INTRODUCTION
The SuperStack® 3 Baseline 10/100 Switch is a versatile,
easy-to-use unmanaged switch. It is ideal for users who want the
high-speed performance of 10/100 switching but do not need
sophisticated management capabilities. The Baseline 10/100
Switch is shipped ready for use. No configuration is necessary.
The Baseline 10/100 Switch has 16 or 24 shielded RJ-45,
10/100 Mbps auto-negotiating ports on the front panel. Each port
automatically determines the speed and duplex mode of the
connected equipment and provides a suitable switched
connection. Each port also supports automatic MDI/MDI-X
detection.
The Baseline 10/100 Switch is suited for office use where it can
be free standing, or rack mounted (in a wiring closet or
equipment room).

10BASE-T/100BASE-TX Ports
The Baseline 10/100 Switch has 16 (3C16470) or 24
(3C16471) 10/100 Mbps auto-negotiating ports.
To connect a device to the Baseline 10/100 Switch, use
Category 5 unshielded or shielded (screened) 100 Ohm
TP cable (or Category 3 cable for a 10 Mbps connection).
The maximum length of cable for each connection is
100m (328ft). Connect one end of the cable to an RJ-45
port on the Baseline 10/100 Switch, and the other end to
the appropriate RJ-45 port on the connecting device.
Each port on the Baseline 10/100 Switch is
auto-negotiating: its speed and duplex mode (half duplex
or full duplex) are automatically determined by the
capabilities of the connected device.

Each port supports automatic MDI/MDI-X detection and
can be connected to either a 10BASE-T or a 100BASE-TX
device.
The Switch offers priority queuing, which means all
packets that are received are examined to see if they have
been priority encoded. If a packet has been then the
Switch will read the priority level and determine whether
the packet should be directed through the normal or high
priority channel. This feature can be useful for example
during excessive loads when one type of traffic may
require priority over another. The Switch is configured to
comply with 802.1p, VLAN tagged frames.
Traffic prioritization ensures that high priority data is
forwarded through the Switch without being delayed by
lower priority data. It differentiates traffic into classes and
prioritizes those classes automatically. Traffic prioritization
uses the multiple traffic queues that are present in the
hardware of the Switch to ensure that high priority traffic
is forwarded on a different queue from lower priority
traffic, and is given preference over that traffic. This
ensures that time-sensitive traffic gets the highest level of
service. The 802.1D standard specifies eight distinct levels
of priority (0 to 7), each of which relates to a particular
type of traffic. The priority levels and their traffic types
are shown in the following table.
Priority Level Traffic Type

milliseconds latency and jitter.
The traffic prioritization feature supported by the Switch
is compatible with the relevant sections of the IEEE
802.1D standard (incorporating IEEE 802.1p).
If you connect two Baseline 10/100 Switch units together,
the link between them operates at 100 Mbps full duplex.
You must use Category 5 cable when connecting the
units.

CAUTION: The Baseline 10/100 Switch supports full
duplex auto-negotiation. If the connected device does not
!
support auto-negotiation, the Switch will operate in half
duplex mode (even if the device is operating in full duplex
mode). In such a configuration, you may notice some
degradation of network performance. 3Com recommends
that you use devices that are capable of auto-negotiation
(and that you ensure that auto-negotiation is enabled, if
it is a configurable option).

INSTALLING THE SWITCH
Positioning the Baseline 10/100 Switch
CAUTION: If installing the Baseline 10/100 Switch in a
stack of different size SuperStack 3 units, the smaller
!
units must be installed above the larger ones. Do not
have a free-standing stack of more than six units.
When deciding where to position the Baseline 10/100 Switch
ensure that:
It is accessible and cables can be connected easily.
Cabling is away from sources of electrical noise such as
radios, transmitters and broadband amplifiers, and away from
power lines and fluorescent lighting fixtures.
The Switch is situated away from sources of electrically
conductive dust, for example laser printers.
The AC supply used by the Switch is separate to those used
by units that generate high levels of AC noise, for example air
conditioning units and laser printers.
Water or moisture cannot enter the case of the unit.
Air flow around the unit and through the vents in the side of
the case is not restricted (3Com recommends that you
provide a minimum of 25 mm (1 in.) clearance).
To prolong the operational life of your units:
Never stack units more than six high if free-standing, and
ensure that cables are supported so that they do not cause
the stack to fall over.
Do not place objects on top of any unit or stack.
Do not obstruct any vents at the sides of the case.

MOUNTING KIT INSTRUCTIONS
Introduction
The Baseline 10/100 Switch is supplied with two mounting
brackets and four screws. These are used for rack-mounting the
unit. When mounting the unit, you should take note of the
guidelines given in “Positioning the Baseline 10/100 Switch” on
page 3.
Rack Mounting the Units
The Baseline 10/100 Switch is 1U high and will fit a standard
19-inch rack.
CAUTION: Disconnect all cables from the unit before
continuing. Remove the self-adhesive pads from the
underside of unit, if already fitted.
1 Place the unit the right way up on a hard, flat surface with
the front facing towards you.
2 Locate a mounting bracket over the mounting holes on one
side of the unit (refer to the figure following step 6).
PROBLEM SOLVING
Refer to the information about LEDs given earlier in this guide to
see if the problem can be identified and rectified. Here are some
common problems that can occur:
Link Status LED not lit for a port that has a connection.
There is a problem with this connection. Check that:
The device being connected to is powered on and operating
correctly.
The cable is connected at both ends.
The cable is not damaged.
If the connection is to a workstation, that the workstation’s
network interface is installed and configured correctly.
All ports appear to show continual activity. There may be
broadcast storms on the network.
3 Insert the two screws supplied in the mounting kit and fully
tighten with a suitable screwdriver.
4 Repeat the two previous steps for the other side of the unit.
5 Insert the unit into the 19-inch rack and secure with suitable
screws (not provided).
6 Reconnect all cables.
Remove port connections one at a time, waiting a few seconds
between each port. If the LEDs go off after removing a port
connection, the device that was connected to that port is
introducing an excessive amount of broadcast frames to the
network (some pieces of network equipment operate by sending
out broadcast frames regularly). Refer to the documentation that
accompanies the device for information on disabling the
broadcast operation.
If the problem persists and the unit still does not operate
successfully, contact your supplier with the following information
before returning the unit:
