AVERTISSEMENT: Les ports RJ-45.

Il s’agit de prises
femelles blindées de données RJ-45. Vous ne pouvez pas
les utiliser comme prise de téléphone. Branchez unique­ment des connecteurs de données RJ-45 sur ces prises
femelles. Les câbles de données blindés ou non blindés,
avec les jacks blindés ou non blindés, l’un ou l’autre, peu­vent être branchés à ces prises de courant de données.

WARNUNG: RJ-45-Anschlüsse.

Dies sind abgeschirmte
RJ-45-Datenbuchsen. Sie können nicht als Telefon­anschlußbuchsen verwendet werden. An diesen Buchsen

oder unabgeschirmten Datenkabeln mit abgeschirmten
oder unabgeschirmten Klinkensteckern verbunden wer­den.

10BASE-T/100BASE-TX Ports

The Baseline 10/100 Switch has 12 (3C16464B) or 24 (3C16465B)
10/100Mbps auto-negotiating ports.

Ports 1-11 (3C16464B) or 1–23 (3C16465B) are MDIX ports. Each
can be connected to a device with an MDI port (such as a
workstation) using a normal ‘straight through’ TP (twisted pair)
cable. Alternatively, you can connect to a device with MDIX ports
using ‘cross-over’ TP cable.

Port 12 (3C16464B) or 24 (3C16465B) is ‘switch selectable’
MDI/MDIX usin g the MD I swit ch, as d escri bed in 2. Using this
port, you can connect to any other device without the need for
‘cross-over’ cable.

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 10Mbps 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 can be connected to either a 10BASE-T or a
100BASE-TX device.

I

f you connect two Baseline 10/100 Switch units together,
the link between them operates at 100Mbps 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).

To connect the Baseline 10/100 Switch to a SuperStack 3 hub
using a normal ‘straight through’ cable, connect any port on the
Baseline 10/100 Switch to the MDI/MDIX port on the hub, as
shown below. Ensure that the MDI switch on the hub is in (MDI).

An alternative method of connecting the Baseline 10/100 Switch
to a hub using a normal ‘straight through’ cable is to connect any
MDIX port on the hub to the MDI/MDIX port on the Baseline
10/100 Switch, ensuring that its MDI Switch is set to in (MDI).

You can us e ‘cross-over’ TP cable to connect any MDIX port on
the Baseline 10/100 Switch to any MDIX port on a hub.

3C16071, 3C16071A or 3C16071B) to this socket. An
appropriate power module and cable is required. The connector
on the Baseline 10/100 Switch is a Type 2 socket. For details,

follow the installation instructions in the guides that accompany
the Advanced RPS and the power module.

CAUTION: When connecting an RPS power module cable
to the unit, take off the protective cover by removing the
fixings with a suitable tool. Keep the cover and the fix­ings in a safe place. If you remove the RPS power module
cable at any time, you must replace the protective cover.

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 Mount ing the U nits

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.

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 u nit int o the 19 -inc h rack a nd se cure with suita ble
screws (not provided).

6

Reconnect all cables.

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.



That you are using a TP cable that is:

■

‘Straight through’, to connect an MDIX port to an
MDI port.

■

‘Cross-over’, to connect an MDIX port to an MDIX
port, or an MDI port to an MDI port.



The cable is not damaged.



If the connection is to a workstation, that the workstation’s
network interface is installed and configured correctly.

All Ac tivit y LEDs appea r to be lit co ntinua lly.

There m ay b e
broadcast storms on the network. 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 t o the docum enta tion t hat a ccomp anies the dev ice fo r
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:
