Table 2-1 GBIC Modules by Asanté
2.3.1 Installing a GBIC
GBICs are hot-swappable. This means that they can be inserted and removed while the switch is powered
on. However, please allow 40-60 seconds for the switch to recognize the module when it has been installed
while the switch is on.
1. Wearing an ESD (electro-static discharge) wrist strap, remove the GBIC module from its protective
packaging.
2. Verify that the GBIC is the correct type for the network (see the table above).
3. Grip the sides of the GBIC with the thumb and forefinger, and then insert the GBIC into the slot on
the face of the switch.
4. Slide the GBIC into the slot until it clicks into place.
5. Fiber GBIC modules: Remove the rubber plugs from the end of the GBIC module. Save them for
future use.
6. Attach the appropriate cable.
Note: After installing a GBIC 1000T module, the link LED may light even before a valid cable has been
connected. This is a normal condition for most 1000BaseT GBIC modules.
Note: Auto-negotiation must be disabled on a port in which a copper GBIC module is installed. Copper
GBICs themselves control auto-negotiation.

12
2.3.2 Removing a GBIC
Caution: GBIC 1000T modules run hot under normal operating conditions. When it has been removed from
the system, place it on a heat-resistant surface and allow the module to cool before handling.
Note: Unnecessary removals/insertions of a GBIC module will lead to premature failure of the GBIC
connector. The rated duty cycle for a GBIC module is 100 to 500 removals/insertions.
Follow the steps below to remove a GBIC interface from a Gigabit Ethernet module:
1. Disconnect the cable from the GBIC module.
2. Release the GBIC from the slot by simultaneously squeezing the locking tabs on both sides of the
GBIC.
3. Slide the GBIC out of the slot.
4. Fiber GBIC modules: Install the rubber plugs in the GBIC optical bores, and place the GBIC in
protective packaging.
2.3.3 GBIC Care and Handling
Follow these GBIC maintenance guidelines:
• GBICs are static-sensitive. To prevent ESD damage, follow normal board and component handling
procedures. Wear an ESD wrist strap
• Fiber GBIC modules are very sensitive to dust and contaminants. When they are not connected to
a fiber-optic cable, install the rubber plugs in the optical bores
• The ferrules of the optical connectors may pick up debris that can obstruct the optical bore. Use an
alcohol swab or equivalent to clean the ferrules of the optical connector
2.4 Installing the Optional Emergency Power Supply
To ensure increased reliability for mission-critical applications, the IC35516 can be equipped with a 12 VDC
emergency backup power supply (the IC35-EPS12, sold separately). When installed, the emergency power
supply is in standby mode. Should the primary unit fail, the DC backup automatically switches on and the
LED on the front panel lights. In addition, an SNMP fault notice is sent.
To verify the primary power status, use the Router# show system command. Under System Information,
you will see the power unit status.
System Information
------------------

PROM Image Version/Date: 1.01A/Nov 20 2002 20:24:10
DRAM Size: 64.0MB Flash Size: 8.0MB
Config NVRAM Size: 128KB Console Baud Rate: 9600 bps
Serial No. :
Power Unit Status = OK
Should the IC35-EPS12 become active due to a fault with the primary power, the unit should be swapped
out at the earliest convenience and sent for repair. The IC35-EPS12 is designed to be a temporary
replacement when the primary power fails, not a permanent replacement.
To install the optional power supply, simply attach the 12 VDC connector of the power supply to the jack
located in the center of the rear panel of the switch. Connect the power cord to the power supply and plug
the power cord into an outlet.
Important! The optional power supply becomes HOT under normal operating conditions. To avoid damage
or injury, set the power supply on a heat-resistant surface and USE CAUTION when handling the unit.

13
2.5 Connecting Power
Important: Carefully review the power requirements (Chapter 2.1.3) before connecting power to the switch.
Use the following procedure to connect power to the switch:
1. Plug one end of the supplied power cord into the power connector on the back of the switch.
2. Plug the other end into a grounded AC outlet.
3. Turn on the switch’s power. The power LED will begin its initialization process.
The front panel LEDs blink and the power LED illuminates when it has initialized. The switch is ready for
connection to the network.
Important: If the power does not come on, check the next section to ensure that the correct cabling is used.
2.6 Connecting to the Network
The switch may be connected to an Ethernet network with the switch powered on or off. Use the following
procedure to make the network connections:
1. Connect the network devices to the switch, following the cable guidelines outlined below.
2. After the switch is connected to the network, it can be configured for management capabilities (see
the following chapters for information on configuration).
2.6.1 10/100/1000BaseT Ports Cabling Procedures
The 10/100/1000 ports on the switch allow for the connection of 10BaseT, 100BaseTX, or 1000BaseT
network devices. The ports are compatible with IEEE 802.3 and 802.3u standards.
Important: The switch must be located within 100 meters of its attached 10BaseT or 100BaseTX devices.
Use the following guidelines to determine the cabling requirements for the network devices:
• Connecting to Network Station: Category 5 UTP (Unshielded Twisted-
Pair) straight-through cable (100 meters maximum) with RJ-45 connectors
• Connecting to Repeater/Hub/Switch’s Uplink port: Category 5, UTP
straight-through cable (100 meters maximum) with RJ-45 connectors
Note: These switches have no specific uplink ports. All 10/100/1000 ports on these
switches are auto-sensing MDI/MDI-X. This advanced feature means that when the
ports are operating at 10/100Mbps, they will automatically determine whether the device at the other end of
the link is a hub, switch, or workstation, and adjust its signals accordingly. No cross-over cables are
required.
Although 10/100BaseT requires only pins 1, 2, 3, and 6, Asanté strongly recommends cables with all 8 wires
connected as shown in Table 2-2 below.

14
1000BaseT requires that all four pairs (8 wires) be connected correctly, using Category 5 or better
Unshielded Twisted Pair (UTP) cable (to a distance of 100 meters). Table 2-2 shows the correct pairing of all
eight wires.

120 kilometers (393,701 feet) long
• 1000BaseT: Category 5 or better Unshielded Twisted Pair (UTP) cable to a distance of 100 meters
(328.1 feet) long
When attaching a workstation to the switch, a standard straight-through CAT5 cable may be used, even
when the workstation is attached via a patch panel. No crossover cable is needed with the MDX/MDI ports.
It is recommended that the switch be kept off the network until proper IP settings have been set.
2.7 Setup
In order to configure the switch, connect to it through a console (out-of-band management), running a
terminal emulation program, such as HyperTerminal.
2.7.1 Connecting to a Console
To connect the switch to a console or computer, set up the system in the following manner:
1. Plug power cord into the back of switch.
2. Attach a straight-through serial cable between the RS232 console port and a COM port on the PC.
3. Set up a HyperTerminal (or equivalent terminal program) in the following manner:
• Open the HyperTerminal program, and from its file menu, right-click on Properties
• Under the Connect To tab, choose the appropriate COM port (such as COM1 or COM2)

15
• Under the Settings tab, choose VT100 for Emulation mode
• Select Terminal keys for Function, Arrow, and Ctrl keys. Be sure the setting is for Terminal keys,
NOT Windows keys
• Back under the Connect To tab, press the Configuration button
• Set the data rate to 9600 Baud
• Set data format to 8 data bits, 1 stop bit and no parity
• Set flow control to NONE
Now that terminal is set up correctly, power on the switch (boot sequence will display in terminal.)
After connecting to the console, a prompt like the following will appear:
User Access Verification
Password:
By default, the initial password for access via console and telnet is Asante (case-sensitive). See the
following section for setting new passwords on the terminal lines.

16
2.8 Setting Passwords
The switch ships with a default of no enable password, which allows anyone on the network access to
various privilege levels. To prevent unauthorized changes to the switch’s configuration, you should set an
enable password for access to switch management. Follow the example below to assign a privileged
password.

2.9 Configuring an IP Address
The switch ships with the default IP address 192.168.0.1/24. Connect via the serial port in order to assign
the switch an IP address on your network.
The physical ports (or switchports) of the IC35516 are L2 ports, and cannot have an IP address assigned to
them. By default, each switchport belongs to VLAN 1, a virtual interface (veth1) that may be assigned a
primary, as well as any number of secondary, IP addresses. Use the following instructions to configure an IP
address to the switch. The network administrator may later assign primary IP addresses to any other VLAN
created.
Follow the steps below to change the switch’s IP address.
1. Connect to the console and press Enter at the Password prompt, as described above.
2. The screen will display the user mode prompt, Router>.
3. Type enable. The new prompt is Router#.
4. Type configure terminal. The new prompt is Router(config)#.
5. The default IP address is assigned to the veth1 interface. Type interface veth1. The new prompt is
Router(config-if-veth1)#.
6. Type ip address and the new address. Your screen will look like this example:
Router> enable
Router# configure terminal
Router(config)# interface veth1
Router(config-if-veth1)# ip address 192.168.123.254 255.255.255.0
Router(config-if-veth1)# end
Router# show interface veth1
Veth1 is up, line protocol is up
Hardware is virtual interface VLAN 1, address is 00:00:94:D2:56:FA
Encapsulation ARPA, Flags: <UP,BROADCAST,RUNNING,MULTICAST>
inet 192.168.123.254/24 broadcast 192.168.123.255
ARP Type: ARPA, ARP Timeout: 14400 seconds
Router# write file
Writing current-config to startup-config. Please wait.
Configuration saved to startup-config file
Router#
It is also acceptable to enter the subnet mask by typing ip address 192.168.123.254/24. Use the
show interface veth1 command from privileged mode to see the new IP address. The new IP address
automatically writes over the default IP address.
See Chapter 5 for more information on assigning IP addresses to interfaces.
2.9.1 Setting a Default IP Gateway Address
To define the default IP gateway for the switch, insert a static route:
Router(config)# ip route 0.0.0.0 255.255.255.255 <gateway IP> <mask>

2.10 Restoring Factory Defaults
If you ever need to restore the switch to its factory default settings, follow the commands shown in the
following screen.
Router> enable
Router# reload ?
factory-default Reset ALL system parameters to factory default
<cr>
Router# reload factory-default
The switch is now ready for configuration. Refer to the following chapters for management and configuration
information.
2.11 System Boot Parameters
The IC35516 has two boot banks to store its runtime code. You can select which bank will be used for the
next boot with the following command:
Router(config)# boot system flash {bank1|bank2}

Chapter 3. Understanding the Command Line Interface (CLI)
The switch utilizes Command Line Interface (CLI) to provide access to several different command modes.
Each command mode provides a group of related commands.
After logging into the system, the user is automatically in the user top (user EXEC) mode. From the user top
mode you can enter into the privileged top (privileged EXEC) mode. From the privileged EXEC level, you
can access the global configuration mode and specific configuration modes: interface, router, and route-map
configuration. Entering a question mark (?) at the system prompt allows you to obtain a list of commands
available for each command mode. Almost every router configuration command also has a no form. You
can use the no form to disable a feature or function. For example, ARP is enabled by default. Specify the
command no arp to disable the ARP table (see section 3.7).
Document Conventions
Command descriptions use the following conventions:
• Vertical bars ( | ) separate alternative, mutually exclusive, elements
• Square brackets ([ ]) indicate optional elements
• Braces ({ }) indicate a required choice
• Braces within square brackets ([{ }]) indicate a required choice within an optional element
• Boldface indicates commands and keywords that are entered literally as shown
• Italics indicate arguments for which you supply values
Access Each Command Mode
The following sections describe how to access each of the CLI command modes:
• User Top Mode: Router>
• Privileged Top Mode: Router#
• Global Configuration Mode: Router(config)#
• Interface Configuration Mode: Router(config-if-IFNAME)#
• Router Configuration Mode: Router(config-RTNAME-router)#
• Route-Map Configuration Mode: Router(config-route-map)#
3.1 User Top (User EXEC) Mode
After you log in to the router, you are automatically in user top (user EXEC) command mode. The user-level
prompt consists of the host name followed by the angle bracket (>):
Router>
The default host name is Router unless it has been changed during initial configuration, using the setup
command.
The user top commands available at the user level are a subset of those available at the privileged level. In
general, the user top commands allow you to connect to remote devices, change terminal settings on a
temporary basis, perform basic tests, and show system information.
To list the commands available in user top mode, enter a question mark (?). Use a space and a question
mark (?) after entering a command to see all the options for that particular command.
Command Purpose
? Lists the user EXEC commands.
show ? Lists all the options available for the given
command.

20
User top commands:
Router> ?
enable Turn on privileged mode command
exit Exit current mode and down to previous mode
help Description of the interactive help system
ping Send echo messages
quit Exit current mode and down to previous mode
show Show running system information
tracert Trace route to destination
cls Clear screen
Router>
You may also enter a question mark after a letter or string of letters to view all the commands that start with
that letter (with no space between the letter and the question mark). See section 3.8.2.
3.2 Privileged Top (Privileged EXEC) Mode
Because many of the privileged commands set the system configuration parameters, privileged access can
be password protected to prevent unauthorized use. The privileged command set includes those commands
contained in user EXEC mode, as well as the configure command through which you can access the
remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as
debug.
The following example shows how to access privileged EXEC mode. Note that the prompt changes from
Router> to Router#:
Router> enable
Password:
Router#
Command Purpose
Router> enable [password]Enters the privileged EXEC mode.
Router# ? Lists privileged EXEC commands.
If the user has set a password, the system prompts for it before allowing access to privileged EXEC mode. If
an enable password has not been set, the enable mode can be accessed only through the console. The
user can enter the enable password global configuration command to set the password that restricts
access to privileged mode.
To return to user EXEC mode, use the following command:
Command Purpose
Router# disable Returns you to user EXEC mode from privileged
EXEC mode.
In general, the top (privileged) commands allow you to change terminal settings on a temporary basis,
perform basic tests, and list system information. To list the commands available in top mode, enter a
question mark (?) at the prompt, as shown in the following example. Enter a question mark (?) after a
command to see all the options for that command.
