For systems without a power switch, line voltages are present within the power supply when the power cord is connected.


Physically Installing the IE2100 Series

The IE2100 Series can be placed on a desktop or mounted in a metal rack. The location and layout of your equipment rack or wiring room is extremely important for proper system operation. Refer to "Preparing Your Site for Installation" section on page 2-4 for more information.

How to Install the IE2100 Series in a Rack

This section describes how to install the IE2100 Series in a rack and assumes you are rack-mounting the system in a standard 19-inch equipment rack. You can install the IE2100 Series with either the front or back panel facing the front of the rack.

A rack-mount kit is included for mounting the system in a standard 19-inch equipment rack with two unobstructed outer posts. This kit is not suitable for use with other racks, such as telco-type equipment racks, or those with obstructions (such as a power strip) that could impair access to the hard disk and power supplies.


Caution Before installing the IE2100 Series in a rack, read the "Preparing Your Site for Installation" section on page 2-4 to familiarize yourself with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.


Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:


This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

To install the IE2100 Series in a rack:


Step 1 Measure the rack to verify that the system will fit.

a. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The depth must be at least 19-1/4 in. (48-7/8 cm), but not greater than 32 in. (81-1/4 cm).

b. Measure the space between the inner edges of the left front and right front mounting posts to verify that it is 17-3/4 in. (45 cm) wide. The chassis is 17-1/4 in. (43-3/4 cm) wide and must fit between the mounting posts.

Step 2 Attach the L brackets to the sides of the chassis using the provided screws so that the L-bracket mounting surfaces are even with the front or back panel of the chassis, depending on which way you want to install it. See Figure 3-1.

Figure 3-1 Attaching the L Brackets


Caution When installing the chassis in the rack, make sure that the heavier equipment is at the bottom of the rack to maintain a low center of gravity and prevent the rack from becoming top-heavy and tipping over.

Step 3 Position the chassis in the rack:

If the chassis front panel is in the front of the rack, insert the rear of the chassis between the rack posts, and align the four mounting holes in the L bracket with four mounting holes in the equipment rack.

If the chassis rear is in the front of the rack, insert the front of the chassis between the mounting posts, and align the four mounting holes in the L bracket with the four mounting holes in the equipment rack.

See Figure 3-2.

Figure 3-2 Attaching the IE2100 Series to a Rack

Step 4 Secure the system in the rack by installing the provided screws through the elongated holes in the L bracket and into the threaded holes in the mounting post. Refer to Figure 3-2.

Step 5 (Optional) Install the cable guide by screwing it into the threaded mounting hole of one of the L brackets using the provided screw.


How to Install the IE2100 Series on a Desktop

You can place the system on a desktop or other flat, stable surface. Install the provided self-adhesive rubber feet in the indentations on the bottom of the chassis, as shown in Figure 3-3, before placing the system on a desktop.

Figure 3-3 Installing Desktop Mounting Rubber Feet

Connecting to Power Source


Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.



Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.



Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.


Connect the AC power receptacle to the AC power source with the provided power cable.

Connecting Cables

Wiring hubs (peripherals for cabling installations) provide the connection logic unique to Fast Ethernet cables used by the IE2100 Series. Unshielded twisted pair (UTP) copper wire connects the IE2100 Series to the network and distributes the network connections to wall jacks near each piece of network equipment.


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.



Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:


This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

To connect the cables:


Step 1 Plug the network connection into the Ethernet 0 port.

Step 2 Connect a console to the console port using the supplied serial cable.


How to Power On the System

Power on and boot the system:


Step 1 Move the power switch to the on position.

Step 2 Open a window for the system console, using a terminal emulation program if necessary.

The system begins booting and sends messages to the console window. When the login prompt appears, you can configure the system.


How to Configure the System Using the Setup Program

You must run the setup program when you boot the system for the first time.

You must connect to the system using the console port to use the setup program. You cannot connect to it using Telnet because the network interface is not configured when the setup program is running.

How to Verify the Configuration on the IE2100 Series

After you run the setup program, verify that the IE2100 Series is configured correctly:


Step 1 Log in with the username and password you created during setup.

If you cannot log in, refer to the "Cannot Log In to the System" section on page A-1 for troubleshooting information.

Step 2 Enter the following command to verify that the system can obtain DNS services from the network:

# nslookup dns-name

where dns-name is the DNS name of a host that is registered in DNS. If the system cannot obtain the IP address of the host from DNS, run the setup program again and verify the correct IP address for the DNS Server(s).

Step 3 Enter the following command to verify that the system can communicate with the network:

# ping ip-address

where ip-address is the IP address of a host that is accessible on the network. A DNS server is an excellent host to ping because it should always be running and accessible.

If the system cannot communicate with the network, refer to the "System Cannot Connect to the Network" section on page A-2 for troubleshooting information.

Step 4 Enter the command ifconfig -a to verify that the configuration is as you expected.

Step 5 Connect to the system using a web browser to verify HTTP connectivity:

Enter the system IP address in a web browser.

For example, if the system IP address is 10.1.58.5, enter the URL http://10.1.58.5/config/login.html in a web browser.

If you cannot connect to the system using a web browser, refer to the "Cannot Connect to the System Using a Web Browser" section on page A-3 for troubleshooting information.

Step 6 Enter the exit command to log out of the system.


How to Verify the Installation of the Configuration Registrar

Once the system has been installed, you can verify the installation of the Configuration Registrar by following these steps:


Step 1 Go to a different computer and bring up a web browser.

The Configuration Registrar supports Microsoft Internet Explorer 5.0 or Netscape 4.7 or later.

Step 2 On the net-site window enter the URL for the Configuration Registrar.

For example: http://<ip_address>/config/login.html

where: ip_address is the IP address you entered during IE2100 Series setup. You can use the hostname if the name has been defined and registered within your DNS domain.

The Configuration Registrar login page appears (see Figure 3-4).

Step 3 Enter the Configuration Registrar Userid and Password that you entered during IE2100 Series setup.

A message page appears.

Step 4 Click Continue.

The Home page appears (see Figure 3-5).

If you have reached the Configuration Registrar Home page, you have verified the successful installation on the Configuration Registrar.

Re-Configuring System Network Information

To reconfigure system network information, follow these steps:


Step 1 Initiate a system backup.

For information about backup, see "Backup and Restore" section on page 4-36.

Step 2 Login as root.

Use your root password.

Step 3 Type ResetConfig.

This program clears your system configuration and returns you to setup.


Caution When running setup again, you can change values for only IP addresses, net mask, default gateways, and DNS name service. For hostname, country code, location code the configuration server username and password, you must enter the same values used for the initial setup.


Registering the System in DNS

Register the system in DNS, using the system hostname as its DNS name.


Caution If you do not register the system in DNS using the system hostname as its DNS name, network connectivity problems will occur.

Events are sent to the router with the hostname as the identifier, not the IP address. Consequently, if the IE2100 Series is not registered in DNS, the routers are not able to find it and cannot download configurations.

Installing a Replacement IE2100 Series

This section describes the tasks you should perform when installing a replacement IE2100 Series (a new unit intended to replace an existing unit). These tasks are in addition to the installation and configuration processes described in the "How to Configure the System Using the Setup Program" section.
