Installation

This chapter is a detailed procedure for installing Catalyst 2100 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 section "Packing List" in the "Fast Install Guide" for the list of included items.

Installing Catalyst 2100 in a Rack

The nature of rack-mounted equipment requires that the following guidelines be observed:

• If installed in a closed or multi-rack 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 2100 so that the amount of air flow required for safe operation is ensured.
  

• Do not mount the Catalyst 2100 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.

Figure 4-1 : Catalyst 2100 Installed in a Rack

Step 2 Attach the Catalyst 2100 unit to the rack with the four provided screws.

Step 3 Connect the power cord to Catalyst 2100 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 Catalyst 2100 will automatically start a self-test. This test is described in the section "Power-On Self-Test (POST)" in this chapter.

Table and Shelf Installation

Use these instructions to install Catalyst 2100 on a table or shelf.

Step 1 Attach the four rubber feet included in the Catalyst 2100 cushioning kit to the bottom of the unit.

Step 2 Place the Catalyst 2100 unit on the table or shelf near a power source.

Step 3 Connect the power cord to Catalyst 2100 and to the power outlet.

Step 4 Turn Catalyst 2100 on using the power switch on the rear panel.

The power LED will come on and Catalyst 2100 will automatically start the series of tests described in the section "Power-On Self-Test (POST)."

Power-On Self-Test (POST)

When Catalyst 2100 is first turned on it lights all LEDs and executes a Power-On Self-Test (POST). There are 15 tests run in reverse order starting with number 15. 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 performed. A complete description of the 15 POST tests in included in the section "POST Failure" in the "Troubleshooting" chapter.

Tests 9 and 10 each take about 30 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 section "POST Failure" in the "Troubleshooting" chapter.

Default Settings

Catalyst 2100 is configured with the default settings shown in Table 4-1.

Table 4-1 : Default Settings and Their Menus

Catalyst 2100 Feature	Default Setting	Management Console Menu and Page
Switching mode	FastForward	"System Configuration" in the "Out-of-Band Management" chapter
Spanning-Tree Protocol	Enabled	"Spanning-Tree Configuration" in the "Out-of-Band Management" chapter
Addressing security	Disabled	"Port Addressing" in the "Out-of-Band Management" chapter
VLAN configuration	All ports belong to VLAN1	"VLAN Configuration" in the "Out-of-Band Management" chapter
Port monitoring	Disabled	"Monitoring Configuration" in the "Out-of-Band Management" chapter
Flooding unknown unicast packets	Enabled	"Port Addressing" in the "Out-of-Band Management" chapter
Flooding unregistered multicast packets	Enabled	"Port Addressing" in the "Out-of-Band Management" chapter
Full duplex	Disabled	"Port Configuration" in the "Out-of-Band Management" chapter
Assign IP address to Catalyst 2100	0.0.0.0	"IP Configuration" in the "Out-of-Band Management" chapter
Define trap manager	0.0.0.0	"Network Management (SNMP) Configuration" in the "Out-of-Band Management" chapter
Action on address violation	Suspend	"System Configuration" in the "Out-of-Band Management" chapter

If you find some of these terms unfamiliar, they are described in detail in the "Concepts" chapter. See the section "Configuration Menus" in the "Out-of-Band Management" chapter for instructions on changing the default settings. If you're using SNMP you can set these parameters according to the list of supported MIB objects found in the section "Standard MIBs and MIB Extensions" in the "In-Band Management" chapter.

Connecting to Catalyst 2100 Ports

Once Catalyst 2100 is installed you can begin connecting devices to its ports. Note that all UTP connections, whether 10Base T or 100Base TX, must be within 100 meters of Catalyst 2100.
