Power Cord" section.

Figure 2-2: Assembling the Stacking Clip and Fastener

After pushing the fastener into the stacking clip, use the clip as shown in Figure 2-3.

Adding or Removing a Switch from a Stack

Figure 2-3 shows how to stack a Micro Switch with other Cisco Networked Office devices, and Figure 2-4 shows how to remove devices from the stack.

Warning
Unplug the power cord before you work on a system that does not have an on/off switch.

Connecting to the Console Port

To connect the RJ-45 console port of the Micro Switch to a management station or modem, you must use the supplied RJ-45-to-RJ-45 rollover console cable and the appropriate adapter and follow these steps.

Note The rollover console cable and a RJ-45-to-DB-9 female DTE adapter are supplied with the switch. If your management station requires a different adapter---such as a RJ-45-to-DB-25 female DTE or RJ-45-to-DB-25 male DCE adapter---you must provide it.

Step 1 Configure the switch console port settings to match the management station or modem. These are the default settings of the console port:

You can change the console port characteristics of the switch from the web-based System Configuration Page (see the "Changing the System Configuration" section) or by using the terminal command from the command-line interface (CLI).

Step 2 Connect one end of the supplied rollover console cable to the console port, as shown in Figure 2-12.

Caution
Do not connect an actual telephone line, an ISDN line, or an Ethernet cable to this console port. Damage to the switch can result. Make sure you use the supplied RJ-45-to-RJ-45 rollover cable and adapters to connect the console port to the management station or modem.

Figure 2-12: Connecting to the Console Port

Step 3 Attach the appropriate adapter, such as the supplied RJ-45-to-DB-9 female DTE adapter (labeled Terminal), to a management station or modem.

Step 4 Connect the other end of the supplied console cable to the adapter.

Now that the switch is connected to a management station, you can now assign IP information to the switch (see "Assigning IP Information to the Switch" section.

Connector and cabling specifications for the console port are in the "Specifications for the Micro Switch" appendix.

Assigning IP Information to the Switch

After you install the switch and connect it to a management station, you can assign IP information to the switch. IP information identifies the switch to the network and is necessary to configure and monitor the switch through the Cisco 1548 Switch Manager, the CLI, or SNMP.

You can assign IP information to the switch by either:

or

You should contact your system administrator for the following information:

To assign IP information to the switch, follow these steps:

Step 1 From your management station, start the terminal emulation program.

After POST completes, the Continue with configuration dialog? prompt appears on the management station, and you can then follow the prompts to assign IP information to the switch. If the Continue with configuration dialog? prompt does not appear, see the "Troubleshooting" chapter.

Step 2 From the terminal or PC, enter Y:

    Continue with configuration dialog? [yes/no]: Y

Step 3 Enter the IP address (for example: 10.1.105.20):

    Enter IP address: 10.1.105.20

Step 4 Enter the subnet mask (IP netmask) (for example: 255.255.255.0):

    Enter IP netmask: 255.255.255.0

Step 5 Enter the IP address of the default gateway (for example: 10.1.105.254):

    Enter IP default gateway: 10.1.105.254

The following information is displayed:

    The following configuration command script was created:
ip address 10.1.105.20 255.255.255.0
ip default-gateway 10.1.105.254
!
end

Step 6 Enter Y:

    Use this configuration? [yes/no]: Y

The following information is displayed:

    Building configuration...
Use the enabled mode `configuration' command to modify this configuration.
 
Press RETURN to get started.

Pressing Return opens a CLI session

Step 7 Exit from the terminal session.

Accessing the Management Interfaces

After you assign IP information to the switch, you can access the switch management interfaces. This section provides information for accessing the Cisco 1548 Switch Manager, the CLI, and SNMP and MIB files.

Accessing the Cisco 1548 Switch Manager

To access the switch manager, all you need is the IP information of the switch (and the password if one has been assigned). IP information for the switch is usually assigned when the switch is first started up after installation. (See the "Assigning IP Information to the Switch" section.)

Note You can access the switch manager from a PC connected to one of the 10/100 network ports. Therefore, make sure that you do not disable or otherwise misconfigure the port through which you are communicating with the switch. You might want to write down the port number you are connected to. Make changes to the switch IP information with care.

To access the switch manager, follow these steps:

Step 1 Start Netscape Communicator (4.03 or higher) or Microsoft Internet Explorer (4.01 or higher).

Step 2 Ensure that the following browser features are enabled:

Step 3 Enter the IP address of the switch in the Location field if you are using Communicator (the Address field if you are using Internet Explorer) to display the switch manager Home Page (Figure 2-13).


Figure 2-13: Home Page
Note You can bookmark the switch IP address to retrieve the switch manager for later use. If you are using Communicator, choose the Communicator menu option, and select Bookmarks  >  Add Bookmark. If you are using Internet Explorer, choose the Favorites menu option, and select Add to Favorites. Do not use the right mouse button to bookmark the switch IP address; doing so only saves the specific frame (image) of the switch manager page.

Accessing the CLI

You can access the CLI

When you access the CLI and a password has been defined, the following prompt is displayed:

Cisco Systems Console
Enter Password:

Enter the password. The hostname> prompt is displayed after you enter the correct password.

For complete information about the CLI, refer to the Cisco 1548M Micro Switch 10/100 Command Reference.

Accessing the MIB Files through SNMP

You can access the switch MIB files through SNMP. The following MIB files contain variables that can be set or read to provide information about the switch and the traps generated by the switch.

If you are going to manage the switch by using SNMP and the MIB files, the Read and Write community strings need to be set. To do this, you can either

Note Wait approximately 30 seconds for the changes to be saved to permanent storage before turning off the switch, or the changes might not be saved.

You can obtain a copy of the MIB files in the following ways:

Using FTP to Access the MIB Files

To obtain a MIB file, follow these steps:

Step 1 Use FTP to access the server ftp.cisco.com.

Step 2 Log in with the username anonymous.

Step 3 Enter your e-mail name when prompted for the password.

Step 4 At the ftp> prompt, change directories to /pub/MIBs.

Step 5 Use the get README command to display the readme file listing available files.

Step 6 Use the get MIB_filename command to get a copy of the MIB file.

Using CCO to Access the MIB Files

To access the MIB files from CCO, click Software & Support to display the Software Center site.

CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously: a character-based version and a multimedia version that resides on the World Wide Web (WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can access CCO in the following ways:

For a copy of CCO's Frequently Asked Questions (FAQ), contact cco-help@cisco.com. For additional information, contact cco-team@cisco.com.

Remote Monitoring

The Remote Monitoring (RMON) MIB is used by network managers to monitor remote devices. An RMON implementation consists of a software probe that continually collects statistics about a LAN and a management station that communicates with the probe. The probe transfers information to the management station on request or when a predefined threshold is crossed.

The switch supports four RMON groups (Table 2-2) as defined in RFC 1757. Default statistic rows are created for each port when you start the switch. You can obtain information about the four supported groups by using any SNMP management application.


Table 2-2: RMON Groups and Their Functions
Group Name Description

Statistics

This group collects traffic and error statistics for a specific interface. For example, you could use this group to determine how many error packets have been seen on a given port.

Statistics from this group can be used by the history group to record historical views of network performance. A statistics row is established by default for each switch port.

History

This group periodically samples the counters generated by the statistics group. This information can be used to establish baseline information regarding network activity. You can define the intervals you want to record information for, and you can define how many of the samples are to be stored.

Note RMON statistics gathering has a maximum limit of 50 history buckets per historyControlTable entry.

Alarm

This group generates alarms according to user-defined thresholds. You could, for example, configure RMON to generate an alarm when alignment errors on a port exceeded a predefined limit. Rising and falling thresholds can be defined, and the events group can generate traps and automated responses based on the alarms.

Event

This group sends traps to the management station based on information (alarms) received from the alarm group.

Where to Go Next

Now that you have installed and assigned IP information to the switch, continue to
"Configuring and Monitoring from the Hub Manager," for configuration and monitoring information.
