Powering Up and Using POST to Test the Switch
Before installing and connecting the switch to other network devices, 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 power cord to a power outlet. If your switch connects to the RPS, see the "Power Connectors" section and the Cisco RPS documentation.
As the switch powers up, it begins the power-on self-test (POST), the 13 individual tests listed in . The port LEDs show which test the switch is executing. At power up, all port LEDs are green. As each test executes, a port LED turns off. For example, if the LED for port 4x is off, the console port test (test 4) is being executed. The port LED for port 16x turns off first, followed by ports 12x, 11x, 10x, and so on. The LEDs for ports 15x, 14x, 13x are not used during POST. The expansion port LEDs (A and B) are not used during POST.
When POST ends, the following conditions can exist:
•All POST tests passed—If the SYSTEM LED is green and all of the port LEDs are off, no problems were detected. The switch is fully operational.
Note If there are devices connected to the switch ports when POST ends, Spanning-Tree Protocol (if enabled) immediately turns those port LEDs amber. The forwarding state, even if the Port Fast mode is enabled, 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, and no packets are forwarded during this time. After the initial discovery, ports with Port Fast mode enabled go directly from the blocking state to the forwarding state.
•Nonfatal failure(s) detected—If the SYSTEM LED is amber and the switch is functional, POST detected one or more nonfatal failures. The switch is still operational and can forward packets, but it might not operate optimally. The displays the POST failure message that identifies the nonfatal failure(s) detected.
•Fatal failure(s) detected—POST completes all tests, even after detecting a fatal failure. If the SYSTEM LED is amber and one or more of the port LEDs are amber, POST detected one or more fatal failures. The switch is not operational, the management console is not available, and the amber port LED(s) indicate which test(s) failed.
The "Understanding POST Failures" section provides additional information, including the possible causes of nonfatal and fatal failures. For information about how to display POST results, see the "Starting Up the Switch and Displaying the POST Results" section.
Note Inform your system administrator about any POST failures. Contact your Cisco representative or reseller for support if any POST failures are detected.
Installing the Switch on a Table or Shelf
Caution Before you perform the following steps, be sure the switch is powered off and is not connected to a power source.
To install the switch on a table or shelf, follow these steps:
Step 1 Locate the adhesive strip with the rubber feet that shipped with the switch.
Step 2 Attach the rubber feet to the round recesses on the bottom corners of the switch.
Step 3 Place the switch on a table or shelf close to an AC power receptacle.
Continue to the procedures in the "Connecting to the Console Port" section.
Installing the Switch in a Rack
The rack-mounting brackets supplied with the switch can be attached to a 19-, 23-, or 24-inch rack. Figure 2-1 shows which mounting holes attach to the rack.
Figure 2-1 Bracket Mounting Points
Caution Before you perform the following steps, be sure the switch is powered off and is not connected to a power source.
Note Some switches are shipped with screws installed in the top rack-mounting holes closest to the front panel. If you want to rack-mount the switch with the front panel forward, remove these screws before attaching the mounting brackets. Do not use these screws to attach the mounting brackets to the switch. Use the screws supplied with the brackets.
To attach the brackets and install the switch in 19-, 23-, and 24-inch racks, follow these steps:
Step 1 Place the switch on a level surface.
Step 2 Use two of the supplied Phillips flat-head or truss-head screws to attach a mounting bracket to each side of the switch. Secure all four screws tightly, but do not overtighten them.
The bracket orientation and the screws you use depend on whether you plan to use a 19-, 23-, or a 24-inch rack:
•For a 19-inch rack-mount, use the Phillips flat-head screws to attach the long side of the bracket to the switch.
•For a 23- or 24-inch rack-mount, use the Phillips truss-head screws to attach the short side of the bracket to the switch.
Figure 2-2, Figure 2-3, and Figure 2-4 show how to attach one bracket to one side of the switch. Follow the same steps for the opposite side.

Step 3 Use the four supplied Phillips machine screws to attach each bracket to the rack, as shown in .
Figure 2-5 Attaching the Switch to a Rack (Front Panel Forward)
Step 4 Attach the cable guide and secure the cables in the cable guide so that the cables do not obscure the switch or other devices in the rack. If the switch is in a 19-, 23-, or 24-inch rack, you can use the supplied black screws to attach the cable guide to the left or right rack-mount bracket, as shown in .
Figure 2-6 Attaching a Cable Guide
Continue to the procedures in the "Connecting to the Console Port" section.
Installing the Switch on a Wall
Caution Before you perform the following steps, be sure the switch is powered off and is not connected to a power source.
Note Some switches are shipped with screws installed in the top rack-mounting holes closest to the front panel. Do not use these screws to attach the mounting brackets to the switch. Use the screws supplied with the brackets.
To attach the brackets and attach the switch parallel or vertically to a wall, follow these steps:
Step 1 Place the switch on a level surface.
Step 2 Use two of the supplied Phillips truss-head or flat-head screws to attach a mounting bracket to each side of the switch. Secure all four screws tightly, but do not overtighten them.
The bracket orientation depends on whether you plan to attach the switch parallel or vertically to a wall:
•For a parallel wall-mount, use the Phillips truss-head screws to attach the short side of the bracket to the switch.
•For a vertical wall-mount, use the Phillips truss-head screws to attach the long side of the bracket to the switch.
Figure 2-7 shows how to attach one bracket to one side of the switch. Follow the same steps for the opposite side.
Figure 2-7 Attaching Brackets for Parallel and Vertical Wall-Mounting
Step 3 Attach the switch to a wall. For the best support of the switch and cables, make sure the switch is securely attached to a wall stud or to a firmly attached plywood mounting backboard, as shown in . You must supply your own screws to attach the switch to the wall.
Figure 2-8 Attaching the Switch to a Wall
Continue to the procedures in the "Connecting to the Console Port" section.
Connecting to the Console Port
Note The rollover console cable and a RJ-45-to-DB-9 female DTE adapter are supplied. 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. For pinout information, see the "Console Port" section.
To connect the switch RJ-45 console port 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:
Step 1 Make sure the settings of the switch console port and the management station or the modem match.
These are the default settings of the switch console port:
•9600 baud
•8 data bits
•1 stop bit
•No parity
•No flow control
Although the Match Baud Rate option (autobaud) matches the baud rate of an incoming call, the switch uses its configured rate when dialing out. When a call is completed and the line disconnects, the switch always returns to its configured baud rate.
You can change the console port settings from the (see the "Changing the Console Port Settings and Upgrading the Firmware" section) or the (see the "RS-232 Interface Configuration Menu" section).
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 console cable and the appropriate adapter to connect the console port to the management station or modem.
Figure 2-9 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 rollover console cable and a RJ-45-to-DB-25 female DTE adapter to the management station. You must provide the gender changer and the DTE adapter because they are not supplied with the switch.
Step 4 Connect the other end of the supplied rollover console cable to the adapter.
Step 5 From your management station, start the terminal emulation program.
Continue to the procedures in the "Powering Up the Switch" section.
Connector and cabling specifications for the console port are in "."
Powering Up the Switch
If your configuration has an RPS, see the "Power Connectors" section and the Cisco RPS documentation.
Note The Catalyst 2820 switches do not support the fully-redundant configurations that are described in the Cisco RPS documentation. In addition, we recommend that you do not use the redundant-with-reboot configuration with the switch connected to the RPS and to the AC power plug, due to the reboot and downtime—approximately 30 seconds. If you do use the redundant with reboot configuration, always power up the switch before you power up the RPS to ensure correct operation. In circumstances where the RPS is first to power up, the LEDs might not indicate the actual state.
To power up the switch internal power supply after you install and connect it to a management station, follow these steps:
Step 1 Make sure that you have started the emulation software program (such as ProComm, HyperTerminal, tip, or minicom) from your management station.
Step 2 Connect one end of the AC power cord to the AC power connector on the switch.
Step 3 Connect the other end of the power cord to an AC power outlet.
As the switch powers up, it starts the series of self-tests described in the "Powering Up and Using POST to Test the Switch" section. When the switch completes POST, the (Figure 2-10) is displayed on the management station.
Continue to the procedures in the "Assigning IP Information and a Password to the Switch" section.
Assigning IP Information and a Password to the Switch
After POST completes, the (Figure 2-10) is displayed on the management station. From this logon screen, you can assign IP information and a privileged-level password to the switch. This section describes the importance of IP information and a password to the switch and describes how to assign this information to the switch.
IP Information
IP information identifies the switch on the network and is required to configure and monitor it as an individual switch. When you assign the switch its own IP address, you can manage it from its management interfaces (switch manager, management console, SNMP, or CLI). The switch retains its own IP address even when it joins or leaves a switch cluster.
If you do not assign an IP address to the switch, you must add the switch to a switch cluster and manage it through the command switch. Whether or not the switch has its own IP address, when the switch is a cluster member, it is managed and communicates with other member switches through the IP address of the command switch. If the switch leaves the cluster and it does not have its own IP address, you then must assign IP information to it to manage and monitor it as a nonmember switch.
Note We recommend that you assign an IP address to the switch even if the switch is or will be a cluster member so that if the switch is removed from the cluster, it remains manageable as a nonmember switch.
For more information about IP information, see the "Assigning or Changing IP Information" section or the "IP Configuration Menu" section.
Privileged-Level Password
A privileged-level password provides security against unauthorized access to the management interfaces (switch manager, management console, or CLI) and is required to access these interfaces.
Note When the switch is shipped, no password is assigned to it. However, a privileged-level password is required to access the Catalyst 2820 Switch Manager or to use Telnet access from a remote station. If you do not assign a password, this access will not be available until the switch joins a cluster or until you assign the switch a privileged-level password from the management console (see the "Console Settings Menu" section) through a direct connection to the switch console port.
When your switch is a cluster member, the highest privileged-level password for the command switch is the privileged-level password to the switch. The command-switch password overwrites any switch-specific passwords.
Note We do not recommend changing the password while the switch is a cluster member. This will cause a password mismatch, and you will have to manually enter the cluster member password to display the switch manager from the command switch. For more information about passwords, see the "Changing the Switch Password" section or the "Changing the Switch Password" section.
To assign IP information and a password to the switch, follow these steps from your management station:
Step 1 Enter the [I] IP Address option on the (Figure 2-10).

Connecting to the Switched 10BaseT Ports
You can connect the 10BaseT ports (ports 1x through 24x) to 10BaseT-compatible network devices, such as workstations, hubs, servers, routers, and other switches. All connections between the switch and the attached device(s) must be within 100 meters.
You must provide the Category 3, 4, or 5 cable(s) to connect any of these ports to the other 10BaseT device(s). Because these ports are internally crossed, they require a crossover cable to connect to hubs or other switches. When connecting to workstations, servers, or routers, these ports require a straight-through cable.
Note Always observe these general rules when connecting devices: Use a straight-through cable to connect two ports when one of the ports is designated with an X. Use a crossover cable to connect two ports when both ports are designated with an X.
The default duplex mode of these ports is half duplex. To change the duplex mode of these ports to full-duplex, use the switch manager, management console, or SNMP. (See the "Changing the Port Settings" section or the "Port Configuration Menu" section.)
Note For information about using the Half-duplex back pressure option on the 10-Mbps ports, see the "Half-Duplex Back Pressure on 10-Mbps Ports" section or the "System Configuration Menu" section.
To connect a switch 10BaseT port to another 10BaseT device, follow these steps:
Step 1 Connect one end of the Category 3, 4, or 5 cable to the 10BaseT port on the switch (Figure 2-12).
Note When connecting the switch to workstations, servers, and routers, ensure that the cable is a straight-through, twisted-pair cable. When connecting the switch to other switches or hubs, use a crossover cable.
Figure 2-12 Connecting to a 10BaseT Port
Step 2 Connect the other end of the cable to the 10BaseT port of the network device.
Step 3 Make sure that the LED for the port that you connected in Step 1 turns on.
If the port LED is not on, look for the following problems:
•The network device is not on.
•The Ethernet adapter in the network device is not operating correctly.
•The cable is damaged or is not connected correctly.
•You are using the wrong type of cable.
If you are connecting the switch 10-Mbps port to an end-station, which is configured for 100-Mbps, you need to reconfigure the end-station to operate at 10-Mbps.
Step 4 Repeat Steps 1 through 3 for each device that you are connecting to the switch.
Connector and cabling specifications for the 10BaseT ports are in "."
Connecting to the Switched AUI Port
The AUI port on the switch can connect to an Ethernet transceiver, which is then connected to a 10-Mbps Ethernet device through thick coaxial, thin coaxial, fiber-optic, or UTP cable. You must provide the Ethernet transceiver and cable to connect the AUI port to the other network device. Supported network and device distances vary depending on the type of Ethernet AUI transceiver used.
The type of cable you use (thick coaxial, thin coaxial, fiber-optic, or twisted-pair) depends on the AUI transceiver that you are using. For information about the cable types you can use, see the "Switched AUI Port" section.
Note Use a crossover cable if the transceiver is used to convert to a 10BaseT RJ-45 connector.
To connect the switch AUI port to an external transceiver, follow these steps:
Step 1 Slide the AUI slide latch bracket to the right, and attach the appropriate external transceiver to the AUI port on the switch.
Step 2 Slide the latch bracket to the left to lock the AUI transceiver to the port.
Step 3 Connect one end of the appropriate cable to the port on the AUI transceiver, as shown in .
Figure 2-13 Connecting to the AUI Port
Step 4 Connect the other end of the cable to the 10BaseT port of the network device.
Step 5 Check the LED on the AUI transceiver, or use the or the to check the AUI port status.
If the port LED is not on, or if the port status is not "Enabled," look for the following problems:
•The network device is not on.
•The Ethernet adapter in the network device is not operating correctly.
•The cable or transceiver is damaged or is not connected correctly.
•You are using the wrong type of cable.
If you are connecting the switch 10-Mbps port to an end-station, which is configured for 100-Mbps, you need to reconfigure the end-station to operate at 10-Mbps.
Connector and cabling specifications for the AUI port are in "."
Accessing the Management Interfaces
You can choose to use the default settings of the switch or to use the management interfaces to configure and monitor the switch.
This section describes how to access the following management interfaces if the switch is not a cluster member:
•Catalyst 2820 Switch Manager
•Management console and CLI
•SNMP
Access to the management console or the CLI requires a direct connection to the switch console port or a Telnet session. Access to the Catalyst 2820 Switch Manager, Cluster Management applications, or SNMP requires a connection to one of the switch network ports.
If the switch is a cluster member, you can access its management interfaces through the command switch. For information about accessing the switch from the command switch, refer to the Cisco IOS Desktop Switch Software Configuration Guide, Catalyst 2900 Series XL and Catalyst 3500 Series XL Cisco IOS Release 12.0(5)XP.
Accessing the Switch Manager
Note You access the switch manager from a management station that is connected to one of the switch 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 to which you are connected. Make changes to the switch IP information with care.

If the switch is a cluster member and does not have its own IP address, you need to use the command-switch IP address to display the Catalyst 2820 Switch Manager from a command switch Cluster Management application.
Step 2 Enter the switch password or, if the switch is a cluster member, the command-switch password at the prompt.
The switch manager is displayed (Figure 2-14).
Figure 2-14 Home Page
Continue to configure or monitor the switch from the switch manager, as described in "."
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 Management Console and CLI
To access the management console, follow these steps:
Step 1 Start up the emulation software (such as ProComm, HyperTerminal, tip, or minicom) on the management station.
Step 2 Establish a connection with the switch by either
•Connecting the switch console port to a management station or dial-up modem. For complete information, see the "Connecting to the Console Port" section.
•Using any Telnet TCP/IP package from a remote management station. The switch must have network connectivity with the Telnet client, and a switch password must have been configured.
The switch supports up to seven simultaneous Telnet sessions. Changes made by one Telnet user are reflected in all other Telnet sessions.
After you connect through the console port or through a Telnet session, the (Figure 2-15) is displayed on the management station.

Accessing MIB Files
You can access the switch MIB files through SNMP to configure and monitor the switch.
Note Wait approximately 1 minute for the changes to be saved to permanent storage before turning off the switch, or the changes might not be saved.
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 on the (Figure 3-7) or the (Figure 4-10) and (Figure 4-11).
You can obtain a copy of the MIB files using File Transfer Protocol (FTP) to access the ftp.cisco.com server.
To obtain a MIB file, follow these steps:
Step 1 Use FTP to access the server ftp.cisco.com, or enter ftp.cisco.com from your browser.
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/supportlists/wsc2820.
Step 5 Use the get supportlist.html command to get a list of the supported MIB files.
Step 6 Change directories to /pub/mibs/v1.
Step 7 Get the MIB files.
