10BASE-T/100BASE-TX Po rts

The Baseline 10/100 Switch 24 Port 10BASE-T/100BASE-TX plus
1-Port 1000BASE-T has 24 10/100Mbps auto-negotiating ports.

Ports 1–23 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 cab le.

Port 24 is ‘switch selectable’ MDI/MDIX us ing the MDI swit ch, as
described in 2. Using this port, you can connect to any other
device withou t the need fo r ‘cross-over’ cab le.

Ports 1 to 24 are auto-negotiating: their 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.

CAUTION:

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).

1000BASE-T Port

Port 25 is a 1000BASE-T port capable of auto-negotiation with
the connected port to operate at 1000BASE-T full duplex. It
auto-senses an MDI/MDIX connection and can be used to connect

RJ-45 ports.

The Baseline 10/100 Switch supports full

to either another 1000BASE-T switch port or to a 1000BASE-T
server or workstation without additional configuration.

Connecting to a Netw ork Device

To connect a device to the Baseline 10/100 Switch 24 Port
10BASE-T/100BASE-TX plus 1-Port 1000BASE-T, 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.

Connecting to another Switch or Hub

If you connect two Baseline 10/100 Switch 24 Port
10BASE-T/100BASE-TX plus 1-Port 1000BASE-T units
together, 3Com recommends that you use the
1000BASE-T ports on both units for the link. You must
use Category 5 cable when connecting the units.

1000BASE-T connection:

24 Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T to
another Switch using the 1000BASE-T port, use a normal ‘straight
through’ cable and connect each end to the 1000BASE-T port on
each unit.

100BASE-TX connection:

24 Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T to a
SuperStack 3 hub using a normal ‘straight through’ cable ,
connect any port on the Baseline 10/100 Switch 24 Port
10BASE-T/100BASE-TX plus 1-Port 1000BASE-T 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.

ECOMMENDATIONS

Positioning the Switch

When deciding where to position the Baseline 10/100 Switch 24
Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T ensure:



It is accessible and cables can be connected easily.



Cabling is away from sources of electrical noise. These include
lift shafts, microwave ovens, and air conditioning units. Elec­tromagnetic fields can interfere with the signals on copper
cabling and introduce errors, therefore slowing down your
network.



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 recommend that you provide
a minimum of 25mm (1in.) clearance).



The air is as free from dust as possible.



Temperature operating limits are not likely to be exceeded. It
is recommended that the unit is installed in a clean, air condi­tioned environment.

It is always good practice to wear an anti-static wrist
strap when installing network equipment, connected to a
ground point. If one is not available, try to keep in con­tact with a grounded rack and avoid touching the unit's
ports and connectors, if possible. Static discharge can
cause reliability problems in your equipment.

Rack Mounting or Free Standing

The unit can be mounted in a 19-inch equipment rack using the
Mounting Kit. Refer to “Mounting Kit Instructions” on page 4, or
it can be free standing. Do not place objects on top of the unit or
stack.

CAUTION: If installing the Baseline 10/100 Switch 24
Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T in a
free standing 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.

3

Power Supp ly

Power problems can be the cause of serious failures and down­time in your network. Ensure that the power input to your system
is clean and free from sags and surges to avoid unforeseen net­work outages. We recommend that you install power condition­ing, especially in areas prone to black outs, power dips and
electrical storms.

The unit is intended to be grounded. Ensure it is connected to
earth ground during normal use. Installing proper grounding helps
to avoid damage from lightning and power surges.

Power Up

Use the following sequence to power up the Baseline 10/100
Switch 24 Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T:



Check the network connections and cables.



Connect the power supply cable to the appropriate power
socket on the rear panel of the unit; refer to 7 or 8.



Connect the plug to the power supply outlet socket and
switch on the power supply at the socket. If you are using

the Advanced Redundant Power System, ensure it is pow­ered on.

When the switch is powered on, the Power/Self Test LED should
first flash green, then stay lit. If it does not, refer to 6.

Spot Checks

At frequent intervals you should visually check the Baseline
10/100 Switch 24 Port 10BASE-T/100BASE-TX plus 1-Port
1000BASE-T. 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 the following:

Cabling Check that all external cabling connections are

secure and that no cables are pulled taut.

Cooling fans Where possible, check that the cooling fans are

operating by listening to the unit. The fans are
fitted near to the front right hand side of the
unit (when viewed from the front).

If you experience any problems operating the Baseline 10/100 Switch 24 Port 10BASE-T/100BASE-TX plus 1-Port 1000BASE-T, refer to “Problem Solving” on page 4.
