Unpacking Your Switch
Make sure that you receive all the items shown in . 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:
•
Assemble the network devices you intend to connect to the switch. These devices must support either 10BaseT or 100BaseTX. For example, the Cisco 1538 series Micro Hub or any of the Cisco 1700 series routers are compatible devices.
•
Select your cabling:
•
To connect a compatible router, server, PC, or workstation, you must provide straight-through Ethernet cables.
For information on cabling the switch to a compatible network device, see "Connecting Network Devices to the Micro Switch" section.
•
To connect a 10- or 100-Mbps hub without an MDI/MDI-X button, provide one 100BaseTX crossover Ethernet cable for each hub. To connect a compatible hub that has an MDI/MDI-X button, such as a Cisco 1538 series Micro Hub, provide a 100BaseTX straight-through Ethernet cable.
•
To connect a compatible switch such as another Micro Switch, provide one 100BaseTX crossover Ethernet cable for each switch you plan to connect.
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:
•
Verify that the switch is operational by running the power-on self-test (POST).
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" on page 2-11.
•
Install the switches in a stack configuration.
•
Connect power to the switch.
•
Connect other network devices to the switch.
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.
•
Connect the console port of the Micro Switch to a terminal or PC to monitor and configure the switch.
•
Access the Micro Switch management interface.
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 ).
The switch begins the POST after power up. POST consists of the eight individual tests in . 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):
•
All POST tests passed—If the POWER LED is green and all of the port LEDs are off, no problems were detected. The switch is fully operational.
Note
After POST completes (and if there are devices connected to the switch ports), Spanning-Tree Protocol (if enabled) immediately turns the port LEDs green. The forwarding state is delayed to allow the Spanning-Tree Protocol to discover the network topology and to ensure no temporary loops are formed. Spanning-tree discovery takes approximately 30 seconds to complete, and no packet forwarding takes place during this time.
•
Nonfatal failure(s) detected—If the POWER LED is amber and the switch is functional, POST detected one or more nonfatal failures. Although the switch is still operational and can forward packets, it might not operate optimally. Refer to the POST failure message displayed on the diagnostic console screen, identifying the nonfatal failure(s) detected (See "Understanding POST Results" on page 4-3).
•
Fatal failure(s) detected—POST stops when it encounters a fatal failure. If the POWER LED is amber and a port LED is blinking green, POST detected a fatal failure. The switch is not operational, but the blinking port LED indicates which test failed.
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 on page 4-4 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 .
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 .

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:
•
9600 baud
•
8 data bits
•
1 stop bit
•
No parity
•
No flow control
You can change the console port characteristics of the switch from the web-based System Configuration Page (see the "Changing the System Configuration" section on page 3-29) or by using the terminal command from the command-line interface (CLI).
Note
Make sure the settings of the console port and the management station or the modem match.
Step 2
Connect one end of the supplied rollover console cable to the console port, as shown in .
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.
Note
If you are connecting the switch to a Sun workstation (or to a management station with a female DB-25 serial connector), use a male-to-male gender changer to attach the supplied RJ-45-to-RJ-45 console cable and a RJ-45-to-DB-25 female DTE adapter to the management station.
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 "" 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:
•
Following the switch start-up prompts displayed from a terminal emulation program on your management station. This section provides information on using these start-up prompts.
or
•
Using Cisco ConfigMaker if your management station is a PC running Microsoft Windows 95, Windows 98, or Windows NT 4.0. For information about Cisco ConfigMaker, refer to the Cisco ConfigMaker software.
You should contact your system administrator for the following information:
•
Switch IP address
•
Subnet mask (netmask)
•
Default gateway (router)
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 "" chapter.
Note
After POST completes (and if there are devices connected to the switch ports), Spanning-Tree Protocol (if enabled) immediately turns the port LEDs green. The forwarding state is delayed to allow the Spanning-Tree Protocol to discover the network topology and to ensure no temporary loops are formed. Spanning-tree discovery takes approximately 30 seconds to complete, and no packet forwarding takes place during this time.
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
Note
If the management station from which the Cisco 1548 Switch Manager is used is not on the same IP subnet as the switch, you must also assign a default gateway (the router for the local subnet).
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
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:
•
Java
•
JavaScript
•
Set the caching of pages to Every time in Communicator or
Every visit to the page in Internet Explorer.
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
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.

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
•
Use the default community strings
•
Read community string. The default is public.
•
Write community string. The default is private.
•
Assign community strings by using the SNMP Management Page or by using the snmp-server community command
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 File Transfer Protocol (FTP) to access the ftp.cisco.com server.

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 () 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
Chapter 3, "Configuring and Monitoring from the Hub Manager," for configuration and monitoring information.
