AVERTISSEMENT: Les ports RJ-45. Ceux-ci sont

protégés par des prises de données. Ils ne peuvent pas

être utilisés comme prises de téléphone conventionnelles

standard, ni pour la connection de l’unité à un réseau

téléphonique central privé ou public. Raccorder seulement

connecteurs de données RJ-45, systèmes de réseaux de

téléphonie ou téléphones de réseaux à ces prises. Il est

possible de raccorder des câbles protégés ou non

protégés avec des jacks protégés ou non protégés à ces

prises de don.

WARNUNG: RJ-45-Porte. Diese Steckdose sind

geschützte Datensteckdosen. Sie dürfen weder wie

normale traditionelle Telefonsteckdosen noch für die

Verbindung der Einheit mit einem traditionellem privatem

oder öffentlichem Telefonnetzwerk gebraucht werden.

Nur RJ-45-Datenanscluße, Telefonnetzsysteme or

Netztelefone an diese Steckdosen anschließen. Entweder

geschützte oder ungeschützte Buchsen dürfen an diese

Datensteckdosen angeschlossen werden.

ADVERTENCIA: puertos RJ-45. Son conectores de datos

RJ-45 blindados. No pueden utilizarse como tomas de

teléfono tradicionales estándar ni para conectar la unidad

a una central de conmutación PBX tradicional ni a una

red telefónica pública. Conecte sólo conectores de datos

RJ-45, sistemas de telefonía de red local o teléfonos de

red local a estas tomas. Es posible conectar cables de

10BASE-T/100BASE-TX Ports

The Switch has 16 (3C16470B) or 24 (3C16471B) 10/100 Mbps

auto-negotiating ports. To connect a device to the 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 Switch, and the other

end to the appropriate RJ-45 port on the connecting device.

Each port on the 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.

If you connect two 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 Switch supports full duplex auto-negotia-

tion. If the connected device does not support auto-nego-

tiation, 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 net-

work 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 con-

figurable option).

mount the unit.

If the unit is to be part of a free standing stack, apply the pads to

each marked corner area on the underside of the unit. Place the

unit on top of the lower unit, ensuring that the pads locate with

the recesses of the lower unit.

Rear Panel Connections

6 Power Supply

The Switch automatically adjusts to the supply voltage. Only use

the power cord that is supplied with the Switch.

Positioning the Switch

CAUTION: If installing the Switch in a stack of different

size Baseline units, the smaller units must be installed

above the larger ones. Do not have a free-standing stack

of more than six units.

CAUTION: Please read the following safety information

carefully before installing the Switch.

AVERTISSEMENT: Veuillez lire à fond l'information de la

sécurité suivante avant d'installer le Switch.

WARNUNG: Bitte unbedingt vor dem Einbauen des

Switches die folgenden Sicherheitsanweisungen durchle-

sen.

ATTENZIONE: Vi preghiamo prima di leggere con attenzi-

one tutte le informazioni concernenti l'installazione

dell'interruttore.

When deciding where to position the 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.

Rack Mounting

The Switch can be mounted in a 19-inch equipment rack using

the Mounting Kit. Refer to “Mounting Kit Instructions” on

page 5.

Power Up

Use the following sequence to power up the Switch:

1 Check the network connections and cables.

2 Connect the power supply cable to the appropriate power

socket on the rear panel of the unit; refer to 6 Power

Supply

3 Connect the plug to the power supply outlet socket and

switch on the power supply at the socket.

When the switch is powered on, the Power LED should be lit on

green. If it is not, refer to 4 Power LED.

Spot Checks

At frequent intervals you should visually check the Switch. Regular

checks can give you an early warning of a possible failure; any

problems can then be attended to when there will be least effect

on users. Check that all external cabling connections are secure

and that no cables are pulled taut.

If you experience any problems operating the Switch, refer to “Prob-

lem Solving” on page 3.

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.

Remove port connections one at a time, waiting a few seconds

between each port. If the LEDs go off after disconnection, the

device that was connected to that port is introducing an excessive

amount of broadcast frames to the network (some pieces of net-

work equipment operate by sending out broadcast frames regu-

larly). 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 success-

fully, contact your supplier. Include the product number and serial

number (printed on a label supplied with the unit) as well as a

brief description of the fault.

Status Meaning

On Green The unit is powered on and ready for use.

Off The unit is not receiving power:

■ Check the power cord is connected correctly.

■ If the unit still does not operate, contact your supplier.
