Installation
This chapter contains detailed procedures for installing the Catalyst 2800 on a table, shelf, or rack, and connecting it to other devices. The first thing to do is to ensure that you have all the components. When unpacking the unit, turn to the "Packing List" section in the "Fast Install Guide" preface for the list of included items.
Installing Catalyst 2800 in a Rack
The nature of rack-mounted equipment requires that the following guidelines be observed:
•
If installed in a closed or multirack assembly, the temperature may be greater than normal room temperature. Ensure that the temperature around the unit does not exceed 40° C.
•
Install the Catalyst 2800 so that the amount of air flow required for safe operation is ensured.
•
Do not mount the Catalyst 2800 in a rack that may be overloaded or unevenly loaded.
•
Check the power supply to determine the effect power surges and overloading of circuits could have.
To install the unit in the rack:
Step 1
Position the unit on the rack by lining up the integrated mounting ears with the holes in the rack, as shown in .
Figure 4-1 Catalyst 2800 Installed in a Rack
Step 2
Attach the Catalyst 2800 unit to the rack with the four provided screws.
Step 3
Connect the power cord to the Catalyst 2800 and to the power outlet.
Step 4
Turn the unit on using the power switch on the rear panel.
The power LED will come on, and the Catalyst 2800 will automatically start a self-test. This test is described in the "Power-On Self-Test (POST)" section in this chapter.
Table and Shelf Installation
Use these instructions to install the Catalyst 2800 on a table or shelf.
Step 1
Attach the four rubber feet included in the cushioning kit to the bottom of the unit.
Step 2
Place the Catalyst 2800 unit on the table or shelf near a power source.
Step 3
Connect the power cord to Catalyst 2800 and to the power outlet.
Step 4
Turn the Catalyst 2800 on using the power switch on the rear panel.
The power LED will come on, and Catalyst 2800 will automatically start the series of tests described in the "Power-On Self-Test (POST)" section in this chapter.
Power-On Self-Test (POST)
When the Catalyst 2800 is first turned on it lights all LEDs and executes a Power-On Self-Test (POST). There are fifteen tests run in reverse order starting with number fifteen. As a test is running, the column of port LEDs with that test number are turned off. When the test passes, the LEDs are turned back on and the next test is performed. A complete description of the fifteen POST tests is included in the "POST Failure" section in the "" chapter.
Tests nine and ten each take about thirty seconds; the other tests last a few seconds each. If a test fails, the associated LED column remains off during the remainder of the tests. When all the tests have completed, the LEDs for each passed test remain on, and the LEDs for each failed test remain off. When all tests pass, all LEDs are turned off.
For more details about the POST, see the "POST Failure" section in the "" chapter.
Default Settings
The Catalyst 2800 is configured with the default settings shown in . See the "" chapter for descriptions of the Management Console menus listed below.
Table 4-1 Catalyst 2800 Default Settings
If you find some of these terms unfamiliar, they are described in detail in the "Concepts" chapter. See the "Configuration Menus" section in the "" chapter for instructions on changing the default settings. If you are using SNMP, you can set these parameters according to the list of supported MIB objects found in the "Standard MIBs and MIB Extensions" section in the "" chapter.
Connecting to Catalyst 2800 Ports
Once the Catalyst 2800 is installed you can begin connecting devices to its ports. Note that all UTP connections, whether 10Base-T, 100Base-TX, or FDDI UTP must be within 100 meters of the Catalyst 2800.
Note
Spanning tree takes more than thirty seconds to configure its topology. No packet forwarding takes place during this time.
Connecting to 10Base-T Ports 1 Through 24
Use the following procedure to connect the Catalyst 2800 to 10Base-T ports 1 through 24:
Step 1
Insert the cable into one RJ-45 connector as shown in Figure 4-2.
Figure 4-2 Inserting the Cable into the RJ-45 Connector
Note
Make sure the cable is wired for 10Base-T and that it is a straight-through twisted-pair cable. Pinouts for the cables are described in the "Catalyst 2800 Connector Pinouts" section in the "" appendix.
Step 2
Insert the other end of the cable into the RJ-45 connector of the target device. The link LED will light when both Catalyst 2800 and the connected device are turned on. If the link LED does not light, the device at the other end may not be turned on, there may be a cable problem or a problem with the adapter installed in the attached device. See the "" chapter for more information.
Step 3
Reboot the connected device as needed.
Repeat steps 1 through 3 for each device that needs to be connected.
Connecting to Port 25
Port 25 is described separately because it can be connected via an RJ-45 or AUI connector. Only one connector for the port can be used at a time. The Catalyst 2800 can self-sense the connector being used, and no configuration is necessary. You can also define which connector is to be used through the Catalyst 2800 management console as described in the "Port Configuration" section in the "" chapter, or with the objects listed in the "Standard MIBs and MIB Extensions" section in the "" chapter.
Figure 4-3 Connecting to Port 25
If you're using the RJ-45 connector, use the procedure in the "Connecting to 10Base-T Ports 1 Through 24" section in this chapter.
Connecting to the Expansion Slot Ports
Procedures for installing Catalyst 2800 modules in the Catalyst 2800 high-speed expansion slots are included in the Catalyst 2800 Modules User Guide.
Connecting via the AUI Connector
Use the AUI connector on the front panel to connect to an external transceiver for attachment to a thick coaxial, thin coaxial, or fiber-optic cable.
Step 1
Install the appropriate external transceiver on the network. Refer to the transceiver manual for installation instructions.
Step 2
Insert the AUI cable into the AUI connector on Catalyst 2800, as shown in .
Step 3
Slide the latch into the closed position.
Step 4
Attach the other end of the cable to the transceiver.
Figure 4-4 Connecting to the Network via the AUI Connector
Note
The maximum AUI cable length is 50 meters. The link LED is not active when the AUI connector is used.
Connecting a Terminal via the RS-232 Port
Use the RS-232 cable shipped with Catalyst 2800 to connect a terminal to the RS-232 port on the Catalyst 2800's back panel.
Figure 4-5 Inserting the RS-232 Connector
Step 1
Using the cable supplied with the Catalyst 2800, insert the connector into the receptacle as shown in .
Step 2
Insert the other end of the cable into the terminal.
Step 3
Boot the terminal emulation program on your terminal.
The management console logon panel appears.
Note
Use a null-modem cable when attaching to a modem.
The Catalyst 2800 is configured to expect the following parameters:
•
9600 baud
•
Eight data bits
•
One stop bit
•
