interference to radio communications. It has been tested and found to comply
with the limits for a Class A computing device pursuant to Subpart B of Part 15
of FCC Rules, which are designed to provide reasonable protection against such
interference when operated in a commercial environment. Operation of this
equipment in a residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever measures may be
required to correct the interference.

CHAPTER 1
QUICK START

Introduction
SMC’s TigerSwitch™16 family consists of a set of three manage-
able Ethernet switches with Fast Ethernet connection capability.
Each switch provides sixteen 10BASE-T ports for connection to
Ethernet hubs, servers and workstations. Each switch also
includes two ports for connection to Fast Ethernet devices. The
switch, depending on the model chosen, will contain either two
100BASE-TX ports, two 100BASE-FX ports or one 100BASE-TX
port and one 100BASE-FX port. The Fast Ethernet port types
found on each model are listed below:
◆Model SMC6516TT
• two 100BASE-TX ports with Auto-Negotiation
◆Model SMC6516FF
• two 100BASE-FX ports
◆Model SMC6516TF
• one 100BASE-TX port with Auto-Negotiation
• one 100BASE-FX port
This chapter provides a set of instructions designed to help you
get up and running quickly and without excessive details. The
steps in each of the two sections refer to other locations in the
manual where further information may be found.
The first section, “Connecting the Switch,” provides a list of
instructions for powering up the switch and making network
connections, and also for setting up a PC to configure and
monitor the switch out-of-band.
The second section, “Configuring the Switch for SNMP and
Telnet Management,” discusses the steps required to set up the
switch for in-band management.
1-2
QUICK START

Connecting the Switch
1. Power up the PC to be used to configure and monitor the
switch out-of-band. After loading this PC with communica-
tions software, set your terminal or communications program
to the following parameters: 9600, n, 8, 1 (9600 baud, no
parity, 8 data bits, 1 stop bit). (See Appendix C for the
Windows Terminal program parameter settings.)
2. Plug the female end of a DB-9 standard null-modem cable
into the Console connector on the front panel of the switch.
Attach the other end of the cable to the serial connector on
the PC (typically COM1 or COM2). (See “Connecting to the
Console Port” in Chapter 4.)
3. Connect one end of the 3-pin AC power cord supplied with
the switch to the power receptacle on the rear of the chassis,
and the other end to a grounded power outlet. (See
“Connecting to a Power Source” in Chapter 4.) Make note of
the diagnostic test results that appear on the PC attached to
the Console port.
4. If you have purchased a Redundant Power Unit (RPU), plug
the 14-pin connector from the RPU cable into the mating
connector on the rear panel of the switch. (See the guide
supplied with the RPU.)
5. Connect the front-panel 10BASE-T ports to hubs, servers and
power users. Once a valid connection has been made, the
green LED above the port will light. (See “Making Network
Connections” in Chapter 4.)
6. Connect each front-panel 100BASE-TX and 100BASE-FX port
to a Fast Ethernet power user, server, workgroup or back-
bone. When a valid connection has been made, the green
LED for that port will light. (See “Making Network
Connections” in Chapter 4.)

7. Press the Esc key on the terminal or PC. The Main Menu
will appear on the screen.

You may now set a variety of configuration options, such as full-
duplex mode on the 10BASE-T ports, a password for the
Console interface, and Spanning Tree and Address Aging para-
meters. You may also select various options for monitoring the
performance of the unit out-of-band. These are described in
Chapter 5.
To set up the unit for in-band management via SNMP or Telnet,
continue with Step 8.

IP address and Subnet Mask are assigned automatically.
Make a note of the IP address and skip to Step 12.
Otherwise, select “IP Configuration” from the menu. The IP
Configuration Menu will appear (see Figure 1-3).
10. To manually enter the IP address of the switch, you must
first disable DHCP. Then, select “Switch IP Address” from
the menu and enter the address to be assigned to the switch.
This should be an administratively assigned address. (See
“Configuring the IP Address” in Chapter 5.)
11. Select “Subnet Mask” from the menu and enter the subnet
mask for the IP address entered in Step 10. If applicable,
also enter the Gateway IP address.

are factory-set to “public.” If the name “public” is also used
for both management console names, connect to the IP
address assigned in Step 10 and then skip to Step 15.
Otherwise, continue with Step 14.
